Here's a good place to start reading: http://guides.rubyonrails.org/association_basics.html Some other notes: - 'Transaction' is not going to work as a model name; ActiveRecord uses that name internally, and redefining it may cause extremely peculiar malfunctions. - if messages are paired strictly one-to-one with replies, it may make more sense to omit the intermediate model entirely and just define a has_one/belongs_to pair. --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
