Basic session handling

app_initializers_session-service.js

export function initialize(container, application) {
  application.inject('service:session', 'store', 'store:main');
  application.inject('route', 'session', 'service:session');
  application.inject('controller', 'session', 'service:session');
  application.inject('model', 'session', 'service:session');
  application.inject('component', 'session', 'service:session');
  application.deferReadiness();
  // load the current session
  container.lookup('service:session').load().then(function () {
    application.advanceReadiness();
  });
}

/**
 * @class SessionServiceInitializer
 */
export default {
  name:       'session-service',
  after:      'store',
  initialize: initialize
};

app_models_session.js

import DS from 'ember-data';

/**
 * @class Session
 * @extends DS.Model
 */
export default DS.Model.extend({
  /**
   * The user owning the session
   * @property user
   * @type {User}
   */
  user: DS.belongsTo('user')
});

app_routes_any.js

// that can be any controller, route, model or component since we injected in all of them
import Ember from 'ember';

export default Ember.Route.extend({
   // any method where you need to access the session service:
   someMethod: function () {
      // this.session is the service object, and since we extended it from ObjectController, it acts as a proxy for the session record:
      this.session.get('user.name');//...
   }
});

app_services_session.js

import Ember from 'ember';

export default Ember.ObjectController.extend({
   isAuthenticated: Ember.computed.bool('model.user.isClaimed'),
   
   load: function () {
      var _this = this;
      return this.store.find('session', yourSessionCookieOrWhatever).then(function (session) {
         _this.set('model', session);
         return _this;
      }).catch(function () {
         // create a session or handle the way you handle no session with your app
         return _this;
      });
   }
});

app_templates_any.hbs

{{! since we injected our service on the controllers, we have direct access to it with `session`}}
{{#if session.isAuthenticated}}
  Logged in as {{session.user.name}}
{{/if}}

@huafu, thanks for writing this, spent many hours trying to get a solution working and finally got one working... https://github.com/erichonkanen/cl-frontend/blob/master/app/initializers/session.coffee

However the magic was that I discovered you can use "selectionBinding" instead of "value=" in the select view.. that fixed it and made it work for me... I have no idea why that's not in the ember docs!!! Not even sure whats different

Thanks for the help!
