疑问

我无法理解当我渲染配置文件表单进行编辑时，只有第一个名称和姓氏在那里但是当我填写详细信息并提交表单时，它会对用户配置文件进行更改，但是在重新加载时配置文件表单不是使用userprofile的值启动的，只设置了first_name和last_name值，我知道表单是用户模型表单，但是当我使用用户配置文件值启动它时，我不知道预期结果，请提前帮助，谢谢。

Answer 1

在UserProfileForm，

class Meta:
   model = User

需要改为

class Meta:
   model = UserProfile

Answer 2

正如Karthikr所说，您的表单正在加载用户模型（名/姓）中的值，而不是用户配置文件中的值。如果要显示正确的值，则需要根据正确的模型启动表单（在本例中为UserProfile）。
