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

Simply creating a migrations directory at the root of your app (so users/migrations/ in your case) and adding an empty __init__.py file might resolve your issue. At least it did for me when I was getting the same error.

But you're better off running makemigrations for your app, as suggested by @zenofewords above. That will create the directory for you AND generate migrations for your proxy models.

Why does Django create migration files for proxy models?

Your tests are looking for those migrations and aren't finding them.
