在CBV的post方法中，我坚持使用userprofileform进行初始化，并且实例从对super（）的调用中收到None对象... 该模型非常标准：用户及其个人资料； uerprofile模型具有用户属性（ onetoone ）

当我影响UserProfileForm到profile_form时，视图的post方法中会发生错误。调试工具栏返回“ UserProfile没有用户” 。
UserProfileForm的 init 方法与视图的get方法一起使用（实例通过user.profile设置），但在发布时未给出实例（将user.profile作为数据丢弃是无意义的）包含在resquest.POST中）。
