Надеюсь, у вас все хорошо.Так как несколько часов назад у меня возникла ошибка при расширении модели Django «Пользователь», с целью добавления некоторых полей для разных пользователей.
Для расширения модели я использовал два основных источника:
Репозиторий Django на Github - https://github.com/django/django/blob/master/django/contrib/auth/models.py
и из блога - simpleisbetterthancomplex - https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html#abstractbaseuser
Версия Django = 2.1
Во время выполнения команды - python manage.py makemigrations , я получил следующую ошибку:
"AUTH_USER_MODEL относится к модели«% s», который не был установлен »% settings.AUTH_USER_MODEL django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL относится к модели« core.User », которая не была установлена
При желанииопределить в settings.py - AUTH_USER_MODEL = 'core.User'
И да, у меня есть приложение под названием "core", которое уже находится в INSTALLED_APPS
settings.py
