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

Just incase anyone made the same mistake as me, I had the same issue because I hadn't made any migrations for the Proxy models. It didn't seem necessary to me as they don't have their own DB tables and I didn't see anything mentioning this in the docs. python manage.py makemigrations fixed it right up.
