      Given the models

      class Family
  include Mongoid::Document

  embeds_many :children
end

class Child
  include Mongoid::Document

  embedded_in :family

  belongs_to :school
end

class School
  include Mongoid::Document
end

      I assumed it would be possible to eagerly load the schools of all children in all families, but it threw an exception:

      2.5.8 :004 > Family.all.includes(children: :school).each { |f| p f }
Traceback (most recent call last):

NoMethodError (undefined method `eager_loader' for Mongoid::Association::Embedded::EmbedsMany::Proxy:Class)
