1.编写更多的视图

打开polls/views.py文件，输入以下内容：

def detail(request, question_id):    return HttpResponse("You're looking at question %s." % question_id)def results(request, question_id):    response = "You're looking at the results of question %s."    return HttpResponse(response % question_id)def vote(request, question_id):    return HttpResponse("You're voting on question %s." % question_id)

2.添加app的urls配置

打开polls/urls.py文件，输入以下内容：

from django.conf.urls import urlfrom . import viewsurlpatterns = [    # ex: /polls/    url(r'^$', views.index, name='index'),    # ex: /polls/5/    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),    # ex: /polls/5/results/    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),    # ex: /polls/5/vote/    url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),]

注：看得出来上面的url是支持正则的，后面的views.xxx代表views.py中的相应方法

3.添加views方法

打开polls/views.py文件，输入以下内容：

from django.http import HttpResponsefrom .models import Questiondef index(request):    latest_question_list = Question.objects.order_by('-pub_date')[:5]    output = ', '.join([q.question_text for q in latest_question_list])    return HttpResponse(output)# Leave the rest of the views (detail, results, vote) unchanged

4.启动runserver

python manage.py runserver

打开http://127.0.0.1:8000/polls/ 可以看到页面效果
