渲染时捕获KeyError：'phone_mobile'

forms.py 

class UserCreateProfileForm(forms.ModelForm):
    phone_daytime = forms.IntegerField(required=False)
    phone_mobile = forms.IntegerField(required=False)
    class Meta:
        model = UserProfile
        fields = ['phone_daytime', 'phone_mobile']
def clean(self):
    cleaned_data = self.cleaned_data
    phone_daytime = cleaned_data.get('phone_daytime')
    phone_mobile = cleaned_data.get('phone_mobile')

    if not any([phone_daytime, phone_mobile]):
        self._errors['phone_daytime'] = self.error_class(['Enter a valid phone number'])
        del self.cleaned_data['phone_daytime']
        self._errors['phone_mobile'] = self.error_class(['Enter a valid phone number'])
        del self.cleaned_data['phone_mobile']
    return cleaned_data

template.py 

 <tr>
     <td>Daytime phone:</td><td>{{ form.phone_daytime }}{{ form.phone_daytime.errors }}</td>
  </tr>
  <tr>
     <td>Mobile phone:</td><td>{{ form.phone_mobile }}{{ form.phone_mobile.errors }}</td>
  </tr>

当我在“phone_daytime”字段中输入一些字符时，我收到此错误“Caught KeyError while rendering: 'phone_mobile'”。来自所有其他验证的设备正在运行。

Exception Value: Caught KeyError while rendering: 'phone_mobile'

实际上它应该通过错误消息，因为phone_daytime和phone_mobile都被声明为IntegerField。但这会产生上述错误。需要帮助。

因为当你不在phone_mobile中输入任何内容时，它将不会存在于cleaning_data中，你试图从那里删除它，所以你会得到这个错误

答案 1 :(得分：1)

Deleting以下行清除了上述错误，validation也无问题

 del self.cleaned_data['']
