Hi All,
I am having hard time to get multiple roles for users in a project and
I am having errors.
I've added related_name but still getting error. Can please tell me
how to fix this?
The error provides a hint. You need an extra argument ...
related_name='user_role'
... or something else which makes sense for you in the context of your
app. See ...
