I have two models that two relationships between them
class Tracking include Mongoid::Document belongs_to :origin_courier, :class_name => "Courier", foreign_key: "origin_courier_id" belongs_to :destination_courier, :class_name => "Courier", foreign_key: "destination_courier_id" end class Courier include Mongoid::Document has_many :origins, class_name: 'Tracking', foreign_key: "origin_courier_id" has_many :destinations, class_name: 'Tracking', foreign_key: "destination_courier_id" end
When I assign a courier to the origin_courier of a newly created tracking, it run fine.
1.9.3p194 :015 > t = Tracking.new => #<Tracking _id: 4fbcc2772cfb397930000003, _type: nil, created_at: nil, updated_at: nil, origin_courier_id: nil, destination_courier_id: nil> 1.9.3p194 :016 > t.origin_courier = Courier.last => #<Courier _id: 4fbcbb072cfb397657000004, _type: nil, created_at: 2012-05-23 10:25:11 UTC, updated_at: 2012-05-23 10:25:11 UTC> 1.9.3p194 :017 > t => #<Tracking _id: 4fbcc2772cfb397930000003, _type: nil, created_at: nil, updated_at: nil, origin_courier_id: BSON::ObjectId('4fbcbb072cfb397657000004'), destination_courier_id: nil> 1.9.3p194 :018 > t.save => true 1.9.3p194 :019 > t => #<Tracking _id: 4fbcc2772cfb397930000003, _type: nil, created_at: 2012-05-23 10:57:14 UTC, updated_at: 2012-05-23 10:57:14 UTC, origin_courier_id: BSON::ObjectId('4fbcbb072cfb397657000004'), destination_courier_id: nil>
But when I assign a courier to the destination_courier of a newly created tracking, it duplicates the value to origin_courier
1.9.3p194 :020 > t2 = Tracking.new => #<Tracking _id: 4fbcc3002cfb397930000004, _type: nil, created_at: nil, updated_at: nil, origin_courier_id: nil, destination_courier_id: nil> 1.9.3p194 :021 > t2.destination_courier = Courier.last => #<Courier _id: 4fbcbb072cfb397657000004, _type: nil, created_at: 2012-05-23 10:25:11 UTC, updated_at: 2012-05-23 10:25:11 UTC> 1.9.3p194 :022 > t2.save => true 1.9.3p194 :023 > t2 => #<Tracking _id: 4fbcc3002cfb397930000004, _type: nil, created_at: 2012-05-23 11:00:39 UTC, updated_at: 2012-05-23 11:00:39 UTC, origin_courier_id: BSON::ObjectId('4fbcbb072cfb397657000004'), destination_courier_id: BSON::ObjectId('4fbcbb072cfb397657000004')>
