在 django 中的 EmailField 验证中例外

发布于 2024-10-17 02:29:32 字数 595 浏览 1 评论 0原文

我有一个名为 EmailHistory 的模型，其中一个字段如下所示：

from_email = models.EmailField(verbose_name="From:")

我创建了一个 ModelForm 并希望验证电子邮件地址，除非将其设置为“匿名”。我尝试了以下方法，但没有成功。

class EmailForm(ModelForm):
    class Meta:
        model = EmailHistory
        exclude = ('to_email')

    to_emails = forms.CharField()

    def clean_from_email(self):

        from_email = self.cleaned_data['from_email']
        if from_email == "Anonymous":
            return from_email
        else:
            return super(EmailForm, self).clean_from_email();

I have model called EmailHistory with one of the fields that look like this:

from_email = models.EmailField(verbose_name="From:")

I created a ModelForm and want to validate for email addresses unless it's set to "Anonymous". I tried the following, to no avail.

class EmailForm(ModelForm):
    class Meta:
        model = EmailHistory
        exclude = ('to_email')

    to_emails = forms.CharField()

    def clean_from_email(self):

        from_email = self.cleaned_data['from_email']
        if from_email == "Anonymous":
            return from_email
        else:
            return super(EmailForm, self).clean_from_email();

我怀疑问题在于，正如文档所解释的那样， <底层表单字段的 code>clean 方法（依次运行验证器）在表单本身的特定 clean_form_field 方法之前运行。您可能希望在表单中使用普通的 CharField，并自行将电子邮件验证添加到 clean 方法中。

如果不重新定义 from_email，我就无法让它工作。因此，我重新定义了它，然后使用 django.core.validators.validate_email 进行了电子邮件验证：

class EmailForm(ModelForm):
    class Meta:
        model = EmailHistory
        exclude = ('to_email')

    to_emails = forms.CharField()
    from_email = forms.CharField(required=True)

    def clean_from_email(self):
        from_email = self.cleaned_data['from_email']
        if from_email == "Anonymous":
            from_email = "[email protected]"

        validate_email(from_email)

        return from_email

I couldn't get it to work without redefining from_email. So, I redefined it and then did an email validation using django.core.validators.validate_email:

class EmailForm(ModelForm):
    class Meta:
        model = EmailHistory
        exclude = ('to_email')

    to_emails = forms.CharField()
    from_email = forms.CharField(required=True)

    def clean_from_email(self):
        from_email = self.cleaned_data['from_email']
        if from_email == "Anonymous":
            from_email = "[email protected]"

        validate_email(from_email)

        return from_email
