ActiveStoreAccessor

active_store_accessor makes work with store accessors more productive. There is no need to cast a serialized attribute to required type(boolean, time, float, etc). Just define it with a tiny wrapper method and everything is done for you.

Usage

Basic use case:

class Profile < ActiveRecord::Base
  # basic usage(where `info` is a store column)
  active_store_accessor :info, age: :integer, birthday: :time

  # with default values
  active_store_accessor :info, score: { type: :float, default: 0.0 },
    active: { type: :boolean, default: true }
end

profile = Profile.new
profile.age = "23"
profile.age # => 23
profile.birthday = Time.new(2014, 5, 31)
profile.birthday # => 2014-05-31 00:00:00
profile.score # => 0.0
profile.score = 4.5
profile.score # => 4.5

Extra logic in property methods:

# Story:
#  users have a rank, but if an user was locked by admins
#  nobody can change it rank & it's value should be equal to zero
class User
  active_store_accessor :info, rank: :float

  def rank
    0 if locked?
    super
  end

  def rank=(value)
    super unless locked?
  end
end
