Ruby 属于\u的列ID过多

我正在尝试创建一个匹配表。这个matches表将从Teams表中获取它的信息。我很难让协会运作起来

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 

我的团队表有

# id
# hometeam_id
# awayteam_id
# …

# id
# name
# …

我希望能够做到以下几点

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

game=Match.find（：first）
#“团队”
属于：awayteam，：class\u name=>“团队”
结束
类团队“比赛”，：外键=>“家庭队id”
有很多：awaygames，：class\u name=>“Match”，：foreign\u key=>“awayteam\u id”
结束

把这个留给遇到类似问题的其他人。

试试这个：

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 

class团队“Match”，：foreign\u key=>“hometeam\u id”
属于：awayteam，：class\u name=>“Match”，：foreign\u key=>“awayteam\u id”
结束

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
