I have the following models: class MainService < ActiveRecord::Base has_one :travel_service end class TravelService < ActiveRecord::Base belongs_to :main_service end I can use the following: @main_service.travel_service = TravelService.new But I can't use the following: @main_service.send("travel_service") = TravelService.new It says " unexpected '=', expecting $ " What's the correct way of using the "send" method? (I think this is mainly due to my bad ruby knowledge :( ) Thanks in advance for any help.

Actually, what I want is this: @main_service.send(service_type, TravelService.new) Where service_type may contain sevral other service types (including travel_service). All those service types belongs_to MainService (and MainService has_one of each of them). On Feb 12, 10:41 pm, Alex W. <firstname.lastname@example.org>
