Python 域限制不起任何作用

你好，我有一个简单的表单，我想保存信息。我在表单中添加了域名限制，但它仍然可以保存其他电子邮件域名的电子邮件。我是django的新手，所以也许这是一项简单的任务，谢谢

models.py

        mail=models.EmailField(max_length=128,blank=False)

            return self.name

您应该使用

form\u class

attribute而不是

form

：

类WPGroupView（generic.CreateView）：
模板_name='wp.html'
form_class=WPGroupForm
模型=WPGroup
success\u url='success/'

---

此外，您的验证方法必须是name

clean\u**fieldname**

，因此它应该是

clean\u mail

，而不是

clean\u email

，

您的字段似乎被称为“mail”，因此该方法应该是

clean\u mail

，不

clean_email

。我更改了它，但它仍然是您所使用的，但表单类和字段不允许一起使用，我更改了它，也许您也可以在回答中删除它。
