问题是我尝试撤消对编码所做的所有更改，但它仍然给我错误，我不知道原因。

以下是此错误所涉及的相关文件：

class QuizTake(FormView):
    form_class = QuestionForm
    template_name = 'question.html'

    def dispatch(self, request, *args, **kwargs):
        self.quiz = get_object_or_404(Quiz, url=self.kwargs['quiz_name'])
        if self.quiz.draft and not request.user.has_perm('quiz.change_quiz'):
            raise PermissionDenied

        self.logged_in_user = self.request.user.is_authenticated()

        if self.logged_in_user:
            self.sitting = Sitting.objects.user_sitting(request.user,
                                                        self.quiz)
        else:
            self.sitting = self.anon_load_sitting()

        if self.sitting is False:
            return render(request, 'single_complete.html')

        return super(QuizTake, self).dispatch(request, *args, **kwargs)

另一个片段：

def get_context_data(self, **kwargs):
        context = super(QuizTake, self).get_context_data(**kwargs)
        context['question'] = self.question
        context['quiz'] = self.quiz
        if hasattr(self, 'previous'):
            context['previous'] = self.previous
        if hasattr(self, 'progress'):
            context['progress'] = self.progress
        return context

还有forms.py：

from django import forms
from django.forms.widgets import RadioSelect, Textarea


class QuestionForm(forms.Form):
    def __init__(self, question, *args, **kwargs):
        super(QuestionForm, self).__init__(*args, **kwargs)
        choice_list = [x for x in question.get_answers_list()]
        self.fields["answers"] = forms.ChoiceField(choices=choice_list,
                                                   widget=RadioSelect)


class EssayForm(forms.Form):
    def __init__(self, question, *args, **kwargs):
        super(EssayForm, self).__init__(*args, **kwargs)
        self.fields["answers"] = forms.CharField(
            widget=Textarea(attrs={'style': 'width:100%'}))

是的，有人能帮帮我吗？我真的不知道如何解决它。

实例化时，您需要将question传递给QuestionForm。这可能应该在您的视图的get_form_kwargs方法中完成。
