I have setup part 1 of the django tutorial and am receiving the following 'Page not found (404)' error when trying to access the polls app:

Error Message

Page not found (404)
  Request Method:   GET
  Request URL:  http://proto.slc.venturedata.com/polls/
  Raised by:    polls.views.index

Using the URLconf defined in proto.urls, Django tried these URL patterns, in this order:
  1. polls/
  2. admin/

The empty path didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

I'm using Django 2.2, Python 3.7, Apache 2.4.6, mod-wsgi 4.6.5.

I was able to complete the tutorial using the built in web server, but I started running into problems when I added Apache and mod-wsgi into the mix. Here is my code:


from django.contrib import admin
from django.urls import include, path

urlpatterns = [
  path('polls/', include('polls.urls')),
  path('admin/', admin.site.urls),


from django.urls import path
from . import views

urlpatterns = [
  path('', views.index, name='index'),


from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

The only thing changed in the settings.py was the TIMEZONE. Everything else is set to defaults.

Something seems to be up with the urls and path matching. The url I used (proto.slc.venturedata.com/polls/) should match the 'polls/' path, but the error message says that the path is empty.

In experimenting I found that I didn't receive an error if I modified proto/urls.py by replacing the 'polls/' path with an empty path: ''.

urlpatterns = [
  path('', include('polls.urls')),
  path('admin/', admin.site.urls),

Am I missing something?

Including the non-default Apache configuration since the problems started after I configured Django to use Apache as the webserver.

<Directory />
  AllowOverride none
  Require all denied
DocumentRoot "/var/www/html"

WSGIPythonPath /var/local/www/proto/

<VirtualHost *:80>
    DocumentRoot "/var/local/www/proto"
    ServerName proto.slc.venturedata.com

    <Directory "/var/local/www/proto">
            Require all granted

    WSGIScriptAlias /polls /var/local/www/proto/proto/wsgi.py

Daniel Roseman suggested I include my Apache configuration. As I was adding the configuration parameters to this post I saw the error in the Virtual Host configuration. WSGIScriptAlias is the culprit.


WSGIScriptAlias /polls /var/local/www/proto/proto/wsgi.py

Should Be:

WSGIScriptAlias / /var/local/www/proto/proto/wsgi.py

After making the configuration change the tutorial is working as expected.

Sometimes it just takes someone looking over your shoulder.
