[Django] makemigration시 발생하는 (fields.E304) 오류

user 하위의 models.py에서 AbstractUser를 import해서 UserModel에 상속 받아온 뒤 python manage.py runsever를 실행 해줬는데, 오류가 떴다.

SystemCheckError: System check identified some issues:

ERRORS:
auth.User.groups: (fields.E304) Reverse accessor 'Group.user_set' for 'auth.User.groups' clashes with reverse accessor for 'user.UserModel.groups'.
        HINT: Add or change a related_name argument to the definition for 'auth.User.groups' or 'user.UserModel.groups'.

django 문서를 찾아보니 settings.py에 AUTH_USER_MODEL를 추가해주지 않아서 그렇다고 한다.

추가해주자 !

# settings.py
AUTH_USER_MODEL = 'user.UserModel'

이렇게 추가시켜주면 잘 돌아간다!
