Ruby on Raisl Multi Database Connect

2006年12月14日星期四

今天看到 Rails可以有两个以上的数据库吗 以及 Multiple database handling with Rails。他們的作法有點詭異,而且有一個關鍵性的問題,每次 request 每個不相關的頁面也都得連接一次 external database。可是 Rails 要做這件事情應該沒那麼複雜呀?


1. 設定 config



extradb_production:

adapter:     mysql

host:        localhos

username:    root

password:    blabla

database:    extradb_prod


2. 在相關 Model 利用 estabilish_connection 去做連接而外設定


class lala < ActiveRecord::Base
establish_connection :extradb_production
end


然後收工,連跨 DB 的關連性都沒問題。
