Addition: Url convenience function

[Martin Owens]

We're using a convenience function in our website urls and I want to propose it's inclusion into django upstream. I'm sounding out developers feelings on such an addition before I generate a patch and connected documentation.

Code (for django.conf.urls):

def url_tree(regex, *urls):
    return url(regex, include(patterns('', *urls)))

This function cleans up url definitions that contain multiple layers. For example if you had a urls file containing:

urlpatterns = patterns('',
  url(r'^$', MyListView.as_view()),
  url(r'^(?P<pk>\d+)/$', MyItemView.as_view()),
  url(r'^(?P<pk>\d+)/delete/$', MyDeleteView.as_view()),
  url(r'^(?P<pk>\d+)/post/$', MyPostView.as_view()),
)

And DRY it into:

urlpatterns = patterns('',
  url(r'^$', MyListView.as_view()),
  url_tree(r'^(?P<pk>\d+)/',
    url('^$', MyItemView.as_view()),
    url(r'^delete/$', MyDeleteView.as_view()),
    url(r'^post/$', MyPostView.as_view()),
  ),
)

This function gets very useful with tens of possible functions and long urls. So. Does this make sense as an addition to django? Is the functionality already there an I've missed it? Let me know.

You can use include() for this, see the last example in ​https://docs.djangoproject.com/en/dev/topics/http/urls/#including-other-urlconfs.

It's a bit of a lisp there with all those brackets, but I guess it's better than RY. Thanks for the quick resolution.
