Rails i18n: How to know what is the current language?

Question

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.

Answer 1

I18n.locale # Get and set the current locale

As Oshan Wisumperuma states in the comments, the local is stored in a symbol, like :en or :de (not a string 'en' or 'de') in an if statement:

if I18n.locale==:en
...
end
