+  /**
+    An instance of `Application` is the starting point for every Ember
+    application. It helps to instantiate, initialize and coordinate the many
+    objects that make up your app.
+  
+    Each Ember app has one and only one `Application` object. In fact, the
+    very first thing you should do in your application is create the instance:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    window.App = Application.create();
+    ```
+  
+    Typically, the application object is the only global variable. All other
+    classes in your app should be properties on the `Application` instance,
+    which highlights its first role: a global namespace.
+  
+    For example, if you define a view class, it might look like this:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    App.MyView = Ember.View.extend();
+    ```
+  
+    By default, calling `Application.create()` will automatically initialize
+    your application by calling the `Application.initialize()` method. If
+    you need to delay initialization, you can call your app's `deferReadiness()`
+    method. When you are ready for your app to be initialized, call its
+    `advanceReadiness()` method.
+  
+    You can define a `ready` method on the `Application` instance, which
+    will be run by Ember when the application is initialized.
+  
+    Because `Application` inherits from `Ember.Namespace`, any classes
+    you create will have useful string representations when calling `toString()`.
+    See the `Ember.Namespace` documentation for more information.
+  
+    While you can think of your `Application` as a container that holds the
+    other classes in your application, there are several other responsibilities
+    going on under-the-hood that you may want to understand.
+  
+    ### Event Delegation
+  
+    Ember uses a technique called _event delegation_. This allows the framework
+    to set up a global, shared event listener instead of requiring each view to
+    do it manually. For example, instead of each view registering its own
+    `mousedown` listener on its associated element, Ember sets up a `mousedown`
+    listener on the `body`.
+  
+    If a `mousedown` event occurs, Ember will look at the target of the event and
+    start walking up the DOM node tree, finding corresponding views and invoking
+    their `mouseDown` method as it goes.
+  
+    `Application` has a number of default events that it listens for, as
+    well as a mapping from lowercase events to camel-cased view method names. For
+    example, the `keypress` event causes the `keyPress` method on the view to be
+    called, the `dblclick` event causes `doubleClick` to be called, and so on.
+  
+    If there is a bubbling browser event that Ember does not listen for by
+    default, you can specify custom events and their corresponding view method
+    names by setting the application's `customEvents` property:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    let App = Application.create({
+      customEvents: {
+        // add support for the paste event
+        paste: 'paste'
+      }
+    });
+    ```
+  
+    To prevent Ember from setting up a listener for a default event,
+    specify the event name with a `null` value in the `customEvents`
+    property:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    let App = Application.create({
+      customEvents: {
+        // prevent listeners for mouseenter/mouseleave events
+        mouseenter: null,
+        mouseleave: null
+      }
+    });
+    ```
+  
+    By default, the application sets up these event listeners on the document
+    body. However, in cases where you are embedding an Ember application inside
+    an existing page, you may want it to set up the listeners on an element
+    inside the body.
+  
+    For example, if only events inside a DOM element with the ID of `ember-app`
+    should be delegated, set your application's `rootElement` property:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    let App = Application.create({
+      rootElement: '#ember-app'
+    });
+    ```
+  
+    The `rootElement` can be either a DOM element or a jQuery-compatible selector
+    string. Note that *views appended to the DOM outside the root element will
+    not receive events.* If you specify a custom root element, make sure you only
+    append views inside it!
+  
+    To learn more about the events Ember components use, see
+  
+    [components/handling-events](https://guides.emberjs.com/release/components/handling-events/#toc_event-names).
+  
+    ### Initializers
+  
+    Libraries on top of Ember can add initializers, like so:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    Application.initializer({
+      name: 'api-adapter',
+  
+      initialize: function(application) {
+        application.register('api-adapter:main', ApiAdapter);
+      }
+    });
+    ```
+  
+    Initializers provide an opportunity to access the internal registry, which
+    organizes the different components of an Ember application. Additionally
+    they provide a chance to access the instantiated application. Beyond
+    being used for libraries, initializers are also a great way to organize
+    dependency injection or setup in your own application.
+  
+    ### Routing
+  
+    In addition to creating your application's router, `Application` is
+    also responsible for telling the router when to start routing. Transitions
+    between routes can be logged with the `LOG_TRANSITIONS` flag, and more
+    detailed intra-transition logging can be logged with
+    the `LOG_TRANSITIONS_INTERNAL` flag:
+  
+    ```javascript
+    import Application from '@ember/application';
+  
+    let App = Application.create({
+      LOG_TRANSITIONS: true, // basic logging of successful transitions
+      LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
+    });
+    ```
+  
+    By default, the router will begin trying to translate the current URL into
+    application state once the browser emits the `DOMContentReady` event. If you
+    need to defer routing, you can call the application's `deferReadiness()`
+    method. Once routing can begin, call the `advanceReadiness()` method.
+  
+    If there is any setup required before routing begins, you can implement a
+    `ready()` method on your app that will be invoked immediately before routing
+    begins.
+  
+    @class Application
+    @extends Engine
+    @uses RegistryProxyMixin
+    @public
+  */
+
+  var Application = _engine.default.extend({
+    /**
+      The root DOM element of the Application. This can be specified as an
+      element or a
+      [jQuery-compatible selector string](http://api.jquery.com/category/selectors/).
+       This is the element that will be passed to the Application's,
+      `eventDispatcher`, which sets up the listeners for event delegation. Every

+      and sets up event listeners on the DOM element described by the
+      application's `rootElement` property.
+       See the documentation for `Ember.EventDispatcher` for more information.

+      The DOM events for which the event dispatcher should listen.
+       By default, the application's `Ember.EventDispatcher` listens
+      for a set of standard DOM events, such as `mousedown` and
+      `keyup`, and delegates them to your application's `Ember.View`
+      instances.
+       If you would like additional bubbling events to be delegated to your
+      views, set your `Application`'s `customEvents` property
+      to a hash containing the DOM event name as the key and the
+      corresponding view method name as the value. Setting an event to

+      after all initializers and therefore after all code is loaded and the app is
+      ready.
+       Initializer receives an object which has the following attributes:
+      `name`, `before`, `after`, `initialize`. The only required attribute is
+      `initialize`, all others are optional.
+       * `name` allows you to specify under which name the initializer is registered.
+      This must be a unique name, as trying to register two initializers with the
+      same name will result in an error.
+       ```app/initializer/named-initializer.js
+      import { debug } from '@ember/debug';
+       export function initialize() {
+        debug('Running namedInitializer!');
+      }
+       export default {
+        name: 'named-initializer',
+        initialize
+      };
+      ```
+       * `before` and `after` are used to ensure that this initializer is ran prior
+      or after the one identified by the value. This value can be a single string
+      or an array of strings, referencing the `name` of other initializers.
+       An example of ordering initializers, we create an initializer named `first`:
+       ```app/initializer/first.js
+      import { debug } from '@ember/debug';
+       export function initialize() {
+        debug('First initializer!');
+      }
+       export default {
+        name: 'first',
+        initialize
+      };
+      ```
+       ```bash
+      // DEBUG: First initializer!
+      ```
+       We add another initializer named `second`, specifying that it should run
+      after the initializer named `first`:
+       ```app/initializer/second.js
+      import { debug } from '@ember/debug';
+       export function initialize() {
+        debug('Second initializer!');
+      }
+       export default {
+        name: 'second',
+        after: 'first',
+        initialize
+      };
+      ```
+       ```
+      // DEBUG: First initializer!
+      // DEBUG: Second initializer!
+      ```
+       Afterwards we add a further initializer named `pre`, this time specifying
+      that it should run before the initializer named `first`:
+       ```app/initializer/pre.js
+      import { debug } from '@ember/debug';
+       export function initialize() {
+        debug('Pre initializer!');
+      }
+       export default {
+        name: 'pre',
+        before: 'first',
+        initialize
+      };
+      ```
+       ```bash
+      // DEBUG: Pre initializer!
+      // DEBUG: First initializer!
+      // DEBUG: Second initializer!
+      ```
+       Finally we add an initializer named `post`, specifying it should run after
+      both the `first` and the `second` initializers:
+       ```app/initializer/post.js
+      import { debug } from '@ember/debug';
+       export function initialize() {
+        debug('Post initializer!');
+      }
+       export default {
+        name: 'post',
+        after: ['first', 'second'],
+        initialize
+      };
+      ```
+       ```bash
+      // DEBUG: Pre initializer!
+      // DEBUG: First initializer!
+      // DEBUG: Second initializer!
+      // DEBUG: Post initializer!
+      ```
+       * `initialize` is a callback function that receives one argument,
+        `application`, on which you can operate.
+       Example of using `application` to register an adapter:
+       ```app/initializer/api-adapter.js
+      import ApiAdapter from '../utils/api-adapter';
+       export function initialize(application) {
+        application.register('api-adapter:main', ApiAdapter);
+      }
+       export default {
+        name: 'post',
+        after: ['first', 'second'],
+        initialize
+      };
+      ```
+       @method initializer
+      @param initializer {Object}
+      @public
+    */
+
+    initializer: buildInitializerMethod('initializers', 'initializer'),

+      Instance initializers run after all initializers have run. Because

+      after code has loaded and are not allowed to defer readiness.
+       Instance initializer receives an object which has the following attributes:
+      `name`, `before`, `after`, `initialize`. The only required attribute is
+      `initialize`, all others are optional.
+       * `name` allows you to specify under which name the instanceInitializer is

+       * See Application.initializer for discussion on the usage of before
+      and after.
+       Example instanceInitializer to preload data into the store.
+       ```app/initializer/preload-data.js
+      import $ from 'jquery';

+      ```javascript
+      import { instrument } from '@ember/instrumentation';
+    
+      instrument("render.handlebars", payload, function() {
+        // rendering logic
+      }, binding);
+      ```
+    
+      Event names passed to `instrument` are namespaced

+      can listen for events by whatever level of granularity they

+    
+      In the above example, the event is `render.handlebars`,
+      and the subscriber listened for all events beginning with
+      `render`. It would receive callbacks for events named
+      `render`, `render.handlebars`, `render.container`, or
+      even `render.handlebars.layout`.

+    Allows you to specify which context to call the specified function in while
+    adding the execution of that function to the Ember run loop. This ability
+    makes this method a great way to asynchronously integrate third-party libraries
+    into your Ember application.
+  
+    `bind` takes two main arguments, the desired context and the function to
+    invoke in that context. Any additional arguments will be supplied as arguments
+    to the function that is passed in.
+  
+    Let's use the creation of a TinyMCE component as an example. Currently,
+    TinyMCE provides a setup configuration option we can use to do some processing
+    after the TinyMCE instance is initialized but before it is actually rendered.
+    We can use that setup option to do some additional setup for our component.
+    The component itself could look something like the following:
+  
+    ```app/components/rich-text-editor.js
+    import Component from '@ember/component';
+    import { on } from '@ember/object/evented';
+    import { bind } from '@ember/runloop';
+  
+    export default Component.extend({
+      initializeTinyMCE: on('didInsertElement', function() {
+        tinymce.init({
+          selector: '#' + this.$().prop('id'),
+          setup: bind(this, this.setupEditor)
+        });
+      }),
+  
+      didInsertElement() {
+        tinymce.init({
+          selector: '#' + this.$().prop('id'),
+          setup: bind(this, this.setupEditor)
+        });
+      }
+  
+      setupEditor(editor) {
+        this.set('editor', editor);
+  
+        editor.on('change', function() {
+          console.log('content changed!');
+        });
+      }
+    });
+    ```
+  
+    In this example, we use `bind` to bind the setupEditor method to the
+    context of the RichTextEditor component and to have the invocation of that
+    method be safely handled and executed by the Ember run loop.

+    Schedules an item to run from within a separate run loop, after
+    control has been returned to the system. This is equivalent to calling
+    `later` with a wait time of 1ms.
+  
+    ```javascript
+    import { next } from '@ember/runloop';
+  
+    next(myContext, function() {
+      // code to be executed in the next run loop,
+      // which will be scheduled after the current one
+    });
+    ```
+  
+    Multiple operations scheduled with `next` will coalesce
+    into the same later run loop, along with any other operations
+    scheduled by `later` that expire right around the same
+    time that `next` operations will fire.
+  
+    Note that there are often alternatives to using `next`.
+    For instance, if you'd like to schedule an operation to happen
+    after all DOM element operations have completed within the current
+    run loop, you can make use of the `afterRender` run loop queue (added
+    by the `ember-views` package, along with the preceding `render` queue
+    where all the DOM element operations happen).
+  
+    Example:
+  
+    ```app/components/my-component.js
+    import Component from '@ember/component';
+    import { scheduleOnce } from '@ember/runloop';
+  
+    export Component.extend({
+      didInsertElement() {
+        this._super(...arguments);
+        scheduleOnce('afterRender', this, 'processChildElements');
+      },
+  
+      processChildElements() {
+        // ... do something with component's child component
+        // elements after they've finished rendering, which
+        // can't be done within this component's
+        // `didInsertElement` hook because that gets run
+        // before the child elements have been added to the DOM.
+      }
+    });
+    ```
+  
+    One benefit of the above approach compared to using `next` is
+    that you will be able to perform DOM/CSS operations before unprocessed
+    elements are rendered to the screen, which may prevent flickering or
+    other artifacts caused by delaying processing until after rendering.
+  
+    The other major benefit to the above approach is that `next`
+    introduces an element of non-determinism, which can make things much
+    harder to test, due to its reliance on `setTimeout`; it's much harder
+    to guarantee the order of scheduled operations when they are scheduled
+    outside of the current run loop, i.e. with `next`.

+    
+      ```handlebars
+      <div>{{format-currency cents currency="$"}}</div>
+      ```
+    
+      Additionally a helper can be called as a nested helper (sometimes called a
+      subexpression). In this example, the computed value of a helper is passed
+      to a component named `show-money`:
+    
+      ```handlebars
+      {{show-money amount=(format-currency cents currency="$")}}
+      ```
+    
+      Helpers defined using a class must provide a `compute` function. For example:

+      ```app/helpers/format-currency.js
+      import Helper from '@ember/component/helper';

