Ruby setters always ignore your explicit return and the last line as a return and return the attribute given it... as a feature, and this should be expected behavior as all Ruby setters behave this way. This means that you define :hello= and it accepts the attribute :world and you give :world the value of "foo" it will return "foo" because that was the value it was given for it's assignment and logically that is the value it should return if it returns anything at all. To return "expected answer" would be ambiguous no matter how you try to play it. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
