How to implement mongoid many-to-many associations?

Question

I want to port a social network to Mongoid. The join table between friends is very large. Is there any way for Mongoid to handle this join table out of the box? I've seen a couple of in-model roll-your-own solutions to it, but nothing the looks efficient. Is there a way to handle this? Or is this a case where I shouldn't be using Mongoid?

Answer 1

this method is deprecated. you can now use references_and_referenced_in_many like so:

class Person
  include Mongoid::Document
  field :name
  references_and referenced_in_many :preferences
end

class Preference
  include Mongoid::Document
  field :name
  references_and referenced_in_many :people
end
