使用 django 验证带有引发错误的表单

Question

我正在尝试验证表单，用户无法通过表单发送联系信息，为此，我有：

class ActualizarCotizacionForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(ActualizarCotizacionForm, self).__init__(*args, **kwargs)
        for field_name, field in self.fields.items():
            field.widget.attrs['class'] = 'form-control'
            self.fields['proposal'].widget.attrs['rows'] = '4'
            self.fields['deliverable'].widget.attrs['rows'] = '4'

    class Meta():
        model = AffiliateQuote
        fields = ['proposal','deliverable','delivery_time','fee']


    def clean(self):
        data = self.cleaned_data['proposal']
        if "311" in data:
            raise forms.ValidationError("You cant send phone numbers through the form")
        return data

在模板中，我在 proposal 字段上方有这一行：{{form.proposal.errors.as_text}}

我放在这里的验证“311”只是一个例子，但是有了这个，我无法让它工作，我在proposal字段中写了“311”并且错误没有显示，我该如何实现这个?

好吧，把这个验证放在clean_proposal方法中，例如：

def clean_proposal(self):
        data = self.cleaned_data['proposal']
        if "311" in data:
            raise forms.ValidationError("You cant send phone numbers through the form")
        return data
