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 1: The full error message is at http://dpaste.com/166201/

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'),
)

Answer 1

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

Answer 2

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. ;)
