Hi,
I don't think that the 'including' URLs part forms a problem here.
For the given example, it should be easily doable
> from django.conf.urls import simple_url
> from . import views
> urlpatterns = [
> simple_url('articles/2003/', views.special_case_2003),
> simple_url('articles/:year)/', views.year_archive),
> simple_url('articles/:year/:month/', views.month_archive),
> simple_url('articles/:year/:month/:day/', views.article_detail),
> ]
The following should make it possible:
import re
def simple_url(route, view, *args, **kwargs):
regex_route = re.escape(route)
regex_route = re.sub(r':([A-Za-z0-9_-]+)', r'(?P<\1>[^/]+)',
regex_route)
# Anchor it to the beginning.
regex_route = '^' + regex_route
if not isinstance(view, (list, tuple)):
# It's not an include...
regex_route += '$'
return url(regex_route, view, *args, **kwargs)
(Not 100% tested, but I tested the re.sub ;) ).
So I think it is at least possible. Whether or not it's desirable though
is another question which I think I'm not suited to answer.
Kind regards,
Sjoerd Job
