Django error: relation "users_user" does not exist

Another issue can also be the fact that you were using the database for another application. So if this can be the case just drop the database before making migrations again

Inside your user app, you should have a folder migrations. It should only contain 0001_initial.py and __init__.py. Is that correct?

Try running ./manage.py sqlmigrate user 0001_initial and see what it does, because thats where the error comes from
