has_many :through Mongodb (Mongoid)

Mongoid gem does not provide the has_many :through association. It's right because as a No SQL database MongoDB does not support these things. But sometimes required these association by building custom methods. So I had wrapped methods into this gems.

Add this line to your application's Gemfile:

gem 'has_many_through_mongodb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install has_many_through_mongodb

has_many :through association functionality can be achievable by using define_through method into desired model.

i.e.

class Developer
  include Mongoid::Document
  include Mongoid::Timestamps
  ...
  has_many :developer_skills, dependent: :destroy
  define_through(RateCard: :DeveloperSkill, Skill: :DeveloperSkill)
  ...
end

This will make available below methods into implemented model.

RateCard: :DeveloperSkill will create below methods has_rate_cards?, has_rate_card_ids?, rate_cards?, rate_cards

Skill: :DeveloperSkill will create below methods has_skills?, has_skill_ids?, skills?, skills
