1.編寫第一個視圖

打開polls/view.py

利用一個URLconf將這個視圖映射到URL上。

首先先創建一個urls.py文件

編寫polls/urls.py

編寫mysite/urls.py,讓主URLconf可以鏈接到polls.urls模塊。在mysite/urls.py中插入一個include()：

結果：

編寫更多的視圖

polls/view.py

 1 from django.shortcuts import render
 2 from django.http import HttpResponse
 3 
 4 def index(request):
 5     return
 
 HttpResponse("Hello,world.You‘re at the polls index.")
 6     
 7 def detail(request,question_id):
 8     return HttpResponse("You ‘ re looking at question %s. " % question_id)
 9     
10 def results(request,question_id):
11     response = "You‘re looking at the results of question %s."
12     return
 
 HttpResponse(response % question_id)
13 
14 def vote(request,question_id):
15     return HttpResponse("You‘re voting on question %s." % question_id)
16 
17 # Create your views here.

通過下面的url() 調用將這些新的視圖和polls.urls模塊關聯起來：

 1 from django.conf.urls import url
 2 
 3 from . import views
 4 
 5 urlpatterns = [
 
 6      # ex: /polls/
 7     url(r‘^$‘, views.index, name=‘index‘),
 8     # ex: /polls/5/
 9     url(r‘^(?P<question_id>[0-9]+)/$‘, views.detail, name=‘detail‘),
10     # ex: /polls/5/results/
11     url(r‘^(?P<question_id>[0-9]+)/results/$‘, views.results, name=‘results‘),
12     # ex: /polls/5/vote/
13     url(r‘^(?P<question_id>[0-9]+)/vote/$‘, views.vote, name=‘vote‘),
14 ]
