RegistryProxyMixin (private)

Module: ember

hasRegistration (fullName) Boolean public

Boolean

Check if a factory is registered.

Define a dependency injection onto a specific factory or all factories of a type.

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:

let App = Ember.Application.create();
let Session = Ember.Object.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 = Ember.Controller.extend({
  isLoggedIn: Ember.computed.alias('session.isAuthenticated')
});

Injections can also be performed on specific factories.

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 classes that are instantiated by Ember itself. Instantiating a class directly (via create or new) bypasses the dependency injection system.

register (fullName, factory, options) public

fullName
String
type:name (e.g., 'model:user')
factory
Function
(e.g., App.Person)
options
Object
(optional) disable instantiation or singleton usage

Registers a factory that can be used for dependency injection (with inject) or for service lookup. Each factory is registered with a full name including two parts: type:name.

A simple example:

let App = Ember.Application.create();

App.Orange = Ember.Object.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:

let App = Ember.Application.create();
let Session = Ember.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 = Ember.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:

let App = Ember.Application.create();

App.Person = Ember.Object.extend();
App.Orange = Ember.Object.extend();
App.Email = Ember.Object.extend();
App.session = Ember.Object.create();

App.register('model:user', App.Person, { singleton: false });
App.register('fruit:favorite', App.Orange);
App.register('communication:main', App.Email, { singleton: false });
App.register('session', App.session, { instantiate: false });

registerOption (fullName, optionName, options) public

fullName
String
optionName
String
options
Object

Register an option for a particular factory.

registerOptions (fullName, options) public

fullName
String
options
Object

Register options for a particular factory.

registerOptionsForType (type, options) public

type
String
options
Object

Allow registering options for all factories of a type.

let App = Ember.Application.create();
let appInstance = App.buildInstance();

// if all of type `connection` must not be singletons
appInstance.registerOptionsForType('connection', { singleton: false });

appInstance.register('connection:twitter', TwitterConnection);
appInstance.register('connection:facebook', FacebookConnection);

let twitter = appInstance.lookup('connection:twitter');
let twitter2 = appInstance.lookup('connection:twitter');

twitter === twitter2; // => false

let facebook = appInstance.lookup('connection:facebook');
let facebook2 = appInstance.lookup('connection:facebook');

facebook === facebook2; // => false

registeredOption (fullName, optionName) Object public

fullName
String
optionName
String
returns
Object
options

Return a specific registered option for a particular factory.

registeredOptions (fullName) Object public

fullName
String
returns
Object
options

Return registered options for a particular factory.

registeredOptionsForType (type) Object public

type
String
returns
Object
options

Return the registered options for all factories of a type.

resolveRegistration (fullName) Function public

fullName
String
returns
Function
fullName's factory

Given a fullName return the corresponding factory.

unregister (fullName) public

fullName
String

Unregister a factory.

let App = Ember.Application.create();
let User = Ember.Object.extend();
App.register('model:user', User);

App.resolveRegistration('model:user').create() instanceof User //=> true

App.unregister('model:user')
App.resolveRegistration('model:user') === undefined //=> true
