Я пытаюсь подключить свое приложение django к mongoDB, для этого я использовал djon go. Когда я создаю простую модель без встроенных документов, миграции проходят идеально, но когда я пытаюсь создать документ встроенной модели в своей модели, при запуске python manage.py makemigrations.
появляется сообщение об ошибке «модели еще не загружены» Сначала я хотел бы знать, почему возникает эта ошибка и почему она возникает, когда я использую встроенные модели.

Я использую:
son==0.5.8
dataclasses==0.7
Django==2.2.12
djongo==1.3.2
pymongo==3.10.1
python-dateutil==2.8.1
pytz==2020.1
six==1.15.0
sqlparse==0.2.4
Единственные ответы, которые я нашел, - это те, которые объясняют, как использовать модели при использовании сценарий, но это не мой случай. Спасибо за помощь
