WillCache provides simple API for caching ActiveRecord objects that uses ActiveSupport Cache Store internally so that it's trivial to switch cache storage. WillCache API is heavily inspired by excellent but no longer maintained cache_fu plugin and one of the goals of the gem is to provide drop-in replacement for it.

Example usage

>> User.last.cached(:profile)
  User Load (0.000581) (1 Row)   SELECT * FROM `users` ORDER BY users.id DESC LIMIT 1
  Cache miss: User:65:profile
  Profile Load (0.000454) (1 Row)   SELECT * FROM `profiles` WHERE (`profiles`.user_id = 65) LIMIT 1
  Cache write (will save 1.64ms): User:65:profile
=> #<Profile id: 65, first_name: nil, last_name: nil, ...>

Example shows inline log in Rails console.
