Memorize:
Allows Rails applications to do and control cache of actions.
With Memorize, you can expires your actions, calling a method in your model (or a CustomClass).
if you’ve suffered with Rails caches_action and is tired of trying to expire your cache, Memorize is for you !
See below my ‘code-explanation’:
class Article < ActiveRecord::Base
extend Memorize::Keys
[...]
end
class TestController < ApplicationController
#'classic' case of index, with categories, pagination and format support.
memorize_action :index, :key_builder => Article, :params => [:category, :page, :format]
#case of id, slug ... etc. Accessing a resource with identification.
memorize_action :show, :key_builder => Article, :key_param => :slug, :params => [:page, :format]
#case of 'custom' key, if you want to use a 'home made' solution. (here Memorize don't know how expires)
memorize_action :custom, :cache_path => lambda { |controller| "my_key" }
[...]
end
class ArticleSweeper < ActionController::Caching::Sweeper
observe Article
def after_save(article)
Article.cache_expires(:index)
Article.cache_expires(:show, :key => article.slug)
Rails.cache.delete("my_key") #Memorize does not handle custom keys
end
end
More
Memorize is designed to be simple and objetive.
Used and tested for Rails 2.3.x

sudo gem install memorizeAnd add to your environment.
Important: you can configure Memorize cache_store, adding a memorize.rb to your config/initializers. Example:
#Some examples to set Memorize cache_store:
Memorize.cache_store = Rails.cache
#Memorize.cache_store = ActiveSupport::Cache.lookup_store(:memory_store)
#Memorize.cache_store = ActiveSupport::Cache.lookup_store(:mem_cache_store, '127.0.0.1:11211')
#Your models can be 'Keys factories'
#ActiveRecord::Base.extend Memorize::Keys
