can you check what is wrong with def vote(request, question_id), i am not able to run server. The exceptions and my views.py code are wrriten below:

Views.py:

from django.shortcuts import get_object_or_404, render

from django.http import HttpResponseRedirect

from django.urls import reverse

from django.views import generic

from . models import Choice, Question

class IndexView(generic.ListView):

template_name = 'polls/index.html'

context_object_name = 'latest_question_list'

def get_queryset(self):

"""Return the last five published questions."""

return Question.objects.order_by('-pub_date')[:5]

class DetailView(generic.DetailView):

model = Question

template_name = 'polls/detail.html'

class ResultsView(generic.DetailView):

model = Question

template_name = 'polls/results.html'

def vote(request, question_id):

... # Same as above, no changes needed.

question = get_object_or_404(Question, pk=question_id)

    try:

        selected_choice = question.choice_set.get(pk=request.POST['choice'])

    except (KeyError, Choice.DoesNotExist):

        # Redisplay the question voting form.

        return render(request, 'polls/detail.html', {

            'question': question,

            'error_message': "You didn't select a choice.",

        })

    else:

        selected_choice.votes += 1

        selected_choice.save()

        # Always return an HttpResponseRedirect after successfully dealing

        # with POST data. This prevents data from being posted twice if a

        # user hits the Back button.

        return HttpResponseRedirect(reverse('polls:results', args=(question.id,)))
