Как сделать вход в django через таблицу, отличную от auth_users?

Не уверен, что я делаю неправильно, я оставлю ниже свои файлы. Метод register работает отлично, но когда я делаю login, каждый раз вывод user is none.

Кто-нибудь знает, что я сделал не так?

Я прочитал документацию по аутентификации в django, но не могу обнаружить проблему. Я видел, что было несколько вопросов по этой проблеме, но я не смог решить свой. settings.py
