class Account < ActiveRecord::Base # Catch-all for methods like is_admin_or_operator. def method_missing(method_name, *arguments) return super unless method_name.to_s =~ /\Ais_/ subclasses_for_scan Regexp.union(*Object.subclasses_of(Account).map { |c| c.name.downcase }) klasses = method_name.to_s.scan(subclasses_for_scan) klasses.include?(self.class.to_s.downcase) end hello. I''m trying to use the above code but I have a problem with subclasses_of, returning random results, probably because of model load order. is there a stable way to fetch every subclass of Account without including every subclass in the same file or by parsing model source files? also I would like to move subclasses_for_scan implementation outside this method, to make only one call. thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
