Let’s say I have a collection of Address ActiveRecord instances - and
let’s say that each Address has the property “zip”. What’s the best
rails/ruby idiom for retrieving a collection of these zips?
Of course I can just iterate over my Addresses and pull out the zip but,
as OCD as it sounds, I’m convinced that there’s something in the API
that’ll let me say “collection.eachProperty(‘zip’)” or something along
Thanks for any help you can provide,
