internationalization - django - understanding LocaleMiddleWare (translation.deactivate) -

-

i use django.middleware.locale.localemiddleware website i18n'ed , make language 'switcher' via set_language redirect.

and can not understand couple of things:

  1. why call translation.deactivate (source on github) during process_responce?

  2. does mean can not using middleware? (it shows page in different language once, , switches back.)

translation.deactivate called because current language stored in global (thread local) variable. set when request comes in, , must un-set when request finished prevent "leaking" next request (ex, imagine thread handles request must localized portuguese, request no localization set. if portuguese localization wasn't deactivated, next request localized portuguese).
