Django URL internationalization

This Django app makes it possible to prefix URL patterns with the active language and to make URL patterns translatable by using gettext. As well this package contains a middleware which is able to activate the right language (based on the language-prefix in the requested URL).

Translating URL patterns

After installing this package, URL patterns can also be marked translatable using the ugettext_lazy() function. Example:

from django.conf.urls.defaults import patterns, include, url
from django.utils.translation import ugettext_lazy as _
from i18nurls.i18n import i18n_patterns

urlpatterns = patterns(''
    url(r'^sitemap\.xml$', 'sitemap.view', name='sitemap_xml'),
)

news_patterns = patterns(''
    url(r'^$', 'news.views.index', name='index'),
    url(_(r'^category/(?P<slug>[\w-]+)/$'), 'news.views.category', name='category'),
    url(r'^(?P<slug>[\w-]+)/$', 'news.views.details', name='detail'),
)

urlpatterns += i18n_patterns('',
    url(_(r'^about/$'), 'about.view', name='about'),
    url(_(r'^news/$'), include(news_patterns, namespace='news')),
)

After you've created the translations, the reverse() function will return the URL in the active language. Example:

from django.core.urlresolvers import reverse
from django.utils.translation import activate

>>> activate('en')
>>> reverse('news:category', kwargs={'slug': 'recent'})
'/en/news/category/recent/'

>>> activate('nl')
>>> reverse('news:category', kwargs={'slug': 'recent'})
'/nl/nieuws/categorie/recent/'

Reversing in templates

If localized URLs get reversed in templates they always use the current language. To link to a URL in another language use the language template tag. It enables the given language in the enclosed template section:

{% load i18nurls i18n %}

{% get_available_languages as languages %}

{% trans "View this category in:" %}
    {% for lang_code, lang_name in languages %}
        {% language lang_code %}
            <a href="{% url category slug=category.slug %}">{{ lang_name }}</a>
        {% endlanguage %}
{% endfor %}
