Django-cms: ValueError: invalid token in plural form: EXPRESSION

[abduakhatov]

Trying to add a translation of a page in django cms, which is Uzbek, not supported by django CMS. I added this inside settings.py

# CMS_LANGUAGES = { 
...
, {
            'code': 'uz',
            'name': gettext('Uzbek'),
            'redirect_on_fallback': False,
            'public': True,
            'hide_untranslated': True,
        }
}

LANGUAGES = (
    ## Customize this
    ('en', gettext('en')),
    ('ru', gettext('ru')),
    ('uz', gettext('uz')), # <- this one
)

but when I access http://127.0.0.1:8000/uz/, the output is:

The current path, /ru/uz/, didn't match any of these.

So, in accordance to some googling, I decided to add my own language .po files. Then added in settigs.py:

PACKAGE_ROOT = os.path.abspath(os.path.dirname(__file__))
LOCALE_PATHS = (
    os.path.join(PACKAGE_ROOT, 'locale'),
)

EXTRA_LANG_INFO = {
    'uz': {
        'bidi': False,  # right-to-left
        'code': 'uz',
        'name': 'Uzbek',
        'name_local': 'Ozbek',  # unicode codepoints here
    },
}

# Add custom languages not provided by Django
import django.conf.locale

LANG_INFO = dict(django.conf.locale.LANG_INFO, **EXTRA_LANG_INFO)
django.conf.locale.LANG_INFO = LANG_INFO

# Languages using BiDi (right-to-left) layout
LANGUAGES_BIDI = global_settings.LANGUAGES_BIDI + ["uz"]

then in terminal:

./manage.py makemessages -l uz
./manage.py compilemessages

restarted and reload browser outputs following error:

raise ValueError('invalid token in plural form: %s' % value)
ValueError: invalid token in plural form: EXPRESSION

Could you please help to resolve my issue, any recomendation please to add Uzbek translation to my page?

Hello, @abduakhatov .

Have you tried to find an answer at StackOverflow?
I found a similar ticket at Django project.
Take a look at this commit. Maybe it is your case?

@DmytroLitvinov Thank you! it worked. I should confess that with this answer you not only resolved my headache, but also taught me the most important lesson; To be honest I overwatched all sources, but because of my unprofessionalism and un-attentiveness, I missed a key point. This does not feels so painful, as feeling that sometimes just googling is not enough!

Seek and you will find; knock and the door will be opened to you.

Have a nice working week.
