Sql cache
Query caches are created at the start of an action and destroyed at the end of that action and thus persist only for the duration of the action.

Rails 2.2.2 經測試, 在action, view, helper 裡default 都已有query cache, 只有在model 沒有, 還是必須使用
query cache
<br /> def self.query_cache <br /> User.cache do <br /> User.all <br /> User.all <br /> User.all <br /> end <br /> end <br />
