Hi, I've got this document:

class CourierJob
include Mongoid::Document
embeds_one :drop_address, as: :addressable, autobuild: true, class_name: "Addresses::ShipmentAddress"
end

now when i execute

(:drop_address, some address object)

on a CourierJob instance I can see the following in the rails logfile:

MOPED: 127.0.0.1:27017 UPDATE database=project_test collection=courier_jobs selector=

update={"$set"=>{"address"=>

}}

The part i am worried about is

={"$set"=>{"address"=>

because it should be

={"$set"=>{"drop_address"=>

The address model looks like this:

class Address
include Mongoid::Document
embedded_in :addressable, polymorphic: true
end

class ShipmentAddress < Address
...
end

Is there something I am doing wrong or is this a bug?

PS: if i do

.drop_address

on the same object right after the

 it gives me the correct result. After a reload from the db the the value is again the one from before 

update_attribute{{`}}
