title: How do you specify a default for a Django ForeignKey Model or AdminModel field?
body: <p>How can I set a default value on a ForeignKey field in a django Model or AdminModel?</p>
  
  <p>Something like this (but of course this doesn't work)...</p>
  
  <pre><code>created_by = models.ForeignKey(User, default=request.user)
  </code></pre>
  
  <p>I know I can 'trick' it in the view, but in terms of the AdminModel it doesn't seem possible.</p>
