      The to_json method does not include the _type attribute in the output. Take the following models: 

      class Pet
  include Mongoid::Document
  field :name, type: String
end

class Dog < Pet
  field :breed, type: String
  field :average_weight, type: Integer
end

class Cat < Pet
  field :minion_strength, type: Integer
end

Dog.create!
Cat.create!
puts Pet.all.to_json
# does not include _type

      This ticket should investigate why this is and if it is intentional.
