Answer written in haste, so may well be wrong...
Rails associations are not Arrays even though they claim to be. I think
they are ActiveRecord::Associations::AssociationProxies; why they claim to
be Array I have no idea, simply being Enumerable would have sufficed I
would have imagined. Why they proxy an array rather han extending it I
have no idea. I have very few ideas :-). I personally believe proxies
that lie to the developer like this should Be Considered Harmful, but it's
not my opinion that counts in this particular piece of opinionated
I haven't yet worked out how to tell an AP from an Array.
Hope this helps. Hope I've remembered correctly too!
