ActiveRecord::Errors#to_xml

Here’s a method that will allow you to call to_xml on an ActiveRecord::Errors object. We’re using this to pass errors between web apps via a web service api.



class ActiveRecord::Errors

  def to_xml(options = {})

    options[:indent] ||= 2

    options.reverse_merge!({ :builder =>

      Builder::XmlMarkup.new(:indent =>

        options[:indent]), :root => "errors" })

    options[:builder].instruct! unless options.delete(:skip_instruct)



    options[:builder].__send__(options[:root].to_s.dasherize) do |xml|

      @errors.each do |key, value|

        xml.__send__(key.to_s.dasherize) do |xm|

          for message in value

            xm.message(message)

          end

        end

      end

    end



  end

end
