#touch, :touch, and #cache_key

Reported by Xavier Noria | September 17th, 2010 @ 07:51 PM | in The Rails 3 Way

Section 5.4.14 explains #touch and :touch. Don't have enough context to see whether this is a good point in the book to say this, but :touch is mostly there for cache autoexpiration, with their cousin #cache_key.

Perhaps just a sentence saying ":touch is notably useful for cache autoexpiration, see such and such later".
