如何链接这两个模型，以便更新同一个实例？

I really want to build this app with Django that lets people register and create User instances that can be edited. Each User instance is already linked to a UserProfile with OneToOne because I didn't want to mess with the original User model. The UserProfile will have a field where he/she can register a game if that person is logged in.I really want to build this app with Django tha
