Django 表单在基于 class 的视图中无效
Django form is not valid in class based view
我目前正在开发一个博客项目，我在其中创建了一个自定义用户模型，我打算在其中根据该自定义用户模型创建注册表单。我的注册表单继承自 Django 中的 UserCreationForm。表单在我的模板中正确呈现，但每当我尝试注册用户时，表单都无效。我不确定我做错了什么。我期待着从你们这些聪明的人那里得到一些帮助！ :-)

请注意，每当我尝试提交表单时，它实际上会打印 request.POST.get('first_name') 和其他字段，并且我在控制台中看到提交的值，但表单本身仍然无效，所以我不明白。请帮忙...
所以我做错的是，我使用了 password 而不是 password1 和 password2 因为根据从 [=15= 收到的消息，这两个是必需的].在 forms.py 文件中更新我的表单后，该表单现在声明它是有效的。
更新：
