title: Update the relation to point at settings.AUTH_USER_MODEL
body: <p>I'm getting this error. I'm trying to configure tschellenbach/Django-facebook package. I was getting "user or profile didnt have attribute facebook_id" error. So I tried to configure it using the code from <a href="https://github.com/tschellenbach/Django-facebook/tree/master/facebook_example" rel="nofollow">facebook_example</a> which is a working example provided with the package. What should I do to sort it ? Please help</p>
  
  <pre><code>course.course: 'author' defines a relation with the model 'auth.User',
  which has been swapped out. Update the relation to point at 
  settings.AUTH_USER_MODEL.
