Translation outside the broswer

[Bastian]

Hi,

I understand quite well how translations and i18n work inside a browser for Django but I'm not sure about the correct way to do it outside a browser. I mean when sending a mail or a tweet. What should I use to get the language of the user that is going to receive the mail or in case of a tweet the language of the user that I will send it on behalf of. And then how do I ask Django to translate that?
I could not find it in the docs, if it exists please point me to it.

Cheers

I believe that when you detect the language you could store in the user profile the selected language (either it was automatic or manual), when sending your email just check that

You will need to have a mechanism for storing what the user's chosen
language is. Once you have that, simply do this:

from django.utils import translation

cur_language = translation.get_language()
translation.activate(get_lang_for_user(user))
# send email, tweet, etc
translation.activate(cur_language)

You would need to define the 'get_lang_for_user' function.

Thanks Tom, the logic seems pretty clear. I just didn't know about translation.activate. What does it do exactly? Change the current language? Anyway I will do my homework and google it and read the code...

Cheers.

Yeah, i18n works anywhere just put _(message) to send a mail.

Ok this is all very clear now, and the docs are quite helpful too (https://docs.djangoproject.com/en/dev/topics/i18n/translation/#using-translations-outside-views-and-templates).
But now I wonder what is the best way to implement that?
I mean in my case I use Django to automatically discover the user's preferred language according to the browser preferences and if it fails there is also a button to choose the language. I can link that button to a field in the user profile model to remember what language they set for later use with translation.activate. But in case Django displays the right language for the user automatically that field will remain empty and that would be pretty counter intuitive for the user to set their preferred language with a button when it is already displayed correctly. What would be the right thing to do in that case? Is there a way to retrieve the latest language used in the user session? Or something similar? Thanks!

You can pass the latest language_code  in the url and set that to the session
