The current URL, app/, didn't match any of these
提问by Dhaval
I'm a newbie in Django and just started looking at it before a day by installing Django 1.10 on my local.
我是 Django 的新手，并在一天前通过在本地安装 Django 1.10 开始查看它。
I've followed all the instructions of this link https://docs.djangoproject.com/en/dev/intro/tutorial01/. However I'm continuously getting this error:
我已按照此链接https://docs.djangoproject.com/en/dev/intro/tutorial01/ 的所有说明进行操作。但是我不断收到此错误：
Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/polls/
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^admin/
The current URL, polls/, didn't match any of these.
I've created polls app to getting started.
我已经创建了民意调查应用程序以开始使用。
To make a start, I went with view.py, here is the code:
首先，我使用 view.py，这是代码：
polls/views.py
民意调查/views.py
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello World!")
Here is my code for urls.py:
这是我的 urls.py 代码：
polls/urls.py
民意调查/网址.py
from django.conf.urls import patterns, url
from . import views
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
)
And here is the urls.py in root:
这是根目录下的 urls.py：
mysite/urls.py
我的网站/urls.py
from django.conf.urls import patterns,include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^polls/', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),
)
I've spent good piece of time to find out the solution, found that this question has been asked for many times,so tried with those solutions as well but none of them worked for me.
我花了很多时间来找出解决方案，发现这个问题已经被问过很多次了，所以也尝试了这些解决方案，但没有一个对我有用。
I can't find out what I'm missing here so please draw my attention to the gap.
我找不到我在这里遗漏了什么，所以请让我注意这个差距。

I think you have edited the wrong file when trying to change the root url config.
我认为您在尝试更改根 url 配置时编辑了错误的文件。
Make sure you are editing the root url config in mysite/mysite/urls.py(the directory containing settings.py) not mysite/urls.py(the directory containing manage.py).
确保您在mysite/mysite/urls.py（包含 的目录settings.py）而不是mysite/urls.py（包含 的目录）中编辑根 url 配置manage.py。
As general advice, install the latest release, currently 1.9. Don't use 1.10, which is under development. Make sure that you are following the tutorial for 1.9, because the tutorial changes for different versions. For example, your mysite/urls.pydoesn't match the tutorial for 1.9, as the urlpatternsshould be:
作为一般建议，请安装最新版本，目前为 1.9。不要使用正在开发的 1.10。确保您遵循1.9的教程，因为教程会因不同版本而异。例如，您mysite/urls.py与 1.9 的教程不匹配，因为urlpatterns应该是：
urlpatterns = [
url(r'^polls/', include('polls.urls')),
url(r'^admin/', admin.site.urls),
]

In settings.pyyou have a setting name INSTALLED_APPS-
在settings.py你有一个设置名称 INSTALLED_APPS-
Adds you app i.e. pollsto it.
将您的应用程序添加polls到其中。
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
....
'polls',
]

I too had same problem going through the official docs tutorial. I was using cloud 9. What I realised before I was able to solve this problem was that while creating the workspace I already chose django(ie by the time my workspace was created, django had already been installed) And going through the tutorial, I again executed $ django-admin startproject mysitethereby having another layer of django with multiple directories and unavoidably the confusion. My solution was to delete everything and start all over.
我在阅读官方文档教程时也遇到了同样的问题。我使用的是 cloud 9。在我能够解决这个问题之前，我意识到在创建工作区时我已经选择了 django（即在我的工作区创建时，django 已经安装）并且通过教程，我再次执行，$ django-admin startproject mysite从而拥有另一层带有多个目录的 django，并且不可避免地出现了混乱。我的解决方案是删除所有内容并重新开始。
Since this problem is common to many people, I suggest that django tutorial docs should be more explicit on this.
由于这个问题对很多人来说都很常见，我建议 django 教程文档应该更明确地说明这一点。
I hope this help somebody.
我希望这对某人有帮助。

It's working. Go to your url bar and type your app name:
它正在工作。转到您的网址栏并输入您的应用名称：
http://127.0.0.1:8000/home
My app name is home. It will work.
我的应用程序名称是 home。它会起作用。
If you want to set your app as your default page then import views from your app.
如果您想将您的应用程序设置为默认页面，请从您的应用程序导入视图。
Like
喜欢
from home import views
then write
然后写
url(r'^$', views.index),
inside.
里面。
It will set the views as your default page
它将视图设置为您的默认页面
http://127.0.0.1:8000/
When you type this it will redirect to your views.
当您键入此内容时，它将重定向到您的视图。

I had the same problem as described. Running a Windows machine.
我遇到了与描述相同的问题。运行 Windows 机器。
It turned out, that the virtual environment I was using had not been configured properly (or maybe I had forgot to activate it before installing Django) and the interpreter and django-admin were fetched from the wrong path by CMD.EXE.
结果，我使用的虚拟环境没有正确配置（或者我可能在安装 Django 之前忘记激活它）并且解释器和 django-admin 被 CMD.EXE 从错误的路径中获取。
If it appears as if Django is "ignoring" your urls.py- try deleting everything, re-creating the virtual environment, activating it and re-installing Django afterwards.
如果看起来 Django 正在“忽略”您的urls.py- 尝试删除所有内容，重新创建虚拟环境，激活它并在之后重新安装 Django。
Hope this helps.
希望这可以帮助。

change the mysite/url
更改我的网站/网址
from django.conf.urls import patterns,include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^&', include('polls.urls')),
url(r'^admin/', include(admin.site.urls)),
)
Then run your server and visit 127.0.0.1/8000. This should take you to the index of ur website.
然后运行你的服务器并访问 127.0.0.1/8000。这应该带您到您网站的索引。
or you leave your code as it is and run 127.0.0.1/8000/polls on your browser
或者您保持代码不变并在浏览器上运行 127.0.0.1/8000/polls
