DESCRIPTION:

Serialize out of the Cerealize Box - a drop-in replacement for ActiveRecord's serialize

It can auto transcode old encoding (yaml if you're using AR's serialize),
to new encoding (marshal, json, you name it) without any migration.

Current supported encoding:
1. YAML
2. Marshal
3. JSON (planned)

SYNOPSIS:

require 'cerealize'
class User < ActiveRecord::Base
  include Cerealize
  # when force_encoding set to false (this is default), cerealize is
  # smart enough to transcode old encoding (e.g. yaml) to new encoding
  # (i.e. marshal)
  cerealize :data, Hash, :encoding => :marshal, :force_encoding => false

  # and this could create accessors for values store in the hash
  attr_hash :data, [:name, :mail]

  # which makes below two equivalent:

  # user.name = 'ham'

  # which is equivalent to:

  # user.data ||= {}
  # user.data[:name] = 'ham'
end

REQUIREMENTS:

  • ActiveRecord 2 or 3

  • Tested with MRI (official ruby) 1.9.2, 1.8.7, and trunk

  • Tested with Rubinius (rbx) 1.2.3

  • Tested with JRuby 1.6.2

> gem install cerealize
# or if you want rails plugin and bleeding edge
