[FIXED] Django: How to dynamically change urlpatterns based on the hostname

Issue

In Django it is possible to change the urlpatterns dynamically.

For example the i18n module is doing this. https://docs.djangoproject.com/en/5.0/topics/i18n/translation/#translating-url-patterns

I want something similar which is changing the pattern depending on the hostname for a view.

for exmaple for www.example.com I want:
path("articles/", views.articles),

www.example.it
path("articolo/", views.articles),

www.example.de
path("artikel/", views.articles),

There should be a lookup table for each hostname and a default value if it is not defined.

How could I do this without creating a new urls.py for each hostname?

Solution

We can use the method lazy to use methods as an url pattern:

Here is an example:

from django.conf.urls import url
from django.utils.translation import get_language
from django.utils.functional import lazy
from django.urls import path

url_citylist = {
    'de': 'staedteliste',
    'pl': 'lista-miast',
    'en': 'citylist',
    ...
}

def get_pattern():
    current_language = get_language()
    if current_language in url_citylist:
        pattern = url_citylist[current_language]
    else:
        pattern = url_citylist['de']
    return pattern

def city_list_url():
    return r'^' + get_pattern() + '/$'


lazy_city_list_url = lazy(city_list_url, str)

urlpatterns = [
    url(lazy_city_list_url(), views.CityListView.as_view(), name='city_list'),
]
