Ahoy is a tracking library that has an automatic mode that will persist tracking data to a Mongoid Store.

The tracking seems to fail when attempting to track models with nested documents. I have the following error

> undefined method `bson_type' for #<Payment::Subscription:0x007f90a95cd5f0>

Where Payment::Subscription is a Mongoid document embedded_in a polymorphic company document

The first call to the Mongoid library is a call to an #upsert method, which after a long series of calls triggers the final error

For reference here is my embedded document

{{module Payment
class Subscription
include Mongoid::Document
include Mongoid::Timestamps
include Mongoid::Attributes::Dynamic

embedded_in :subscribable, polymorphic: true
...
end }}

And here is my trace
