Cache for ActiveRecord objects, backed by ActiveSupport::CacheStore of your choice.

Example

create table users (

`id` int(11) not null increment,
`first` varchar(255),
`last` varchar(255),
`email` varchar(255),
`age` int(11),
`points` int(11),
primary key (`id`),
unique key `index_users_on_email` (`email`),
unique key `index_users_on_last_first` (`last`, `first`)

);

class User < ActiveRecord::Base

cache_it do |c|
  c.index :last, :first
  c.index :email
  c.counters :points
end

end

user = User.cache_it.find :first => “Joe”, :last => “Schmoe” user.email = “[email protected]” user.points = 5 user.age = 29 user.save user.age = 30 user.cache_it.write

User.cache_it.read(:email => “[email protected]”).first.age

> 30

User.where(:email => “[email protected]”).first.age

> 29

user.save

> true

User.where(:email => “[email protected]”).first.age

> 30

user.cache_it.increment :points

> 6

User.cache_it.read(:first => “Joe”, :last => “Schmoe”).points

> 6

User.where(:first => “Joe”, :last => “Schmoe”).first.points

> 5

user.save

> true

User.where(:first => “Joe”, :last => “Schmoe”).first.points
