I am aware of how i18n/l10n is usually done in Rails3, and I chose to have a single ERB file that calls t(...) for localization. But for a particular part I need something special:

I need to display a string whose localization is coming from an external database.

So how can I know the current language, to call the external database with an en or ja parameter?

Something like $LANG in UNIX. Preferably accessible from view or controller.