+        }
+      });
+      ```
+    
+      Each time the input to a helper changes, the `compute` function will be
+      called again.
+    
+      As instances, these helpers also have access to the container and will accept
+      injected dependencies.
+    
+      Additionally, class helpers can call `recompute` to force a new computation.

+        }
+        // ember doesn't do observing with functions
+        if (typeof value === 'function') {
+            return new UnboundReference(value);
+        }

+    /**
+      A `Component` is a view that is completely
+      isolated. Properties accessed in its templates go
+      to the view object and actions are targeted at
+      the view object. There is no access to the
+      surrounding context or outer controller; all
+      contextual information must be passed in.
+    
+      The easiest way to create a `Component` is via
+      a template. If you name a template
+      `app/components/my-foo.hbs`, you will be able to use
+      `{{my-foo}}` in other templates, which will make
+      an instance of the isolated component.
+    
+      ```app/components/my-foo.hbs
+      {{person-profile person=currentUser}}
+      ```
+    
+      ```app/components/person-profile.hbs
+      <h1>{{person.title}}</h1>
+      <img src={{person.avatar}}>
+      <p class='signature'>{{person.signature}}</p>
+      ```
+    
+      You can use `yield` inside a template to
+      include the **contents** of any block attached to
+      the component. The block will be executed in the
+      context of the surrounding context or outer controller:
+    
+      ```handlebars
+      {{#person-profile person=currentUser}}
+        <p>Admin mode</p>
+        {{! Executed in the controller's context. }}
+      {{/person-profile}}
+      ```
+    
+      ```app/components/person-profile.hbs
+      <h1>{{person.title}}</h1>
+      {{! Executed in the component's context. }}
+      {{yield}} {{! block contents }}
+      ```
+    
+      If you want to customize the component, in order to
+      handle events or actions, you implement a subclass
+      of `Component` named after the name of the
+      component.
+    
+      For example, you could implement the action
+      `hello` for the `person-profile` component:
+    
+      ```app/components/person-profile.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        actions: {
+          hello(name) {
+            console.log("Hello", name);
+          }
+        }
+      });
+      ```
+    
+      And then use it in the component's template:
+    
+      ```app/templates/components/person-profile.hbs
+      <h1>{{person.title}}</h1>
+      {{yield}} <!-- block contents -->
+      <button {{action 'hello' person.name}}>
+        Say Hello to {{person.name}}
+      </button>
+      ```
+    
+      Components must have a `-` in their name to avoid
+      conflicts with built-in controls that wrap HTML
+      elements. This is consistent with the same
+      requirement in web components.
+    
+      ## HTML Tag
+    
+      The default HTML tag name used for a component's DOM representation is `div`.
+      This can be customized by setting the `tagName` property.
+      The following component class:
+    
+      ```app/components/emphasized-paragraph.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        tagName: 'em'
+      });
+      ```
+    
+      Would result in instances with the following HTML:
+    
+      ```html
+      <em id="ember1" class="ember-view"></em>
+      ```
+    
+      ## HTML `class` Attribute
+    
+      The HTML `class` attribute of a component's tag can be set by providing a
+      `classNames` property that is set to an array of strings:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        classNames: ['my-class', 'my-other-class']
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view my-class my-other-class"></div>
+      ```
+    
+      `class` attribute values can also be set by providing a `classNameBindings`
+      property set to an array of properties names for the component. The return value
+      of these properties will be added as part of the value for the components's `class`
+      attribute. These properties can be computed properties:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+      import { computed } from '@ember/object';
+    
+      export default Component.extend({
+        classNameBindings: ['propertyA', 'propertyB'],
+    
+        propertyA: 'from-a',
+        propertyB: computed(function() {
+          if (someLogic) { return 'from-b'; }
+        })
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view from-a from-b"></div>
+      ```
+    
+      If the value of a class name binding returns a boolean the property name
+      itself will be used as the class name if the property is true.
+      The class name will not be added if the value is `false` or `undefined`.
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        classNameBindings: ['hovered'],
+    
+        hovered: true
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view hovered"></div>
+      ```
+    
+      When using boolean class name bindings you can supply a string value other
+      than the property name for use as the `class` HTML attribute by appending the
+      preferred value after a ":" character when defining the binding:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        classNameBindings: ['awesome:so-very-cool'],
+    
+        awesome: true
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view so-very-cool"></div>
+      ```
+    
+      Boolean value class name bindings whose property names are in a
+      camelCase-style format will be converted to a dasherized format:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        classNameBindings: ['isUrgent'],
+    
+        isUrgent: true
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view is-urgent"></div>
+      ```
+    
+      Class name bindings can also refer to object values that are found by
+      traversing a path relative to the component itself:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+      import EmberObject from '@ember/object';
+    
+      export default Component.extend({
+        classNameBindings: ['messages.empty'],
+    
+        messages: EmberObject.create({
+          empty: true
+        })
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view empty"></div>
+      ```
+    
+      If you want to add a class name for a property which evaluates to true and
+      and a different class name if it evaluates to false, you can pass a binding
+      like this:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        classNameBindings: ['isEnabled:enabled:disabled'],
+        isEnabled: true
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view enabled"></div>
+      ```
+    
+      When isEnabled is `false`, the resulting HTML representation looks like
+      this:
+    
+      ```html
+      <div id="ember1" class="ember-view disabled"></div>
+      ```
+    
+      This syntax offers the convenience to add a class if a property is `false`:
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
+      export default Component.extend({
+        classNameBindings: ['isEnabled::disabled'],
+        isEnabled: true
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view"></div>
+      ```
+    
+      When the `isEnabled` property on the component is set to `false`, it will result
+      in component instances with an HTML representation of:
+    
+      ```html
+      <div id="ember1" class="ember-view disabled"></div>
+      ```
+    
+      Updates to the value of a class name binding will result in automatic
+      update of the  HTML `class` attribute in the component's rendered HTML
+      representation. If the value becomes `false` or `undefined` the class name
+      will be removed.
+      Both `classNames` and `classNameBindings` are concatenated properties. See
+      [EmberObject](/api/ember/release/classes/EmberObject) documentation for more
+      information about concatenated properties.
+    
+      ## HTML Attributes
+    
+      The HTML attribute section of a component's tag can be set by providing an
+      `attributeBindings` property set to an array of property names on the component.
+      The return value of these properties will be used as the value of the component's
+      HTML associated attribute:
+    
+      ```app/components/my-anchor.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        tagName: 'a',
+        attributeBindings: ['href'],
+    
+        href: 'http://google.com'
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <a id="ember1" class="ember-view" href="http://google.com"></a>
+      ```
+    
+      One property can be mapped on to another by placing a ":" between
+      the source property and the destination property:
+    
+      ```app/components/my-anchor.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        tagName: 'a',
+        attributeBindings: ['url:href'],
+    
+        url: 'http://google.com'
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <a id="ember1" class="ember-view" href="http://google.com"></a>
+      ```
+    
+      Namespaced attributes (e.g. `xlink:href`) are supported, but have to be
+      mapped, since `:` is not a valid character for properties in Javascript:
+    
+      ```app/components/my-use.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        tagName: 'use',
+        attributeBindings: ['xlinkHref:xlink:href'],
+    
+        xlinkHref: '#triangle'
+      });
+      ```
+    
+      Will result in component instances with an HTML representation of:
+    
+      ```html
+      <use xlink:href="#triangle"></use>
+      ```
+    
+      If the return value of an `attributeBindings` monitored property is a boolean
+      the attribute will be present or absent depending on the value:
+    
+      ```app/components/my-text-input.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        tagName: 'input',
+        attributeBindings: ['disabled'],
+    
+        disabled: false
+      });
+      ```
+    
+      Will result in a component instance with an HTML representation of:
+    
+      ```html
+      <input id="ember1" class="ember-view" />
+      ```
+    
+      `attributeBindings` can refer to computed properties:
+    
+      ```app/components/my-text-input.js
+      import Component from '@ember/component';
+      import { computed } from '@ember/object';
+    
+      export default Component.extend({
+        tagName: 'input',
+        attributeBindings: ['disabled'],
+    
+        disabled: computed(function() {
+          if (someLogic) {
+            return true;
+          } else {
+            return false;
+          }
+        })
+      });
+      ```
+    
+      To prevent setting an attribute altogether, use `null` or `undefined` as the
+      return value of the `attributeBindings` monitored property:
+    
+      ```app/components/my-text-input.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        tagName: 'form',
+        attributeBindings: ['novalidate'],
+        novalidate: null
+      });
+      ```
+    
+      Updates to the property of an attribute binding will result in automatic
+      update of the  HTML attribute in the component's rendered HTML representation.
+      `attributeBindings` is a concatenated property. See [EmberObject](/api/ember/release/classes/EmberObject)
+      documentation for more information about concatenated properties.
+    
+      ## Layouts
+    
+      See [Ember.Templates.helpers.yield](/api/ember/release/classes/Ember.Templates.helpers/methods/yield?anchor=yield)
+      for more information.
+    
+      Layout can be used to wrap content in a component. In addition
+      to wrapping content in a Component's template, you can also use
+      the public layout API in your Component JavaScript.
+    
+      ```app/templates/components/person-profile.hbs
+        <h1>Person's Title</h1>
+        <div class='details'>{{yield}}</div>
+      ```
+    
+      ```app/components/person-profile.js
+        import Component from '@ember/component';
+        import layout from '../templates/components/person-profile';
+    
+        export default Component.extend({
+          layout
+        });
+      ```
+    
+      The above will result in the following HTML output:
+    
+      ```html
+        <h1>Person's Title</h1>
+        <div class="details">
+          <h2>Chief Basket Weaver</h2>
+          <h3>Fisherman Industries</h3>
+        </div>
+      ```
+    
+      ## Responding to Browser Events
+    
+      Components can respond to user-initiated events in one of three ways: method
+      implementation, through an event manager, and through `{{action}}` helper use
+      in their template or layout.
+    
+      ### Method Implementation
+    
+      Components can respond to user-initiated events by implementing a method that
+      matches the event name. A `jQuery.Event` object will be passed as the
+      argument to this method.
+    
+      ```app/components/my-widget.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        click(event) {
+          // will be called when an instance's
+          // rendered element is clicked
+        }
+      });
+      ```
+    
+      ### `{{action}}` Helper
+    
+      See [Ember.Templates.helpers.action](/api/ember/release/classes/Ember.Templates.helpers/methods/yield?anchor=yield).
+    
+      ### Event Names
+    
+      All of the event handling approaches described above respond to the same set
+      of events. The names of the built-in events are listed below. (The hash of
+      built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
+      can be registered by using `Application.customEvents`.
+    
+      Touch events:
+    
+      * `touchStart`
+      * `touchMove`
+      * `touchEnd`
+      * `touchCancel`
+    
+      Keyboard events:
+    
+      * `keyDown`
+      * `keyUp`
+      * `keyPress`
+    
+      Mouse events:
+    
+      * `mouseDown`
+      * `mouseUp`
+      * `contextMenu`
+      * `click`
+      * `doubleClick`
+      * `mouseMove`
+      * `focusIn`
+      * `focusOut`
+      * `mouseEnter`
+      * `mouseLeave`
+    
+      Form events:
+    
+      * `submit`
+      * `change`
+      * `focusIn`
+      * `focusOut`
+      * `input`
+    
+      HTML5 drag and drop events:
+    
+      * `dragStart`
+      * `drag`
+      * `dragEnter`
+      * `dragLeave`
+      * `dragOver`
+      * `dragEnd`
+      * `drop`

+      The attributes of `{{textarea}}` match those of the native HTML tags as
+      closely as possible.
+    
+      The following HTML attributes can be set:
+    
+        * `value`
+        * `name`
+        * `rows`
+        * `cols`

+        * `selectionStart`
+        * `autocomplete`
+        * `selectionDirection`
+        * `wrap`
+        * `readonly`
+        * `autofocus`
+        * `form`
+        * `spellcheck`
+        * `required`
+    
+      When set to a quoted string, these value will be directly applied to the HTML
+      element. When left unquoted, these values will be bound to a property on the
+      template's current rendering context (most typically a controller instance).
+    
+      Unbound:
+    
+      ```handlebars
+      {{textarea value="Lots of static text that ISN'T bound"}}
+      ```
+    
+      Would result in the following HTML:
+    
+      ```html
+      <textarea class="ember-text-area">
+        Lots of static text that ISN'T bound
+      </textarea>
+      ```
+    
+      Bound:
+    
+      In the following example, the `writtenWords` property on the application
+      Controller will be updated live as the user types 'Lots of text that IS
+      bound' into the text area of their browser's window.
+    
+      ```app/controllers/application.js
+      import Controller from '@ember/controller';
+    
+      export default Controller.extend({
+        writtenWords: "Lots of text that IS bound"
+      });
+      ```
+    
+      ```handlebars
+      {{textarea value=writtenWords}}
+      ```
+    
+      Would result in the following HTML:
+    
+      ```html
+      <textarea class="ember-text-area">
+        Lots of text that IS bound
+      </textarea>
+      ```
+    
+      If you wanted a one way binding between the text area and a div tag
+      somewhere else on your screen, you could use `oneWay`:
+    
+      ```app/controllers/application.js
+      import Controller from '@ember/controller';
+      import { oneWay } from '@ember/object/computed';
+    
+      export default Controller.extend({
+        writtenWords: "Lots of text that IS bound",
+    
+        outputWrittenWords: oneWay("writtenWords")
+      });
+      ```
+    
+      ```handlebars
+      {{textarea value=writtenWords}}
+      <div>
+        {{outputWrittenWords}}
+      </div>
+      ```
+    
+      Would result in the following HTML:
+    
+      ```html
+      <textarea class="ember-text-area">
+        Lots of text that IS bound
+      </textarea>
+      <-- the following div will be updated in real time as you type -->
+      <div>
+        Lots of text that IS bound
+      </div>
+      ```
+    
+      Finally, this example really shows the power and ease of Ember when two
+      properties are bound to eachother via `alias`. Type into
+      either text area box and they'll both stay in sync. Note that
+      `alias` costs more in terms of performance, so only use it when
+      your really binding in both directions:
+    
+      ```app/controllers/application.js
+      import Controller from '@ember/controller';
+      import { alias } from '@ember/object/computed';
+    
+      export default Controller.extend({
+        writtenWords: "Lots of text that IS bound",
+    
+        twoWayWrittenWords: alias("writtenWords")
+      });
+      ```
+    
+      ```handlebars
+      {{textarea value=writtenWords}}
+      {{textarea value=twoWayWrittenWords}}
+      ```
+    
+      ```html
+      <textarea id="ember1" class="ember-text-area">
+        Lots of text that IS bound
+      </textarea>
+      <-- both updated in real time -->
+      <textarea id="ember2" class="ember-text-area">
+        Lots of text that IS bound
+      </textarea>
+      ```
+    
+      ### Actions
+    
+      The helper can send multiple actions based on user events.
+      The action property defines the action which is send when
+      the user presses the return key.
+    
+      ```handlebars
+      {{input action="submit"}}
+      ```
+    
+      The helper allows some user events to send actions.
+    
+      * `enter`
+      * `insert-newline`
+      * `escape-press`
+      * `focus-in`
+      * `focus-out`
+      * `key-press`
+    
+      For example, if you desire an action to be sent when the input is blurred,
+      you only need to setup the action name to the event name property.
+    
+      ```handlebars
+      {{textarea focus-out="alertMessage"}}
+      ```
+    
+      See more about [Text Support Actions](/api/ember/release/classes/TextArea)
+    
+      ### Extension
+    
+      Internally, `{{textarea}}` creates an instance of `TextArea`, passing
+      arguments from the helper to `TextArea`'s `create` method. You can
+      extend the capabilities of text areas in your application by reopening this
+      class. For example, if you are building a Bootstrap project where `data-*`
+      attributes are used, you can globally add support for a `data-*` attribute
+      on all `{{textarea}}`s' in your app by reopening `TextArea` or
+      `TextSupport` and adding it to the `attributeBindings` concatenated
+      property:
+    
+      ```javascript
+      import TextArea from '@ember/component/text-area';
+    
+      TextArea.reopen({
+        attributeBindings: ['data-error']
+      });
+      ```
+    
+      Keep in mind when writing `TextArea` subclasses that `TextArea`
+      itself extends `Component`. Expect isolated component semantics, not
+      legacy 1.x view semantics (like `controller` being present).
+

+      The `{{#each}}` helper loops over elements in a collection. It is an extension
+      of the base Handlebars `{{#each}}` helper.
+      The default behavior of `{{#each}}` is to yield its inner block once for every
+      item in an array passing the item as the first block parameter.
+    
+      ```javascript
+      var developers = [{ name: 'Yehuda' },{ name: 'Tom' }, { name: 'Paul' }];
+      ```
+    
+      ```handlebars
+      {{#each developers key="name" as |person|}}
+        {{person.name}}
+        {{! `this` is whatever it was outside the #each }}
+      {{/each}}
+      ```
+    
+      The same rules apply to arrays of primitives.
+    
+      ```javascript
+      var developerNames = ['Yehuda', 'Tom', 'Paul']
+      ```
+    
+      ```handlebars
+      {{#each developerNames key="@index" as |name|}}
+        {{name}}
+      {{/each}}
+      ```
+    
+      During iteration, the index of each item in the array is provided as a second block parameter.
+    
+      ```handlebars
+      <ul>
+        {{#each people as |person index|}}
+          <li>Hello, {{person.name}}! You're number {{index}} in line</li>
+        {{/each}}
+      </ul>
+      ```
+    
+      ### Specifying Keys
+    
+      The `key` option is used to tell Ember how to determine if the array being
+      iterated over with `{{#each}}` has changed between renders. By helping Ember
+      detect that some elements in the array are the same, DOM elements can be
+      re-used, significantly improving rendering speed.
+    
+      For example, here's the `{{#each}}` helper with its `key` set to `id`:
+    
+      ```handlebars
+      {{#each model key="id" as |item|}}
+      {{/each}}
+      ```
+    
+      When this `{{#each}}` re-renders, Ember will match up the previously rendered
+      items (and reorder the generated DOM elements) based on each item's `id`
+      property.
+      By default the item's own reference is used.
+    
+      ### {{else}} condition
+    
+      `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
+      if the collection is empty.
+    
+      ```handlebars
+      {{#each developers as |person|}}
+        {{person.name}}
+      {{else}}
+        <p>Sorry, nobody is available for this task.</p>
+      {{/each}}
+      ```

+      The `{{each-in}}` helper loops over properties on an object.

+      {
+        "name": "Shelly Sails",
+        "age": 42
+      }
+      ```
+    
+      This template would display all properties on the `user`

+      <ul>

+    /**
+      The `{{action}}` helper provides a way to pass triggers for behavior (usually
+      just a function) between components, and into components from controllers.
+    
+      ### Passing functions with the action helper
+    
+      There are three contexts an action helper can be used in. The first two
+      contexts to discuss are attribute context, and Handlebars value context.
+    
+      ```handlebars
+      {{! An example of attribute context }}
+      <div onclick={{action "save"}}></div>
+      {{! Examples of Handlebars value context }}
+      {{input on-input=(action "save")}}
+      {{yield (action "refreshData") andAnotherParam}}
+      ```
+    
+      In these contexts,
+      the helper is called a "closure action" helper. Its behavior is simple:
+      If passed a function name, read that function off the `actions` property
+      of the current context. Once that function is read, or immediately if a function was
+      passed, create a closure over that function and any arguments.
+      The resulting value of an action helper used this way is simply a function.
+    
+      For example, in the attribute context:
+    
+      ```handlebars
+      {{! An example of attribute context }}
+      <div onclick={{action "save"}}></div>
+      ```
+    
+      The resulting template render logic would be:
+    
+      ```js
+      var div = document.createElement('div');
+      var actionFunction = (function(context){
+        return function() {
+          return context.actions.save.apply(context, arguments);
+        };
+      })(context);
+      div.onclick = actionFunction;
+      ```
+    
+      Thus when the div is clicked, the action on that context is called.
+      Because the `actionFunction` is just a function, closure actions can be
+      passed between components and still execute in the correct context.
+    
+      Here is an example action handler on a component:
+    
+      ```app/components/my-component.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        actions: {
+          save() {
+            this.get('model').save();
+          }
+        }
+      });
+      ```
+    
+      Actions are always looked up on the `actions` property of the current context.
+      This avoids collisions in the naming of common actions, such as `destroy`.
+      Two options can be passed to the `action` helper when it is used in this way.
+    
+      * `target=someProperty` will look to `someProperty` instead of the current
+        context for the `actions` hash. This can be useful when targeting a
+        service for actions.
+      * `value="target.value"` will read the path `target.value` off the first
+        argument to the action when it is called and rewrite the first argument
+        to be that value. This is useful when attaching actions to event listeners.
+    
+      ### Invoking an action
+    
+      Closure actions curry both their scope and any arguments. When invoked, any
+      additional arguments are added to the already curried list.
+      Actions should be invoked using the [sendAction](/api/ember/release/classes/Component/methods/sendAction?anchor=sendAction)
+      method. The first argument to `sendAction` is the action to be called, and
+      additional arguments are passed to the action function. This has interesting
+      properties combined with currying of arguments. For example:
+    
+      ```app/components/my-component.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        actions: {
+          // Usage {{input on-input=(action (action 'setName' model) value="target.value")}}
+          setName(model, name) {
+            model.set('name', name);
+          }
+        }
+      });
+      ```
+    
+      The first argument (`model`) was curried over, and the run-time argument (`event`)
+      becomes a second argument. Action calls can be nested this way because each simply
+      returns a function. Any function can be passed to the `{{action}}` helper, including
+      other actions.
+    
+      Actions invoked with `sendAction` have the same currying behavior as demonstrated
+      with `on-input` above. For example:
+    
+      ```app/components/my-input.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        actions: {
+          setName(model, name) {
+            model.set('name', name);
+          }
+        }
+      });
+      ```
+    
+      ```handlebars
+      {{my-input submit=(action 'setName' model)}}
+      ```
+    
+      ```app/components/my-component.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        click() {
+          // Note that model is not passed, it was curried in the template
+          this.sendAction('submit', 'bob');
+        }
+      });
+      ```
+    
+      ### Attaching actions to DOM elements
+    
+      The third context of the `{{action}}` helper can be called "element space".
+      For example:
+    
+      ```handlebars
+      {{! An example of element space }}
+      <div {{action "save"}}></div>
+      ```
+    
+      Used this way, the `{{action}}` helper provides a useful shortcut for
+      registering an HTML element in a template for a single DOM event and
+      forwarding that interaction to the template's context (controller or component).
+      If the context of a template is a controller, actions used this way will
+      bubble to routes when the controller does not implement the specified action.
+      Once an action hits a route, it will bubble through the route hierarchy.
+    
+      ### Event Propagation
+    
+      `{{action}}` helpers called in element space can control event bubbling. Note
+      that the closure style actions cannot.
+    
+      Events triggered through the action helper will automatically have
+      `.preventDefault()` called on them. You do not need to do so in your event
+      handlers. If you need to allow event propagation (to handle file inputs for
+      example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
+    
+      ```handlebars
+      <div {{action "sayHello" preventDefault=false}}>
+        <input type="file" />
+        <input type="checkbox" />
+      </div>
+      ```
+    
+      To disable bubbling, pass `bubbles=false` to the helper:
+    
+      ```handlebars
+      <button {{action 'edit' post bubbles=false}}>Edit</button>
+      ```
+    
+      To disable bubbling with closure style actions you must create your own
+      wrapper helper that makes use of `event.stopPropagation()`:
+    
+      ```handlebars
+      <div onclick={{disable-bubbling (action "sayHello")}}>Hello</div>
+      ```
+    
+      ```app/helpers/disable-bubbling.js
+      import { helper } from '@ember/component/helper';
+    
+      export function disableBubbling([action]) {
+        return function(event) {
+          event.stopPropagation();
+          return action(event);
+        };
+      }
+      export default helper(disableBubbling);
+      ```
+    
+      If you need the default handler to trigger you should either register your
+      own event handler, or use event methods on your view class. See
+      ["Responding to Browser Events"](/api/ember/release/classes/Component)
+      in the documentation for `Component` for more information.
+    
+      ### Specifying DOM event type
+    
+      `{{action}}` helpers called in element space can specify an event type.
+      By default the `{{action}}` helper registers for DOM `click` events. You can
+      supply an `on` option to the helper to specify a different DOM event name:
+    
+      ```handlebars
+      <div {{action "anActionName" on="doubleClick"}}>
+        click me
+      </div>
+      ```
+    
+      See ["Event Names"](/api/ember/release/classes/Component) for a list of
+      acceptable DOM event names.
+    
+      ### Specifying whitelisted modifier keys
+    
+      `{{action}}` helpers called in element space can specify modifier keys.
+      By default the `{{action}}` helper will ignore click events with pressed modifier
+      keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
+    
+      ```handlebars
+      <div {{action "anActionName" allowedKeys="alt"}}>
+        click me
+      </div>
+      ```
+    
+      This way the action will fire when clicking with the alt key pressed down.
+      Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
+    
+      ```handlebars
+      <div {{action "anActionName" allowedKeys="any"}}>
+        click me with any key pressed
+      </div>
+      ```
+    
+      ### Specifying a Target
+    
+      A `target` option can be provided to the helper to change
+      which object will receive the method call. This option must be a path
+      to an object, accessible in the current context:
+    
+      ```app/templates/application.hbs
+      <div {{action "anActionName" target=someService}}>
+        click me
+      </div>
+      ```
+    
+      ```app/controllers/application.js
+      import Controller from '@ember/controller';
+      import { inject as service } from '@ember/service';
+    
+      export default Controller.extend({
+        someService: service()
+      });
+      ```

+      The `if` helper allows you to conditionally render one of two branches,
+      depending on the "truthiness" of a property.
+      For example the following values are all falsey: `false`, `undefined`, `null`, `""`, `0`, `NaN` or an empty array.
+    
+      This helper has two forms, block and inline.
+    
+      ## Block form
+    
+      You can use the block form of `if` to conditionally render a section of the template.
+    
+      To use it, pass the conditional value to the `if` helper,
+      using the block form to wrap the section of template you want to conditionally render.
+      Like so:
+    
+      ```handlebars
+      {{! will not render if foo is falsey}}
+      {{#if foo}}
+        Welcome to the {{foo.bar}}
+      {{/if}}
+      ```
+    
+      You can also specify a template to show if the property is falsey by using
+      the `else` helper.
+    
+      ```handlebars
+      {{! is it raining outside?}}
+      {{#if isRaining}}
+        Yes, grab an umbrella!
+      {{else}}
+        No, it's lovely outside!
+      {{/if}}
+      ```
+    
+      You are also able to combine `else` and `if` helpers to create more complex
+      conditional logic.
+    
+      ```handlebars
+      {{#if isMorning}}
+        Good morning
+      {{else if isAfternoon}}
+        Good afternoon
+      {{else}}
+        Good night
+      {{/if}}
+      ```
+    
+      ## Inline form
+    
+      The inline `if` helper conditionally renders a single property or string.
+    
+      In this form, the `if` helper receives three arguments, the conditional value,
+      the value to render when truthy, and the value to render when falsey.
+    
+      For example, if `useLongGreeting` is truthy, the following:
+    
+      ```handlebars
+      {{if useLongGreeting "Hello" "Hi"}} Alex
+      ```
+    
+      Will render:
+    
+      ```html
+      Hello Alex
+      ```
+    
+      ### Nested `if`
+    
+      You can use the `if` helper inside another helper as a nested helper:
+    
+      ```handlebars
+      {{some-component height=(if isBig "100" "10")}}
+      ```
+    
+      One detail to keep in mind is that both branches of the `if` helper will be evaluated,
+      so if you have `{{if condition "foo" (expensive-operation "bar")`,
+      `expensive-operation` will always calculate.

