InvalidBasesError: Cannot resolve bases for []

Question

When I run tests I get this error during database initialization:

django.db.migrations.state.InvalidBasesError: Cannot resolve bases for [

        

Answer 1

I've come across this issue, and as commenting out the model isn't really a solution, I've found that setting the undocumented auto_created = True to the Meta class will make Django ignore it.

class GroupProxy(Group):

    class Meta:
        proxy = True
        auto_created = True
