  This code registers an injection for Ember.Application.

  If an Ember.js developer defines a subclass of DS.Store on their application,
  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.Store = DS.Store.extend({
    adapter: 'custom'
  });

  App.PostsController = Ember.ArrayController.extend({
    // ...
  });

  When the application is initialized, `App.Store` will automatically be
  instantiated, and the instance of `App.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.

  A ManyArray is a RecordArray that represents the contents of a has-many

  The ManyArray is instantiated lazily the first time the relationship is

  Often, the relationships in Ember Data applications will have
  an inverse. For example, imagine the following models are

  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.

/**
  The Mappable mixin is designed for classes that would like to
  behave as a map for configuration purposes.

  For example, the DS.Adapter class can behave like a map, with
  more semantic API, via the `map` API:

    DS.Adapter.map('App.Person', { firstName: { key: 'FIRST' } });

  Class configuration via a map-like API has a few common requirements
  that differentiate it from the standard Ember.Map implementation.

  First, values often are provided as strings that should be normalized
  into classes the first time the configuration options are used.

  Second, the values configured on parent classes should also be taken
  into account.

  Finally, setting the value of a key sometimes should merge with the
  previous value, rather than replacing it.

  This mixin provides a instance method, `createInstanceMapFor`, that
  will reify all of the configuration options set on an instance's
  constructor and provide it for the instance to use.

  Classes can implement certain hooks that allow them to customize
  the requirements listed above:

  * `resolveMapConflict` - called when a value is set for an existing
    value
  * `transformMapKey` - allows a key name (for example, a global path
    to a class) to be normalized
  * `transformMapValue` - allows a value (for example, a class that
    should be instantiated) to be normalized

  Classes that implement this mixin should also implement a class
  method built using the `generateMapFunctionFor` method:

    DS.Adapter.reopenClass({
      map: DS.Mappable.generateMapFunctionFor('attributes', function(key, newValue, map) {
        var existingValue = map.get(key);

        for (var prop in newValue) {
          if (!newValue.hasOwnProperty(prop)) { continue; }
          existingValue[prop] = newValue[prop];
        }
      })
    });

  The function passed to `generateMapFunctionFor` is invoked every time a
  new value is added to the map.

//   The variables in this file are consistently named according to the following

//     before being used internally.
//   * +clientId+ means a transient numerical identifier generated at runtime by
//     the data store. It is important primarily because newly created objects may
//     not yet have an externally generated id.
//   * +reference+ means a record reference object, which holds metadata about a
//     record, even if it has not yet been fully materialized.
//   * +type+ means a subclass of DS.Model.

// Used by the store to normalize IDs entering the store.  Despite the fact
// that developers may provide IDs as numbers (e.g., `store.find(Person, 1)`),
// it is important that internally we use strings, since IDs may be serialized
// and lose type information.  For example, Ember's router may put a record's

/**
  The store contains all of the data for records loaded from the server.
  It is also responsible for creating instances of DS.Model that wrap
  the individual data for a record, so that they can be bound to in your
  Handlebars templates.

  Define your application's store like this:

       MyApp.Store = DS.Store.extend();

  Most Ember.js applications will only have a single `DS.Store` that is
  automatically created by their `Ember.Application`.

  You can retrieve models from the store in several ways. To retrieve a record
  for a specific id, use `DS.Model`'s `find()` method:

       var person = App.Person.find(123);

  If your application has multiple `DS.Store` instances (an unusual case), you can
  specify which store should be used:

      var person = store.find(App.Person, 123);

  In general, you should retrieve models using the methods on `DS.Model`; you should
  rarely need to interact with the store directly.

  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:

       MyApp.store = DS.Store.create({
         adapter: 'MyApp.CustomAdapter'
       });

  You can learn more about writing a custom adapter by reading the `DS.Adapter`
  documentation.

  This file encapsulates the various states that a record can transition
  through during its lifecycle.

  ### State Manager

  A record's state manager 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
  `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 `updated.inFlight` state. (These state paths will be explained
  in more detail below.)

