The issue seems to come from the fact that the order of operations
when you create the user looks like this:

1) Django admin saves the new User
2) post_save on User is triggered, and User's profile is created
3) Django admin saves the UserProfile... but it already exists, and an
integrity error is raised


I'm currently looking into a solution to this as well, and will let
you know what I find.

Have your signal handler check whether this is a creation of a user or an
edit. Only create the profile in the first case.

You may also need to check whether the profile already exists before trying
to create - get_or_create() is your friend here.

Userprofile, signal and admin inline edit.

[Jani Tiainen]

If I extend auth.User with custom profile and add automatic profile
creation signal it works as expected.

But if I try to add admin inline editor for profile when saving I get
exception about integration violation. 

It happens because admin tries to create second profile for user when
saving.

I can of course remove signal but that wouldn't create profile if I
insert user manually.

So how to make things work with both, admin inline profile editing and a
signal?
