   related_name="student_account") def str(self): return self.user.username

Answer 1

I've done something very similar before having students and teachers,but for me what I did was make the student and teacher model inherit from User class. With that in mind,my permission classes looked like this:

class IsStudent(permissions.BasePermission):
    def has_permission(self, request, view):
        return request.user.student and request.user.is_authenticated
