Given two classes:

class User
  include Mongoid::Document
  has_many :tasks, dependent: :destroy
end

class Task
  include Mongoid::Document
  belongs_to :user
end

Is it possible for an instance of User to auto include itself on each of it's tasks?

user.tasks.map { |t| t.user }

The above example will cause n+1 queries, where n is the number of tasks. Is it possible to just automatically assign user to each task so it doesn't have to do a new lookup each time?
