Proper way to extend the User table and recovery from FK nightmare

Using Django Using the ORM
1

In my data model I created a UserProfile model that has a OneToOneField with User so that I could add some app specific fields for my users. Was working well enough. Then I wanted to make the email field unique…

So I created:
class CustomUser(AbstractUser):
email = models.EmailField(unique=True) # Ensure unique email addresses

and changed my OneToOneField to map to CustomUser rather than User.

(a) Is this a good way to add a few fields for my user records?
(b) When I tried the above I got stuck in ForeignKey exception hell… I cannot delete existing User or UserProfile records without throwing exceptions. I’m at an early stage here and am happy to just nix any User and UserProfile records to straighten this out. But I don’t know how to do that. :frowning:

Advice and suggestions welcome. Thanks!

Actually, this is less an issue of having an FK than the bigger issue of changing the User model after your first migration.

See all the docs in the section for Substituting a custom user model, specifically the section for Changing to a custom user model mid-project.