  Events are sent by the record or its store to the record's state manager.
  How the state manager 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. For example, a record can be in the
  `deleted.start` state, then transition into the `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 its manager's
  current state path:

      record.get('stateManager.currentPath');
      //=> "created.uncommitted"

  The `DS.Model` states are themselves stateless. What we mean is that,
  though each instance of a record also has a unique instance of a
  `DS.StateManager`, 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 state
  manager points to this global, immutable shared instance. How does a
  state know which record it should be acting on?  We pass a reference to
  the current state manager as the first parameter to every method invoked
  on a state.

  The state manager 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. If you need access to the record being acted on, you can
  retrieve the state manager's `record` property. For example, if you had
  an event handler `myEvent`:

      myEvent: function(manager) {
        var record = manager.get('record');
        record.doSomething();
      }

  For more information about state managers in general, see the Ember.js
  documentation on `Ember.StateManager`.

  ### Events, Flags, and Transitions

  A state may implement zero or more events, flags, or transitions.

  #### Events

  Events are named functions that are invoked when sent to a record. The
  state manager 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:

      aState: DS.State.create({
        myEvent: function(manager, param) {
          console.log("Received myEvent with "+param);
        }
      })

  To trigger this event:

      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 state manager'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
        * start <-- currentState
        * inFlight
      * updated
        * inFlight

  If we are currently in the `start` 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:

      var statePath = record.get('stateManager.currentPath');
      if (statePath === 'created.inFlight') {
        doSomething();
      }

  You can say:

      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.

  #### Transitions

  Transitions are like event handlers but are called automatically upon
  entering or exiting a state. To implement a transition, just call a method
  either `enter` or `exit`:

      myState: DS.State.create({
        // Gets called automatically when entering
        // this state.
        enter: function(manager) {
          console.log("Entered myState");
        }
      })

  Note that enter and exit events are called once per transition. If the
  current state changes, but changes to another child state of the parent,
  the transition event on the parent will not be triggered.

// Implementation notes:
//
// 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.
// * isError: The adapter reported that it was unable to save
//   local changes to the backend. This may also result in the
//   record having its `isValid` property become false if the
//   adapter reported that server-side validations failed.
// * isNew: The record was created on the client and the adapter
//   did not yet report that it was successfully saved.
// * isValid: No client-side validations have failed and 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.

/**
  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.

  ### Creating an Adapter

  First, create a new subclass of `DS.Adapter`:

      App.MyAdapter = DS.Adapter.extend({
        // ...your code here
      });

  To tell your store which adapter to use, set its `adapter` property:

      App.store = DS.Store.create({
        adapter: App.MyAdapter.create()
      });

  `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:

    * `find()`
    * `createRecord()`
    * `updateRecord()`
    * `deleteRecord()`

  To improve the network performance of your application, you can optimize
  your adapter by overriding these lower-level methods:

    * `findMany()`
    * `createRecords()`
    * `updateRecords()`
    * `deleteRecords()`
    * `commit()`

  For an example implementation, see `DS.RESTAdapter`, the
  included REST adapter.

  @class Adapter
  @namespace DS
  @extends Ember.Object
  @uses DS._Mappable
*/

DS.Adapter = Ember.Object.extend(DS._Mappable, {

  /**
    The `find()` method is invoked when the store is asked for a record that
    has not previously been loaded. In response to `find()` being called, you
    should query your persistence layer for a record with the given ID. Once
    found, you can asynchronously call the store's `push()` method to push
    the record into the store.

    Here is an example `find` implementation:

        find: function(store, type, id) {
          var url = type.url;
          url = url.fmt(id);

          jQuery.getJSON(url, function(data) {
              // data is a hash of key/value pairs. If your server returns a
              // root, simply do something like:
              // store.push(type, id, data.person)
              store.push(type, id, data);

    Most traditional REST-like HTTP APIs will not use this method. Instead, the ID
    of the record will be set by the server, and your adapter will update the store
    with the new ID when it calls `didCreateRecord()`. Only implement this method if
    you intend to generate record IDs on the client-side.

    The `generateIdForRecord()` method will be invoked with the requesting store as

/**
  Normally, applications will use the `RESTSerializer` by implementing
  the `normalize` method and individual normalizations under
  `normalizeHash`.

