When I read the David Kahn's response, I thought it strange to have
controller code in the model and was going to query him on it so I'm glad
that others think the same.
As for Nick's response, I will look into it_behaves_like (I remember seeing
that in the book with a pizza example) It sounds good to me.
Thanks for the replies.
