[Aiml-programr-developers] Tests and Architecture

The to_yaml method is part of the standard library YAML module
(http://www.ruby-doc.org/stdlib/libdoc/yaml/rdoc/index.html).

Why is not working on my PC but not on yours?
I think that the explanation can be one of the following:
1 - ruby version (1.8.4)
2 - I have all the rails library in the path

One thing you might want to try is to include explicitely the YAML module:

class Response
  include YAML
  attr_reader :body, :session_id
  def initialize(body, session_id)
    @body, @session_id = body, session_id
  end
end

and if this giver problems, to require the lib:
require 'yaml'
class Response
...


I hope this will do...

Ciao,
Mauro
