I have a few strings in the backend I'd need to occasionally translate to other language before using them. I plan to save the user language selection into the database so it would be easy to get it from there. But, what is unclear for me, is if I implement localization and have a couple of different language files, how can I use the right language version? I can't read the language selection from cookies, url, user session etc. Can I use the language code from my database to choose which translation I'll use?

CodePudding user response：

You can manually activate the language with activate. Here's an example, given the user has an language attribute with a valid language code:

from django.utils.translation import activate, deactivate
from django.utils.translation import gettext as _

user = MyUserModel.objects.get(username=username)
activate(user.language)
my_string_translated_into_users_language = _("Hello")
deactivate()

That way, you override the current session language. Then deactivate() will deactivate the currently active translation object so that further _ calls will resolve against the default translation object, again.
