      We have the following models relation in our project:

       

      class A
  include Mongoid::Document

  embeds_many :locations
end

class Location
  include Mongoid::Document

  embeds_many :buildings
end

class Building
  include Mongoid::Document
end

location = Location.create!
location.buildings << Building.create!

a = A.create!
a.locations << location
a.dup

       

      So when we call dup on top level class A object the error above is raised
