Django教程-查看详情时轮询错误404

Question

我正在关注 https://docs.djangoproject.com/en/1.8/intro/tutorial03/ 我已经按照教程中完成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，我在 views.py 中定义了详细信息、结果、投票，在项目目录 urls.py 中定义了 urls.py 中的投票 url。当我访问

localhost:8000/民意调查/

有效。但是，当我尝试按照他们的描述访问民意调查的详细信息时，它会抛出 404.I 尝试了我的实际问题 ID，但一切都是徒劳的。
在文档中，他们说“在“/polls/34/”。它会运行 detail() 方法” 但对我来说它抛出 404

本地主机:8000/polls/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.

这是我的 urls.py 位于 ProjectName/ProjectName/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)),

]

这是我的投票 urls.py 位于 ProjectName/polls/urls.py

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'),
]

这是我的投票视图

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 /）：

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

而不是：

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

希望对您有所帮助！检查 tutorial page :)

Answer 2

对我来说，以下效果很好

path(r'projectapp', include('projectapp.urls')),
