Association problem in one direction

I have these models

class Game < ActiveRecord::Base
  belongs_to :home_team, :class_name => 'Team'
  belongs_to :away_team, :class_name => 'Team'
  belongs_to :field
end
class Person < ActiveRecord::Base
  has_many :affiliations
  has_many :teams, :through => :affiliations
end
class Team < ActiveRecord::Base
  has_many :affiliations
  has_many :players, :through => :affiliations, :source => :person
  has_many :games
end
class Affiliation < ActiveRecord::Base
  belongs_to :person
  belongs_to :team
end

I with the associations above, I can get the players for the teams,
the home team and away team players from the games.

I want to be able to go back and get the games that each team and/or
player plays in. The associations work in one direction but not in the
other. How do I work back through the home_team and away_team
connections and get home games, away games and the totals for a given
player or team?

Any ideas?

Thanks

Rails cannot infer how to get from Games --> Teams, from your models
rails is looking for team_id in Games

Based on your models, I can see only one way:

class Team < ActiveRecord::Base
        has_many :affiliations
        has_many :players, :through => :affiliations, :source
=> :person
        has_many :home_games, :class => 'Games', :foreign_key =>
'home_team_id'
        has_many :away_games, :class => 'Games', :foreign_key =>
'away_team_id'
end

You could then access team.away_games and team.home_games
