auth.User.groups: (fields.E304) Reverse accessor for 'User.groups' clashes with reverse accessor for 'UserManage.groups'

Add the following to settings.py:

AUTH_USER_MODEL = "users_management.UserManage" 

More generally,

AUTH_USER_MODEL = 'YourAppName.YourClassName'

• YourAppName: This is the name of the app that will have the User Model
• YourClassName: This is the name of the class used inside the models.py file

Add this in the settings :

AUTH_USER_MODEL = 'APPNAME.User'

This way we are telling Django to use our custom model instead the default one. https://docs.djangoproject.com/en/2.2/topics/auth/customizing/#substituting-a-custom-user-model
