这是错误-无法分配“问题2”：Answers.question必须是问题实例

model.py

def main(request, pk):
ques = get_object_or_404(Question, pk=pk)
if request.method == "POST":
    answerForm = AnswerForm(request.POST)
    if answerForm.is_valid():
        ans = answerForm.save(commit=False)
        ans.user = request.user
        ans.question = Answers(question=ques.question) # here assigning foreign key
        ans.answer = answerForm.cleaned_data.get['question_sel']
        print(answerForm.cleaned_data.get['question_sel'])
        ans.save()
        return redirect('main', pk=ques.pk)
else:
    answerForm = AnswerForm(request.POST)
return render(request, 'quiz/main.html', {'ques': ques,'answerForm':answerForm})

您可能只想在这里使用ans.question=ques。ques是当前问题的实例，将保存到答案中

如果你想得到一个特定问题的答案，你需要做answer.objects.getquestion=ques，但在这种情况下没有意义
