title: Django - Display "Model Object" in the admin page instead of Object title
body: <p>As displayed in the image it displays "Lecture Object" instead of the Lecture's title. As I've understood it, <strong>unicode</strong> should take care of this, but it doesn't seem to here.</p>
  
  <p>Here is my <strong>unicode</strong> method:</p>
  
  <pre><code>def __unicode__(self):
      return self.title
  </code></pre>