+

+      The `mut` helper lets you __clearly specify__ that a child `Component` can update the
+      (mutable) value passed to it, which will __change the value of the parent component__.
+    
+      To specify that a parameter is mutable, when invoking the child `Component`:
+    
+      ```handlebars
+      {{my-child childClickCount=(mut totalClicks)}}
+      ```
+    
+      The child `Component` can then modify the parent's value just by modifying its own
+      property:
+    
+      ```javascript
+      // my-child.js
+      export default Component.extend({
+        click() {
+          this.incrementProperty('childClickCount');
+        }
+      });
+      ```
+    
+      Note that for curly components (`{{my-component}}`) the bindings are already mutable,
+      making the `mut` unnecessary.
+    
+      Additionally, the `mut` helper can be combined with the `action` helper to
+      mutate a value. For example:
+    
+      ```handlebars
+      {{my-child childClickCount=totalClicks click-count-change=(action (mut totalClicks))}}
+      ```
+    
+      The child `Component` would invoke the action with the new click value:
+    
+      ```javascript
+      // my-child.js
+      export default Component.extend({
+        click() {
+          this.get('click-count-change')(this.get('childClickCount') + 1);
+        }
+      });
+      ```
+    
+      The `mut` helper changes the `totalClicks` value to what was provided as the action argument.
+    
+      The `mut` helper, when used with `action`, will return a function that
+      sets the value passed to `mut` to its first argument. This works like any other
+      closure action and interacts with the other features `action` provides.
+      As an example, we can create a button that increments a value passing the value
+      directly to the `action`:
+    
+      ```handlebars
+      {{! inc helper is not provided by Ember }}
+      <button onclick={{action (mut count) (inc count)}}>
+        Increment count
+      </button>
+      ```
+    
+      You can also use the `value` option:
+    
+      ```handlebars
+      <input value={{name}} oninput={{action (mut name) value="target.value"}}>
+      ```
+

+    /**
+      The `readonly` helper let's you specify that a binding is one-way only,
+      instead of two-way.
+      When you pass a `readonly` binding from an outer context (e.g. parent component),
+      to to an inner context (e.g. child component), you are saying that changing that
+      property in the inner context does not change the value in the outer context.
+    
+      To specify that a binding is read-only, when invoking the child `Component`:
+    
+      ```app/components/my-parent.js
+      export default Component.extend({
+        totalClicks: 3
+      });
+      ```
+    
+      ```app/templates/components/my-parent.hbs
+      {{log totalClicks}} // -> 3
+      {{my-child childClickCount=(readonly totalClicks)}}
+      ```
+    
+      Now, when you update `childClickCount`:
+    
+      ```app/components/my-child.js
+      export default Component.extend({
+        click() {
+          this.incrementProperty('childClickCount');
+        }
+      });
+      ```
+    
+      The value updates in the child component, but not the parent component:
+    
+      ```app/templates/components/my-child.hbs
+      {{log childClickCount}} //-> 4
+      ```
+    
+      ```app/templates/components/my-parent.hbs
+      {{log totalClicks}} //-> 3
+      {{my-child childClickCount=(readonly totalClicks)}}
+      ```
+    
+      ### Objects and Arrays
+    
+      When passing a property that is a complex object (e.g. object, array) instead of a primitive object (e.g. number, string),
+      only the reference to the object is protected using the readonly helper.
+      This means that you can change properties of the object both on the parent component, as well as the child component.
+      The `readonly` binding behaves similar to the `const` keyword in JavaScript.
+    
+      Let's look at an example:
+    
+      First let's set up the parent component:
+    
+      ```app/components/my-parent.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        clicks: null,
+    
+        init() {
+          this._super(...arguments);
+          this.set('clicks', { total: 3 });
+        }
+      });
+      ```
+    
+      ```app/templates/components/my-parent.hbs
+      {{log clicks.total}} //-> 3
+      {{my-child childClicks=(readonly clicks)}}
+      ```
+    
+      Now, if you update the `total` property of `childClicks`:
+    
+      ```app/components/my-child.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        click() {
+          this.get('clicks').incrementProperty('total');
+        }
+      });
+      ```
+    
+      You will see the following happen:
+    
+      ```app/templates/components/my-parent.hbs
+      {{log clicks.total}} //-> 4
+      {{my-child childClicks=(readonly clicks)}}
+      ```
+    
+      ```app/templates/components/my-child.hbs
+      {{log childClicks.total}} //-> 4
+      ```
+    
+      @method readonly
+      @param {Object} [attr] the read-only attribute.
+      @for Ember.Templates.helpers
+      @private
+    */
+    function readonly(_vm, args) {
+        var ref = unMut(args.positional.at(0));
+        return new ReadonlyReference(ref);
+    }
+
+    /**
+    @module ember
+    */
+    /**
+      The `{{unbound}}` helper disconnects the one-way binding of a property,
+      essentially freezing its value at the moment of rendering. For example,
+      in this example the display of the variable `name` will not change even
+      if it is set with a new value:
+    
+      ```handlebars
+      {{unbound name}}
+      ```
+    
+      Like any helper, the `unbound` helper can accept a nested helper expression.
+      This allows for custom helpers to be rendered unbound:
+    
+      ```handlebars
+      {{unbound (some-custom-helper)}}
+      {{unbound (capitalize name)}}
+      {{! You can use any helper, including unbound, in a nested expression }}
+      {{capitalize (unbound name)}}
+      ```
+    
+      The `unbound` helper only accepts a single argument, and it return an
+      unbound value.

+      The `{{input}}` helper lets you create an HTML `<input />` component.
+      It causes an `TextField` component to be rendered.  For more info,
+      see the [TextField](/api/ember/release/classes/TextField) docs and
+      the [templates guide](https://guides.emberjs.com/release/templates/input-helpers/).
+    
+      ```handlebars
+      {{input value="987"}}
+      ```
+    
+      renders as:
+    
+      ```HTML
+      <input type="text" value="987" />
+      ```
+    
+      ### Text field
+    
+      If no `type` option is specified, a default of type 'text' is used.
+      Many of the standard HTML attributes may be passed to this helper.
+      <table>
+        <tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>
+        <tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>
+        <tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>
+        <tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>
+        <tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>
+        <tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>
+        <tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>
+        <tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>
+        <tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>
+        <tr><td>`selectionDirection`</td><td>`spellcheck`</td><td>&nbsp;</td></tr>
+      </table>
+      When set to a quoted string, these values will be directly applied to the HTML
+      element. When left unquoted, these values will be bound to a property on the
+      template's current rendering context (most typically a controller instance).
+      A very common use of this helper is to bind the `value` of an input to an Object's attribute:
+    
+      ```handlebars
+      Search:
+      {{input value=searchWord}}
+      ```
+    
+      In this example, the initial value in the `<input />` will be set to the value of `searchWord`.
+      If the user changes the text, the value of `searchWord` will also be updated.
+    
+      ### Actions
+    
+      The helper can send multiple actions based on user events.
+      The action property defines the action which is sent when
+      the user presses the return key.
+    
+      ```handlebars
+      {{input action="submit"}}
+      ```
+    
+      The helper allows some user events to send actions.
+    
+      * `enter`
+      * `insert-newline`
+      * `escape-press`
+      * `focus-in`
+      * `focus-out`
+      * `key-press`
+      * `key-up`
+    
+      For example, if you desire an action to be sent when the input is blurred,
+      you only need to setup the action name to the event name property.
+    
+      ```handlebars
+      {{input focus-out="alertMessage"}}
+      ```
+      See more about [Text Support Actions](/api/ember/release/classes/TextField)
+    
+      ### Extending `TextField`
+    
+      Internally, `{{input type="text"}}` creates an instance of `TextField`, passing
+      arguments from the helper to `TextField`'s `create` method. You can extend the
+      capabilities of text inputs in your applications by reopening this class. For example,
+      if you are building a Bootstrap project where `data-*` attributes are used, you
+      can add one to the `TextField`'s `attributeBindings` property:
+    
+      ```javascript
+      import TextField from '@ember/component/text-field';
+      TextField.reopen({
+        attributeBindings: ['data-error']
+      });
+      ```
+    
+      Keep in mind when writing `TextField` subclasses that `TextField`
+      itself extends `Component`. Expect isolated component semantics, not
+      legacy 1.x view semantics (like `controller` being present).
+      See more about [Ember components](/api/ember/release/classes/Component)
+    
+      ### Checkbox
+    
+      Checkboxes are special forms of the `{{input}}` helper.  To create a `<checkbox />`:
+    
+      ```handlebars
+      Emberize Everything:
+      {{input type="checkbox" name="isEmberized" checked=isEmberized}}
+      ```
+    
+      This will bind checked state of this checkbox to the value of `isEmberized`  -- if either one changes,
+      it will be reflected in the other.
+    
+      The following HTML attributes can be set via the helper:
+    
+      * `checked`
+      * `disabled`
+      * `tabindex`
+      * `indeterminate`
+      * `name`
+      * `autofocus`
+      * `form`
+    
+      ### Extending `Checkbox`
+    
+      Internally, `{{input type="checkbox"}}` creates an instance of `Checkbox`, passing
+      arguments from the helper to `Checkbox`'s `create` method. You can extend the
+      capablilties of checkbox inputs in your applications by reopening this class. For example,
+      if you wanted to add a css class to all checkboxes in your application:
+    
+      ```javascript
+      import Checkbox from '@ember/component/checkbox';
+    
+      Checkbox.reopen({
+        classNames: ['my-app-checkbox']
+      });
+      ```

+      The `{{mount}}` helper lets you embed a routeless engine in a template.
+      Mounting an engine will cause an instance to be booted and its `application`

+      For example, the following template mounts the `ember-chat` engine:

+    /**
+      The `{{outlet}}` helper lets you specify where a child route will render in
+      your template. An important use of the `{{outlet}}` helper is in your
+      application's `application.hbs` file:
+    
+      ```handlebars
+      {{! app/templates/application.hbs }}
+      <!-- header content goes here, and will always display -->
+      {{my-header}}
+      <div class="my-dynamic-content">
+        <!-- this content will change based on the current route, which depends on the current URL -->
+        {{outlet}}
+      </div>
+      <!-- footer content goes here, and will always display -->
+      {{my-footer}}
+      ```
+    
+      You may also specify a name for the `{{outlet}}`, which is useful when using more than one
+      `{{outlet}}` in a template:
+    
+      ```handlebars
+      {{outlet "menu"}}
+      {{outlet "sidebar"}}
+      {{outlet "main"}}
+      ```
+    
+      Your routes can then render into a specific one of these `outlet`s by specifying the `outlet`
+      attribute in your `renderTemplate` function:
+    
+      ```app/routes/menu.js
+      import Route from '@ember/routing/route';
+    
+      export default Route.extend({
+        renderTemplate() {
+          this.render({ outlet: 'menu' });
+        }
+      });
+      ```
+    
+      See the [routing guide](https://guides.emberjs.com/release/routing/rendering-a-template/) for more
+      information on how your `route` interacts with the `{{outlet}}` helper.
+      Note: Your content __will not render__ if there isn't an `{{outlet}}` for it.

+    
+      If a view class with the same name exists, the view class also will be used.
+      Note: A given controller may only be used *once* in your app in this manner.
+      A singleton instance of the controller will be created for you.
+    
+      Example:
+    
+      ```app/controllers/navigation.js
+      import Controller from '@ember/controller';
+    
+      export default Controller.extend({

+      <h1>My great app</h1>
+      <div class='ember-view'>
+        Hello, world.
+      </div>
+      ```
+    
+      Optionally you may provide a second argument: a property path
+      that will be bound to the `model` property of the controller.
+      If a `model` property path is specified, then a new instance of the
+      controller will be created and `{{render}}` can be used multiple times
+      with the same name.
+    
+      For example if you had this `author` template.
+    
+      ```handlebars
+      <div class="author">
+        Written by {{firstName}} {{lastName}}.
+        Total Posts: {{postCount}}
+      </div>
+      ```

+      You could render it inside the `post` template using the `render` helper.
+    
+      ```handlebars
+      <div class="post">
+        <h1>{{title}}</h1>
+        <div>{{body}}</div>

+    /**
+      [Glimmer](https://github.com/tildeio/glimmer) is a templating engine used by Ember.js that is compatible with a subset of the [Handlebars](http://handlebarsjs.com/) syntax.
+    
+      ### Showing a property
+    
+      Templates manage the flow of an application's UI, and display state (through
+      the DOM) to a user. For example, given a component with the property "name",
+      that component's template can use the name in several ways:
+    
+      ```app/components/person-profile.js
+      import Component from '@ember/component';
+    
+      export default Component.extend({
+        name: 'Jill'
+      });
+      ```
+    
+      ```app/components/person-profile.hbs
+      {{name}}
+      <div>{{name}}</div>
+      <span data-name={{name}}></span>
+      ```
+    
+      Any time the "name" property on the component changes, the DOM will be
+      updated.
+    
+      Properties can be chained as well:
+    
+      ```handlebars
+      {{aUserModel.name}}
+      <div>{{listOfUsers.firstObject.name}}</div>
+      ```
+    
+      ### Using Ember helpers
+    
+      When content is passed in mustaches `{{}}`, Ember will first try to find a helper
+      or component with that name. For example, the `if` helper:
+    
+      ```handlebars
+      {{if name "I have a name" "I have no name"}}
+      <span data-has-name={{if name true}}></span>
+      ```
+    
+      The returned value is placed where the `{{}}` is called. The above style is
+      called "inline". A second style of helper usage is called "block". For example:
+    
+      ```handlebars
+      {{#if name}}
+      I have a name
+      {{else}}
+      I have no name
+      {{/if}}
+      ```
+    
+      The block form of helpers allows you to control how the UI is created based
+      on the values of properties.
+      A third form of helper is called "nested". For example here the concat
+      helper will add " Doe" to a displayed name if the person has no last name:
+    
+      ```handlebars
+      <span data-name={{concat firstName (
+      if lastName (concat " " lastName) "Doe"
+      )}}></span>
+      ```
+    
+      Ember's built-in helpers are described under the [Ember.Templates.helpers](/api/ember/release/classes/Ember.Templates.helpers)
+      namespace. Documentation on creating custom helpers can be found under
+      [Helper](/api/classes/Ember.Helper.html).
+    
+      ### Invoking a Component
+    
+      Ember components represent state to the UI of an application. Further
+      reading on components can be found under [Component](/api/ember/release/classes/Component).

+      NOTE: This is a low-level method used by other parts of the API. You almost
+      never want to call this method directly. Instead you should use
+      `mixin()` to define new properties.
+    
+      Defines a property on an object. This method works much like the ES5
+      `Object.defineProperty()` method except that it can also accept computed
+      properties and other special descriptors.
+    
+      Normally this method takes only three parameters. However if you pass an
+      instance of `Descriptor` as the third param then you can pass an
+      optional value as the fourth parameter. This is often more efficient than
+      creating new descriptor hashes for each property.
+    
+      ## Examples
+    
+      ```javascript
+      import { defineProperty, computed } from '@ember/object';
+    
+      // ES5 compatible mode
+      defineProperty(contact, 'firstName', {
+        writable: true,
+        configurable: false,
+        enumerable: true,
+        value: 'Charles'
+      });
+    
+      // define a simple property
+      defineProperty(contact, 'lastName', undefined, 'Jolley');
+    
+      // define a computed property
+      defineProperty(contact, 'fullName', computed('firstName', 'lastName', function() {
+        return this.firstName+' '+this.lastName;
+      }));
+      ```
+    
+      @private
+      @method defineProperty
+      @static
+      @for @ember/object
+      @param {Object} obj the object to define this property on. This may be a prototype.
+      @param {String} keyName the name of the property
+      @param {Descriptor} [desc] an instance of `Descriptor` (typically a
+        computed property) or an ES5 descriptor.
+        You must provide this or `data` but not both.
+      @param {*} [data] something other than a descriptor, that will
+        become the explicit value of this property.

+    
+      Marks a property as tracked.
+    
+      By default, a component's properties are expected to be static,
+      meaning you are not able to update them and have the template update accordingly.
+      Marking a property as tracked means that when that property changes,
+      a rerender of the component is scheduled so the template is kept up to date.
+    
+      There are two usages for the `@tracked` decorator, shown below.
+    
+      @example No dependencies
+    
+      If you don't pass an argument to `@tracked`, only changes to that property
+      will be tracked:
+    
+      ```typescript
+      import Component, { tracked } from '@glimmer/component';
+    
+      export default class MyComponent extends Component {
+        @tracked
+        remainingApples = 10
+      }
+      ```
+    
+      When something changes the component's `remainingApples` property, the rerender
+      will be scheduled.
+    
+      @example Dependents
+    
+      In the case that you have a computed property that depends other
+      properties, you want to track both so that when one of the
+      dependents change, a rerender is scheduled.
+    
+      In the following example we have two properties,
+      `eatenApples`, and `remainingApples`.
+    
+      ```typescript
+      import Component, { tracked } from '@glimmer/component';
+    
+      const totalApples = 100;
+    
+      export default class MyComponent extends Component {
+        @tracked
+        eatenApples = 0
+    
+        @tracked('eatenApples')
+        get remainingApples() {
+          return totalApples - this.eatenApples;
+        }
+    
+        increment() {
+          this.eatenApples = this.eatenApples + 1;
+        }
+      }
+      ```
+    
+      @param dependencies Optional dependents to be tracked.

+    /**
+      A computed property transforms an object literal with object's accessor function(s) into a property.
+    
+      By default the function backing the computed property will only be called
+      once and the result will be cached. You can specify various properties
+      that your computed property depends on. This will force the cached
+      result to be recomputed if the dependencies are modified.
+    
+      In the following example we declare a computed property - `fullName` - by calling
+      `computed` with property dependencies (`firstName` and `lastName`) as leading arguments and getter accessor function. The `fullName` getter function
+      will be called once (regardless of how many times it is accessed) as long
+      as its dependencies have not changed. Once `firstName` or `lastName` are updated
+      any future calls (or anything bound) to `fullName` will incorporate the new
+      values.
+    
+      ```javascript
+      import EmberObject, { computed } from '@ember/object';
+    
+      let Person = EmberObject.extend({
+        // these will be supplied by `create`
+        firstName: null,
+        lastName: null,
+    
+        fullName: computed('firstName', 'lastName', function() {
+          let firstName = this.get('firstName'),
+              lastName  = this.get('lastName');
+    
+          return `${firstName} ${lastName}`;
+        })
+      });
+    
+      let tom = Person.create({
+        firstName: 'Tom',
+        lastName: 'Dale'
+      });
+    
+      tom.get('fullName') // 'Tom Dale'
+      ```
+    
+      You can also define what Ember should do when setting a computed property by providing additional function (`set`) in hash argument.
+      If you try to set a computed property, it will try to invoke setter accessor function with the key and
+      value you want to set it to as arguments.
+    
+      ```javascript
+      import EmberObject, { computed } from '@ember/object';
+    
+      let Person = EmberObject.extend({
+        // these will be supplied by `create`
+        firstName: null,
+        lastName: null,
+    
+        fullName: computed('firstName', 'lastName', {
+          get(key) {
+            let firstName = this.get('firstName'),
+                lastName  = this.get('lastName');
+    
+            return firstName + ' ' + lastName;
+          },
+          set(key, value) {
+            let [firstName, lastName] = value.split(' ');
+    
+            this.set('firstName', firstName);
+            this.set('lastName', lastName);
+    
+            return value;
+          }
+        })
+      });
+    
+      let person = Person.create();
+    
+      person.set('fullName', 'Peter Wagenet');
+      person.get('firstName'); // 'Peter'
+      person.get('lastName');  // 'Wagenet'
+      ```
+    
+      You can overwrite computed property with normal property (no longer computed), that won't change if dependencies change, if you set computed property and it won't have setter accessor function defined.
+    
+      You can also mark computed property as `.readOnly()` and block all attempts to set it.
+    
+      ```javascript
+      import EmberObject, { computed } from '@ember/object';
+    
+      let Person = EmberObject.extend({
+        // these will be supplied by `create`
+        firstName: null,
+        lastName: null,
+    
+        fullName: computed('firstName', 'lastName', {
+          get(key) {
+            let firstName = this.get('firstName');
+            let lastName  = this.get('lastName');
+    
+            return firstName + ' ' + lastName;
+          }
+        }).readOnly()
+      });
+    
+      let person = Person.create();
+      person.set('fullName', 'Peter Wagenet'); // Uncaught Error: Cannot set read-only property "fullName" on object: <(...):emberXXX>

