Page not found 404 on Django site?

Question

I'm following the tutorial on Django's site to create a simple poll app. However, Django is unable to resolve "//127.0.0.1:8000/polls" , even though I've defined the regex in mySite/urls.py. I'm doing this in a virtualenv, with the latest Django (1.7) installed.

mySite/urls.py:

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

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

mySite/polls/urls.py:

from django.conf.urls import patterns, url
from polls import views

urlpatterns = patterns('',
url(r'^$', views.index, name='index'), 
)

mySite/polls/views.py:

from django.shortcuts import render
from django.http import HttpResponse
def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

mySite/settings.py:

 ...
 INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
 ) 
  ....
 ROOT_URLCONF = 'mySite.urls'

The error I'm getting:

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.

Answer 1

Add the below line in your Mysite/urls.py

url(r'^$', views.index, name='index'),

and check. If you have created your project correctly, it should work. Else something like above might have happened to have more than one files so confused.

Answer 2

Depending on where you put your ROOT urls.py, you set your ROOT_URLCONFIG accordingly, if you have it in your outermost folder containing manage.py then "urls" is ok. if you have it in someother folder then you have to do ".urls"

Answer 3

You put the urls.py folder into the outer MySite folder, you are suppose to put it in the inner one so its not mySite/urls.py, but mySite/mySite/urls.py:

ran into the same mistake when i did the tutorial

Answer 4

In my case, it was a stupid mistake. I wanted to integrate the plugin django-tinymce, and test it. So following this guide, I did the step 3 and exported the variable to the path. As the server runned again, I received the not found error, showing the message:

Using the URLconf defined in testtinymce.urls, Django tried these URL patterns, in this order: ....

But I didn't know what exactly it was, until I remembered exporting the variable DJANGO_SETTINGS_MODULE

running unset DJANGO_SETTINGS_MODULE in terminal solved my issue. Hope that it helps someone too.

Answer 5

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

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^polls/', include('polls.urls', namespace='polls')),
    url(r'^$', views.index, name='index'),
]
