I don't know if its efficient, or right, but ActiveRecode::Base#attributes [1] seems to do the job If you already know the fields, you can also do something like that : [ :firstname, :lastname, ... ].each do |attr| val = model.send attr end Hope it will help [1] : http://api.rubyonrails.org/classes/ActiveRecord/Base.html#M002047 -- Gabriel Laskar <[email protected]> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
