Belongs_to太多列ID

Question

我想創建一個匹配表。此匹配表將查找從團隊表中獲取其信息。我無法讓協會工作。

class Match < ActiveRecord::Base 
#  
end 

class Team < ActiveRecord::Base 

belongs_to :matches, :class_name => "Match", :foreign_key => "hometeam_id"  
belongs_to :matches, :class_name => "Match", :foreign_key => "awayteam_id" 

end 

我配對錶有

# id 
# hometeam_id 
# awayteam_id 
# … 

我的團隊表有

# id 
# name 
# … 

我希望能夠做到以下幾點

game = Match.find(:first) 
# <Match id: 1, hometeam_id: 64810937, awayteam_id: 78380562, 
game.hometeam 
# returns "Toronto" 

我不太確定我的belongs_to是否正確。我覺得我正在重複自己，他們可能是一個更好的方法。思考？

UPDATE解決

class Match < ActiveRecord::Base 

belongs_to :hometeam, :class_name => "Team" 
belongs_to :awayteam, :class_name => "Team" 

end 


class Team < ActiveRecord::Base 

    has_many :homegames, :class_name => "Match", :foreign_key => "hometeam_id" 
    has_many :awaygames, :class_name => "Match", :foreign_key => "awayteam_id" 

end 

離開這件事對誰比誰運行到類似的問題。

試試這個：

class Team < ActiveRecord::Base 

belongs_to :hometeam, :class_name => "Match", :foreign_key => "hometeam_id"  
belongs_to :awayteam, :class_name => "Match", :foreign_key => "awayteam_id" 

end
