Hi! My problem instance's properties failed to share among the actions. e.g. In action 'collect', I created an "CD" instance with some "Album"s as its properties using one-many relationship provided by rails API. Before saving to the db, I just pass the 'CD' instance to action 'show', using @instance_var. But I can't get properties information using 'cd.albums', it alway return an empty array.
The reason why the objects do not get persisted is that modification of objects is necessary. Why can't I navigate through the relation and How can I pass around the instance without? -------------------------------------------------------------------- # model class Cd < ActiveRecord::Base has_many :albums end class Album < ActiveRecord::Base belongs_to :cd end # in action "collect" @cd = Cd.new Dir.chdir("/media/cdrom") Dir.foreach(Dir.pwd) do | dir | logger.debug "found directory : [#{dir}]" if dir != "." && dir != ".." # collect album inf raw_info = dir @al = Album.new @al.name = dir.to_s @al.cd = @cd logger.debug "Checking album...@al.name}]'s belonging [...@al.cd.volumn_name}]" logger.debug "Find album folder [#{dir}], thus cd contains [...@cd.albums}]" end end end logging: Processing MusicInventoryController#collect (for 127.0.0.1 at 2009-01-08 14:13:14) [GET] found directory : [.] found directory : [..] found directory : [20090101] Checking album[20090101]'s belonging [test] Find album folder [20090101], thus cd contains [] Rendering music_inventory/show --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
