Examples

@articles = cache(‘articles’) do

Articles.latest

end

Or:

@articles = cache([‘articles’, user.id], :expires_in => 15.minutes)

# Advanced Rails Recipies says: "expires_in option works only with memcached store"
Articles.latest

end

Also if you’d like to have short ‘cache’ call in your model you can have it - add the following method to the model:

def cache(key, options = {})

ActionController::Base.cache_store.fetch(key, options) { yield }

end

cache
