title: Tying in to Django Admin's Model History
body: <p><strong>The Setup:</strong></p>
  
  <ul>
  <li>I'm working on a Django application which allows users to create an object in the database and then go back and edit it as much as they desire.</li>
  <li>Django's admin site keeps a history of the changes made to objects through the admin site.</li>
  </ul>
  
  <p><strong>The Question:</strong></p>
  
  <ul>
  <li>How do I hook my application in to the admin site's change history so that I can see the history of changes users make to their "content"?</li>
  </ul>
