Description

I am trying to add translations for a new language (that Django doesn't support) to my project. Let's say it has the language code xxx for example.

I make the .po file with

./manage.py makemessages -l xxx

Then I translate the po file and compile it. When I set LANGUAGE_CODE = 'xxx' and run runserver, Django fails with:

Traceback (most recent call last):

It seems that this errors happens whenever you try to use a language that doesn't have a django.po shipped with django (in django/conf/locale/). Shouldn't I be able to provide the translations just in my project?

Maybe you need to add it to settings.LANGUAGES too?

comment:2 Changed 4 years ago by Gavin Wahl

It happens whether or not the language is in LANGUAGES.

comment:3 Changed 4 years ago by Tim Graham

Could you provide a minimal project to reproduce or a test case for the Django test suite?
