How do I make an Ember initializer for current user? My backend has a /users/current route that simply spits out a serialized current_user. This works, but it fails when there's no current user because Ember tries to build a user model using the nil current_user. Seems kinda messy

initializer.coffee

Gameway.initializer
  name: 'currentUser'

  initialize: (container, application) ->
    store = container.lookup('store:main')
    user = store.find('user', 'current')
    # user = Gameway.User.find('current')

    container.lookup('controller:currentUser').set('content', user)
    container.typeInjection('controller', 'currentUser', 'controller:currentUser')

other_parts.coffee

Gameway.Router.map ()->
  @resource 'tournament_membership', { path: "/tournament_memberships/:tournament_membership_id"}

  @resource 'user', { path: '/users/:user_id'}


Gameway.User = DS.Model.extend(
  username: DS.attr()
  first_name: DS.attr()
  last_name: DS.attr()
  full_name: DS.attr()
  avatar_url: DS.attr()
  user_url: DS.attr()
  lol_account: DS.attr()
  starcraft2_account: DS.attr()
)

Gameway.CurrentUserController = Ember.ObjectController.extend
  isSignedIn: (->
    return this.get('content') && this.get('content').get('isLoaded')
  ).property('content.isLoaded')
