Question

给定一个电子邮件地址（例如：goelv@example.com），如何验证域（“example.com”）是否包含在给定的域列表中。如果域（“example.com”）不在指定的列表中，表单应该引发某种错误。

这是我目前在forms.py

中所拥有的

class UserCreationFormExtended(UserCreationForm):
    email = forms.EmailField(required=True)

    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2",)

    def clean_email(self):
        data = self.cleaned_data['email']
        domain = data.split('@')[1]
        domain_list = ["gmail.com", "yahoo.com", "hotmail.com",]
        if domain not in domain_list:
            raise forms.ValidationError["Please enter an Email Address with a valid domain"]
        return data

    def save(self, commit=True):
        user = super(UserCreationFormExtended, self).save(commit=False)
        user.email = self.cleaned_data["email"]
        if commit:
            user.save()
        return user

使用此代码，我收到错误“'type'对象没有属性' getitem '”，它跟踪到我的“raise forms.ValidationError [...]”行代码。

谁能看到我做错了什么？谢谢你的帮助！

Answer 1

您需要在()行中使用[]代替raise，如下所示：

raise forms.ValidationError("Please enter a valid Penn Email Address")

Answer 2

我认为这句话......

raise forms.ValidationError["Please enter an Email Address with a valid domain"]

应该是

raise forms.ValidationError("Please enter an Email Address with a valid domain")

如何验证表单中的电子邮件地址域？
