如何搭配的MongoDB和传统的DB在Rails的？ [英] How to mix mongodb and a traditional db in Rails?

问题描述

我正在考虑使用的MongoDB（蒙戈映射器）为我的Rails应用程序的一部分。我不准备去整猪的MongoDB，因为有依赖于传统的DB太多有用的宝石。

I am considering using MongoDB (mongo-mapper) for a portion of my rails application. I am not ready to go whole hog MongoDB because there are too many useful gems that depend on a traditional DB.

话虽这么说有我的应用程序的一部分，将是巨大的，充分利用文档型数据库。

That being said there are parts of my application that would be great to leverage a document database.

有没有人成功过混合这两种方法？你如何链接ActiveRecord模型与mongomapper模式？

Has anyone had success mixing the two approaches? How do you link activerecord models with mongomapper models?

推荐答案

MongoMapper没有实现加载ActiveModel，但我觉得有GitHub上几个叉的事情。你可以使用Mongoid代替（它）和Mongoid文档和ActiveRecord的条目之间的关系也只是神奇的工作。我知道很多人都这样做。

MongoMapper doesn't implement ActiveModel yet, but I think there are a few forks on github that do. You could use Mongoid instead (which does) and your relationships between Mongoid docs and ActiveRecord entries would just magically work. I know a number of people are doing that.

不过，我不想将它们混合，除非我绝对必须有一个RDBMS的某些原因。

That said, I wouldn't want to mix them unless I absolutely had to have an RDBMS for some reason.
