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 ?
