With association extensions, like user.items.tagged("foo"), how do I access the "user" object from within the extension method? The code would be e.g. class User < ActiveRecord::Base has_and_belongs_to_many :items do def tagged(tag) return "These are items tagged %s from user %s." % [tag, ???] end end but how would I get a hold of the user in question, within that method? Since "self" in the method refers to the "items" collection, I can do self.user, but that seems very much like a hack, and will obviously not work if the items collection is empty.
