我有以下型號(venmas是舊的數據庫,所以我不能改變它):活動記錄外鍵關聯軌
models/venmas.rb
class Venmas < ActiveRecord::Base
establish_connection "turnkey"
end
models/yard.rb
class Yard < ActiveRecord::Base
end
我希望能夠做到:
Yard.first.venmas.first # to get the first record of venmas for that yard
這是院子裏的樣子:
#<Yard id: 1, name: "nyssa", created_at: "2012-08-07 16:58:02", updated_at: "2012-08-07 16:58:02">
和Venmas:
#<Venmas VENDOR_NUMBER: " ", ... , yard: "nyssa"> # there are a lot of columns in this one and they aren't important.
另外一個活動扳手我這是inflections.rb:
ActiveSupport::Inflector.inflections do |inflect|
inflect.irregular 'venmas', 'venmas'
end
我可以刪除這一點,如果它可以更容易,但我這樣做的所有遺留表,因爲我剛剛從他們讀。
我相信這可以通過分配foreign_key來完成,但我不確定將這些關聯的正確方法嗎?
請讓我知道是否有任何我缺少的東西。
