There are a few things being overlooked here: 1. This cookie has been baked before. Instead of talking about it in the abstract, check out django-profiles or django-basic-apps (and there are more I'm sure). That app will give you much better control over contact details for a user in a robust way. Just use that app and you can focus on import things like what your project does: http://bitbucket.org/ubernostrum/django-profiles/wiki/Home http://code.google.com/p/django-basic-apps/source/browse/#svn/trunk/profiles 2. There are two ways to handle the issue generally - A symmetrical one-to-one key allowing any profile to get its user or vice versa, and extending the User class with something like: class Profile(User): email = models.... phone = models.... @PlanetUnkown - you haven't really stated what's wrong with extending the user like that, nor what is wrong with the one-to-one, so nobody can help you any more than to tell you either one of those will do what you want it to do. I personally would extend the User model for your limited need but most profile apps use a ForeignKey field (OneToMany) so as to support multiple profiles per user.
