No module named urls

Question

I'm following the Django Tutorials, I'm at the end of part 3, at Decoupling the URLconfs, at http://docs.djangoproject.com/en/1.1/intro/tutorial03/#intro-tutorial03 and I'm getting a "No module named urls" error message.

When I change:

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('mysite.polls.views',
    (r'^polls/$', 'index'),
    (r'^polls/(?P<poll_id>\d+)/$', 'detail'),
    (r'^polls/(?P<poll_id>\d+)/results/$', 'results'),
    (r'^polls/(?P<poll_id>\d+)/vote/$', 'vote'),
    (r'^admin/', include(admin.site.urls)),
)

to:

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

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

I changed include('mysite.polls.urls')), to include(mysite.polls.urls)),, but it still didn't work.

How to solve this problem?

UPDATE 2: at mysite/polls/urls.py is

from django.conf.urls.defaults import *

urlpatterns = patterns('mysite.polls.views',
    (r'^$', 'index'),
    (r'^(?P<poll_id>\d+)/$', 'detail'),
    (r'^(?P<poll_id>\d+)/results/$', 'results'),
    (r'^(?P<poll_id>\d+)/vote/$', 'vote'),
)

UPDATE 4: the whole project is at

Answer 1

I had a similar problem in my project root ... django complained that it couldn't find the module mysite.urls.

Turns out my ROOT_URLCONF variable in settings.py, which was set up using the default values, was set incorrect. Instead of "mysite.urls", it should have been simply "urls"

I changed it, and voila, it worked.

I can't re-produce the import error on my machine using your project files (Windows 7, Django 1.1.1, Python 2.6.4). Everything imported fine but the urls were not specified properly (like the tutorial shows). Fixing the code:

/mysite/urls.py:

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

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

/mysite/polls/urls.py:

from django.conf.urls.defaults import *

urlpatterns = patterns('mysite.polls.views',
    (r'^$', 'index'),
    (r'^(?P<poll_id>\d+)/$', 'detail'),
    (r'^(?P<poll_id>\d+)/results/$', 'results'),
    (r'^(?P<poll_id>\d+)/vote/$', 'vote'),
)

Visit http://127.0.0.1:8000/polls/ - I received a TemplateDoesNotExist exception because the template file is missing.

I'm afraid my answer might be to reboot and try it again. ;)

Answer 3

Is there an __init__.py inside mysite/polls/ directory?

Answer 4

I did exactly the same thing. Python newbie mistake by reading ahead. I created a file call "polls.url" thinking it was some sort of special django template file.

I misunderstood the text: "Now that we've decoupled that, we need to decouple the polls.urls URLconf by removing the leading "polls/" from each line, and removing the lines registering the admin site. Your polls.urls file should now look like this: "

It should really read: "Now that we've decoupled that, we need to decouple the polls.urls URLconf by removing the leading "polls/" from each line, and removing the lines registering the admin site. Your polls/urls.py file should now look like this: "

Answer 5

I also had a weird problem with "No module named mysite.urls". The admin site was down and the my whole site.

The solution, after a few hours of searching the web, was on my side : Django is caching some of the settings in a file that he knows from an environment variable.

I just closed my terminal in which i was doing the runnserver thing and opened a new one.

Late to the party but I fixed my problem by correcting a typo inside settings.py INSTALLED_APPS. I had 'webbapp' instead of 'webapp' so you might want to check on that as well (for people still having the problem)
