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).
