NOT NULL constraint failed: boards_topic.starter_id

Getting the following error:

Things that I've tried to resolve it:

1- Reset migrations
2- Grep around the different files to find the "boards_topic" pattern, only found it on the db.sqlite binary. Which is created from the models and in the models.py there is no "boards_topic" - So no sure whats going on here.. Please advise.

Same issue. All I had to do was create the user.
Now everything is ok.

    def setUp(self):
        Board.objects.create(name='Django', description='Django board')
        User.objects.create_user(username='marcix', email='[email protected]', password='123')

Implemented your solution and it worked! :) Thank you! @marcio-nunes ..
Can you please explain what is happening and how things are changing after I create the user?
