"Dependency on app with no migrations: %s" % key[0]

Problem Description: I built a model class in the model, run the console, it reported errors:

 

 

Solution: 1, first of all need to override the setting in AUTH_USER_MODEL

AUTH_USER_MODEL = 'users.UserProfile'

　　　　2, and then generate the migration file, specify the name of the app:

python manager.py makemigrations  users

　　　　3, finally will be able to migrate data

python manager.py migrate

　　　　4. If the migration is a problem, you might be generated by the migration file error, you can migrate files to delete and then repeat steps 2 and 3, do not specify the name of the app when repeat step 2.
