Django cross-site reverse URLs

Question

Probably simple question and I\'m just missing something, but I\'m stuck out of ideas.

I have Django project serving several sites with distinct sessions.py

Answer 1

I've implemented it by overriding django.core.urlresolvers.reverse with my custom function:

from django.core import urlresolvers
from django.conf import settings

__real_reverse = urlresolvers.reverse

def reverse(viewname, urlconf=None, args=None, kwargs=None, prefix=None):
    try:
        return __real_reverse(viewname, urlconf, args, kwargs, prefix)
    except urlresolvers.NoReverseMatch, no_match:
        external_urlconfs = getattr(settings, 'EXTERNAL_URLCONFS', [])
        for p, c in external_urlconfs:
            c = urlresolvers.RegexURLResolver(r'^/', c)
            try:
                return p + c.reverse(viewname, *args, **kwargs)
            except urlresolvers.NoReverseMatch:
                pass
        raise no_match

urlresolvers.reverse = reverse

Then listing URLconfs in settings.py like this:

ROOT_URLCONF = 'project.urls_a'

EXTERNAL_URLCONFS = (
    ('http://b.example.com/', 'project.urls_b'),
)
