 value. The language with the highest preference that is in the django base

+Since the middlware discovers the language based on the request, your app
+might need to know what language is selected (if only to show the flag of
+that language). The selected language is stored by the middleware in the
+request as the LANGUAGE_CODE attribute. So with static translation (when
