Yes of course.
Let's say we have following settings:
{{{
LANGUAGE_CODE = 'de-DE'
LANGUAGES = [
('en', 'English'),
('de', 'German'),
('es', 'Spanish'),
}}}
So we have German as standard language and the 3 languages in
`settings.LANGUAGES` as those which we want to have translated. And now
imagine we want to have a custom middleware that looks something like
this:
{{{
class CustomLocaleMiddleware(LocaleMiddleware):
def process_request(self, request):
super(CustomLocaleMiddleware, self).process_request(request)
lan = request.LANGUAGE_CODE
preference = translation.get_language_from_request(request,
support_all_languages=True)
if not settings.LANGUAGE_CODE.startswith(preference): #
Preference differs from LANGUAGE_CODE
translation.trans_real.translation(lan).add_fallback(
translation.trans_real.DjangoTranslation('en'))
}}}
So every language preference that gets identified by
`get_language_from_request` and differs from `settings.LANGUAGE_CODE` gets
English as fallback language, even if it's not in `settings.LANGUAGES`.
When you get e.g. ''pl'' as preference you get ''de'' as language, but
with ''en'' as fallback (that's what we want). With current Django you
would also get ''de'' as language, but no fallback because preference
would not be ''pl'' but ''de''. It would only work with "en", "de", and
"es".
