title: django admin registering dynamic model from action
body: <p>I have strange problem. In admin.py I can say:</p>
  
  <pre><code>admin.site.register(MyModel)
  </code></pre>
  
  <p>and this is obviously fine. Now I want this model to be loaded automatically as an result of user action:</p>
  
  <pre><code>def user_action_from_admin_panel(......):
      .....
      admin.site.register(MyModel)
  </code></pre>
  
  <p>MyModel class gets shows up in the admin as plain text without links.
  Any ideas to solve this?</p>
