Laravel：laravel-translatable插件

I use the laravel (4.2) plugin (https://github.com/dimsav/laravel-translatable) and i was wondering if anyone knows how to dynamically adjusts "fallback locale".

I have tried this but still not work:

App::make('config')->set('translatable.fallback_locale', 'sl');

Thanks for answer!

I have found solution...

Config::set('translatable::fallback_locale', 'sl');

According to documentation here https://github.com/dimsav/laravel-translatable#documentation you can set your fallback locale in your configuration.

return [
   'use_fallback' => true,

   'fallback_locale' => 'sl',    
];
