{{{
#!python
  url(r'(?u)^foo/(?P<id>\d+)/$', name='foo-url')
}}}

and then use django.core.urlresolvers.reverse to construct a url with parameters:

{{{
#!python
  reverse('foo-url', kwargs=dict(id=12))
}}}

I get a NoMatchError here (not enough positional arguments), but I don't if I remove the flag group at the beginning of the url regexp.

I've attached a small patch for this issue ; the Python re docs state that a flag group should be the first non-whitespace content in the regexp, so I only cover that case."		closed	Core (Other)	dev		wontfix			Ready for checkin	1	0	0	0	0	0
