Hey Walter, thanks for your reply. Yes I've read this part, but i've thought that it was not the best solution, probably i was worng. Today I've saw also this solution, that maybe fit my problem http://www.unixgods.org/~tilo/Rails/Rails_polymprphic_has_many_through_relationships.html
Please correct me if I'm wrong. You suggest me to do something like this? class Location < ActiveRecord::Base has_many :details has_many :bars, :through => :details has_many :discos, :through => :details end class Detail < ActiveRecord::Base belongs_to :Location belongs_to :Bar belongs_to :Disco end class Bar < ActiveRecord::Base has_many :details has_many :Location, :through => :details end class Disco < ActiveRecord::Base has_many :details has_many :Location, :through => :details end thanks, -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
