내가 another StackOverflow question about this error을 확인

사용자,하지만 난하지 않습니다 여기 모델은 마이그레이션 할 준비가 의존성이 어디에 있을지에 대한 내 오류의 모든 정보. this advice을 따르려고했으나 swappable_dependency을 (를) 수정하는 방법을 모르 셨습니다. 어떤 아이디어? 감사!

Answer 1

1. In tweets/models.py comment #user = models.ManyToManyField('users.User', through = "users.UsersTweets") 
2. makemigrations tweets 
3. makemigrations users 
4. UNcomment in tweets/models.py user = models.ManyToManyField('users.User', through = "users.UsersTweets") 
5. makemigrations tweets 
6. migrate
