Question

I already searched for everything I could, but this annoying error is still there. The admin interface (localhost:8000/admin/) works fine, but no one else. Obs.: Im using Apress – Practical Django Projects (2nd edition) to learn Django. I’ll post my code here so somebody can tell what I did wrong. Thanks!
Code:

settings.py

    # Django settings for cms project.

    TEMPLATE_DEBUG = DEBUG
    APPEND_SLASH = True
    ADMINS = (
        # ('Your Name', '[e-mail]'),

urls.py

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

    # Uncomment the next two lines to enable the admin:
    from django.contrib import admin
    admin.autodiscover()

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

PS: Everything is idented correctly. So if there are some identation mistakes, it’s because I did the copy/paste real quick.

Answer 1

You should not include flatpages in your url conf.

url(r'^admin/', include(admin.site.urls)),
url(r'', include('django.contrib.flatpages.urls')), # remove this 

That’s probably why you’re getting the error… as flatpages practically match any URL.

Normally flatpages work via the flatpage fallback middleware that will attempt to locate a flatpage IF no other urls match.
