serialized_attr_accessor.rb

module SerializedAttrAccessor
  
  module ClassMethods
    
    def define_serialized_attr_accessor(attribute)
      self.class_eval %Q{
        def #{attribute}=(val)
          self.serialized_column[:#{attribute}] = val
        end
        
        def #{attribute}
          self.serialized_column[:#{attribute}] 
        end
      }
    end
    
    def serialized_attr_accessors(*attributes)
      serialize :serialized_column, Hash
      
      attributes.each do |attribute|
        define_serialized_attr_accessor(attribute)
      end
    end
    
  end
  
  def serialized_column
    super || Hash.new
  end
  
  def self.included(base)
    base.extend ClassMethods
  end
