Если в моем коде есть какая-либо ошибка (код в модели, которая используется в представлении, которое использует LoginRequiredMixin), например Ошибка как:
if (True: # <-- example bug to show how bugs like this are hidden
Тогда я получаю следующую ошибку:
"AUTH_USER_MODEL refers to model '%s' that has not been installed" % settings.AUTH_USER_MODEL
django.core.exceptions.ImproperlyConfigured:
AUTH_USER_MODEL refers to model 'auth.User' that has not been installed
Это очень затрудняет отладку кода. Я понял, удаляю ли я эту строку из моего views.py:
from django.contrib.auth.mixins import LoginRequiredMixin
Даже если я удаляю все экземпляры, где используется LoginRequiredMixin, просто импортируя его, он скрывает истинную ошибку и генерирует вышеуказанную ошибку аутентификации.
Я прочитал: AUTH_USER_MODEL относится к модели "% s", которая не была установлена "% settings.AUTH_USER_MODEL
Мое исследование показывает, что большую часть времени это происходит из-за отсутствия django.contrib.auth в INSTALLED_APPS, который вы видите у меня (фрагмент settings.py, Django 2.2):
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth', # <-- Important for this topic!
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'myapp.apps.CommonConfig',
]
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
Я попытался добавить это к импорту mixim выше, но ничего не помогло:
from django.contrib import auth
from django.contrib.auth.models import User
Эта часть полной трассировки соответствует приведенному выше:

Как мне сделать так, чтобы ошибка аутентификации не выдавалась ложно?
