L10N localization of numbers in templates using Jinja2 and Django

I'm trying to get Jinja2 (and Django, via django-jinja) to localize a number, eg. 123456 becomes 123,456 (or, of course, 123.456 depending on the locale). I've read every bit of documentation I can find on the subject, and can't find anything that actually works. Using standard DTL, one could just do:

{% localize on %}{{ some_number }}{% endlocalize %}

This works fine in my project using regular Django templates, but of course, doesn't work in Jinja2. I mention that this works fine because anything involving settings.py such as USE_L10N being False can be ruled out.

I've tried the following, all based on documentation I've found:

So, how can I easily and properly localize a number using Jinja2?

Though it is an old question, I encountered the same found this solution feasible without lot of edits. Here is library that implements L10n for jinja2 templates. You could integrate it with your application like 

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.jinja2.Jinja2',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'extensions': [
                'jdj_tags.extensions.DjangoStatic',
                'jdj_tags.extensions.DjangoI18n',
                'jdj_tags.extensions.DjangoL10n',
            ]
        },
    },
}

Figured it out. Jinja2 doesn't seem to handle localization on its own, but django-jinja includes a built-in contrib that wraps django.contrib.humanize.templatetags. According to the documentation for that, format localization is respected using the |intcomma filter if L10n is enabled.

To use it, add django_jinja.contrib._humanize to INSTALLED_APPS in settings.py:

INSTALLED_APPS += ('django_jinja.contrib._humanize',)

And then in templates, simply use the |intcomma filter:

{{ some_number|intcomma }}
