title: Django - Foreign Keys in Fixtures
body: <p>I have a fixture of "User" objects (just the default Django auth ones), and am trying to create a fixture of "Profile" objects.  Each profile has a one-to-one relation to a user object, and defines some more custom stuff for that user.</p>
  
  <p>As far as I can tell, the normal way of dealing with foreign keys in a fixture is to just hardcode the primary key of the foreign object into the fixture.  Is there a way to avoid doing that?</p>
  
  <p>Basically, I'm trying to have something like '"user":username' in the fixture rather than '"user":pk'.</p>
  
  <p>Is there any way to do this?</p>
