In my case Alexei, this wouldn't work as I use the Middleware to operate
language changes - settings.LANGUAGE_CODE would remain defaulted to en_US
(the only lang code that I have assigned in settings.py). Instead, I have
worked around this issue by replacing settings.LANGUAGE_CODE with
translation.get_language().
