Question

所以这是我的表格：

class QuestionForm(forms.ModelForm):
    answer = forms.ChoiceField(required=True, widget=forms.RadioSelect())

    def __init__(self, question=None, *args, **kwargs):
        super(QuestionForm, self).__init__(*args, **kwargs)
        self.fields['answer'].choices = [(a.answer, a.answer) for a in Answer.objects.filter(question=question)]

    class Meta:
        model = Questions
        fields = ('answer', 'importance' )

当用户选择answer时，它会显示所有Answer个对象。以下是我的观点：

def questions(request):
    new_forms = []
    q = Questions.objects.all()[0]
    if request.method =='POST':
        #form = QuestionForm(request.POST or None)
        for forms in new_forms:
            if forms.is_valid():
                new = forms.save(commit=False)
                #get the user's inputs to the QuestionForm and save them
                UserAnswer(user=request.user, answer=new.cleaned_data['answer'], question=new.question)
                UserAnswer.save()

    else:
        instance=Questions.objects.all().filter(owner=request.user)[0]
        #form = QuestionForm(question=q, instance=q)

    for a in Questions.objects.all():
        new_forms.append(QuestionForm(question=a, instance=a))
    return render_to_response("questions/base.html", locals(), context_instance=RequestContext(request))

Answer 1

我对你正在做的事情感到很困惑。

            print new.fields['id_answer_2'].value
            print get_id_answer_2_display()

您save(commit=False)返回模型实例的ModelForm。它甚至不应该有一个fields属性（你会在这里得到一个AttributeError）。

2：你接下来打电话get_id_answer_2_display()，它似乎不是正确的字段（更别提你把它称为独立功能）。

您的ModelForm建议您使用answer字段，因此要使用get_FOO_display，您需要致电new.get_answer_display()

Django get_FOO_display自定义表单不起作用
