Question

我是一个完整的Django新手，我正在按照教程：

https://docs.djangoproject.com/en/1.11/intro/tutorial01/

我到了舞台：

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

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

在mysite / urls.py中，但是当我这样做时：

python manage.py runserver

我在地址

的浏览器中收到404错误

http://localhost:8000/polls/

我正在使用python 2.7.6和Django 1.11.5

我的urls.py是

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

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

在终端会话中我得到了

Not Found: /polls/
[05/Oct/2017 12:25:22] "GET /polls/ HTTP/1.1" 404 1951

我在浏览器中加载网页

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls',
]

有人可以指出可能出现的问题吗？

Answer 1

在mysite/settings.py上添加INSTALLED_APPS：

INSTALLED_APPS = [
    ...<other installed apps>..
    'polls',
]

对于最新的django版本，建议添加：

INSTALLED_APPS = [
    ...<other installed apps>..
    'polls.apps.PollsConfig',
]

输入mysite/urls.py（您在此处发布的那个）：

from django.conf.urls import include, url
from django.contrib import admin    
urlpatterns = [
    url(r'^polls/', include('polls.urls')),
    url(r'^admin/', admin.site.urls),
]

在polls/urls.py ::

中

from django.conf.urls import url
from . import views    
urlpatterns = [
    url(r'^$', views.index, name='index'),
]

Answer 2

通过遵循教程here，对于遇到此问题的初学者，明确答案，项目根URLconf是与settings.py在同一文件夹中的那个：

mysite/mysite/urls.py

确保import 'include'。代码如下：

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

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

所以在mysite / mysite / settings.py中：

该行应为：

ROOT_URLCONF = 'mysite.urls'

您不需要创建全新的新根URL。
