from django.shortcuts import render
    from django.http import HttpResponse
    # Create your views here.
    def index(request):
        return HttpResponse('hello django polls index')
    
    def q_detail(request,question_id):

    def latest_question_list(request):
        latest_question_list = Question.objects.order_by('-published_time')[:5]
        template = loader.get_template('polls/index.html')
        context = {
        
            'latest_question_list': latest_question_list,
        }
        return HttpResponse(template.render(context, request))

## vim django-20231002/mysite/polls/urls.py ##

from django.urls import path
    from . import views
    
    urlpatterns=[
        path('index/',views.index,name='index'),
        path('<int:question_id>/',views.q_detail),
        # ex: /polls/5/results/
        path('<int:question_id>/results/', views.results, name='results'),
        # ex: /polls/5/vote/
        path('<int:question_id>/vote/', views.vote, name='vote'),
        path('latest_question_list/',views.latest_question_list,name='latest_question_list'),
    ]

## vim django-20231002/mysite/polls/templates/polls/index.html ##

{% if latest_question_list %}
        <ul>
        {% for question in latest_question_list %}
            <li><a href="/polls/{
         { question.id }}/">{

        {% endfor %}
        </ul>
    {% else %}
        <p>No polls are available.</p>
