Internationalization: in URL patterns in Django27.03.24

Django provides two mechanisms to internationalize URL patterns:

1.
Adding the language prefix to the root of the URL patterns to make it possible for LocaleMiddleware to detect the language to activate from the requested URL.

2.
Making URL patterns themselves translatable via the django.utils.translation.gettext_lazy() function.

Translating URL patterns

URL patterns can also be marked translatable using the gettext_lazy() function. Example:

from django.conf.urls.i18n import i18n_patterns
from django.urls import include, path
from django.utils.translation import gettext_lazy as _

from about import views as about_views
from news import views as news_views
from sitemaps.views import sitemap

urlpatterns = [
    path('sitemap.xml', sitemap, name='sitemap-xml'),
]

news_patterns = ([
    path('', news_views.index, name='index'),
    path(_('category/<slug:slug>/'), news_views.category, name='category'),
    path('<slug:slug>/', news_views.details, name='detail'),
], 'news')

urlpatterns += i18n_patterns(
    path(_('about/'), about_views.main, name='about'),
    path(_('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.urls 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/'
