python - 在表单集中设置 auto_id 并且不要在首次显示时禁用错误

Question

我正在编写以下表单的 View :

class QuestionForm(forms.ModelForm):
    class Meta:
        model = Question
        fields = ('question_text',)

    def __init__(self, *args, **kwargs):
        super().__init__(args, kwargs)
        self.fields['question_text'].label = 'Question'


class ChoiceForm(forms.ModelForm):
    class Meta:
        model = Choice
        fields = ('choice_text',)

    def __init__(self, *args, **kwargs):
        super().__init__(args, kwargs)
        self.fields['choice_text'].label = 'Choice'


ChoiceFormSet = inlineformset_factory(Question, Choice, form=ChoiceForm,
                                       extra=6, validate_min=1, can_delete=False)

def create_question(request):
    if request.method == "POST":
        question_form = QuestionForm(request.POST)
        choice_formset = ChoiceFormSet(request.POST)
        if question_form.is_valid() and choice_formset.is_valid():
            question = question_form.save()
            choice_formset.instance = question
            choice_formset.save()
            return HttpResponseRedirect(reverse('polls:vote', args=(question.id,)))
    else:
        question_form = QuestionForm()
        choice_formset = ChoiceFormSet()

    question_form.auto_id = False
    question_form.use_required_attribute = False

    for form in choice_formset:
        form.auto_id = False
        form.use_required_attribute = False

    return render(request, 'polls/create.html', {'question_form': question_form, 'choice_formset': choice_formset})

• 首次显示 View 时也会显示字段必填错误消息

• 表单要求填写所有选项，但只能是一个:validate_min=1

• auto_id和use_required_attribute如何设置更优雅？

Answer 1

• 该表单始终处于绑定(bind)状态，因此该表单无效。我忘记了 super call (super().__init__(*args, **kwargs)) 形式中的星号
• 采用上述解决方案后，验证也有效

• 表单集还具有 auto_id 属性，并且默认情况下禁用 use_required_attribute:

  question_form.auto_id = False
  choice_form_set.auto_id = False
  question_form.use_required_attribute = False
