Charfield 必须与另一个 Charfield Django 表单验证匹配

Question

您好，我无法找到有关 charfield 必须与另一个 charfield 匹配的验证的文档

例如，我想要验证 new_password 必须与 confirm_new_password 匹配：

class ChangePassword(forms.Form):
    new_password = forms.CharField(label='New Password', max_length=100, error_messages={'required': 'New password is required'}, widget=forms.PasswordInput())
    confirm_new_password = forms.CharField(label='Confirm New Password', max_length=100, error_messages={'required': 'Confirm New password is required'}, widget=forms.PasswordInput())

https://docs.djangoproject.com/en/1.9/ref/forms/fields/#charfield

好像主要是required, max_length, min_length？

要执行自定义表单验证，您需要像这样覆盖 clean() 函数：

class ChangePassword(forms.Form):
    new_password = forms.CharField(label='New Password', max_length=100, error_messages={'required': 'New password is required'}, widget=forms.PasswordInput())
    confirm_new_password = forms.CharField(label='Confirm New Password', max_length=100, error_messages={'required': 'Confirm New password is required'}, widget=forms.PasswordInput())

    def clean(self):
        password = self.cleaned_data['new_password']
        confirm_password = self.cleaned_data['confirm_new_password']
        if password != confirm_password:
            raise forms.ValidationError('Your passwords do not match!')
