Django Reverse Accessor Clashes

related_name‘s must be unique. You’re giving the same name to all the related_name‘s.

Try to rename them like this:

user = models.OneToOneField(User, related_name="custom_user_profile", primary_key=True)
#..
provider = models.OneToOneField(Provider, related_name="user_ind_provider_profile")
#..
provider = models.OneToOneField(Provider, related_name="user_org_provider_profile")
