У меня свежая установка приложения django, которое использует background_tasks. Если я удалю модели, использующие background_task, то смогу сделать
python manage.py makemigrations
Однако, если я сохраню их, я получу исключение из таблицы:
"mydb.background_task doesn't exist"
Я видел другиелюди с этой проблемой, но я попробовал каждое предложение: - удалить все файлы миграции - удалить файл дампа sqlite3 - удалить django и django-background-tasks - убедиться, что на моей машине не установлены эти два пакета даже вне virtualenv - япопытался удалить мой virtualenv и переустановить все.
Я пробовал все это, и pym manage.py makemigrations все еще дает мне это исключение. Но больше ничего этого не делает.
Django==2.1.5
django-background-tasks==1.2.0
django-compat==1.0.15
django-mysql==3.2.0
ps: я использую Cloud SQL, я не знаю, влияет ли это на что-то, я так не думаю. та же проблема с mysql
РЕДАКТИРОВАТЬ: добавление трассировки

Также я уже пробовал:
find . -path "*/migrations/*.pyc" -delete
find . -path "*/migrations/*.py" -not -name "__init__.py" -delete
Я попытался переустановить и удалить.
Кроме того, такая же ошибка возникает, если я выполняю pym manage.py showmigrations.
Вот часть модели, где, если я закомментирую @background, она работает, но с @background она не работает.
