Mongoid:使用多个数据库? [英] Mongoid: using more than one database?

问题描述

我在Rails应用程序中使用MongoDB和MongoID，某些模型如何成为同一服务器上不同mongo数据库的一部分?我将如何完成类似的任务?我以前遇到过与mysql相同的问题，找不到合理的解决方案.

I'm using MongoDB and MongoID in a rails app, how can some models be a part of a different mongo database on the same server? How would I accomplish something like that? I've run into the same problem with mysql before and couldn't find a reasonable solution.

有什么想法吗?

推荐答案

最新版本的Mongoid支持此功能.请参见文档.

The newest versions of Mongoid support this. See the docs.

摘要:

config/mongoid.yml:

config/mongoid.yml:

defaults: &defaults
  host: localhost
  slaves:
    - host: localhost
      port: 27018
    - host: localhost
      port: 27019
  databases:
    secondary:
      database: secondary_database
      host: localhost
      port: 27020
      slaves:
        - host: localhost
          port: 27021
        - host: localhost
          port: 27022

在您的模型中:

class Business
  include Mongoid::Document
  set_database :secondary
end