  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 defined
  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 Parse, 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.

  ```js
  App.ApplicationSerializer = DS.RESTSerializer.extend({
    keyForAttribute: function(attr) {
      return Ember.String.underscore(attr).toUpperCase();
    }
  });
  ```

  You can also implement `keyForRelationship`, which takes the name
  of the relationship as the first parameter, and the kind of
  relationship (`hasMany` or `belongsTo`) as the second parameter.

  @class RESTSerializer
  @namespace DS
  @extends DS.JSONSerializer
*/
DS.RESTSerializer = DS.JSONSerializer.extend({
  /**
    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.

    If you want to do normalizations specific to some part of the payload, you
    can specify those under `normalizeHash`.

    For example, if the `IDs` under `"comments"` are provided as `_id` instead of
    `id`, you can specify how to normalize just the comments:

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      normalizeHash: {
        comments: function(hash) {
          hash.id = hash._id;
          delete hash._id;
          return hash;
        }
      }
    });
    ```

    The key under `normalizeHash` is just the original key that was in the original
    payload.

    It is your opportunity to clean up the server's response into the normalized
    form expected by Ember Data.

    If you want, you can just restructure the top-level of your payload, and
    do more fine-grained normalization in the `normalize` method.

    For example, if you have a payload like this in response to a request for
    post 1:

    ```js
    {
      "id": 1,
      "title": "Rails is omakase",

      "_embedded": {
        "comment": [{

          "comment_title": "Rails is unagi"
        }]
      }
    }
    ```

    You could implement a serializer that looks like this to get your payload
    into shape:

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      // First, restructure the top-level so it's organized by type
      extractSingle: function(store, type, payload, id, requestType) {
        var comments = payload._embedded.comment;
        delete payload._embedded;

        payload = { comments: comments, post: payload };
        return this._super(store, type, payload, id, requestType);
      },

      normalizeHash: {
        // Next, normalize individual comments, which (after `extract`)
        // are now located under `comments`
        comments: function(hash) {
          hash.id = hash._id;
          hash.title = hash.comment_title;
          delete hash._id;
          delete hash.comment_title;
          return hash;
        }
      }
    })
    ```

    When you call super from your own implementation of `extractSingle`, the
    built-in implementation will find the primary record in your normalized
    payload and push the remaining records into the store.

    The primary record is the single hash found under `post` or the first
    element of the `posts` array.

    The primary record has special meaning when the record is being created
    for the first time or updated (`createRecord` or `updateRecord`). In
    particular, it will update the properties of the record that was saved.

    The primary record has special meaning when responding to `findQuery`

    If your primary array contains secondary (embedded) records of the same type,
    you cannot place these into the primary array `posts`. Instead, place the
    secondary items into an underscore prefixed property `_posts`, which will
    push these items into the store and will not affect the resulting query.

  // 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:

    ```js
    App.Comment = 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.

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      serialize: function(post, options) {
        var json = {
          POST_TTL: post.get('title'),
          POST_BDY: post.get('body'),
          POST_CMS: post.get('comments').mapProperty('id')
        }

        if (options.includeId) {
          json.POST_ID_ = post.get('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.

    ```js
    App.ApplicationSerializer = DS.RESTSerializer.extend({
      serialize: function(record, options) {
        var json = {};

        record.eachAttribute(function(name) {
          json[serverAttributeName(name)] = record.get(name);
        })

        record.eachRelationship(function(name, relationship) {
          if (relationship.kind === 'hasMany') {
            json[serverHasManyName(name)] = record.get(name).mapBy('id');
          }
        });

        if (options.includeId) {
          json.ID_ = record.get('id');
        }

        return json;
      }
    });

    function serverAttributeName(attribute) {
      return attribute.underscore().toUpperCase();
    }

    function serverHasManyName(name) {
      return serverAttributeName(name.singularize()) + "_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.

