How to call a newly added field in a class in Django?

Question

Django

models.py
role_type = models.CharField(max_length=40, verbose_name="User Role")
group = models.ForeignKey(Group, on_delete=models.PROTECT, default=1, verbose_name='Group')
views.py
user = User .objects.get(username='my_user')
profile = Profile.objects.get(user=user)
user_role_group = profile.role.group
Throws
Traceback error (most recent call last):
File "", line 1, in
AttributeError: 'Role' object has no attribute 'group'
The group field was added later.
