Rails - Aug 2009 - Best Practicies: Combining Polymorphic Results?

Hi,

I am trying to combine results on two related associations and was
wondering if there were a best practicies way to do this.

I basically have VendorCodes that are matched to both Vendors and
VendorStaff.

vendors have VendorCodes (polymorphic)
vendorStaffs have VendoorCodes  (polymorphic)

I want to easily be able to derive something like:
all_vendor_codes = vendor.vendor_codes +
vendor.vendor_staffs.collect.vendor_code

I have some models set up as, is there a better way to drive this other
than the way I''ve done it?  Thanks for any help!

My Model:

   class Vendor < ActiveRecord::Base
     has_many :vendor_staffs
     has_many :vendor_codes, :as => :vendor_codable
   end

   class VendorStaff < ActiveRecord::Base
     belongs_to :vendors
     has_many :vendor_codes, :as => :vendor_codable
   end

   class VendorCode < ActiveRecord::Base
     belongs_to :vendor_codable, :polymorphic => true
   end

Is there any reason that you can''t just do VendorCode.all ?
