Why you use cls.create(username=username...) ? Why do not use simple cls(username=username...)?

1 Answer


I think this is because cls refers to the class where we define create_user (which is User). Thanks to the @classmethod, you don't need to create an instance (which is what you would be doing with cls(username=username) ).

Hope this helps (:
