I am going throught the Django tutorial here:
https://docs.djangoproject.com/en/1.10/intro/tutorial01/
I follow the instructions exactly. But when I try to go to http://localhost:8000/polls/, I don't see the message “Hello, world. You’re at the polls index.” as expected. Instead, I get the following error:
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.
Here is my mysite/urls.py file. I am not sure why the first regex pattern in urlpatterns is not recognized.
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),
]
You might have forgot .html extension in views.py while requesting the page.
I've run into a problem configuring the url.py files in a new project. I have one app, which contains two views. The first view should appear at myurl.com, while the other should appear at myurl.com/foo. myurl.com appears without trouble but myurl.com/foo shows a 404 page not found error.
The url.py at the project level looks like this:
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^$', include('myapp.urls', namespace="myapp")),
)
And the url.py at the app level looks like this:
from django.conf.urls import patterns, include, url
from myapp import views
urlpatterns = patterns('',
url(r'^$', views.book_search, name='book_search'),
url(r'^foo/', views.myapp, name='myapp')
)
I understand that that django is taking the URL that is submitted and checks it against the url patterns defined at the project level, but I don't know how to direct it to myapp without hosting all of myapp at some url that is not at the root, i.e. myapp.com/bar and myapp.com/bar/foo.
url(r'^$', include('myapp.urls', namespace="myapp")),
Remove the ^$ here. This would force all included URLs to match only if starting with "the end", i.e. nothing.
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'^$', views.index, name='index'),
)
mySite/polls/views.py:
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. You're at the polls index.")
mySite/settings.py:
...
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
)
....
ROOT_URLCONF = 'mySite.urls'
The error I'm getting:
Using the URLconf defined in mySite.urls, Django tried these URL patterns, in this order: ^admin/
The current URL, polls, didn't match any of these.
I had the same problem.
It turns out I was confused because of the multiple directories named "mysite".
I wrongly created a urls.py file in the root "mysite" directory (which contains "manage.py"), then pasted in the code from the website.
To correct it I deleted this file, went into the mysite/mysite directory (which contains "settings.py"), modified the existing "urls.py" file, and replaced the code with the tutorial code.
In a nutshell, make sure your urls.py file is in the right directory.
Django unable to resolve 127.0.0.1:8000/polls because url config defined as r'^polls/'.
Usual workaround:
mySite/urls.py:
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^polls/', include('polls.urls')),
)
Note:
Whenever Django encounters include(), It chops off whatever part of the URL matched up to that point and sends the remaining string to the included URLconf for further processing.
mySite/polls/urls.py:
from django.conf.urls import patterns, url
from polls import views
urlpatterns = patterns('polls.views',
url(r'^$', 'index', name='index'),
)
Note: Instead of typing that out for each entry in urlpatterns, you can use the first argument to the patterns() function to specify a prefix to apply to each view function.
Answer If
If you want to access 127.0.0.1:8000/polls Note: without trailing slash
use view based url
url(r'^polls', 'polls.views.index', name='index'),
So now you can access 127.0.0.1:8000/polls without trailing slash.
You're accessing to http://yourdomain.com/, and you don't have any URL defined for "/".
You have two options:
If you want to access to the index page of your polls application you have to enter the URL: yourdomain.com/polls
You can also modify you mySite/urls.py file to access from just yourdomain.com
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^$', include('polls.urls')),
)
To make the answer clear for beginners who has this issue by following the tutorial, the project root URLconf is the one in the same folder as settings.py which is:
mysite/mysite/urls.py
Just make sure import 'include'. The code looks like:
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')),
]
So in
mysite/mysite/settings.py:
The line should be:
ROOT_URLCONF = 'mysite.urls'
You don't need create a fresh new root URLconf.
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"

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
Another way to access 127.0.0.1:8000/polls would be to redirect the browser when accessing 127.0.0.1:8000. It is done by editing .../mysite/mysite/urls.py as follows:
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'),
]
Page not found?
If you get an error page here, check that you’re going to http://localhost:8000/polls/ and not http://localhost:8000/.

Actually the problem is that you didn't notice that
mysite/urls.py and polls/urls.py are two different files and you modified polls/urls.py instead of putting mysite/urls.py in the urls.py file in ...mysite\mysite folder.
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.
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.
2017-10-05_12:03 ~/mysite/mysite
$ vi urls.py
2017-10-05_12:04 ~/mysite/mysite
$ cd ../..
2017-10-05_12:04 ~
$ mv mysite SENSIBLE_NAME_DJANGO_ROOT
i had the same issue and got it resolved by adding /polls after http://server:port/ and so final address in server looks like:
http://server:port/polls
I am trying to display contents of a static page in Django project.
urls.py :-
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'spollow.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
(r'^$', 'django.views.generic.simple.direct_to_template', {'template': 'index.html'}),
url(r'^admin/', include(admin.site.urls)),
)
index.html is in the same directory as urls.py
I am getting 500 internal server error. Any ideas where I am going wrong?
First of all, what is the stacktrace from the 500 error saying that the error may be? You may be using Django 1.6 and the call to direct_to_template is deprecated.
On Django 1.5 or newer you can use TemplateView
Here's the example from the documentation
https://docs.djangoproject.com/en/dev/topics/class-based-views/
from django.conf.urls import patterns
from django.views.generic import TemplateView
urlpatterns = patterns('',
(r'^about/', TemplateView.as_view(template_name="about.html")),
)
You can use the direct_to_template view on Django 1.4 or older
Here's the relevant documentation
https://docs.djangoproject.com/en/1.4/ref/generic-views/#django-views-generic-simple-direct-to-template
from django.views.generic.simple import direct_to_template
urlpatterns = patterns('',
(r'^foo/$', direct_to_template, {'template': 'foo_index.html'}),
(r'^foo/(?P<id>\d+)/$', direct_to_template, {'template': 'foo_detail.html'}),
)
If it is the latter, I would use a module instead of string, (look at the import on the example).
Other than that, without the 500 details it will be shooting in the dark, you may not have the right template, or an incorrect path, or a million different things.
Bonus note
If you just want to serve static pages, it might be better to serve them through the actual webserver in front of django (nginx, apache, etc), specially if you are expecting a high volume of traffic.
If Your error is due to unable to find index.html
if yours is an app(ie: created by python manage.py startapp <app>) then:
Then django will search for template files in <app>/templates directory, if you added the app to INSTALLED_APPS in settings.py.
so you need to create a folder templates inside your <app> and put index.html inside it.
if you don't have any apps, you want to add the template path manually :
open settings.py, then edit TEMPLATE_DIRS
TEMPLATE_DIRS = (
# Put the full path of the template dir here, like "/home/html/django_templates" or
# "C:/www/django/templates".
)
In Django 1.5 or newer you can use the render function instead of direct_to_template:
from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
url(r'^$', 'django.shortcuts.render', {'template_name': 'index.html'}),
)
Or if you prefer the more complex way :), you can use class-based TemplateView:
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView
urlpatterns = patterns('',
url(r'^$', TemplateView.as_view(template_name="index.html")),
)
I'm designing a photo app .
I get this error every time I view an uploaded picture on my admin page.
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/media/images/California_Poppy.jpg
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^polls/
^admin/
^cool/
^forum/
^register/
The current URL, media/images/California_Poppy.jpg, didn't match any of these.
My current settings are :
MEDIA_ROOT = 'C:/djcode/mysite/photo'
MEDIA_URL = 'http://127.0.0.1:8000/media/'
I reckon the problem is with these settings. I'm using window btw
The Django docs have a solution for you to serve media in development. Usually in production you alias your media directory to be served directly from your web server to be more efficient. To serve in development, the docs show two different solutions. You can check out the provided link to read the docs and figure out which one would be better for you.
from django.conf import settings
# ... the rest of your URLconf goes here ...
if settings.DEBUG:
urlpatterns += patterns('',
url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {
'document_root': settings.MEDIA_ROOT,
}),
)
OR
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = patterns('',
# ... the rest of your URLconf goes here ...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
