Here's how your code should be: class Person < ActiveRecord::Base has_many :requests_as_approver, :class_name => 'Request', :foreign_key => 'approver_id' has_many :requests_as_submitter, :class_name => 'Request', :foreign_key => 'approver_id' end
class Request < ActiveRecord::Base belongs_to :approver, :class_name => "Person", :foreign_key => "approver_id" belongs_to :submitter, :class_name => "Person", :foreign_key => "submitter_id" end I can't see the need for a N:N association here (and thus as has_and_belongs_to_many association). - Maurício Linhares http://alinhavado.wordpress.com/ (pt-br) | http://blog.codevader.com/ (en) On Sat, Jan 24, 2009 at 5:03 AM, Nyc, Petr <jet.jet...@gmail.com> wrote: > Hi experts, > > I am new to rails and am struggling for several days with a following model > (Rails 2.2.2). > > People are submitting requests, each request has one submitter, one > approver, several reviewers and several responsible people. > > I was able to get this model working: > > class Person < ActiveRecord::Base > has_many :Requests > end > > class Request < ActiveRecord::Base > belongs_to :Approver, :class_name => "Person", :foreign_key => > "approver_id" > belongs_to :Submitter, :class_name => "Person", :foreign_key => > "submitter_id" > end > > > But I am really stuck in creating HABTM relationship between > requests<->reviewers and requests<->responsible_people..
