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 => 6