+      This helper returns a new property descriptor that wraps the passed
+      computed property function. You can use this helper to define properties
+      with mixins or via `defineProperty()`.
+    
+      If you pass a function as an argument, it will be used as a getter. A computed
+      property defined in this way might look like this:
+    
+      ```js
+      import EmberObject, { computed } from '@ember/object';
+    
+      let Person = EmberObject.extend({
+        init() {
+          this._super(...arguments);
+    
+          this.firstName = 'Betty';
+          this.lastName = 'Jones';
+        },
+    
+        fullName: computed('firstName', 'lastName', function() {
+          return `${this.get('firstName')} ${this.get('lastName')}`;
+        })
+      });
+    
+      let client = Person.create();
+    
+      client.get('fullName'); // 'Betty Jones'
+    
+      client.set('lastName', 'Fuller');
+      client.get('fullName'); // 'Betty Fuller'
+      ```
+    
+      You can pass a hash with two functions, `get` and `set`, as an
+      argument to provide both a getter and setter:
+    
+      ```js
+      import EmberObject, { computed } from '@ember/object';
+    
+      let Person = EmberObject.extend({
+        init() {
+          this._super(...arguments);
+    
+          this.firstName = 'Betty';
+          this.lastName = 'Jones';
+        },
+    
+        fullName: computed('firstName', 'lastName', {
+          get(key) {
+            return `${this.get('firstName')} ${this.get('lastName')}`;
+          },
+          set(key, value) {
+            let [firstName, lastName] = value.split(/\s+/);
+            this.setProperties({ firstName, lastName });
+            return value;
+          }
+        })
+      });
+    
+      let client = Person.create();
+      client.get('firstName'); // 'Betty'
+    
+      client.set('fullName', 'Carroll Fuller');
+      client.get('firstName'); // 'Carroll'
+      ```
+    
+      The `set` function should accept two parameters, `key` and `value`. The value
+      returned from `set` will be the new value of the property.
+    
+      _Note: This is the preferred way to define computed properties when writing third-party
+      libraries that depend on or use Ember, since there is no guarantee that the user
+      will have [prototype Extensions](https://guides.emberjs.com/release/configuring-ember/disabling-prototype-extensions/) enabled._
+    
+      The alternative syntax, with prototype extensions, might look like:
+    
+      ```js
+      fullName: function() {
+        return this.get('firstName') + ' ' + this.get('lastName');
+      }.property('firstName', 'lastName')
+      ```

+    HistoryLocation implements the location API using the browser's
+    history.pushState API.
+  
+    Using `HistoryLocation` results in URLs that are indistinguishable from a
+    standard URL. This relies upon the browser's `history` API.
+  
+    Example:
+  
+    ```app/router.js
+    Router.map(function() {
+      this.route('posts', function() {
+        this.route('new');
+      });
+    });
+  
+    Router.reopen({
+      location: 'history'
+    });
+    ```
+  
+    This will result in a posts.new url of `/posts/new`.
+  
+    Keep in mind that your server must serve the Ember app at all the routes you
+    define.

+         Computed properties allow you to treat a function like a property:
+         ```app/utils/president.js
+        import EmberObject from '@ember/object';
+         export default EmberObject.extend({
+          firstName: '',
+          lastName:  '',
+           fullName: function() {
+            return this.get('firstName') + ' ' + this.get('lastName');
+          }.property() // Call this flag to mark the function as a property
+        });
+        ```
+         ```javascript
+        let president = President.create({
+          firstName: 'Barack',
+          lastName: 'Obama'
+        });
+         president.get('fullName'); // 'Barack Obama'
+        ```
+         Treating a function like a property is useful because they can work with
+        bindings, just like any other property.
+         Many computed properties have dependencies on other properties. For
+        example, in the above example, the `fullName` property depends on
+        `firstName` and `lastName` to determine its value. You can tell Ember
+        about these dependencies like this:
+         ```app/utils/president.js
+        import EmberObject from '@ember/object';
+         export default EmberObject.extend({
+          firstName: '',
+          lastName:  '',
+           fullName: function() {
+            return this.get('firstName') + ' ' + this.get('lastName');
+             // Tell Ember.js that this computed property depends on firstName
+            // and lastName
+          }.property('firstName', 'lastName')
+        });
+        ```
+         Make sure you list these dependencies so Ember knows when to update
+        bindings that connect to a computed property. Changing a dependency
+        will not immediately trigger an update of the computed property, but
+        will instead clear the cache so that it is updated when the next `get`
+        is called on the property.
+         See [ComputedProperty](/api/ember/release/classes/ComputedProperty), [@ember/object/computed](/api/ember/release/classes/@ember%2Fobject%2Fcomputed).

+    This mixin implements Observer-friendly Array-like behavior. It is not a
+    concrete implementation, but it can be used up by other classes that want
+    to appear like arrays.
+  
+    For example, ArrayProxy is a concrete classes that can
+    be instantiated to implement array-like behavior. Both of these classes use
+    the Array Mixin by way of the MutableArray mixin, which allows observable
+    changes to be made to the underlying array.
+  
+    This mixin defines methods specifically for collections that provide
+    index-ordered access to their contents. When you are designing code that
+    needs to accept any kind of Array-like object, you should use these methods
+    instead of Array primitives because these will properly notify observers of
+    changes to the array.
+  
+    Although these methods are efficient, they do add a layer of indirection to
+    your application so it is a good idea to use them only when you need the
+    flexibility of using both true JavaScript arrays and "virtual" arrays such
+    as controllers and collections.
+  
+    You can use the methods defined in this module to access and modify array
+    contents in a KVO-friendly way. You can also be notified whenever the
+    membership of an array changes by using `.observes('myArray.[]')`.
+  
+    To support `EmberArray` in your own class, you must override two
+    primitives to use it: `length()` and `objectAt()`.

+      Retrieves the value of a property from the object.
+       This method is usually similar to using `object[keyName]` or `object.keyName`,
+      however it supports both computed properties and the unknownProperty
+      handler.
+       Because `get` unifies the syntax for accessing all these kinds
+      of properties, it can make many refactorings easier, such as replacing a
+      simple property with a computed property, or vice versa.
+       ### Computed Properties
+       Computed properties are methods defined with the `property` modifier
+      declared at the end, such as:
+       ```javascript
+      import { computed } from '@ember/object';
+       fullName: computed('firstName', 'lastName', function() {
+        return this.get('firstName') + ' ' + this.get('lastName');
+      })
+      ```
+       When you call `get` on a computed property, the function will be
+      called and the return value will be returned instead of the function
+      itself.
+       ### Unknown Properties
+       Likewise, if you try to call `get` on a property whose value is
+      `undefined`, the `unknownProperty()` method will be called on the object.
+      If this method returns any value other than `undefined`, it will be returned
+      instead. This allows you to implement "virtual" properties that are
+      not defined upfront.
+       @method get
+      @param {String} keyName The property to retrieve
+      @return {Object} The property value or undefined.
+      @public
+    */

+      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }

+      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+      ```

+
+    /**
+      Sets the provided key or path to the value.
+       ```javascript
+      record.set("key", value);
+      ```
+       This method is generally very similar to calling `object["key"] = value` or
+      `object.key = value`, except that it provides support for computed
+      properties, the `setUnknownProperty()` method and property observers.
+       ### Computed Properties
+       If you try to set a value on a key that has a computed property handler
+      defined (see the `get()` method for an example), then `set()` will call
+      that method, passing both the value and key instead of simply changing
+      the value itself. This is useful for those times when you need to
+      implement a property that is composed of one or more member
+      properties.
+       ### Unknown Properties
+       If you try to set a value on a key that is undefined in the target
+      object, then the `setUnknownProperty()` handler will be called instead. This
+      gives you an opportunity to implement complex "virtual" properties that
+      are not predefined on the object. If `setUnknownProperty()` returns
+      undefined, then `set()` will simply set the value on the object.
+       ### Property Observers
+       In addition to changing the property, `set()` will also register a property
+      change with the object. Unless you have placed this call inside of a
+      `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
+      (i.e. observer methods declared on the same object), will be called
+      immediately. Any "remote" observers (i.e. observer methods declared on
+      another object) will be placed in a queue and called at a later time in a
+      coalesced manner.
+       @method set
+      @param {String} keyName The property to set
+      @param {Object} value The value to set or `null`.

+       ### Observer Methods
+       Observer methods have the following signature:
+       ```app/components/my-component.js
+      import Component from '@ember/component';
+       export default Component.extend({
+        init() {
+          this._super(...arguments);
+          this.addObserver('foo', this, 'fooDidChange');
+        },
+         fooDidChange(sender, key, value, rev) {
+          // your code
+        }
+      });
+      ```
+       The `sender` is the object that changed. The `key` is the property that
+      changes. The `value` property is currently reserved and unused. The `rev`
+      is the last property revision of the object when it changed, which you can
+      use to detect if the key value has really changed or not.
+       Usually you will not need the value or revision parameters at
+      the end. In this case, it is common to write observer methods that take
+      only a sender and key value as parameters or, if you aren't interested in
+      any of these values, to write an observer that has no parameters at all.
+       @method addObserver

+    proxy.get('isSettled')  //=> false
+    proxy.get('isRejected')  //=> false

+    When the $.getJSON completes, and the promise is fulfilled
+    with json, the life cycle attributes will update accordingly.
+    Note that $.getJSON doesn't return an ECMA specified promise,

+    proxy.get('isRejected')  //=> false
+    proxy.get('isFulfilled') //=> true

+      Registers a factory that can be used for dependency injection (with

+       A simple example:
+       ```javascript
+      import Application from '@ember/application';
+      import EmberObject from '@ember/object';
+       let App = Application.create();
+       App.Orange = EmberObject.extend();
+      App.register('fruit:favorite', App.Orange);
+      ```
+       Ember will resolve factories from the `App` namespace automatically.
+      For example `App.CarsController` will be discovered and returned if
+      an application requests `controller:cars`.
+       An example of registering a controller with a non-standard name:
+       ```javascript
+      import Application from '@ember/application';
+      import Controller from '@ember/controller';
+       let App = Application.create();
+      let Session = Controller.extend();
+       App.register('controller:session', Session);
+       // The Session controller can now be treated like a normal controller,
+      // despite its non-standard name.
+      App.ApplicationController = Controller.extend({
+        needs: ['session']
+      });
+      ```
+       Registered factories are **instantiated** by having `create`
+      called on them. Additionally they are **singletons**, each time
+      they are looked up they return the same instance.
+       Some examples modifying that default behavior:
+       ```javascript
+      import Application from '@ember/application';
+      import EmberObject from '@ember/object';
+       let App = Application.create();
+       App.Person = EmberObject.extend();

+      App.register('communication:main', App.Email, { singleton: false });

+       When Ember instantiates a controller, view, or other framework component
+      it can attach a dependency to that component. This is often used to
+      provide services to a set of framework components.
+       An example of providing a session object to all controllers:
+       ```javascript
+      import { alias } from '@ember/object/computed';
+      import Application from '@ember/application';
+      import Controller from '@ember/controller';
+      import EmberObject from '@ember/object';

+      let Session = EmberObject.extend({ isAuthenticated: false });
+       // A factory must be registered before it can be injected
+      App.register('session:main', Session);
+       // Inject 'session:main' onto all factories of the type 'controller'
+      // with the name 'session'
+      App.inject('controller', 'session', 'session:main');
+       App.IndexController = Controller.extend({
+        isLoggedIn: alias('session.isAuthenticated')
+      });
+      ```
+       Injections can also be performed on specific factories.
+       ```javascript
+      App.inject(<full_name or type>, <property name>, <full_name>)
+      App.inject('route', 'source', 'source:main')
+      App.inject('route:application', 'email', 'model:email')
+      ```
+       It is important to note that injections can only be performed on

+    An ArrayProxy wraps any other object that implements `Array` and/or
+    `MutableArray,` forwarding all requests. This makes it very useful for
+    a number of binding use cases or other cases where being able to swap
+    out the underlying array is useful.
+  
+    A simple example of usage:
+  
+    ```javascript
+    import { A } from '@ember/array';
+    import ArrayProxy from '@ember/array/proxy';
+  
+    let pets = ['dog', 'cat', 'fish'];
+    let ap = ArrayProxy.create({ content: A(pets) });
+  
+    ap.get('firstObject');                        // 'dog'
+    ap.set('content', ['amoeba', 'paramecium']);
+    ap.get('firstObject');                        // 'amoeba'
+    ```
+  
+    This class can also be useful as a layer to transform the contents of
+    an array, as they are accessed. This can be done by overriding
+    `objectAtContent`:
+  
+    ```javascript
+    import { A } from '@ember/array';
+    import ArrayProxy from '@ember/array/proxy';
+  
+    let pets = ['dog', 'cat', 'fish'];
+    let ap = ArrayProxy.create({
+        content: A(pets),
+        objectAtContent: function(idx) {
+            return this.get('content').objectAt(idx).toUpperCase();
+        }
+    });
+  
+    ap.get('firstObject'); // . 'DOG'
+    ```
+  
+    When overriding this class, it is important to place the call to
+    `_super` *after* setting `content` so the internal observers have
+    a chance to fire properly:
+  
+    ```javascript
+    import { A } from '@ember/array';
+    import ArrayProxy from '@ember/array/proxy';
+  
+    export default ArrayProxy.extend({
+      init() {
+        this.set('content', A(['dog', 'cat', 'fish']));
+        this._super(...arguments);
+      }
+    });
+    ```

+      Strongly hint runtimes to intern the provided string.
+    
+      When do I need to use this function?
+    
+      For the most part, never. Pre-mature optimization is bad, and often the
+      runtime does exactly what you need it to, and more often the trade-off isn't
+      worth it.
+    
+      Why?
+    
+      Runtimes store strings in at least 2 different representations:
+      Ropes and Symbols (interned strings). The Rope provides a memory efficient
+      data-structure for strings created from concatenation or some other string
+      manipulation like splitting.
+    
+      Unfortunately checking equality of different ropes can be quite costly as
+      runtimes must resort to clever string comparison algorithms. These
+      algorithms typically cost in proportion to the length of the string.
+      Luckily, this is where the Symbols (interned strings) shine. As Symbols are
+      unique by their string content, equality checks can be done by pointer
+      comparison.
+    
+      How do I know if my string is a rope or symbol?
+    
+      Typically (warning general sweeping statement, but truthy in runtimes at
+      present) static strings created as part of the JS source are interned.
+      Strings often used for comparisons can be interned at runtime if some
+      criteria are met.  One of these criteria can be the size of the entire rope.
+      For example, in chrome 38 a rope longer then 12 characters will not
+      intern, nor will segments of that rope.

+    `TextSupport` is a shared mixin used by both `TextField` and

+    specify a controller action to invoke when a certain event is fired on your
+    text field or textarea. The specified controller action would get the current
+    value of the field passed in as the only argument unless the value of
+    the field is empty. In that case, the instance of the field itself is passed
+    in as the only argument.
+  
+    Let's use the pressing of the escape key as an example. If you wanted to
+    invoke a controller action when a user presses the escape key while on your
+    field, you would use the `escape-press` attribute on your field like so:
+  
+    ```handlebars
+      {{! application.hbs}}
+  
+      {{input escape-press='alertUser'}}
+    ```
+  
+    ```javascript
+        import Application from '@ember/application';
+        import Controller from '@ember/controller';
+        App = Application.create();
+  
+        App.ApplicationController = Controller.extend({
+          actions: {
+            alertUser: function ( currentValue ) {

+            }
+          }
+        });
+    ```
+  
+    The following chart is a visual representation of what takes place when the
+    escape key is pressed in this scenario:

+    `RSVP.Promise.all` accepts an array of promises, and returns a new promise which
+    is fulfilled with an array of fulfillment values for the passed promises, or
+    rejected with the reason of the first passed promise to be rejected. It casts all
+    elements of the passed iterable to promises as it runs this algorithm.
+  
+    Example:
+  
+    ```javascript
+    let promise1 = RSVP.resolve(1);
+    let promise2 = RSVP.resolve(2);
+    let promise3 = RSVP.resolve(3);

+    Example:
+  
+    ```javascript
+    let promise1 = RSVP.resolve(1);

+    ```
+  
+    `RSVP.Promise.race` is deterministic in that only the state of the first
+    settled promise matters. For example, even if other promises given to the
+    `promises` array argument are resolved, but the first settled promise has
+    become rejected before the other promises became fulfilled, the returned
+    promise will become rejected:
+  
+    ```javascript

+    });
+    ```
+  
+    An example real-world use case is implementing timeouts:

+    ```

+    Promise objects represent the eventual result of an asynchronous operation. The
+    primary way of interacting with a promise is through its `then` method, which
+    registers callbacks to receive either a promise’s eventual value or the reason
+    why the promise cannot be fulfilled.
+  
+    Terminology
+    -----------
+  
+    - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+    - `thenable` is an object or function that defines a `then` method.
+    - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+    - `exception` is a value that is thrown using the throw statement.
+    - `reason` is a value that indicates why a promise was rejected.
+    - `settled` the final resting state of a promise, fulfilled or rejected.
+  
+    A promise can be in one of three states: pending, fulfilled, or rejected.
+  
+    Promises that are fulfilled have a fulfillment value and are in the fulfilled
+    state.  Promises that are rejected have a rejection reason and are in the
+    rejected state.  A fulfillment value is never a thenable.
+  
+    Promises can also be said to *resolve* a value.  If this value is also a
+    promise, then the original promise's settled state will match the value's
+    settled state.  So a promise that *resolves* a promise that rejects will
+    itself reject, and a promise that *resolves* a promise that fulfills will
+    itself fulfill.
+  
+  
+    Basic Usage:
+    ------------
+  
+    ```js
+    let promise = new Promise(function(resolve, reject) {
+      // on success
+      resolve(value);
+  
+      // on failure
+      reject(reason);
+    });
+  
+    promise.then(function(value) {
+      // on fulfillment
+    }, function(reason) {
+      // on rejection
+    });
+    ```
+  
+    Advanced Usage:
+    ---------------
+  
+    Promises shine when abstracting away asynchronous interactions such as
+    `XMLHttpRequest`s.
+  
+    ```js
+    function getJSON(url) {
+      return new Promise(function(resolve, reject){
+        let xhr = new XMLHttpRequest();
+  
+        xhr.open('GET', url);
+        xhr.onreadystatechange = handler;
+        xhr.responseType = 'json';
+        xhr.setRequestHeader('Accept', 'application/json');
+        xhr.send();
+  
+        function handler() {
+          if (this.readyState === this.DONE) {
+            if (this.status === 200) {
+              resolve(this.response);
+            } else {
+              reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+            }
+          }
+        };
+      });
+    }
+  
+    getJSON('/posts.json').then(function(json) {
+      // on fulfillment
+    }, function(reason) {
+      // on rejection
+    });
+    ```
+  
+    Unlike callbacks, promises are great composable primitives.
+  
+    ```js
+    Promise.all([
+      getJSON('/posts'),
+      getJSON('/comments')
+    ]).then(function(values){
+      values[0] // => postsJSON
+      values[1] // => commentsJSON
+  
+      return values;
+    });

