Isn't this a bit risky? After all, Card the class of n derives from ActiveRecord::Base, i.e. a class, which I can't control. Now imagine that in a new version of Rails, this class would receive a to_int method (for example, to implicitly convert a model object into the id of the object). This would break my code.
