搭建自己的Django应用（3）Writing your first Django app, part 3

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 url

from . import views

urlpatterns = [
# 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'),
]
