#19811 closed Bug (fixed)

KeyError: u"Unknown language code 'en-us'."

Reported by: Max Arnold Owned by: nobody

Severity: Normal Keywords:

Description

Default LANGUAGE_CODE='en-us' is not present in django.conf.locale.LANG_INFO and can trigger KeyError exception. It can be easily reproduced by using get_language_info in templates. Example project is attached.

Command to reproduce an exception:

curl -v -L http://localhost:8000

Traceback is below:

Internal Server Error: /en-us/

I also think that we should fallback to the language code stripped from the country code in this case.

comment:2 by Max Arnold, 12 years ago

The bug exists not only in Django-1.5rc1, but also Django-1.4.3.

Replying to claudep:

I also think that we should fallback to the language code stripped from the country code in this case.

So in this case we should check for 'en' entry in django.conf.locale.LANG_INFO? If yes, I can provide patch with tests.

I added fallback in this pull request https://github.com/django/django/pull/777

The ticket has been marked as fixed, but the patch has not been applied to the 1.5.x branch. Is there any chance this can be backported to 1.5?

comment:9 by Max Arnold, 12 years ago

I hoped it would be included into 1.5 release... Is it possible to backport this fix to 1.5.x branch for next minor release?

It looks like patch was superseded by 8c8f94fe9dcdd4983ebeb59951e6f7399bc287a2 in ticket #19763

language problem in some browsers

u"Unknown language code 'es-co'."

django = 1.5.1

comment:12 by anonymous, 11 years ago

u"Unknown language code 'en-us'."

django = 1.5.1
Works, when 'en-us' is replaced by just 'en'.

settings.py:

LANGUAGES = (
    ('en-us', ugettext('English')),
    ('uk', ugettext('Ukrainian')),
)

comment:13 by steve@…, 11 years ago

Am still getting this in 1.5.3, too:

LANGUAGES = (
    # See http://www.i18nguy.com/unicode/language-identifiers.html, but all lower case
    ('en-gb', _fake_gettext('UK English')),
    ('en-us', _fake_gettext('US English')),
)

LANGUAGE_CODE = 'en-gb'
