Serialization improvements for CouchRest Model

serialization.rb

module CouchRest
  module Serialization
    extend ActiveSupport::Concern
    include ActiveModel::Serialization
    include ActiveModel::Serializers::JSON
    include ActiveModel::Serializers::Xml

    included do
      class_attribute :include_root_in_json
      self.include_root_in_json = false
    end

    def serializable_hash(options = nil) 
      options ||= {}
      options[:except] ||= []
      options[:except].push :_id
      options[:methods] ||= []
      options[:methods].push :id
      options[:except] ||= []
      options[:except].push :chapters
      super(options)
    end

    def to_json
      hash = as_json
      hash.to_json
    end
  end
end

Added the include_root_in_json = false setting because Rails has a retarded default to true. Who includes the root in json???
