Adding a folder to your root Django application site url

If you want to have your Django app in a domain folder like this https://mydomain.com/myfoldername

Here you have the code to place in urls.py file :

from django.conf import settings
from django.urls.resolvers import LocalePrefixPattern
from django.utils.translation import get_language

from django.views.generic.base import RedirectView
APPLICATION_PREFIX = "myfoldername"


def new_language_prefix(self):
    language_code = get_language() or settings.LANGUAGE_CODE
    return '%s/%s/' % (APPLICATION_PREFIX, language_code)


LocalePrefixPattern.language_prefix = property(new_language_prefix)


trans_real.language_code_prefix_re = re.compile(r'^/myfoldername/(\w+([@-]\w+)?)(/|$)')
