Hi, At what point in rails are the methods for a models attributes defined? Because I have the following code: http://pastie.caboo.se/140435 And it returns in irb:>> s = Playlist.find(:first).songs >> false >> 1If I do this in irb: (The PlaylistItem model has an attribute ''position''>> s = Playlist.find(:first).playlist_items[0].methods(true).include?(''position'') >> trueHow''s that possible? Does irb do some fancy trick to retrieve all methods? Must I do something in the instance_eval to make the methods appear? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Why do you care about whether the methods exists rather than just going ahead and calling them ?

Because the actual script is something like:
association_through_item.methods(true).each do |method|
#No method position here!
association_through_item.send(association_method).meta_eval do
define_method method do
association_through_item.send(method)
end
end
end
So position never gets called because it''s not in methods()
