MongoID has_any_belongs_to_many Reference

I have two models

Developer

  has_and_belongs_to_many :founding_organizations, class_name: 'Organization'
  has_and_belongs_to_many :collaborating_organizations, class_name: 'Organization'

Organization

  has_and_belongs_to_many :founders, class_name: 'Developer'
  has_and_belongs_to_many :collaborators, class_name: 'Developer'

How can I make the Developer model code work without changing anything on the organization model. Right now when you create an organization and use organization.founders << current_developer everything works fine and the developers id is stored in a founders array on the organization but if you query current_developer.founding_organizations the response is empty, how can I achieve this workflow? I had this working in ActiveRecord with joining tables but I moved to MongoDB which has so far been 10x better, its just getting used to doing things differently that has me confused.

Not sure if this is possible without changing Organization model. How about using inverse_of option?

 has_and_belongs_to_many :founding_organizations, class_name: 'Organization', inverse_of: :founders
 has_and_belongs_to_many :collaborating_organizations, class_name: 'Organization', inverse_of: :collaborators

 has_and_belongs_to_many :founders, class_name: 'Developer', inverse_of: :founding_organizations
 has_and_belongs_to_many :collaborators, class_name: 'Developer', inverse_of: :collaborating_organizations

You'll find more info here http://mongoid.org/en/mongoid/docs/relations.html#common
