Well as far I can test, Django i18n does supports fall-back 'xx-YY' to 'xx' then to default ('en' in my case) but only for 'Accept-Language' user agent header. It does not do same for URL language switch.
Here is the solution I could come up with: from django.views.generic import RedirectViewfrom django.conf import settings... urlpatterns += patterns('', url(r'^(?P<lang>[a-z]{2})-[A-Za-z]{2}/(?P<path>.*)$', RedirectView.as_view(url='/%(lang)s/%(path)s',query_string=True)), url(r'^[a-z]{2}/(?P<path>.*)$', RedirectView.as_view(url='/{}/%(path)s'.format(settings.LANGUAGE_CODE),query_string=True)),) - Any xx-YY not handled by i18n pattern redirected to xx - Any xx not handled by i18n pattern redirected to default language set using LANGUAGE_CODE. -- You received this message because you are subscribed to the Google Groups "Django users" group.