+    The primary way of interacting with a promise is through its `then` method,
+    which registers callbacks to receive either a promise's eventual value or the
+    reason why the promise cannot be fulfilled.
+  
+    ```js
+    findUser().then(function(user){
+      // user is available
+    }, function(reason){
+      // user is unavailable, and you are given the reason why
+    });
+    ```
+  
+    Chaining
+    --------
+  
+    The return value of `then` is itself a promise.  This second, 'downstream'
+    promise is resolved with the return value of the first promise's fulfillment
+    or rejection handler, or rejected if the handler throws an exception.
+  
+    ```js
+    findUser().then(function (user) {
+      return user.name;
+    }, function (reason) {
+      return 'default name';
+    }).then(function (userName) {
+      // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+      // will be `'default name'`
+    });
+  
+    findUser().then(function (user) {
+      throw new Error('Found user, but still unhappy');
+    }, function (reason) {
+      throw new Error('`findUser` rejected and we\'re unhappy');
+    }).then(function (value) {
+      // never reached
+    }, function (reason) {
+      // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+      // If `findUser` rejected, `reason` will be '`findUser` rejected and we\'re unhappy'.
+    });
+    ```
+    If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+  
+    ```js
+    findUser().then(function (user) {
+      throw new PedagogicalException('Upstream error');
+    }).then(function (value) {
+      // never reached
+    }).then(function (value) {
+      // never reached
+    }, function (reason) {
+      // The `PedgagocialException` is propagated all the way down to here
+    });
+    ```
+  
+    Assimilation
+    ------------
+  
+    Sometimes the value you want to propagate to a downstream promise can only be
+    retrieved asynchronously. This can be achieved by returning a promise in the
+    fulfillment or rejection handler. The downstream promise will then be pending
+    until the returned promise is settled. This is called *assimilation*.
+  
+    ```js
+    findUser().then(function (user) {
+      return findCommentsByAuthor(user);
+    }).then(function (comments) {
+      // The user's comments are now available
+    });
+    ```
+  
+    If the assimliated promise rejects, then the downstream promise will also reject.
+  
+    ```js
+    findUser().then(function (user) {
+      return findCommentsByAuthor(user);
+    }).then(function (comments) {
+      // If `findCommentsByAuthor` fulfills, we'll have the value here
+    }, function (reason) {
+      // If `findCommentsByAuthor` rejects, we'll have the reason here
+    });
+    ```
+  
+    Simple Example
+    --------------
+  
+    Synchronous Example
+  
+    ```javascript
+    let result;
+  
+    try {
+      result = findResult();

+    `RSVP.denodeify` takes a 'node-style' function and returns a function that
+    will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
+    browser when you'd prefer to use promises over using callbacks. For example,
+    `denodeify` transforms the following:
+  
+    ```javascript
+    let fs = require('fs');
+  
+    fs.readFile('myfile.txt', function(err, data){
+      if (err) return handleError(err);
+      handleData(data);
+    });
+    ```
+  
+    into:
+  
+    ```javascript
+    let fs = require('fs');
+    let readFile = RSVP.denodeify(fs.readFile);
+  
+    readFile('myfile.txt').then(handleData, handleError);
+    ```
+  
+    If the node function has multiple success parameters, then `denodeify`
+    just returns the first one:
+  
+    ```javascript
+    let request = RSVP.denodeify(require('request'));
+  
+    request('http://example.com').then(function(res) {
+      // ...
+    });
+    ```
+  
+    However, if you need all success parameters, setting `denodeify`'s
+    second parameter to `true` causes it to return all success parameters
+    as an array:
+  
+    ```javascript
+    let request = RSVP.denodeify(require('request'), true);
+  
+    request('http://example.com').then(function(result) {
+      // result[0] -> res
+      // result[1] -> body
+    });
+    ```
+  
+    Or if you pass it an array with names it returns the parameters as a hash:
+  
+    ```javascript
+    let request = RSVP.denodeify(require('request'), ['res', 'body']);
+  
+    request('http://example.com').then(function(result) {
+      // result.res
+      // result.body
+    });
+    ```
+  
+    Sometimes you need to retain the `this`:
+  
+    ```javascript
+    let app = require('express')();
+    let render = RSVP.denodeify(app.render.bind(app));
+    ```
+  
+    The denodified function inherits from the original function. It works in all
+    environments, except IE 10 and below. Consequently all properties of the original
+    function are available to you. However, any properties you change on the
+    denodeified function won't be changed on the original function. Example:
+  
+    ```javascript
+    let request = RSVP.denodeify(require('request')),
+        cookieJar = request.jar(); // <- Inheritance is used here
+  
+    request('http://example.com', {jar: cookieJar}).then(function(res) {
+      // cookieJar.cookies holds now the cookies returned by example.com
+    });
+    ```
+  
+    Using `denodeify` makes it easier to compose asynchronous operations instead
+    of using callbacks. For example, instead of:
+  
+    ```javascript
+    let fs = require('fs');
+  
+    fs.readFile('myfile.txt', function(err, data){
+      if (err) { ... } // Handle error
+      fs.writeFile('myfile2.txt', data, function(err){
+        if (err) { ... } // Handle error
+        console.log('done')
+      });
+    });
+    ```
+  
+    you can chain the operations together using `then` from the returned promise:
+  
+    ```javascript
+    let fs = require('fs');
+    let readFile = RSVP.denodeify(fs.readFile);
+    let writeFile = RSVP.denodeify(fs.writeFile);
+  
+    readFile('myfile.txt').then(function(data){
+      return writeFile('myfile2.txt', data);
+    }).then(function(){
+      console.log('done')
+    }).catch(function(error){
+      // Handle error

+  
+    ```js

+  
+    inflector.pluralize('cow'); //=> 'kine'
+    inflector.singularize('kine'); //=> 'cow'
+    ```
+  
+    Creating an inflector and adding rules later.
+  
+    ```javascript
+    var inflector = Ember.Inflector.inflector;
+  
+    inflector.pluralize('advice'); // => 'advices'
+    inflector.uncountable('advice');
+    inflector.pluralize('advice'); // => 'advice'

+    An adapter is an object that receives requests from a store and
+    translates them into the appropriate action to take against your
+    persistence layer. The persistence layer is usually an HTTP API but
+    may be anything, such as the browser's local storage. Typically the
+    adapter is not invoked directly instead its functionality is accessed
+    through the `store`.
+  
+    ### Creating an Adapter
+  
+    Create a new subclass of `DS.Adapter` in the `app/adapters` folder:
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+  
+    export default DS.Adapter.extend({
+      // ...your code here
+    });
+    ```
+  
+    Model-specific adapters can be created by putting your adapter
+    class in an `app/adapters/` + `model-name` + `.js` file of the application.
+  
+    ```app/adapters/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Adapter.extend({
+      // ...Post-specific adapter code goes here
+    });
+    ```
+  
+    `DS.Adapter` is an abstract base class that you should override in your
+    application to customize it for your backend. The minimum set of methods
+    that you should implement is:
+  
+      * `findRecord()`
+      * `createRecord()`
+      * `updateRecord()`
+      * `deleteRecord()`
+      * `findAll()`
+      * `query()`
+  
+    To improve the network performance of your application, you can optimize
+    your adapter by overriding these lower-level methods:
+  
+      * `findMany()`
+  
+  
+    For an example of the implementation, see `DS.RESTAdapter`, the
+    included REST adapter.
+  
+    @class Adapter
+    @namespace DS

+       Note the `defaultSerializer` serializer has a lower priority than
+      a model specific serializer (i.e. `PostSerializer`) or the
+      `application` serializer.
+       ```app/adapters/django.js
+      import DS from 'ember-data';

+    `DS.attr` defines an attribute on a [DS.Model](/api/data/classes/DS.Model.html).
+    By default, attributes are passed through as-is, however you can specify an
+    optional type to have the value automatically transformed.
+    Ember Data ships with four basic transform types: `string`, `number`,
+    `boolean` and `date`. You can define your own transforms by subclassing
+    [DS.Transform](/api/data/classes/DS.Transform.html).
+  
+    Note that you cannot use `attr` to define an attribute of `id`.
+  
+    `DS.attr` takes an optional hash as a second parameter, currently
+    supported options are:
+  
+    - `defaultValue`: Pass a string or a function to be called to set the attribute
+    to a default value if none is supplied.
+  
+    Example
+  
+    ```app/models/user.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      username: DS.attr('string'),
+      email: DS.attr('string'),
+      verified: DS.attr('boolean', { defaultValue: false })
+    });
+    ```
+  
+    Default value can also be a function. This is useful it you want to return
+    a new object for each attribute.
+  
+    ```app/models/user.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      username: DS.attr('string'),
+      email: DS.attr('string'),
+      settings: DS.attr({
+        defaultValue() {
+          return {};
+        }
+      })
+    });
+    ```
+  
+    The `options` hash is passed as second argument to a transforms'
+    `serialize` and `deserialize` method. This allows to configure a
+    transformation and adapt the corresponding value, based on the config:
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      text: DS.attr('text', {
+        uppercase: true
+      })
+    });
+    ```
+  
+    ```app/transforms/text.js
+    import DS from 'ember-data';
+  
+    export default DS.Transform.extend({
+      serialize(value, options) {
+        if (options.uppercase) {
+          return value.toUpperCase();
+        }
+  
+        return value;
+      },
+  
+      deserialize(value) {
+        return value;
+      }
+    })
+    ```
+  
+    @namespace
+    @method attr
+    @for DS
+    @param {String|Object} type the attribute type
+    @param {Object} options a hash of options

+    The `JSONAPIAdapter` is the default adapter used by Ember Data. It
+    is responsible for transforming the store's requests into HTTP
+    requests that follow the [JSON API](http://jsonapi.org/format/)
+    format.
+  
+    ## JSON API Conventions
+  
+    The JSONAPIAdapter uses JSON API conventions for building the URL
+    for a record and selecting the HTTP verb to use with a request. The
+    actions you can take on a record map onto the following URLs in the
+    JSON API adapter:
+  
+  <table>
+    <tr>
+      <th>
+        Action
+      </th>
+      <th>
+        HTTP Verb
+      </th>
+      <th>
+        URL
+      </th>
+    </tr>
+    <tr>
+      <th>
+        `store.findRecord('post', 123)`
+      </th>
+      <td>
+        GET
+      </td>
+      <td>
+        /posts/123
+      </td>
+    </tr>
+    <tr>
+      <th>
+        `store.findAll('post')`
+      </th>
+      <td>
+        GET
+      </td>
+      <td>
+        /posts
+      </td>
+    </tr>
+    <tr>
+      <th>
+        Update `postRecord.save()`
+      </th>
+      <td>
+        PATCH
+      </td>
+      <td>
+        /posts/123
+      </td>
+    </tr>
+    <tr>
+      <th>
+        Create `store.createRecord('post').save()`
+      </th>
+      <td>
+        POST
+      </td>
+      <td>
+        /posts
+      </td>
+    </tr>
+    <tr>
+      <th>
+        Delete `postRecord.destroyRecord()`
+      </th>
+      <td>
+        DELETE
+      </td>
+      <td>
+        /posts/123
+      </td>
+    </tr>
+  </table>
+  
+    ## Success and failure
+  
+    The JSONAPIAdapter will consider a success any response with a
+    status code of the 2xx family ("Success"), as well as 304 ("Not
+    Modified"). Any other status code will be considered a failure.
+  
+    On success, the request promise will be resolved with the full
+    response payload.
+  
+    Failed responses with status code 422 ("Unprocessable Entity") will
+    be considered "invalid". The response will be discarded, except for
+    the `errors` key. The request promise will be rejected with a
+    `DS.InvalidError`. This error object will encapsulate the saved
+    `errors` value.
+  
+    Any other status codes will be treated as an adapter error. The
+    request promise will be rejected, similarly to the invalid case,
+    but with an instance of `DS.AdapterError` instead.
+  
+    ### Endpoint path customization
+  
+    Endpoint paths can be prefixed with a `namespace` by setting the
+    namespace property on the adapter:
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+  
+    export default DS.JSONAPIAdapter.extend({
+      namespace: 'api/1'
+    });
+    ```
+    Requests for the `person` model would now target `/api/1/people/1`.
+  
+    ### Host customization
+  
+    An adapter can target other hosts by setting the `host` property.

+      within a single runloop.
+       For example, if you have an initial payload of:
+       ```javascript
+      {
+        data: {
+          id: 1,
+          type: 'post',
+          relationship: {

+                { id: 2, type: 'comment' }
+              ]
+            }
+          }
+        }
+      }
+      ```
+       By default calling `post.get('comments')` will trigger the following requests(assuming the
+      comments haven't been loaded before):
+       ```
+      GET /comments/1
+      GET /comments/2
+      ```
+       If you set coalesceFindRequests to `true` it will instead trigger the following request:
+       ```
+      GET /comments?filter[id]=1,2
+      ```
+       Setting coalesceFindRequests to `true` also works for `store.find` requests and `belongsTo`
+      relationships accessed within the same runloop. If you set `coalesceFindRequests: true`
+       ```javascript
+      store.findRecord('comment', 1);
+      store.findRecord('comment', 2);
+      ```
+       will also send a request to: `GET /comments?filter[id]=1,2`

+    The REST adapter allows your store to communicate with an HTTP server by
+    transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
+    should use the REST adapter.
+  
+    This adapter is designed around the idea that the JSON exchanged with
+    the server should be conventional.
+  
+    ## Success and failure
+  
+    The REST adapter will consider a success any response with a status code
+    of the 2xx family ("Success"), as well as 304 ("Not Modified"). Any other
+    status code will be considered a failure.
+  
+    On success, the request promise will be resolved with the full response
+    payload.
+  
+    Failed responses with status code 422 ("Unprocessable Entity") will be
+    considered "invalid". The response will be discarded, except for the
+    `errors` key. The request promise will be rejected with a `DS.InvalidError`.
+    This error object will encapsulate the saved `errors` value.
+  
+    Any other status codes will be treated as an "adapter error". The request
+    promise will be rejected, similarly to the "invalid" case, but with
+    an instance of `DS.AdapterError` instead.
+  
+    ## JSON Structure
+  
+    The REST adapter expects the JSON returned from your server to follow
+    these conventions.
+  
+    ### Object Root
+  
+    The JSON payload should be an object that contains the record inside a
+    root property. For example, in response to a `GET` request for
+    `/posts/1`, the JSON should look like this:
+  
+    ```js
+    {
+      "posts": {
+        "id": 1,
+        "title": "I'm Running to Reform the W3C's Tag",
+        "author": "Yehuda Katz"
+      }
+    }
+    ```
+  
+    Similarly, in response to a `GET` request for `/posts`, the JSON should
+    look like this:
+  
+    ```js
+    {
+      "posts": [
+        {
+          "id": 1,
+          "title": "I'm Running to Reform the W3C's Tag",
+          "author": "Yehuda Katz"
+        },
+        {
+          "id": 2,
+          "title": "Rails is omakase",
+          "author": "D2H"
+        }
+      ]
+    }
+    ```
+  
+    Note that the object root can be pluralized for both a single-object response
+    and an array response: the REST adapter is not strict on this. Further, if the
+    HTTP server responds to a `GET` request to `/posts/1` (e.g. the response to a
+    `findRecord` query) with more than one object in the array, Ember Data will
+    only display the object with the matching ID.
+  
+    ### Conventional Names
+  
+    Attribute names in your JSON payload should be the camelCased versions of
+    the attributes in your Ember.js models.
+  
+    For example, if you have a `Person` model:
+  
+    ```app/models/person.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      firstName: DS.attr('string'),
+      lastName: DS.attr('string'),
+      occupation: DS.attr('string')
+    });
+    ```
+  
+    The JSON returned should look like this:
+  
+    ```js
+    {
+      "people": {
+        "id": 5,
+        "firstName": "Zaphod",
+        "lastName": "Beeblebrox",
+        "occupation": "President"
+      }
+    }
+    ```
+  
+    #### Relationships
+  
+    Relationships are usually represented by ids to the record in the
+    relationship. The related records can then be sideloaded in the
+    response under a key for the type.
+  
+    ```js
+    {
+      "posts": {
+        "id": 5,
+        "title": "I'm Running to Reform the W3C's Tag",
+        "author": "Yehuda Katz",
+        "comments": [1, 2]
+      },
+      "comments": [{
+        "id": 1,
+        "author": "User 1",
+        "message": "First!",
+      }, {
+        "id": 2,
+        "author": "User 2",
+        "message": "Good Luck!",
+      }]
+    }
+    ```
+  
+    If the records in the relationship are not known when the response
+    is serialized it's also possible to represent the relationship as a
+    URL using the `links` key in the response. Ember Data will fetch
+    this URL to resolve the relationship when it is accessed for the
+    first time.
+  
+    ```js
+    {
+      "posts": {
+        "id": 5,
+        "title": "I'm Running to Reform the W3C's Tag",
+        "author": "Yehuda Katz",
+        "links": {
+          "comments": "/posts/5/comments"
+        }
+      }
+    }
+    ```
+  
+    ### Errors
+  
+    If a response is considered a failure, the JSON payload is expected to include
+    a top-level key `errors`, detailing any specific issues. For example:
+  
+    ```js
+    {
+      "errors": {
+        "msg": "Something went wrong"
+      }
+    }
+    ```
+  
+    This adapter does not make any assumptions as to the format of the `errors`
+    object. It will simply be passed along as is, wrapped in an instance
+    of `DS.InvalidError` or `DS.AdapterError`. The serializer can interpret it
+    afterwards.
+  
+    ## Customization
+  
+    ### Endpoint path customization
+  
+    Endpoint paths can be prefixed with a `namespace` by setting the namespace
+    property on the adapter:
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+  
+    export default DS.RESTAdapter.extend({
+      namespace: 'api/1'
+    });
+    ```
+    Requests for the `Person` model would now target `/api/1/people/1`.
+  
+    ### Host customization
+  
+    An adapter can target other hosts by setting the `host` property.
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+  
+    export default DS.RESTAdapter.extend({
+      host: 'https://api.example.com'
+    });
+    ```
+  
+    ### Headers customization
+  
+    Some APIs require HTTP headers, e.g. to provide an API key. Arbitrary
+    headers can be set as key/value pairs on the `RESTAdapter`'s `headers`
+    object and Ember Data will send them along with each ajax request.
+  
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+    import { computed } from '@ember/object';
+  
+    export default DS.RESTAdapter.extend({
+      headers: computed(function() {
+        return {
+          'API_KEY': 'secret key',
+          'ANOTHER_HEADER': 'Some header value'
+        };
+      }
+    });
+    ```
+  
+    `headers` can also be used as a computed property to support dynamic
+    headers. In the example below, the `session` object has been
+    injected into an adapter by Ember's container.
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+    import { computed } from '@ember/object';
+  
+    export default DS.RESTAdapter.extend({
+      headers: computed('session.authToken', function() {
+        return {
+          'API_KEY': this.get('session.authToken'),
+          'ANOTHER_HEADER': 'Some header value'
+        };
+      })
+    });
+    ```
+  
+    In some cases, your dynamic headers may require data from some
+    object outside of Ember's observer system (for example
+    `document.cookie`). You can use the
+    [volatile](/api/classes/Ember.ComputedProperty.html#method_volatile)
+    function to set the property into a non-cached mode causing the headers to
+    be recomputed with every request.
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+    import { get } from '@ember/object';
+    import { computed } from '@ember/object';
+  
+    export default DS.RESTAdapter.extend({
+      headers: computed(function() {
+        return {
+          'API_KEY': get(document.cookie.match(/apiKey\=([^;]*)/), '1'),
+          'ANOTHER_HEADER': 'Some header value'
+        };
+      }).volatile()
+    });
+    ```
+  
+    @class RESTAdapter
+    @constructor
+    @namespace DS
+    @extends DS.Adapter
+    @uses DS.BuildURLMixin
+  */
+
+  var RESTAdapter = _adapter.default.extend(_private.BuildURLMixin, {
+    defaultSerializer: '-rest',
+    fastboot: Ember.computed(function () {
+      return Ember.getOwner(this).lookup('service:fastboot');
+    }),
+
+    /**
+      By default, the RESTAdapter will send the query params sorted alphabetically to the
+      server.
+       For example:
+       ```js
+      store.query('posts', { sort: 'price', category: 'pets' });
+      ```
+       will generate a requests like this `/posts?category=pets&sort=price`, even if the
+      parameters were specified in a different order.
+       That way the generated URL will be deterministic and that simplifies caching mechanisms
+      in the backend.
+       Setting `sortQueryParams` to a falsey value will respect the original order.
+       In case you want to sort the query parameters with a different criteria, set