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      serialize: function(record, options) {
        var json = this._super(record, options);

        json.subject = json.title;
        delete json.title;

        return json;
      }
    });
    ```

    @method serialize
    @param record
    @param options
  */
  serialize: function(record, options) {
    return this._super.apply(this, arguments);
  },

  /**
    You can use this method to customize the root keys serialized into the JSON.
    By default the REST Serializer sends camelized root keys.
    For example, your server may expect underscored root objects.

    ```js
    App.ApplicationSerializer = DS.RESTSerializer.extend({
      serializeIntoHash: function(data, type, record, options) {
        var root = Ember.String.decamelize(type.typeKey);
        data[root] = this.serialize(record, options);
      }
    });
    ```

    @method serializeIntoHash
    @param {Object} hash
    @param {subclass of DS.Model} type
    @param {DS.Model} record
    @param {Object} options
  */
  serializeIntoHash: function(hash, type, record, options) {
    hash[type.typeKey] = this.serialize(record, options);
  },

  /**
    You can use this method to customize how polymorphic objects are serialized.
    By default the JSON Serializer creates the key by appending `Type` to
    the attribute and value from the model's camelcased model name.

    @method serializePolymorphicType
    @param {DS.Model} record
    @param {Object} json
    @param relationship
  */
  serializePolymorphicType: function(record, json, relationship) {
    var key = relationship.key,
        belongsTo = get(record, key);
    key = this.keyForAttribute ? this.keyForAttribute(key) : key;
    json[key + "Type"] = belongsTo.constructor.typeKey;
  }
});

})();

/**
  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.

  ## 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
  {
    "post": {
      title: "I'm Running to Reform the W3C's Tag",
      author: "Yehuda Katz"
    }
  }
  ```

  ### 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:

  ```js
  App.Person = DS.Model.extend({
    firstName: DS.attr('string'),
    lastName: DS.attr('string'),
    occupation: DS.attr('string')
  });
  ```

  The JSON returned should look like this:

  ```js
  {
    "person": {
      "firstName": "Barack",
      "lastName": "Obama",
      "occupation": "President"
    }
  }
  ```

  ## Customization

  ### Endpoint path customization

  Endpoint paths can be prefixed with a `namespace` by setting the namespace
  property on the adapter:

  ```js
  DS.RESTAdapter.reopen({
    namespace: 'api/1'
  });
  ```
  Requests for `App.Person` would now target `/api/1/people/1`.

  ### Host customization

  An adapter can target other hosts by setting the `host` property.

  ```js
  DS.RESTAdapter.reopen({
    host: 'https://api.example.com'
  });
  ```

  ### Headers customization

  Some APIs require HTTP headers, eg to provide an API key. An array of
  headers can be added to the adapter which are passed with every request:

  ```js
  DS.RESTAdapter.reopen({
    headers: {
      "API_KEY": "secret key",
      "ANOTHER_HEADER": "asdsada"
    }
  });
  ```

/**
  The ActiveModelAdapter is a subclass of the RESTAdapter designed to integrate
  with a JSON API that uses an underscored naming convention instead of camelcasing.
  It has been designed to work out of the box with the
  [active_model_serializers](http://github.com/rails-api/active_model_serializers)
  Ruby gem.

  ## JSON Structure

  The ActiveModelAdapter expects the JSON returned from your server to follow
  the REST adapter conventions substituting underscored keys for camelcased ones.

  ### Conventional Names

  Attribute names in your JSON payload should be the underscored versions of
  the attributes in your Ember.js models.

  For example, if you have a `Person` model:

  ```js
  App.FamousPerson = DS.Model.extend({
    firstName: DS.attr('string'),
    lastName: DS.attr('string'),
    occupation: DS.attr('string')
  });
  ```

  The JSON returned should look like this:

  ```js
  {
    "famous_person": {
      "first_name": "Barack",
      "last_name": "Obama",
      "occupation": "President"
    }
  }
  ```

  @class ActiveModelAdapter
  @constructor
  @namespace DS
  @extends DS.Adapter
**/

  defaultSerializer: '_ams',

    The ActiveModelAdapter overrides the `pathForType` method
    to build underscored URLs.

    ```js
      this.pathForType("famousPerson");
      //=> "famous_people"
    ```

    @method pathForType
    @param {String} type
