Cannot understand django user group change signal behavior
I have a function to receive a signal when users change their group. @receiver(signal=m2m_changed, sender=User.groups.through) def save_profile(instance, action, reverse, model, pk_set, using, *args, **kwargs): print(model, instance) When I change the group of the user with username "test" using the superadmin interface it outputs <class 'django.contrib.auth.models.Group'> test. But when I do it using following code, group = Group.objects.get(name='Customer') group.user_set.add(user) user.save() it outputs <class 'django.contrib.auth.models.User'> Customer. Because of the above issue I cant use if instance.groups.filter(name='Customer').exists(): #Do something inside the save_profile funtion. When I change groups using second method it gives AttributeError at /register/ 'Group' object has no attribute 'groups' error. How can I avoid getting this error? -