+    ## Using Embedded Records
+  
+    `DS.EmbeddedRecordsMixin` supports serializing embedded records.
+  
+    To set up embedded records, include the mixin when extending a serializer,
+    then define and configure embedded (model) relationships.
+  
+    Note that embedded records will serialize with the serializer for their model instead of the serializer in which they are defined.
+  
+    Below is an example of a per-type serializer (`post` type).
+  
+    ```app/serializers/post.js
+    import DS from 'ember-data';
+  
+    export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
+      attrs: {
+        author: { embedded: 'always' },
+        comments: { serialize: 'ids' }
+      }
+    });
+    ```
+    Note that this use of `{ embedded: 'always' }` is unrelated to
+    the `{ embedded: 'always' }` that is defined as an option on `DS.attr` as part of
+    defining a model while working with the `ActiveModelSerializer`.  Nevertheless,
+    using `{ embedded: 'always' }` as an option to `DS.attr` is not a valid way to set up
+    embedded records.
+  
+    The `attrs` option for a resource `{ embedded: 'always' }` is shorthand for:
+  
+    ```js
+    {
+      serialize: 'records',
+      deserialize: 'records'
+    }
+    ```
+  
+    ### Configuring Attrs
+  
+    A resource's `attrs` option may be set to use `ids`, `records` or false for the
+    `serialize`  and `deserialize` settings.
+  
+    The `attrs` property can be set on the `ApplicationSerializer` or a per-type
+    serializer.
+  
+    In the case where embedded JSON is expected while extracting a payload (reading)
+    the setting is `deserialize: 'records'`, there is no need to use `ids` when
+    extracting as that is the default behaviour without this mixin if you are using
+    the vanilla `EmbeddedRecordsMixin`. Likewise, to embed JSON in the payload while
+    serializing `serialize: 'records'` is the setting to use. There is an option of
+    not embedding JSON in the serialized payload by using `serialize: 'ids'`. If you
+    do not want the relationship sent at all, you can use `serialize: false`.
+  
+  
+    ### EmbeddedRecordsMixin defaults
+    If you do not overwrite `attrs` for a specific relationship, the `EmbeddedRecordsMixin`
+    will behave in the following way:
+  
+    BelongsTo: `{ serialize: 'id', deserialize: 'id' }`
+    HasMany:   `{ serialize: false, deserialize: 'ids' }`
+  
+    ### Model Relationships
+  
+    Embedded records must have a model defined to be extracted and serialized. Note that
+    when defining any relationships on your model such as `belongsTo` and `hasMany`, you
+    should not both specify `async: true` and also indicate through the serializer's
+    `attrs` attribute that the related model should be embedded for deserialization.
+    If a model is declared embedded for deserialization (`embedded: 'always'` or `deserialize: 'records'`),
+    then do not use `async: true`.
+  
+    To successfully extract and serialize embedded records the model relationships
+    must be set up correctly. See the
+    [defining relationships](/guides/models/defining-models/#toc_defining-relationships)
+    section of the **Defining Models** guide page.
+  
+    Records without an `id` property are not considered embedded records, model
+    instances must have an `id` property to be used with Ember Data.
+  
+    ### Example JSON payloads, Models and Serializers
+  
+    **When customizing a serializer it is important to grok what the customizations
+    are. Please read the docs for the methods this mixin provides, in case you need
+    to modify it to fit your specific needs.**
+  
+    For example, review the docs for each method of this mixin:
+    * [normalize](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_normalize)
+    * [serializeBelongsTo](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_serializeBelongsTo)
+    * [serializeHasMany](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_serializeHasMany)

+       This example of a post model has many comments:
+       ```js
+      Post = DS.Model.extend({
+        title:    DS.attr('string'),
+        body:     DS.attr('string'),
+        comments: DS.hasMany('comment')
+      });
+       Comment = DS.Model.extend({
+        body:     DS.attr('string'),
+        post:     DS.belongsTo('post')
+      });
+      ```
+       Use a custom (type) serializer for the post model to configure embedded comments
+       ```app/serializers/post.js
+      import DS from 'ember-data;
+       export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
+        attrs: {
+          comments: { embedded: 'always' }
+        }
+      })
+      ```
+       A payload with an attribute configured for embedded records can serialize
+      the records together under the root attribute's payload:
+       ```js
+      {
+        "post": {
+          "id": "1"
+          "title": "Rails is omakase",
+          "body": "I want this for my ORM, I want that for my template language..."
+          "comments": [{
+            "id": "1",
+            "body": "Rails is unagi"
+          }, {
+            "id": "2",
+            "body": "Omakase O_o"
+          }]
+        }
+      }
+      ```
+       The attrs options object can use more specific instruction for extracting and
+      serializing. When serializing, an option to embed `ids`, `ids-and-types` or `records` can be set.
+      When extracting the only option is `records`.
+       So `{ embedded: 'always' }` is shorthand for:
+      `{ serialize: 'records', deserialize: 'records' }`
+       To embed the `ids` for a related object (using a hasMany relationship):
+       ```app/serializers/post.js
+      import DS from 'ember-data;
+       export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
+        attrs: {
+          comments: { serialize: 'ids', deserialize: 'records' }
+        }
+      })
+      ```
+       ```js
+      {
+        "post": {
+          "id": "1"
+          "title": "Rails is omakase",
+          "body": "I want this for my ORM, I want that for my template language..."
+          "comments": ["1", "2"]
+        }
+      }
+      ```
+       To embed the relationship as a collection of objects with `id` and `type` keys, set
+      `ids-and-types` for the related object.
+       This is particularly useful for polymorphic relationships where records don't share
+      the same table and the `id` is not enough information.
+       For example having a user that has many pets:
+       ```js
+      User = DS.Model.extend({
+        name:    DS.attr('string'),
+        pets: DS.hasMany('pet', { polymorphic: true })
+      });
+       Pet = DS.Model.extend({

+    Ember Data 2.0 Serializer:
+  
+    In Ember Data a Serializer is used to serialize and deserialize
+    records when they are transferred in and out of an external source.
+    This process involves normalizing property names, transforming
+    attribute values and serializing relationships.
+  
+    `JSONAPISerializer` supports the http://jsonapi.org/ spec and is the
+    serializer recommended by Ember Data.
+  
+    This serializer normalizes a JSON API payload that looks like:
+  
+    ```app/models/player.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      name: DS.attr('string'),
+      skill: DS.attr('string'),
+      gamesPlayed: DS.attr('number'),
+      club: DS.belongsTo('club')
+    });
+    ```
+  
+    ```app/models/club.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      name: DS.attr('string'),
+      location: DS.attr('string'),
+      players: DS.hasMany('player')
+    });
+    ```
+  
+    ```js
+      {
+        "data": [
+          {
+            "attributes": {
+              "name": "Benfica",
+              "location": "Portugal"
+            },
+            "id": "1",
+            "relationships": {
+              "players": {
+                "data": [
+                  {
+                    "id": "3",
+                    "type": "players"
+                  }
+                ]
+              }
+            },
+            "type": "clubs"
+          }
+        ],
+        "included": [
+          {
+            "attributes": {
+              "name": "Eusebio Silva Ferreira",
+              "skill": "Rocket shot",
+              "games-played": 431
+            },

+            "relationships": {
+              "club": {
+                "data": {
+                  "id": "1",
+                  "type": "clubs"
+                }
+              }
+            },
+            "type": "players"
+          }
+        ]
+      }
+    ```
+  
+    to the format that the Ember Data store expects.
+  
+    ### Customizing meta
+  
+    Since a JSON API Document can have meta defined in multiple locations you can
+    use the specific serializer hooks if you need to customize the meta.
+  
+    One scenario would be to camelCase the meta keys of your payload. The example
+    below shows how this could be done using `normalizeArrayResponse` and
+    `extractRelationship`.
+  
+    ```app/serializers/application.js
+    export default JSONAPISerializer.extend({
+      normalizeArrayResponse(store, primaryModelClass, payload, id, requestType) {
+        let normalizedDocument = this._super(...arguments);
+  
+        // Customize document meta
+        normalizedDocument.meta = camelCaseKeys(normalizedDocument.meta);
+  
+        return normalizedDocument;
+      },
+  
+      extractRelationship(relationshipHash) {
+        let normalizedRelationship = this._super(...arguments);
+  
+        // Customize relationship meta
+        normalizedRelationship.meta = camelCaseKeys(normalizedRelationship.meta);
+  
+        return normalizedRelationship;
+      }
+    });
+    ```

+    Ember Data 2.0 Serializer:
+  
+    In Ember Data a Serializer is used to serialize and deserialize
+    records when they are transferred in and out of an external source.
+    This process involves normalizing property names, transforming
+    attribute values and serializing relationships.
+  
+    By default, Ember Data uses and recommends the `JSONAPISerializer`.
+  
+    `JSONSerializer` is useful for simpler or legacy backends that may
+    not support the http://jsonapi.org/ spec.
+  
+    For example, given the following `User` model and JSON payload:
+  
+    ```app/models/user.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      friends: DS.hasMany('user'),
+      house: DS.belongsTo('location'),
+  
+      name: DS.attr('string')
+    });
+    ```
+  
+    ```js
+    {
+      id: 1,
+      name: 'Sebastian',
+      friends: [3, 4],
+      links: {
+        house: '/houses/lefkada'
+      }
+    }
+    ```
+  
+    `JSONSerializer` will normalize the JSON payload to the JSON API format that the
+    Ember Data store expects.
+  
+    You can customize how JSONSerializer processes its payload by passing options in
+    the `attrs` hash or by subclassing the `JSONSerializer` and overriding hooks:
+  
+      - To customize how a single record is normalized, use the `normalize` hook.
+      - To customize how `JSONSerializer` normalizes the whole server response, use the
+        `normalizeResponse` hook.
+      - To customize how `JSONSerializer` normalizes a specific response from the server,
+        use one of the many specific `normalizeResponse` hooks.
+      - To customize how `JSONSerializer` normalizes your id, attributes or relationships,
+        use the `extractId`, `extractAttributes` and `extractRelationships` hooks.
+  
+    The `JSONSerializer` normalization process follows these steps:
+  
+      - `normalizeResponse` - entry method to the serializer.
+      - `normalizeCreateRecordResponse` - a `normalizeResponse` for a specific operation is called.
+      - `normalizeSingleResponse`|`normalizeArrayResponse` - for methods like `createRecord` we expect
+        a single record back, while for methods like `findAll` we expect multiple records back.
+      - `normalize` - `normalizeArray` iterates and calls `normalize` for each of its records while `normalizeSingle`
+        calls it once. This is the method you most likely want to subclass.
+      - `extractId` | `extractAttributes` | `extractRelationships` - `normalize` delegates to these methods to
+        turn the record payload into the JSON API format.

+      The `primaryKey` is used when serializing and deserializing
+      data. Ember Data always uses the `id` property to store the id of

+      convention. In these cases it is useful to override the
+      `primaryKey` property to match the `primaryKey` of your external
+      store.
+       Example
+       ```app/serializers/application.js
+      import DS from 'ember-data';
+       export default DS.JSONSerializer.extend({
+        primaryKey: '_id'

+      The `attrs` object can be used to declare a simple mapping between
+      property names on `DS.Model` records and payload keys in the
+      serialized JSON object representing the record. An object with the
+      property `key` can also be used to designate the attribute's key on
+      the response payload.
+       Example
+       ```app/models/person.js
+      import DS from 'ember-data';
+       export default DS.Model.extend({
+        firstName: DS.attr('string'),
+        lastName: DS.attr('string'),
+        occupation: DS.attr('string'),
+        admin: DS.attr('boolean')
+      });
+      ```
+       ```app/serializers/person.js
+      import DS from 'ember-data';
+       export default DS.JSONSerializer.extend({

+          occupation: { key: 'career' }
+        }
+      });
+      ```
+       You can also remove attributes and relationships by setting the `serialize`
+      key to `false` in your mapping object.
+       Example
+       ```app/serializers/person.js
+      import DS from 'ember-data';
+       export default DS.JSONSerializer.extend({
+        attrs: {
+          admin: { serialize: false },
+          occupation: { key: 'career' }
+        }
+      });
+      ```
+       When serialized:
+       ```javascript
+      {
+        "firstName": "Harry",
+        "lastName": "Houdini",
+        "career": "magician"
+      }
+      ```
+       Note that the `admin` is now not included in the payload.
+       Setting `serialize` to `true` enforces serialization for hasMany
+      relationships even if it's neither a many-to-many nor many-to-none
+      relationship.

+      Called when a record is saved in order to convert the
+      record into JSON.
+       By default, it creates a JSON object with a key for
+      each attribute and belongsTo relationship.
+       For example, consider this model:
+       ```app/models/comment.js
+      import DS from 'ember-data';
+       export default DS.Model.extend({
+        title: DS.attr(),
+        body: DS.attr(),
+         author: DS.belongsTo('user')
+      });
+      ```
+       The default serialization would create a JSON object like:
+       ```javascript
+      {
+        "title": "Rails is unagi",
+        "body": "Rails? Omakase? O_O",
+        "author": 12
+      }
+      ```
+       By default, attributes are passed through as-is, unless
+      you specified an attribute type (`DS.attr('date')`). If
+      you specify a transform, the JavaScript value will be
+      serialized when inserted into the JSON hash.
+       By default, belongs-to relationships are converted into
+      IDs when inserted into the JSON hash.
+       ## IDs
+       `serialize` takes an options hash with a single option:
+      `includeId`. If this option is `true`, `serialize` will,
+      by default include the ID in the JSON object it builds.
+       The adapter passes in `includeId: true` when serializing
+      a record for `createRecord`, but not for `updateRecord`.
+       ## Customization
+       Your server may expect a different JSON format than the
+      built-in serialization format.
+       In that case, you can implement `serialize` yourself and
+      return a JSON hash of your choosing.
+       ```app/serializers/post.js
+      import DS from 'ember-data';
+       export default DS.JSONSerializer.extend({
+        serialize(snapshot, options) {
+          var json = {
+            POST_TTL: snapshot.attr('title'),
+            POST_BDY: snapshot.attr('body'),
+            POST_CMS: snapshot.hasMany('comments', { ids: true })
+          };
+           if (options.includeId) {
+            json.POST_ID_ = snapshot.id;
+          }
+           return json;
+        }
+      });
+      ```
+       ## Customizing an App-Wide Serializer
+       If you want to define a serializer for your entire
+      application, you'll probably want to use `eachAttribute`
+      and `eachRelationship` on the record.
+       ```app/serializers/application.js
+      import DS from 'ember-data';
+      import { singularize } from 'ember-inflector';
+       export default DS.JSONSerializer.extend({
+        serialize(snapshot, options) {
+          var json = {};
+           snapshot.eachAttribute(function(name) {
+            json[serverAttributeName(name)] = snapshot.attr(name);
+          });
+           snapshot.eachRelationship(function(name, relationship) {
+            if (relationship.kind === 'hasMany') {
+              json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
+            }
+          });
+           if (options.includeId) {
+            json.ID_ = snapshot.id;
+          }
+           return json;
+        }
+      });
+       function serverAttributeName(attribute) {
+        return attribute.underscore().toUpperCase();
+      }
+       function serverHasManyName(name) {
+        return serverAttributeName(singularize(name)) + "_IDS";
+      }
+      ```
+       This serializer will generate JSON that looks like this:
+       ```javascript
+      {
+        "TITLE": "Rails is omakase",
+        "BODY": "Yep. Omakase.",
+        "COMMENT_IDS": [ 1, 2, 3 ]
+      }
+      ```
+       ## Tweaking the Default JSON
+       If you just want to do some small tweaks on the default JSON,
+      you can call super first and make the tweaks on the returned
+      JSON.
+       ```app/serializers/post.js
+      import DS from 'ember-data';
+       export default DS.JSONSerializer.extend({
+        serialize(snapshot, options) {
+          var json = this._super(...arguments);
+           json.subject = json.title;
+          delete json.title;
+           return json;
+        }
+      });
+      ```
+       @method serialize
+      @param {DS.Snapshot} snapshot
+      @param {Object} options
+      @return {Object} json
+    */
+    serialize: function serialize(snapshot, options) {
+      var _this5 = this;
+
+      var json = {};
+
+      if (options && options.includeId) {
+        var id = snapshot.id;
+
+        if (id) {
+          json[Ember.get(this, 'primaryKey')] = id;
+        }
+      }
+
+      snapshot.eachAttribute(function (key, attribute) {
+        _this5.serializeAttribute(snapshot, json, key, attribute);
+      });
+      snapshot.eachRelationship(function (key, relationship) {
+        if (relationship.kind === 'belongsTo') {
+          _this5.serializeBelongsTo(snapshot, json, relationship);
+        } else if (relationship.kind === 'hasMany') {
+          _this5.serializeHasMany(snapshot, json, relationship);
+        }
+      });
+      return json;
+    },

+      property of the payload object.
+       This serializer expects this `errors` object to be an Array similar
+      to the following, compliant with the JSON-API specification:
+       ```js
+      {
+        "errors": [
+          {
+            "detail": "This username is already taken!",
+            "source": {
+              "pointer": "data/attributes/username"
+            }
+          }, {
+            "detail": "Doesn't look like a valid email.",
+            "source": {
+              "pointer": "data/attributes/email"
+            }
+          }
+        ]
+      }
+      ```
+       The key `detail` provides a textual description of the problem.
+      Alternatively, the key `title` can be used for the same purpose.
+       The nested keys `source.pointer` detail which specific element
+      of the request data was invalid.
+       Note that JSON-API also allows for object-level errors to be placed
+      in an object with pointer `data`, signifying that the problem
+      cannot be traced to a specific attribute:
+       ```javascript
+      {
+        "errors": [
+          {
+            "detail": "Some generic non property error message",
+            "source": {
+              "pointer": "data"
+            }
+          }
+        ]
+      }
+      ```
+       When turn into a `DS.Errors` object, you can read these errors
+      through the property `base`:
+       ```handlebars
+      {{#each model.errors.base as |error|}}
+        <div class="error">
+          {{error.message}}
+        </div>
+      {{/each}}
+      ```
+       Example of alternative implementation, overriding the default
+      behavior to deal with a different format of errors:

