I am running Django 1.10.4 with Python 3.4.3, learning about Django. I created a custom user model 'MyUser' copied from the Django docs at https://docs.djangoproject.com/en/1.10/topics/auth/customizing/#substituting-a-custom-user-model; this works fine.
Then I renamed the model from 'MyUser' to 'TheUser', updating models.py,
admin.py and settings.py and succesfully ran 'makemigrations'. Then, when
I run 'migrate', I get the traceback below.
If I temporarily comment the AUTH_USER_MODEL setting, makemigrations works
fine, but as soon as I uncomment the AUTH_USER_MODEL setting again, both
'makemigrations' and 'migrate' fail with the same error and a similar
traceback.
I did not do any additional changes to the model, so makemigrations and
migrate should actually not do anything at this point.
Is this a bug?
I have attached a complete project that can be used to reproduce the
problem.
$ python manage.py makemigrations
