In my settings.py file I have:

LANGUAGE_CODE = 'ru-RU'

also, I have installed and working django-admin-tools. But admin language still english. What I'm doing wrong?

PS.

$ cat settings.py | grep USE | grep -v USER
USE_I18N = True
USE_L10N = True
USE_TZ = True

You need to set the language specifically for the admin app. Since django does not provide a language drop down as part of the default login, you have a few options:

1. Login to your normal (non admin view), with superuser/staff credentials and the correct language, then shift over to the admin URL.

2. Update the admin templates and add a language dropdown see this snippet.

3. Create some custom middleware to set the language for admin:

   from django.conf import settings
   from django.utils import translationclass AdminLocaleMiddleware:def process_request(self, request):if request.path.startswith('/admin'):request.LANG = getattr(settings, 'ADMIN_LANGUAGE_CODE',settings.LANGUAGE_CODE)translation.activate(request.LANG)request.LANGUAGE_CODE = request.LANG
   

   Add it to your MIDDLEWARE_CLASSES

   MIDDLEWARE_CLASSES = {# ...'foo.bar.AdminLocaleMiddleware',# ...
   }
   

   Set the language you want for the admin in settings.py:

   ADMIN_LANGUAGE_CODE = 'ru-RU'