+    Normally, applications will use the `RESTSerializer` by implementing
+    the `normalize` method.
+  
+    This allows you to do whatever kind of munging you need and is
+    especially useful if your server is inconsistent and you need to
+    do munging differently for many different kinds of responses.
+  
+    See the `normalize` documentation for more information.
+  
+    ## Across the Board Normalization
+  
+    There are also a number of hooks that you might find useful to define
+    across-the-board rules for your payload. These rules will be useful
+    if your server is consistent, or if you're building an adapter for
+    an infrastructure service, like Firebase, and want to encode service
+    conventions.
+  
+    For example, if all of your keys are underscored and all-caps, but
+    otherwise consistent with the names you use in your models, you
+    can implement across-the-board rules for how to convert an attribute
+    name in your model to a key in your JSON.
+  
+    ```app/serializers/application.js
+    import DS from 'ember-data';
+    import { underscore } from '@ember/string';
+  
+    export default DS.RESTSerializer.extend({
+      keyForAttribute(attr, method) {
+        return underscore(attr).toUpperCase();
+      }
+    });
+    ```
+  
+    You can also implement `keyForRelationship`, which takes the name
+    of the relationship as the first parameter, the kind of
+    relationship (`hasMany` or `belongsTo`) as the second parameter, and
+    the method (`serialize` or `deserialize`) as the third parameter.
+  
+    @class RESTSerializer
+    @namespace DS
+    @extends DS.JSONSerializer
+  */
+  var RESTSerializer = _json.default.extend({
+    /**
+     `keyForPolymorphicType` can be used to define a custom key when
+     serializing and deserializing a polymorphic type. By default, the

+       ```app/serializers/post.js

+    /**
+      Normalizes a part of the JSON payload returned by
+      the server. You should override this method, munge the hash
+      and call super if you have generic normalization to do.
+       It takes the type of the record that is being normalized
+      (as a DS.Model class), the property where the hash was
+      originally found, and the hash to normalize.
+       For example, if you have a payload that looks like this:
+       ```js
+      {
+        "post": {
+          "id": 1,
+          "title": "Rails is omakase",
+          "comments": [ 1, 2 ]
+        },
+        "comments": [{
+          "id": 1,
+          "body": "FIRST"
+        }, {
+          "id": 2,
+          "body": "Rails is unagi"
+        }]
+      }
+      ```
+       The `normalize` method will be called three times:
+       * With `App.Post`, `"posts"` and `{ id: 1, title: "Rails is omakase", ... }`
+      * With `App.Comment`, `"comments"` and `{ id: 1, body: "FIRST" }`
+      * With `App.Comment`, `"comments"` and `{ id: 2, body: "Rails is unagi" }`
+       You can use this method, for example, to normalize underscored keys to camelized
+      or other general-purpose normalizations. You will only need to implement
+      `normalize` and manipulate the payload as desired.
+       For example, if the `IDs` under `"comments"` are provided as `_id` instead of
+      `id`, you can specify how to normalize just the comments:
+       ```app/serializers/post.js
+      import DS from 'ember-data';
+       export default DS.RESTSerializer.extend({
+        normalize(model, hash, prop) {
+          if (prop === 'comments') {
+            hash.id = hash._id;
+            delete hash._id;
+          }
+           return this._super(...arguments);
+        }
+      });
+      ```
+       On each call to the `normalize` method, the third parameter (`prop`) is always
+      one of the keys that were in the original payload or in the result of another
+      normalization as `normalizeResponse`.

+      This method is used to convert each JSON root key in the payload
+      into a modelName that it can use to look up the appropriate model for
+      that part of the payload.
+       For example, your server may send a model name that does not correspond with
+      the name of the model in your app. Let's take a look at an example model,
+      and an example payload:
+       ```app/models/post.js
+      import DS from 'ember-data';
+       export default DS.Model.extend({
+      });
+      ```
+       ```javascript
+        {
+          "blog/post": {
+            "id": "1
+          }
+        }
+      ```
+       Ember Data is going to normalize the payload's root key for the modelName. As a result,
+      it will try to look up the "blog/post" model. Since we don't have a model called "blog/post"
+      (or a file called app/models/blog/post.js in ember-cli), Ember Data will throw an error
+      because it cannot find the "blog/post" model.
+       Since we want to remove this namespace, we can define a serializer for the application that will
+      remove "blog/" from the payload key whenver it's encountered by Ember Data:
+       ```app/serializers/application.js
+      import DS from 'ember-data';
+       export default DS.RESTSerializer.extend({
+        modelNameFromPayloadKey(payloadKey) {
+          if (payloadKey === 'blog/post') {
+            return this._super(payloadKey.replace('blog/', ''));
+          } else {
+           return this._super(payloadKey);
+          }
+        }
+      });
+      ```
+       After refreshing, Ember Data will appropriately look up the "post" model.
+       By default the modelName for a model is its
+      name in dasherized form. This means that a payload key like "blogPost" would be
+      normalized to "blog-post" when Ember Data looks up the model. Usually, Ember Data
+      can use the correct inflection to do this for you. Most of the time, you won't
+      need to override `modelNameFromPayloadKey` for this purpose.
+       @method modelNameFromPayloadKey
+      @param {String} key
+      @return {String} the model's modelName
+    */
+    modelNameFromPayloadKey: function modelNameFromPayloadKey(key) {
+      return (0, _emberInflector.singularize)((0, _private.normalizeModelName)(key));
+    },
+    // SERIALIZE
+
+    /**
+      Called when a record is saved in order to convert the
+      record into JSON.
+       By default, it creates a JSON object with a key for
+      each attribute and belongsTo relationship.
+       For example, consider this model:
+       ```app/models/comment.js
+      import DS from 'ember-data';
+       export default DS.Model.extend({
+        title: DS.attr(),
+        body: DS.attr(),
+         author: DS.belongsTo('user')
+      });
+      ```
+       The default serialization would create a JSON object like:
+       ```js
+      {
+        "title": "Rails is unagi",
+        "body": "Rails? Omakase? O_O",
+        "author": 12
+      }
+      ```
+       By default, attributes are passed through as-is, unless
+      you specified an attribute type (`DS.attr('date')`). If
+      you specify a transform, the JavaScript value will be
+      serialized when inserted into the JSON hash.
+       By default, belongs-to relationships are converted into
+      IDs when inserted into the JSON hash.
+       ## IDs
+       `serialize` takes an options hash with a single option:
+      `includeId`. If this option is `true`, `serialize` will,
+      by default include the ID in the JSON object it builds.
+       The adapter passes in `includeId: true` when serializing
+      a record for `createRecord`, but not for `updateRecord`.
+       ## Customization
+       Your server may expect a different JSON format than the
+      built-in serialization format.
+       In that case, you can implement `serialize` yourself and
+      return a JSON hash of your choosing.
+       ```app/serializers/post.js
+      import DS from 'ember-data';
+       export default DS.RESTSerializer.extend({
+        serialize(snapshot, options) {
+          var json = {
+            POST_TTL: snapshot.attr('title'),
+            POST_BDY: snapshot.attr('body'),
+            POST_CMS: snapshot.hasMany('comments', { ids: true })
+          };
+           if (options.includeId) {
+            json.POST_ID_ = snapshot.id;
+          }
+           return json;
+        }
+      });
+      ```
+       ## Customizing an App-Wide Serializer
+       If you want to define a serializer for your entire
+      application, you'll probably want to use `eachAttribute`
+      and `eachRelationship` on the record.
+       ```app/serializers/application.js
+      import DS from 'ember-data';
+      import { pluralize } from 'ember-inflector';
+       export default DS.RESTSerializer.extend({
+        serialize(snapshot, options) {
+          var json = {};
+           snapshot.eachAttribute(function(name) {
+            json[serverAttributeName(name)] = snapshot.attr(name);
+          });
+           snapshot.eachRelationship(function(name, relationship) {
+            if (relationship.kind === 'hasMany') {
+              json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
+            }
+          });
+           if (options.includeId) {
+            json.ID_ = snapshot.id;
+          }
+           return json;
+        }
+      });
+       function serverAttributeName(attribute) {
+        return attribute.underscore().toUpperCase();
+      }
+       function serverHasManyName(name) {
+        return serverAttributeName(singularize(name)) + "_IDS";
+      }
+      ```
+       This serializer will generate JSON that looks like this:
+       ```js
+      {
+        "TITLE": "Rails is omakase",
+        "BODY": "Yep. Omakase.",
+        "COMMENT_IDS": [ 1, 2, 3 ]
+      }
+      ```
+       ## Tweaking the Default JSON
+       If you just want to do some small tweaks on the default JSON,
+      you can call super first and make the tweaks on the returned
+      JSON.
+       ```app/serializers/post.js
+      import DS from 'ember-data';
+       export default DS.RESTSerializer.extend({
+        serialize(snapshot, options) {
+          var json = this._super(snapshot, options);
+           json.subject = json.title;
+          delete json.title;
+           return json;
+        }
+      });
+      ```
+       @method serialize
+      @param {DS.Snapshot} snapshot
+      @param {Object} options
+      @return {Object} json
+    */
+    serialize: function serialize(snapshot, options) {
+      return this._super.apply(this, arguments);
+    },
+
+    /**
+      You can use this method to customize the root keys serialized into the JSON.
+      The hash property should be modified by reference (possibly using something like _.extend)
+      By default the REST Serializer sends the modelName of a model, which is a camelized
+      version of the name.
+       For example, your server may expect underscored root objects.
+       ```app/serializers/application.js
+      import DS from 'ember-data';
+      import { decamelize } from '@ember/string';
+       export default DS.RESTSerializer.extend({
+        serializeIntoHash(data, type, record, options) {
+          var root = decamelize(type.modelName);
+          data[root] = this.serialize(record, options);
+        }
+      });
+      ```
+       @method serializeIntoHash
+      @param {Object} hash
+      @param {DS.Model} typeClass
+      @param {DS.Snapshot} snapshot
+      @param {Object} options
+    */
+    serializeIntoHash: function serializeIntoHash(hash, typeClass, snapshot, options) {
+      var normalizedRootKey = this.payloadKeyFromModelName(typeClass.modelName);
+      hash[normalizedRootKey] = this.serialize(snapshot, options);
+    },
+
+    /**
+      You can use `payloadKeyFromModelName` to override the root key for an outgoing
+      request. By default, the RESTSerializer returns a camelized version of the
+      model's name.
+       For a model called TacoParty, its `modelName` would be the string `taco-party`. The RESTSerializer
+      will send it to the server with `tacoParty` as the root key in the JSON payload:
+       ```js
+      {
+        "tacoParty": {
+          "id": "1",
+          "location": "Matthew Beale's House"
+        }
+      }
+      ```
+       For example, your server may expect dasherized root objects:
+       ```app/serializers/application.js
+      import DS from 'ember-data';
+      import { dasherize } from '@ember/string';
+       export default DS.RESTSerializer.extend({
+        payloadKeyFromModelName(modelName) {
+          return dasherize(modelName);
+        }
+      });
+      ```
+       Given a `TacoParty` model, calling `save` on it would produce an outgoing
+      request like:
+       ```js
+      {
+        "taco-party": {
+          "id": "1",
+          "location": "Matthew Beale's House"
+        }
+      }
+      ```

+    The `DS.Transform` class is used to serialize and deserialize model
+    attributes when they are saved or loaded from an
+    adapter. Subclassing `DS.Transform` is useful for creating custom
+    attributes. All subclasses of `DS.Transform` must implement a
+    `serialize` and a `deserialize` method.
+  
+    Example
+  
+    ```app/transforms/temperature.js
+    import DS from 'ember-data';
+  
+    // Converts centigrade in the JSON to fahrenheit in the app
+    export default DS.Transform.extend({
+      deserialize(serialized, options) {
+        return (serialized *  1.8) + 32;
+      },
+  
+      serialize(deserialized, options) {
+        return (deserialized - 32) / 1.8;
+      }
+    });
+    ```
+  
+    The options passed into the `DS.attr` function when the attribute is
+    declared on the model is also available in the transform.
+  
+    ```app/models/post.js
+    export default DS.Model.extend({
+      title: DS.attr('string'),
+      markdown: DS.attr('markdown', {
+        markdown: {
+          gfm: false,
+          sanitize: true
+        }
+      })
+    });
+    ```
+  
+    ```app/transforms/markdown.js
+    export default DS.Transform.extend({
+      serialize(deserialized, options) {
+        return deserialized.raw;

+    ## Using BuildURLMixin
+  
+    To use URL building, include the mixin when extending an adapter, and call `buildURL` where needed.
+    The default behaviour is designed for RESTAdapter.

+      }
+    });

+

+    A `DS.AdapterError` is used by an adapter to signal that an error occurred
+    during a request to an external API. It indicates a generic error, and
+    subclasses are used to indicate specific error states. The following
+    subclasses are provided:
+  
+    - `DS.InvalidError`
+    - `DS.TimeoutError`
+    - `DS.AbortError`
+    - `DS.UnauthorizedError`
+    - `DS.ForbiddenError`
+    - `DS.NotFoundError`
+    - `DS.ConflictError`
+    - `DS.ServerError`
+  
+    To create a custom error to signal a specific error state in communicating
+    with an external API, extend the `DS.AdapterError`. For example, if the
+    external API exclusively used HTTP `503 Service Unavailable` to indicate
+    it was closed for maintenance:
+  
+    ```app/adapters/maintenance-error.js
+    import DS from 'ember-data';
+  
+    export default DS.AdapterError.extend({ message: "Down for maintenance." });
+    ```
+  
+    This error would then be returned by an adapter's `handleResponse` method:
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+    import MaintenanceError from './maintenance-error';
+  
+    export default DS.JSONAPIAdapter.extend({
+      handleResponse(status) {

+        }
+  
+        return this._super(...arguments);
+      }
+    });
+    ```
+  
+    And can then be detected in an application and used to send the user to an
+    `under-maintenance` route:
+  
+    ```app/routes/application.js
+    import Route from '@ember/routing/route';

+    A `DS.InvalidError` is used by an adapter to signal the external API
+    was unable to process a request because the content was not
+    semantically correct or meaningful per the API. Usually, this means a
+    record failed some form of server-side validation. When a promise
+    from an adapter is rejected with a `DS.InvalidError` the record will
+    transition to the `invalid` state and the errors will be set to the
+    `errors` property on the record.
+  
+    For Ember Data to correctly map errors to their corresponding
+    properties on the model, Ember Data expects each error to be
+    a valid JSON-API error object with a `source/pointer` that matches
+    the property name. For example, if you had a Post model that
+    looked like this.
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      title: DS.attr('string'),
+      content: DS.attr('string')
+    });
+    ```
+  
+    To show an error from the server related to the `title` and
+    `content` properties your adapter could return a promise that
+    rejects with a `DS.InvalidError` object that looks like this:
+  
+    ```app/adapters/post.js
+    import RSVP from 'RSVP';
+    import DS from 'ember-data';
+  
+    export default DS.RESTAdapter.extend({
+      updateRecord() {
+        // Fictional adapter that always rejects
+        return RSVP.reject(new DS.InvalidError([
+          {
+            detail: 'Must be unique',
+            source: { pointer: '/data/attributes/title' }
+          },
+          {
+            detail: 'Must not be blank',
+            source: { pointer: '/data/attributes/content'}
+          }
+        ]));
+      }
+    });
+    ```
+  
+    Your backend may use different property names for your records the
+    store will attempt to extract and normalize the errors using the
+    serializer's `extractErrors` method before the errors get added to
+    the model. As a result, it is safe for the `InvalidError` to
+    wrap the error payload unaltered.

+  
+    ### Inverses
+  
+    Often, the relationships in Ember Data applications will have
+    an inverse. For example, imagine the following models are
+    defined:
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({

+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      post: DS.belongsTo('post')
+    });
+    ```
+  
+    If you created a new instance of `App.Post` and added
+    a `App.Comment` record to its `comments` has-many
+    relationship, you would expect the comment's `post`
+    property to be set to the post that contained
+    the has-many.
+  
+    We call the record to which a relationship belongs-to the
+    relationship's _owner_.

+       You can then access the metadata via the `meta` property:

+    ## Why does this exist?!?
+  
+    `Ember.Map` was a private API provided by Ember (for quite some time).
+    Unfortunately, ember-data made `Ember.Map` part of its public API surface via
+    documentation blocks.
+  
+    `Ember.Map` will be deprecated and removed from Ember "soon"
+    (https://github.com/emberjs/rfcs/pull/237) and we would like to confirm that
+    Ember Data will work without deprecation before and after that happens.
+  
+    `Ember.Map` differs from native `Map` in a few ways:
+  
+    * `Ember.Map` has custom `copy` and `isEmpty` methods which are not present in native `Map`
+    * `Ember.Map` adds a static `create` method (which simply instantiates itself with `new Ember.Map()`)
+    * `Ember.Map` does not accept constructor arguments
+    * `Ember.Map` does not have:
+      * `@@species`
+      * `@@iterator`
+      * `entries`
+      * `values`
+  
+    This implementation adds a deprecated backwards compatibility for:
+  
+    * `copy`
+    * `isEmpty`
+  
+    ## Why is this written this way?!?

+    You can retrieve models from the store in several ways. To retrieve a record
+    for a specific id, use `DS.Store`'s `findRecord()` method:
+  
+    ```javascript
+    store.findRecord('person', 123).then(function (person) {
+    });
+    ```
+  
+    By default, the store will talk to your backend using a standard
+    REST mechanism. You can customize how the store talks to your
+    backend by specifying a custom adapter:
+  
+    ```app/adapters/application.js
+    import DS from 'ember-data';
+  
+    export default DS.Adapter.extend({
+    });
+    ```
+  
+    You can learn more about writing a custom adapter by reading the `DS.Adapter`
+    documentation.
+  
+    ### Store createRecord() vs. push() vs. pushPayload()
+  
+    The store provides multiple ways to create new record objects. They have
+    some subtle differences in their use which are detailed below:
+  
+    [createRecord](#method_createRecord) is used for creating new
+    records on the client side. This will return a new record in the
+    `created.uncommitted` state. In order to persist this record to the
+    backend, you will need to call `record.save()`.
+  
+    [push](#method_push) is used to notify Ember Data's store of new or
+    updated records that exist in the backend. This will return a record
+    in the `loaded.saved` state. The primary use-case for `store#push` is
+    to notify Ember Data about record updates (full or partial) that happen
+    outside of the normal adapter methods (for example
+    [SSE](http://dev.w3.org/html5/eventsource/) or [Web
+    Sockets](http://www.w3.org/TR/2009/WD-websockets-20091222/)).
+  
+    [pushPayload](#method_pushPayload) is a convenience wrapper for
+    `store#push` that will deserialize payloads if the
+    Serializer implements a `pushPayload` method.
+  
+    Note: When creating a new record using any of the above methods
+    Ember Data will update `DS.RecordArray`s such as those returned by
+    `store#peekAll()` or `store#findAll()`. This means any
+    data bindings or computed properties that depend on the RecordArray
+    will automatically be synced to include the new or updated record
+    values.

+      object for a given type and `id`.
+       The `findRecord` method will always return a **promise** that will be
+      resolved with the record.
+       Example
+       ```app/routes/post.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model(params) {
+          return this.store.findRecord('post', params.post_id);
+        }
+      });
+      ```
+       If the record is not yet available, the store will ask the adapter's `find`
+      method to find the necessary data. If the record is already present in the
+      store, it depends on the reload behavior _when_ the returned promise
+      resolves.
+       ### Preloading
+       You can optionally `preload` specific attributes and relationships that you know of
+      by passing them via the passed `options`.
+       For example, if your Ember route looks like `/posts/1/comments/2` and your API route
+      for the comment also looks like `/posts/1/comments/2` if you want to fetch the comment
+      without fetching the post you can pass in the post to the `findRecord` call:
+       ```javascript
+      store.findRecord('comment', 2, { preload: { post: 1 } });
+      ```
+       If you have access to the post model you can also pass the model itself:
+       ```javascript
+      store.findRecord('post', 1).then(function (myPostModel) {
+        store.findRecord('comment', 2, { post: myPostModel });
+      });
+      ```
+       ### Reloading
+       The reload behavior is configured either via the passed `options` hash or
+      the result of the adapter's `shouldReloadRecord`.
+       If `{ reload: true }` is passed or `adapter.shouldReloadRecord` evaluates
+      to `true`, then the returned promise resolves once the adapter returns
+      data, regardless if the requested record is already in the store:
+       ```js
+      store.push({
+        data: {
+          id: 1,
+          type: 'post',
+          revision: 1
+        }
+      });
+       // adapter#findRecord resolves with
+      // [
+      //   {
+      //     id: 1,
+      //     type: 'post',
+      //     revision: 2
+      //   }
+      // ]
+      store.findRecord('post', 1, { reload: true }).then(function(post) {
+        post.get('revision'); // 2
+      });
+      ```
+       If no reload is indicated via the abovementioned ways, then the promise
+      immediately resolves with the cached version in the store.
+       ### Background Reloading
+       Optionally, if `adapter.shouldBackgroundReloadRecord` evaluates to `true`,
+      then a background reload is started, which updates the records' data, once
+      it is available:
+       ```js
+      // app/adapters/post.js
+      import ApplicationAdapter from "./application";
+       export default ApplicationAdapter.extend({
+        shouldReloadRecord(store, snapshot) {
+          return false;
+        },
+         shouldBackgroundReloadRecord(store, snapshot) {
+          return true;
+        }
+      });
+       // ...
+       store.push({
+        data: {
+          id: 1,
+          type: 'post',
+          revision: 1
+        }
+      });
+       let blogPost = store.findRecord('post', 1).then(function(post) {
+        post.get('revision'); // 1
+      });
+       // later, once adapter#findRecord resolved with
+      // [
+      //   {
+      //     id: 1,
+      //     type: 'post',
+      //     revision: 2
+      //   }
+      // ]
+       blogPost.get('revision'); // 2
+      ```
+       If you would like to force or prevent background reloading, you can set a
+      boolean value for `backgroundReload` in the options object for
+      `findRecord`.
+       ```app/routes/post/edit.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model(params) {
+          return this.store.findRecord('post', params.post_id, { backgroundReload: false });
+        }
+      });
+      ```
+       If you pass an object on the `adapterOptions` property of the options
+      argument it will be passed to you adapter via the snapshot
+       ```app/routes/post/edit.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model(params) {
+          return this.store.findRecord('post', params.post_id, {
+            adapterOptions: { subscribe: false }
+          });
+        }
+      });
+      ```
+       ```app/adapters/post.js
+      import MyCustomAdapter from './custom-adapter';
+       export default MyCustomAdapter.extend({
+        findRecord(store, type, id, snapshot) {
+          if (snapshot.adapterOptions.subscribe) {
+            // ...
+          }
+          // ...
+        }
+      });
+      ```
+       See [peekRecord](#method_peekRecord) to get the cached version of a record.
+       ### Retrieving Related Model Records
+       If you use an adapter such as Ember's default
+      [`JSONAPIAdapter`](https://emberjs.com/api/data/classes/DS.JSONAPIAdapter.html)
+      that supports the [JSON API specification](http://jsonapi.org/) and if your server
+      endpoint supports the use of an
+      ['include' query parameter](http://jsonapi.org/format/#fetching-includes),
+      you can use `findRecord()` to automatically retrieve additional records related to
+      the one you request by supplying an `include` parameter in the `options` object.
+       For example, given a `post` model that has a `hasMany` relationship with a `comment`
+      model, when we retrieve a specific post we can have the server also return that post's
+      comments in the same request:
+       ```app/routes/post.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model(params) {
+          return this.store.findRecord('post', params.post_id, { include: 'comments' });
+        }
+      });
+       ```
+      In this case, the post's comments would then be available in your template as
+      `model.comments`.
+       Multiple relationships can be requested using an `include` parameter consisting of a
+      comma-separated list (without white-space) while nested relationships can be specified

