python - Can't get django urls to work -


i've got simple django setup in have 1 app called 'lists'. want http://127.0.0.1:8000/lists show app. changed main urls.py following:

from django.conf.urls import patterns, include, url  django.contrib import admin admin.autodiscover()  urlpatterns = patterns('',     url(r'^lists/', include('lists.urls')),     url(r'^admin/', include(admin.site.urls)), )

and changed urls.py resides in lists-folder (my app called lists) following:

from django.conf.urls import patterns, url lists import views  urlpatterns = patterns(     url(r'^$', views.index, name='index') )

as far know following instructions in the django tutorial well, when visit http://127.0.0.1:8000/lists (without trailing slash) gives me following error:

page not found (404) request method:    request url:    http://127.0.0.1:8000/lists  using urlconf defined in companylists.urls, django tried these url patterns, in order:      ^lists/     ^admin/  current url, lists, didn't match of these.

and when visit http://127.0.0.1:8000/lists/ (with trailing slash) gives me following error:

page not found (404) request method:    request url:    http://127.0.0.1:8000/lists/  using urlconf defined in companylists.urls, django tried these url patterns, in order:      ^admin/  current url, lists/, didn't match of these.

i don't understand why doesn't search ^lists/ anymore when visit url trailing slash. know doing wrong here?

all tips welcome!

you're missing empty string @ start of patterns in lists urls.py.

try this:

urlpatterns = patterns('',     url(r'^$', views.index, name='index') )

the blank string view prefix can use assist dry principal. used prefix views path.

for example, (extending example above):

rather having:

urlpatterns = patterns('',     url(r'^$', views.index, name='index'),     url(r'^homepage$', views.homepage, name='index'),     url(r'^lists$', views.lists, name='index'),     url(r'^detail$', views.detail, name='index'), )

you can use:

urlpatterns = patterns('views',     url(r'^$', index, name='index'),     url(r'^homepage$', homepage, name='index'),     url(r'^lists$', lists, name='index'),     url(r'^detail$', detail, name='index'), )

to have multiple view prefixes segment urlpatterns.

urlpatterns = patterns('views',     url(r'^$', index, name='index'),     url(r'^homepage$', homepage, name='index'),     url(r'^lists$', lists, name='index'),     url(r'^detail$', detail, name='index'), )  urlpatterns += patterns('more_views',     url(r'^extra_page$', extra_page, name='index'),     url(r'^more_stuff$', something_else, name='index'), )
