A quick note first - Player most likely shouldn't have a player_id column - the Rails convention is to simply call it id.
What you're looking for are some of the options to has_many: class Player < ActiveRecord::Base has_many :outgoing_hits, :class_name => 'Hit', :foreign_key => 'hitter_id' has_many :incoming_hits, :class_name => 'Hit', :foreign_key => 'hittee_id' has_many :hittees, :through => :outgoing_hits has_many :hitters, :through => :incoming_hits end class Hit < ActiveRecord::Base belongs_to :hitter, :class_name => 'Player' belongs_to :hittee, :class_name => 'Player' end Given a Player object, this is what you can do: player.outgoing_hits # => list of hits by the player player.incoming_hits # => list of hits to the player player.hittees # => list of all players hit by this player player.hitters # => list of all players hitting this player You can switch the names around, but that's the idea. --Matt Jones On Mar 27, 9:06 pm, Brad A <[email protected]> wrote: > Consider 2 tables: > Player-> column player_id > and > Hit-> columns player_id, hit_player_id > > I want one model for Player and one model for a Hit. > Any player has many hits against another player. > So from a Player I want to be able to get all the Hits, and from the > Hit get the hit Player. > On the other hand, from a Player I want to retrieve all Hits against > that player (were player_id = hits.hit_player_id) > and the player_id from that hit. > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
