ERROR PAGE 

Using the URLconf defined in guide.urls, Django tried these URL patterns, in this order:
^$ [name='index']
^yapilacaklar/(?P<id>[0-9]+){0,1}?\/{0,1}(?P<process>[A-Za-z]+)$ [name='todo_list']
^admin/

MY URL PATTERN

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

 url(r'^yapilacaklar/(?P<id>[0-9]+){0,1}?\/{0,1}(?P<process>[A-Za-z]+)$','todo.views.todo_list', name='todo_list')

url(r'^admin/', include(admin.site.urls)),
)

thanks you very much...
