Django教程 - 查看详细信息时的轮询错误404

Question

我正在关注https://docs.djangoproject.com/en/1.8/intro/tutorial03/ 我已经按照教程中的方式配置了我的项目目录.我正在为民意调查配置网址.根据教程我定义了详细信息,结果,在投票的urls.py中的views.py和poll url中投票,这是在项目目录的urls.py中定义的.当我访问

本地主机:8000 /调查/

有用.但是,当我试图访问一个民意调查的细节,因为他们描述它抛出404.I我尝试了我的实际问题ID,但都是徒劳的.
在Docs中他们说"at"/ polls/34 /".它将运行detail()方法"但对我来说它会抛出404

本地主机:8000 /调查/ 34 /

Using the URLconf defined in DjangoFirst.urls, Django tried these URL patterns, in this order:
^polls ^$ [name='index']
^polls ^(?P<question_id>[0-9]+)/$ [name='detail']
^polls ^(?P<question_id>[0-9]+)/results/$ [name='results']
^polls ^(?P<question_id>[0-9]+)/votes/$ [name='vote']
^admin/
The current URL, polls/34/, didn't match any of these.

这是位于ProjectName/ProjectName/urls.py中的urls.py

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url (r'^polls', include('polls.urls')),
    url(r'^admin/', include(admin.site.urls)),

]

这是我的民意调查urls.py位于ProjectName/polls/urls.py中

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),
    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),
    url(r'^(?P<question_id>[0-9]+)/votes/$', views.vote, name='vote'),
]

这是我的民意调查

from django.http import HttpResponse


def index(request):
    return HttpResponse("Hello World")

def detail(request, question_id):
    return HttpResponse("You are looking at question %s." % question_id)

def results(request,  question_id):
    response =  "You are looking at response of question %s."
    return HttpResponse(response % question_id)

def vote(request, question_id):
    return HttpResponse("You are voting on question %s." % question_id)

我找不到我的代码有什么问题.请帮帮我？

Answer 1

我认为这是因为它应该是(在你的代码中它缺少一个/):

url(r'^polls/', include('polls.urls')),

代替:

url (r'^polls', include('polls.urls')),

希望这可以帮助!查看教程页面 :)
