Я пытаюсь прочитать значение из radio.input в приведенной ниже форме, используя
def question_detail(request,question_id,quiz_id):
q = Quiz.objects.get(pk = quiz_id)
que = Question.objects.get(pk = question_id)
count = q.question_set.count()
try:
selected_choice = que.answer_set.get(pk=request.POST['choice'])
except(KeyError, Answer.DoesNotExist):
come = que.rank
came = come + 1
later_question = q.question_set.get(rank=came)
return render(request, 'app/question_detail.html',{'que': que, 'count': count, 'later_question': later_question})
else:
if selected_choice.correct is True:
try:
come = que.rank
came = come + 1
later_question = q.question_set.get(rank=came)
except:
come = que.rank
came = come
later_question = q.question_set.get(rank=came)
else:
come = que.rank
later_question = q.question_set.get(rank=come)
return render(request, 'app/question_detail.html',{'count': count, 'que': que, 'later_question': later_question})
, но когда я пытаюсь получить доступ к веб-странице, он выдает Keyerror, пожалуйста, помогите
<form action="{% url 'app:detail' quiz_id=que.quiz.id question_id=later_question.id%}" method="post">{% csrf_token%}
{% for choice in que.answer_set.all %}
<input type="radio" name='choice' value="{{choice.id}}">
<label>{{choice.answer}}-{{choice.correct}}-{{choice.rank}}</label><br>
{% endfor %}
