Sorted Relations
In Mongoid, the HM & HABTM relations return docs in random order. This workaround provides an ability to retrieve related documents in the same order it was stored.
Usage example:
class Post
include Mongoid::Document
include Ants::SortedRelations
field :title
has_and_belongs_to_many :authors
sorted_relations_for :authors
end
post = Post.new title: 'RESTful actions with Mongosteen'
post. = [ Author.create(name: "Oleksandr Kravets").id,
Author.create(name: "Roman Brazhnyk" ).id,
Author.create(name: "Maxim Melnyk" ).id ]
post..map(&:name)
#=> ['Alexander Kravets', 'Roman Brazhnyk', 'Maxim Melnyk']
