title: Ember - Record ID not returned (null) after successful insertion to the backend
body: <p>Hi and thanks for taking the time to answer my question.</p>
  
  <p>I have the following code in my controller:</p>
  
  <pre><code>.
  .
  .
  
  var project = this.store.createRecord('project', {
                  name: projectName,
              });
  
              project.save();
              alert(project.get('id') + project.get('name'));
  .
  .
  .
  </code></pre>
  
  <p>This adds the record successfully to the db and the front end is automatically refreshed to reflect these changes. When the alert is executed however, only the name is printed.</p>
  
  <p>For the ID i get null. </p>
  
  <p>Basically I need to get the id value returned from the server after the record has been successfully isnerted. I checked the returned JSON:</p>
  
  <pre><code>{"project":{"id":6,"name":"dfgdgf", "created_at":"2014-01-02T08:37:57.491Z","updated_at":"2014-01-02T08:37:57.491Z"}}
  </code></pre>
  
  <p>so the id field is contained in the json response. Could the problem occur because the server also returns two fields (created_at and updated_at) which are not found in the ember model??</p>
  
  <p>Thank you so much!</p>
  
  <p>EDIT:</p>
  
  <p>I included <code>created_at</code> and <code>updated_at</code> in my model in ember and am still getting null when I try to call <code>project.get('id');</code></p>
  
  <p>Any suggestions?</p>
  
  <p>Thanks</p>
