如何将一个变量从一个方法传递给另一个使用相同类的方法？

Question

如何在第一种方法（contect_data）的第二种方法（表格）中获得变量qid。

现在我收到错误：      NameError：name＆＃39; tmp＆＃39;未定义

class AnswerView(FormView):
    template_name = 'answer.html'
    form_class = AnsForm
    success_url='success'
    def get_context_data(self, *args, **kwargs):
        context = super(AnswerView,self).get_context_data(**kwargs)
        qid = self.kwargs['qid']
        print(qid)
        self.qid=qid
        q_obj = Quest.objects.get(id=qid)
        context['question'] = q_obj

        return context

   def form_valid(self, form):

       answ1 = form.cleaned_data['txta']

       tmp = self.get_context_data().qid
       obj4=Ans.objects.create(answer=answ1,status=0,questid=tmp)
       obj4.save()
       return super().form_valid(form)

Answer 1

实际上，您也可以在self.kwargs['qid']中使用form_valid。所以你可以这样做：

class AnswerView(FormView):
    template_name = 'answer.html'
    form_class = AnsForm
    success_url='success'

    def get_context_data(self, *args, **kwargs):
        context = super(AnswerView,self).get_context_data(**kwargs)
        qid = self.kwargs['qid']
        q_obj = Quest.objects.get(id=qid)
        context['question'] = q_obj

        return context

    def form_valid(self, form):

       answ1 = form.cleaned_data['txta']

       tmp = self.kwargs['qid']
       obj4=Ans.objects.create(answer=answ1,status=0,questid=tmp)
       obj4.save()
       return super().form_valid(form)

Answer 2

这样做的一种方法是将变量qid设置为您班级的数据成员，尽管我不确定这是否适合您的用例。这样两种方法都可以访问和修改它。希望这能解决你的问题。
