Question

用户只需填写两个字段中的一个我怎么会要这个？它会在哪里？

我正在尝试将其保存在保存中，但我相信它属于其他地方，因为验证错误弹出为Django错误屏幕，而不是字段验证错误。这是我尝试过的：

class SignupForm(forms.Form):
    learn1 = forms.CharField(max_length=50, label='Learn', required=False)
    teach1 = forms.CharField(max_length=50, label='Teach', required=False)

    class Meta:
        model = Profile

    def save(self, user):
        if not self.cleaned_data['learn1'] or self.cleaned_data['teach1']:
            raise forms.ValidationError("Specify at least one")
        user.is_profile_to.learn1 = self.cleaned_data['learn1']
        user.is_profile_to.teach1 = self.cleaned_data['teach1']
        user.save()
        user.is_profile_to.save()

Answer 1

def clean(self):
        cleaned_data = super().clean()
        if not self.cleaned_data['learn1'] or self.cleaned_data['teach1']:
            raise forms.ValidationError("Specify at least one")
        else:
            return cleaned_data


def save(self, user):
        user.is_profile_to.learn1 = self.cleaned_data['learn1']
        user.is_profile_to.teach1 = self.cleaned_data['teach1']
        user.save()
        user.is_profile_to.save()
