As you are looking up on pk against User id which is not right as you don't have made the name field as primary_key=True or inherited from User model itself. You have to look up on name field of profile
profile = Profile.objects.get(name_id=user_id)
You can set name as primary key like this:
name = models.ForeignKey(User, on_delete=models.CASCADE, primary_key=True)
and then you can look up on pk:
profile = Profile.objects.get(pk=user_id)
