详细解读Rails Caching

2006年9月10日星期日

问题出现:


I am trying to use caches_action and the agile book says that it is keyed

off the URL, however it does not seem to pick up the URL parameters.


http://localhost:3000/controller/action/id?foo=bar

and

http://localhost:3000/controller/action/id?foo=foobar


Returns the same page.


问题原因:


Rails Caching不能Cache Parameter,所以caches_action时会出现上述原因。 


解决方法:


1. 修改rails routes.rb,将原来的”?parameters=”的调用方式更改为/action/:parameters的访问方式,以使用rails cache不同的fragment


2. 安装一个rails-caching的plugin,然后修改environment.rb中增加cache key for action : Action Cache Update Plugin
