Angular

angular raffler railscasts rails app

• only sending certain Entry attributes back, for example, skipping created_at and updated_at. This way they are not part of the posted attributes either.
• Added strong parameters into the mix
• Added a solution from stack overflow to address CSRF security

Notes

• angular has a subset of jquery called jqlite. If jQuery is available, angular.element is an alias for the jQuery function.
• $watch and $apply are used for the two-way data binding
• ng-show attribute can be used when an attribute should be shown/hidden by the controller
• function defined on ng-submit on form, there should be a controller function that matches that name
• scope object lets us interact with a view
• add ng-app attribute to html tag
• ng-model: bind a model to the form element, e.g. newEntry.name
• ng-repeat attribute on a list item
• for a controller, use @ symbol to expose the object to the window
• two-way data binding
• with asset minification, for rails asset pipeline, can set mangle: false for the uglifier
• a promise is a technique for performing asynchronous tasks. then() takes an argument that is a function to run when the promise is fulfilled.
• module can have a config function, that can have different routes, routes can define view and controller, controllers call out to a factory/service/providers/value/resources
• $routeProvider, when, when, otherwise, see ngRoute
• can chain factory and controller functions on the module
• factory and service are different in that factory author creates a JS object and returns it. Service uses this keyword. This might be awkward with coffeescript.
• can animate views

directives

• add new things to HTML, can create templates, add attributes, elements
• ng-init, ng-app, ng-repeat
• ng-click, argument is function like "addCustomer()"
• ng-view, routes can be used to define routes with multiple views, and click between them

filters

• {{ customer.name | uppercase }}
• filter:name
• `orderBy:'name'

Views, controllers, scope (view model)

• controller drives what gets updated into the view, $scope between view and controller
