Question

class RequestForm(forms.ModelForm):
    """ Online request.
    """
    class Meta:
        model = Request
        fields = ["language", "daytime", "daysofweek", "phone", "email", "name"]
        widgets = {
                'language': forms.Select(),
                'daytime': RadioSelectNotNull(),
                'daysofweek': forms.CheckboxSelectMultiple()
       }

如何安装强制性填写两个字段中的一个，＆＃39;电话＆＃39;或者＆＃39;电子邮件＆＃39;？

Answer 1

您并不完全清楚自己要问的内容，但如果目的是要求phone或email中至少有一个非空白，请使用自定义clean方法：

def clean(self):
    cleaned_data = super(ContactForm, self).clean()
    if not (cleaned_data.get('phone') or cleaned_data.get('email')):
        raise ValidationError('At least one of phone or email is required.')
    return cleaned_data

Answer 2

如果您设置模型字段blank=false，null=false，ModelForm会根据需要对其进行处理。默认设置为False。
