set language within a django view

Question

background: The view is called when a payment service pings back a payment outcome behind the scenes - afterwhich I need to send an email in the right langu

Answer 1

If just want to get the translated strings for a language for whatever reason, you can use override as a decorator like this:

from django.utils import translation
from django.utils.translation import ugettext as _

with translation.override(language):
    welcome = _('welcome')

Answer 2

If you are using django 1.10 or higher, there's a new syntax for custom middleware:

from django.utils import translation

class LocaleMiddleware(object):

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):

        language_code = 'en' #TODO, your logic

        translation.activate(language_code)

        response = self.get_response(request)

        translation.deactivate()

        return response
