API Problem

Im using the API for rails with name: ruby_15-06-2012 from kaltura. Im trying to list the flavor transcoding through the flavor asset service. I created a session with a global client and i used the next code to get the information that i want.

@@client.flavor_asset_service.get_by_entry_id('0_lb65nbn6')

I put the kaltura_client.rb and the kaltura_client_base.rb on the lib folder of rails application. I included the file in a initializer file where i created the client and the session.

The results is:

1.9.2p290 :001 > @@client.flavor_asset_service.get_by_entry_id('0_lb65nbn6')
