title: Ember-Data Fixture Adapter
body: <p>Is there a commit method for the fixture adapter? What does it do?
  As my understanding goes <code>store.commit()</code> puts an API call when used with REST adapter.</p>
  
  <p>Can I use <code>isLoaded</code> property with fixture adapter?</p>
  
  <p>Basically I have 2 records in my controller called <code>x</code> and <code>y</code> and a property content that has many records of <code>y</code> type.
  Coffee code below:</p>
  
  <pre class="lang-coffeescript prettyprint-override"><code>someMethod: (-&gt;
    content.removeObject(y)
  ).('x.isLoaded')
  
  anotherMethod: -&gt;
    //modify x
    Application.store.commit()
  </code></pre>
  
  <p>When I call <code>anotherMethod</code> it updates <code>x</code> and runs a commit on store, hence <code>someMethod</code> gets called.
  My actual application runs fine but in case of tests <code>someMethod</code> removes the record <code>y</code> from content as well as store.
  Is it that <code>isLoaded</code> and <code>commit</code> are not for fixture data store?</p>
