python - How can I create CustomUser (which inherits django's User) if I have instance of User?

Question

I have CustomUser class

class CustomUser(User):
    some_extra_field = models.CharField(max_length=30, blank=True)

Now in some view I get User instance as argument and inside this view I want to create CustomUser instance based on that argument.

Should I do this like this?

def view(user):
    custom_user = user
    custom_user.__class__ = CustomUser

这个关于扩展用户模型的问题有帮助吗？
