我有2種型號:如何在Rails 3中創建複雜的有很多關係?
Location
+ id
+ woeid
TownKeyTowns
+ id
+ town_woeid
+ key_town_woeid
而且關係是這樣:
1地點有1個key_town_woeid,這是通過town_woeid訪問。
town_woeid和key_town_woeid都是直接使用位置表中的woeid列的位置。
我想可以說,例如:
Location.key_town
到目前爲止,我有以下幾點:
town_city = TownKeyTown.where(:town_woeid => Location.woeid).first
key_city = Location.find(town_city.key_town_woeid)
幫助!
謝謝!