+       This method can be used when it is certain that the server will return a
+      single object for the primary data.
+       Each time this method is called a new request is made through the adapter.
+       Let's assume our API provides an endpoint for the currently logged in user
+      via:
+       ```
+      // GET /api/current_user
+      {
+        user: {
+          id: 1234,
+          username: 'admin'
+        }
+      }
+      ```
+       Since the specific `id` of the `user` is not known beforehand, we can use
+      `queryRecord` to get the user:
+       ```javascript
+      store.queryRecord('user', {}).then(function(user) {
+        let username = user.get('username');
+        console.log(`Currently logged in as ${username}`);
+      });
+      ```
+       The request is made through the adapters' `queryRecord`:
+       ```app/adapters/user.js
+      import $ from 'jquery';
+      import DS from 'ember-data';
+       export default DS.Adapter.extend({
+        queryRecord(modelName, query) {
+          return $.getJSON('/api/current_user');
+        }
+      });
+      ```
+       Note: the primary use case for `store.queryRecord` is when a single record
+      is queried and the `id` is not known beforehand. In all other cases
+      `store.query` and using the first item of the array is likely the preferred
+      way:
+       ```
+      // GET /users?username=unique
+      {
+        data: [{
+          id: 1234,
+          type: 'user',
+          attributes: {
+            username: "unique"
+          }
+        }]
+      }
+      ```
+       ```javascript

+      }).then(function(user) {
+        let id = user.get('id');
+      });
+      ```
+       This method returns a promise, which resolves with the found record.
+       If the adapter returns no data for the primary data of the payload, then
+      `queryRecord` resolves with `null`:
+       ```
+      // GET /users?username=unique

+        authors.getEach('id'); // ['first', 'second']
+      });
+      ```
+       If no reload is indicated via the abovementioned ways, then the promise
+      immediately resolves with all the records currently loaded in the store.
+       ### Background Reloading
+       Optionally, if `adapter.shouldBackgroundReloadAll` evaluates to `true`,
+      then a background reload is started. Once this resolves, the array with
+      which the promise resolves, is updated automatically so it contains all the
+      records in the store:
+       ```app/adapters/application.js
+      import DS from 'ember-data';
+      export default DS.Adapter.extend({
+        shouldReloadAll(store, snapshotsArray) {
+          return false;
+        },
+         shouldBackgroundReloadAll(store, snapshotsArray) {
+          return true;
+        }
+      });
+       // ...
+       store.push({
+        data: {
+          id: 'first',
+          type: 'author'
+        }
+      });
+       let allAuthors;
+      store.findAll('author').then(function(authors) {
+        authors.getEach('id'); // ['first']
+         allAuthors = authors;
+      });
+       // later, once adapter#findAll resolved with
+      // [
+      //   {
+      //     id: 'second',
+      //     type: 'author'
+      //   }
+      // ]
+       allAuthors.getEach('id'); // ['first', 'second']
+      ```
+       If you would like to force or prevent background reloading, you can set a
+      boolean value for `backgroundReload` in the options object for
+      `findAll`.
+       ```app/routes/post/edit.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model() {
+          return this.store.findAll('post', { backgroundReload: false });
+        }
+      });
+      ```
+       If you pass an object on the `adapterOptions` property of the options
+      argument it will be passed to you adapter via the `snapshotRecordArray`
+       ```app/routes/posts.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model(params) {
+          return this.store.findAll('post', {
+            adapterOptions: { subscribe: false }
+          });
+        }
+      });
+      ```
+       ```app/adapters/post.js
+      import MyCustomAdapter from './custom-adapter';
+       export default MyCustomAdapter.extend({
+        findAll(store, type, sinceToken, snapshotRecordArray) {
+          if (snapshotRecordArray.adapterOptions.subscribe) {
+            // ...
+          }
+          // ...
+        }
+      });
+      ```
+       See [peekAll](#method_peekAll) to get an array of current records in the
+      store, without waiting until a reload is finished.
+       ### Retrieving Related Model Records
+       If you use an adapter such as Ember's default
+      [`JSONAPIAdapter`](https://emberjs.com/api/data/classes/DS.JSONAPIAdapter.html)
+      that supports the [JSON API specification](http://jsonapi.org/) and if your server
+      endpoint supports the use of an
+      ['include' query parameter](http://jsonapi.org/format/#fetching-includes),
+      you can use `findAll()` to automatically retrieve additional records related to
+      those requested by supplying an `include` parameter in the `options` object.
+       For example, given a `post` model that has a `hasMany` relationship with a `comment`
+      model, when we retrieve all of the post records we can have the server also return
+      all of the posts' comments in the same request:
+       ```app/routes/posts.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model() {
+          return this.store.findAll('post', { include: 'comments' });
+        }
+      });
+       ```
+      Multiple relationships can be requested using an `include` parameter consisting of a
+      comma-separated list (without white-space) while nested relationships can be specified
+      using a dot-separated sequence of relationship names. So to request both the posts'
+      comments and the authors of those comments the request would look like this:
+       ```app/routes/posts.js
+      import Route from '@ember/routing/route';
+       export default Route.extend({
+        model() {
+          return this.store.findAll('post', { include: 'comments,comments.author' });
+        }
+      });
+       ```
+       See [query](#method_query) to only get a subset of records from the server.

+      - record's `type` should always be in singular, dasherized form
+      - members (properties) should be camelCased
+       [Your primary data should be wrapped inside `data` property](http://jsonapi.org/format/#document-top-level):
+       ```js
+      store.push({
+        data: {
+          // primary data for single record of type `Person`
+          id: '1',

+      ```
+       [Demo.](http://ember-twiddle.com/fb99f18cd3b4d3e2a4c7)
+       `data` property can also hold an array (of records):
+       ```js
+      store.push({
+        data: [
+          // an array of records
+          {

+       There are some typical properties for `JSONAPI` payload:
+      * `id` - mandatory, unique record's key
+      * `type` - mandatory string which matches `model`'s dasherized name in singular form
+      * `attributes` - object which holds data for record attributes - `DS.attr`'s declared in model
+      * `relationships` - object which must contain any of the following properties under each relationships' respective key (example path is `relationships.achievements.data`):
+        - [`links`](http://jsonapi.org/format/#document-links)
+        - [`data`](http://jsonapi.org/format/#document-resource-object-linkage) - place for primary data
+        - [`meta`](http://jsonapi.org/format/#document-meta) - object which contains meta-information about relationship
+       For this model:
+       ```app/models/person.js
+      import DS from 'ember-data';
+       export default DS.Model.extend({
+        firstName: DS.attr('string'),
+        lastName: DS.attr('string'),
+         children: DS.hasMany('person')
+      });
+      ```
+       To represent the children as IDs:
+       ```js
+      {
+        data: {
+          id: '1',
+          type: 'person',

+              ]
+            }
+          }
+        }
+      }
+      ```
+       [Demo.](http://ember-twiddle.com/343e1735e034091f5bde)
+       To represent the children relationship as a URL:
+       ```js
+      {
+        data: {
+          id: '1',
+          type: 'person',

+            }
+          }
+        }
+      }
+      ```
+       If you're streaming data or implementing an adapter, make sure
+      that you have converted the incoming data into this form. The
+      store's [normalize](#method_normalize) method is a convenience
+      helper for converting a json payload into the form Ember Data

+    Holds validation errors for a given record, organized by attribute names.
+  
+    Every `DS.Model` has an `errors` property that is an instance of
+    `DS.Errors`. This can be used to display validation error
+    messages returned from the server when a `record.save()` rejects.
+  
+    For Example, if you had a `User` model that looked like this:
+  
+    ```app/models/user.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      username: DS.attr('string'),
+      email: DS.attr('string')
+    });
+    ```
+    And you attempted to save a record that did not validate on the backend:
+  
+    ```javascript
+    let user = store.createRecord('user', {
+      username: 'tomster',
+      email: 'invalidEmail'
+    });
+    user.save();
+    ```
+  
+    Your backend would be expected to return an error response that described
+    the problem, so that error messages can be generated on the app.
+  
+    API responses will be translated into instances of `DS.Errors` differently,
+    depending on the specific combination of adapter and serializer used. You
+    may want to check the documentation or the source code of the libraries
+    that you are using, to know how they expect errors to be communicated.
+  
+    Errors can be displayed to the user by accessing their property name
+    to get an array of all the error objects for that property. Each
+    error object is a JavaScript object with two keys:
+  
+    - `message` A string containing the error message from the backend
+    - `attribute` The name of the property associated with this error message
+  
+    ```handlebars
+    <label>Username: {{input value=username}} </label>
+    {{#each model.errors.username as |error|}}
+      <div class="error">
+        {{error.message}}
+      </div>
+    {{/each}}
+  
+    <label>Email: {{input value=email}} </label>
+    {{#each model.errors.email as |error|}}
+      <div class="error">
+        {{error.message}}
+      </div>
+    {{/each}}
+    ```
+  
+    You can also access the special `messages` property on the error
+    object to get an array of all the error strings.
+  
+    ```handlebars
+    {{#each model.errors.messages as |message|}}
+      <div class="error">
+        {{message}}
+      </div>

+  */
+
+  /**
+    ### State
+  
+    Each record has a `currentState` property that explicitly tracks what
+    state a record is in at any given time. For instance, if a record is
+    newly created and has not yet been sent to the adapter to be saved,
+    it would be in the `root.loaded.created.uncommitted` state.  If a
+    record has had local modifications made to it that are in the
+    process of being saved, the record would be in the
+    `root.loaded.updated.inFlight` state. (This state path will be
+    explained in more detail below.)
+  
+    Events are sent by the record or its store to the record's
+    `currentState` property. How the state reacts to these events is
+    dependent on which state it is in. In some states, certain events
+    will be invalid and will cause an exception to be raised.
+  
+    States are hierarchical and every state is a sub-state of the
+    `RootState`. For example, a record can be in the
+    `root.deleted.uncommitted` state then transitions into the
+    `root.deleted.inFlight` state. If a child state does not implement
+    an event handler, the state manager will attempt to invoke the event
+    on all parent states until the root state is reached. The state
+    hierarchy of a record is described in terms of a path string. You
+    can determine a record's current state by getting the state's
+    `stateName` property:
+  
+    ```javascript
+    record.get('currentState.stateName');
+    //=> "root.created.uncommitted"
+     ```
+  
+    The hierarchy of valid states that ship with ember data looks like
+    this:
+  
+    ```text
+    * root
+      * deleted
+        * saved
+        * uncommitted
+        * inFlight
+      * empty
+      * loaded
+        * created
+          * uncommitted
+          * inFlight
+        * saved
+        * updated
+          * uncommitted
+          * inFlight
+      * loading
+    ```
+  
+    The `DS.Model` states are themselves stateless. What that means is
+    that, the hierarchical states that each of *those* points to is a
+    shared data structure. For performance reasons, instead of each
+    record getting its own copy of the hierarchy of states, each record
+    points to this global, immutable shared instance. How does a state
+    know which record it should be acting on? We pass the record
+    instance into the state's event handlers as the first argument.
+  
+    The record passed as the first parameter is where you should stash
+    state about the record if needed; you should never store data on the state
+    object itself.
+  
+    ### Events and Flags
+  
+    A state may implement zero or more events and flags.
+  
+    #### Events
+  
+    Events are named functions that are invoked when sent to a record. The
+    record will first look for a method with the given name on the
+    current state. If no method is found, it will search the current
+    state's parent, and then its grandparent, and so on until reaching
+    the top of the hierarchy. If the root is reached without an event
+    handler being found, an exception will be raised. This can be very
+    helpful when debugging new features.
+  
+    Here's an example implementation of a state with a `myEvent` event handler:
+  
+    ```javascript
+    aState: DS.State.create({
+      myEvent: function(manager, param) {
+        console.log("Received myEvent with", param);
+      }
+    })
+    ```
+  
+    To trigger this event:
+  
+    ```javascript
+    record.send('myEvent', 'foo');
+    //=> "Received myEvent with foo"
+    ```
+  
+    Note that an optional parameter can be sent to a record's `send()` method,
+    which will be passed as the second parameter to the event handler.
+  
+    Events should transition to a different state if appropriate. This can be
+    done by calling the record's `transitionTo()` method with a path to the
+    desired state. The state manager will attempt to resolve the state path
+    relative to the current state. If no state is found at that path, it will
+    attempt to resolve it relative to the current state's parent, and then its
+    parent, and so on until the root is reached. For example, imagine a hierarchy
+    like this:
+  
+        * created
+          * uncommitted <-- currentState
+          * inFlight
+        * updated
+          * inFlight
+  
+    If we are currently in the `uncommitted` state, calling
+    `transitionTo('inFlight')` would transition to the `created.inFlight` state,
+    while calling `transitionTo('updated.inFlight')` would transition to
+    the `updated.inFlight` state.
+  
+    Remember that *only events* should ever cause a state transition. You should
+    never call `transitionTo()` from outside a state's event handler. If you are
+    tempted to do so, create a new event and send that to the state manager.
+  
+    #### Flags
+  
+    Flags are Boolean values that can be used to introspect a record's current
+    state in a more user-friendly way than examining its state path. For example,
+    instead of doing this:
+  
+    ```javascript
+    var statePath = record.get('stateManager.currentPath');
+    if (statePath === 'created.inFlight') {
+      doSomething();
+    }
+    ```
+  
+    You can say:
+  
+    ```javascript
+    if (record.get('isNew') && record.get('isSaving')) {
+      doSomething();
+    }
+    ```
+  
+    If your state does not set a value for a given flag, the value will
+    be inherited from its parent (or the first place in the state hierarchy
+    where it is defined).
+  
+    The current set of flags are defined below. If you want to add a new flag,
+    in addition to the area below, you will also need to declare it in the
+    `DS.Model` class.

+  // Each state has a boolean value for all of the following flags:
+  //
+  // * isLoaded: The record has a populated `data` property. When a
+  //   record is loaded via `store.find`, `isLoaded` is false
+  //   until the adapter sets it. When a record is created locally,
+  //   its `isLoaded` property is always true.
+  // * isDirty: The record has local changes that have not yet been
+  //   saved by the adapter. This includes records that have been
+  //   created (but not yet saved) or deleted.
+  // * isSaving: The record has been committed, but
+  //   the adapter has not yet acknowledged that the changes have
+  //   been persisted to the backend.
+  // * isDeleted: The record was marked for deletion. When `isDeleted`
+  //   is true and `isDirty` is true, the record is deleted locally
+  //   but the deletion was not yet persisted. When `isSaving` is
+  //   true, the change is in-flight. When both `isDirty` and
+  //   `isSaving` are false, the change has persisted.
+  // * isNew: The record was created on the client and the adapter
+  //   did not yet report that it was successfully saved.
+  // * isValid: The adapter did not report any server-side validation
+  //   failures.
+  // The dirty state is a abstract state whose functionality is
+  // shared between the `created` and `updated` states.
+  //
+  // The deleted state shares the `isDirty` flag with the
+  // subclasses of `DirtyState`, but with a very different
+  // implementation.
+  //
+  // Dirty states have three child states:
+  //
+  // `uncommitted`: the store has not yet handed off the record
+  //   to be saved.
+  // `inFlight`: the store has handed off the record to be saved,

+    `DS.belongsTo` is used to define One-To-One and One-To-Many
+    relationships on a [DS.Model](/api/data/classes/DS.Model.html).
+  
+  
+    `DS.belongsTo` takes an optional hash as a second parameter, currently
+    supported options are:
+  
+    - `async`: A boolean value used to explicitly declare this to be an async relationship.
+    - `inverse`: A string used to identify the inverse property on a
+      related model in a One-To-Many relationship. See [Explicit Inverses](#toc_explicit-inverses)
+  
+    #### One-To-One
+    To declare a one-to-one relationship between two models, use
+    `DS.belongsTo`:
+  
+    ```app/models/user.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      profile: DS.belongsTo('profile')
+    });
+    ```
+  
+    ```app/models/profile.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      user: DS.belongsTo('user')
+    });
+    ```
+  
+    #### One-To-Many
+    To declare a one-to-many relationship between two models, use
+    `DS.belongsTo` in combination with `DS.hasMany`, like this:
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      comments: DS.hasMany('comment')
+    });
+    ```
+  
+    ```app/models/comment.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      post: DS.belongsTo('post')
+    });
+    ```
+  
+    You can avoid passing a string as the first parameter. In that case Ember Data
+    will infer the type from the key name.
+  
+    ```app/models/comment.js
+    import DS from 'ember-data';

+    `DS.hasMany` is used to define One-To-Many and Many-To-Many

+    - `inverse`: A string used to identify the inverse property on a related model.
+

+    `DS.belongsTo` in combination with `DS.hasMany`, like this:
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      comments: DS.hasMany('comment')
+    });

+  
+    export default DS.Model.extend({
+      post: DS.belongsTo('post')
+    });
+    ```
+  
+    #### Many-To-Many
+    To declare a many-to-many relationship between two models, use
+    `DS.hasMany`:
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      tags: DS.hasMany('tag')
+    });
+    ```
+  
+    ```app/models/tag.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      posts: DS.hasMany('post')
+    });
+    ```
+  
+    You can avoid passing a string as the first parameter. In that case Ember Data
+    will infer the type from the singularized key name.
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      tags: DS.hasMany()
+    });
+    ```
+  
+    will lookup for a Tag type.
+  
+    #### Explicit Inverses
+  
+    Ember Data will do its best to discover which relationships map to
+    one another. In the one-to-many code above, for example, Ember Data
+    can figure out that changing the `comments` relationship should update
+    the `post` relationship on the inverse because post is the only
+    relationship to that model.
+  
+    However, sometimes you may have multiple `belongsTo`/`hasMany` for the
+    same type. You can specify which property on the related model is
+    the inverse using `DS.hasMany`'s `inverse` option:
+  
+    ```app/models/comment.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      onePost: DS.belongsTo('post'),
+      twoPost: DS.belongsTo('post'),
+      redPost: DS.belongsTo('post'),
+      bluePost: DS.belongsTo('post')
+    });
+    ```
+  
+    ```app/models/post.js
+    import DS from 'ember-data';
+  
+    export default DS.Model.extend({
+      comments: DS.hasMany('comment', {
+        inverse: 'redPost'
+      })
+    });
+    ```
+  
+    You can also specify an inverse on a `belongsTo`, which works how
+    you'd expect.

+    this code will automatically instantiate it and make it available on the
+    router.
+  
+    Additionally, after an application's controllers have been injected, they will
+    each have the store made available to them.
+  
+    For example, imagine an Ember.js application with the following classes:
+  
+    ```app/services/store.js
+    import DS from 'ember-data';
+  
+    export default DS.Store.extend({

+  
+    export default Controller.extend({
+      // ...
+    });
+  
+    When the application is initialized, `ApplicationStore` will automatically be
+    instantiated, and the instance of `PostsController` will have its `store`
+    property set to that instance.
+  
+    Note that this code will only be run if the `ember-application` package is
+    loaded. If Ember Data is being used in an environment other than a
+    typical application (e.g., node.js where only `ember-runtime` is available),
+    this code will be ignored.
