title: Ember.js Model with embedded object
body: <p>I'm going to query an API that return embedded objects in the response, so I'm simulating this with the fixture adapter. My data looks like this:</p>
  
  <pre><code>App.Deal.FIXTURES = [
        {id: 1, name: 'Deal 1', closed_time: '2012-04-01', value_in_cents: 342345, company: { id: 1, name: 'Google' }, user: { id: 2, full_name: 'Bob Smith' } },
        {id: 2, name: 'Deal 2', closed_time: '2012-04-01', value_in_cents: 342345, company: { id: 1, name: 'Google' }, user: { id: 2, full_name: 'Bob Smith' } }
  ]
  </code></pre>
  
  <p>Here's my models:</p>
  
  <pre><code>App.Deal = DS.Model.extend({
    name: DS.attr('string'),
    value_in_cents: DS.attr('number'),
    closed_time: DS.attr('date'),
    user: DS.belongsTo('App.User'),
    company: DS.belongsTo('App.Company')
  });
  
  App.User = DS.Model.extend({
    full_name: DS.attr('string')
  });
  
  App.Company = DS.Model.extend({
    name: DS.attr('string')
  });
  </code></pre>
  
  <p>I'm unsure of how to get at the <code>user</code> and <code>company</code> objects. I see the data via console:</p>
  
  <pre><code>App.Deal.find(1)
  Class {store: Class, clientId: 2, _relationshipChanges: Object, _changesToSync: Object, id: "1"…}
  __ember1365792240874: "ember329"
  __ember1365792240874_meta: Meta
  _changesToSync: Object
  _data: Object
  attributes: Object
  belongsTo: Object
  company: Object
  id: 1
  name: "Google"
  __proto__: Object
  </code></pre>
  
  <p>But I can't do <code>App.Deal.find(1).get('user')</code>. Am I missing something?</p>
