django覆盖表单清理方法

当覆盖表单清理方法时，您如何知道其对任何字段的验证是否失败？例如在下面的表单中，如果我覆盖 clean 方法，我如何知道表单是否在任何字段上验证失败？

class PersonForm(forms.Form):
    title = Forms.CharField(max_length=100)
    first_name = Forms.CharField(max_length=100)
    surname = Forms.CharField(max_length=100)
    password = Forms.CharField(max_length=100)

def clean(self, value):
    cleaned_data = self.cleaned_data

    IF THE FORM HAS FAILED VALIDATION:
        self.data['password'] = 'abc'
        raise forms.ValidationError("You have failed validation!")
    ELSE:
        return cleaned_data 

Thanks

您可以检查错误字典中是否添加了任何错误：

def clean(self, value):
    cleaned_data = self.cleaned_data

    if self._errors:
        self.data['password'] = 'abc'
        raise forms.ValidationError("You have failed validation!")
    else:
        return cleaned_data 

奖金！您可以检查特定字段上的错误：

def clean(self, value):
    cleaned_data = self.cleaned_data

    if self._errors and 'title' in self._errors:
        raise forms.ValidationError("You call that a title?!")
    else:
        return cleaned_data
