Django get_absolute_url from cms page

Question

I want to access to the url from a cms page

from cms.models import Page

page = Page.objects.published()[3]   #clinics page
print page.get_absolute_url()

But it shows this error:

ImproperlyConfigured at /en/clinics/ 
The included urlconf urls doesn't have any patterns in it

Clinics page works (admin + frontend), the problem is when I try to call get_absolute_url()

part of urls.py:

urlpatterns += i18n_patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^', include('cms.urls')),
)

clinics/urls.py:

from django.conf.urls import patterns, url
from clinics import views

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

Answer 1

I found another way to do it and it works. Calling the reverse of the clinic_list route directly. I think the way of passing through the cms page is not necessary.

from django.core.urlresolvers import reverse

print reverse('clinic_list')

Answer 2

page = Page.objects.published()[3]

This won't work, as published is a BooleanField from the model Page.

What you want to do is:

page = page.objects.get(pk=3) # At least if this pk is 3, check with your installation.
page.get_absolute_url()
