EX. Object.cache_find(10)

or

Object.cache_find(:all, :conditions => [‘field>?’,5])

If you want to use an active record shortcuts you can:

Object.cache_find_first(params) Object.cache_find_last(params) Object.cache_find_all(params)

EX.

Object.cache_find_first Object.cache_find_last Object.cache_find_all(:conditions => [‘filed>?’, 5])

Cache reset

If you want to reset cache after predetermined amount of time you can specify time in database.yml config file through cache_expire directive:

cache_expire: 30.seconds cache_expire: 2.hours cache_expire: 1.day cache_expire: 1.month

If you want to force the expire the cache manually you can call the method

cache_reset(id, params=nil)

or shortcuts

cache_reset_first(params=nil) cache_reset_last(params=nil) cache_reset_all(params=nil)
