在完成（2）之后，我们来继续关注创建一个公开的界面——views

view是在你的Django网页中的实现特定功能大的页面，它有一个特殊的模板，比如，在一个博客app中，你可能需要以下的views：

Blog homepage

Entry “detail” page

Year-based archive page

Month-based archive page

Day-based archive page

Comment action

在polls应用中，我们有下面4个views

index

detail

results

vote

写更多的views

修改polls/views.py变为以下内容：

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)

修改polls.urls：

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'),]
