Я пытаюсь написать модульные тесты для приложения с несколькими базами данных django. Я использую настраиваемый маршрутизатор для всех этих баз данных, и я настроил его для маршрутизации auth и contenttypes в конкретную c БД (назовите ее DB_1), которая также содержит другие таблицы, одна из которых называется Account и имеет внешний ключ для модели User от auth.
В целом все работает нормально, и сейчас я пытаюсь написать модульные тесты, но когда тестовый прогон создает тест база данных, и все мои модели для app_1 созданы в DB_1, таблицы auth не созданы, что вызывает ошибку django.db.utils.OperationalError: no such table: auth_user.
вот точный результат:
$ python3 ./manage.py test -v 3 app_1
Skipping setup of unused database(s): DB_2, DB_3, DB_4, DB_5, default.
Creating test database for alias 'DB_1' ('file:memorydb_DB_1?mode=memory&cache=shared')...
Operations to perform:
Synchronize unmigrated apps: app_1, app_2, app_3, app_4, app_5
Apply all migrations: auth, contenttypes
Running pre-migrate handlers for application app_2
Running pre-migrate handlers for application app_1
Running pre-migrate handlers for application auth
Running pre-migrate handlers for application contenttypes
Synchronizing apps without migrations:
Creating tables...
Creating table ACCOUNT
Creating table another_one

Creating table etc
