Edit our poll detail template (“polls/detail.html”), to be:

<form action="{% url 'polls:vote' %}" method="post">
{% csrf_token %}
    <legend><h1>{{ question.question_text }}</h1></legend>
    {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}
    {% for choice in question.choice_set.all %}
        <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ }}">
        <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br>
    {% endfor %}
<input type="submit" value="Vote">

Now, create a polls/templates/polls/results.html template and add the following code to it:

<h1>{{ question.question_text }}</h1>

{% for choice in question.choice_set.all %}
    <li>{{ choice.choice_text }} -- {{ choice.votes }} vote{{ choice.votes|pluralize }}</li>
{% endfor %}

<a href="{% url 'polls:detail' %}">Vote again?</a>

Now, go to /polls/1/ in your browser and vote in the question. You should see a results page that gets updated each time you vote.

Open the polls/ URLconf and change it like so:

from django.urls import path

from . import views

app_name = 'polls'
urlpatterns = [    path('', views.IndexView.as_view(), name='index'),    path('<int:pk>/', views.DetailView.as_view(), name='detail'),    path('<int:pk>/results/', views.ResultsView.as_view(), name='results'),    path('<int:question_id>/vote/',, name='vote'),]

To use Django’s generic views, open the polls/ file and change it like so:

from django.http import HttpResponseRedirect
from django.shortcuts import get_object_or_404, render
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):
    question = get_object_or_404(Question, pk=question_id)
        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.",
        selected_choice.votes += 1
        # 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=(,)))
