如何在Rails中缓存模型对象? [英] How can I cache Model objects in Rails?

问题描述

有没有一种我可以在Rails中使用的技术，以便每当对Model对象执行简单的查找"时，都会首先搜索memcached的结果，只有在没有找到结果的情况下，才会对数据库?

Is there a technique that I can use in Rails so that whenever a simple "find" is performed on a Model object, memcached is first searched for the result, only if no result is found will a query by then made to the database?

理想情况下，我希望解决方案是隐式的，这样我就可以编写Model.find(id)，它首先检查缓存，如果需要数据库查询，则需要将返回的对象添加到缓存中即我不需要用其他代码包装Model.find(id)来检查缓存中是否有匹配的内容.

Ideally, I'd like the solution to be implicit, so that I can just write Model.find(id), it first checks the cache and if a database query is required that the object returned is then added to the cache i.e. I don't need to wrap the Model.find(id) with additional code to check the cache for matching contents.

谢谢！
