Multiple Ruby on Rails Model Relationship -

i trying access location details thru shipment model has origin , destination.

i access location information thru call this:

shipment.find(###).origin ->    :id => "###", :cs => "springfield, mo", :latitude => "#####", :longitude => "####"  shipment.find(###).dest ->    :id => "###", :cs => "springfield, mo", :latitude => "#####", :longitude => "####" 

i have following setup

shipment.rb:

class shipment < activerecord::base   belongs_to :user   has_many :vehicles, dependent: :destroy    validates :origin_id, :dest_id, :presence => true    attr_accessible :origin_id, :dest_id, (more attributes...) end 

location.rb

class location < activerecord::base   attr_accessible :cs, :latitude, :longitude   geocoded_by :cs   after_validation :geocode, :if => :cs_changed?   has_many :shipments, :foreign_key => :origin_id   has_many :shipments, :foreign_key => :dest_id end 

---

i think this:

has_one :origin, :class => "location", :origin_id 

or

scope :origin, -> (:origin_id) { location.find(:origin_id)} 

it can be

class shipment < activerecord::base ...    belongs_to :origin, class: 'location', foreign_key: 'origin_id'   belongs_to :dest, class: 'location', foreign_key: 'dest_id'  end 

for older rails

class shipment < activerecord::base     ...        belongs_to :origin, class_name: 'location', foreign_key: 'origin_id'       belongs_to :dest, class_name: 'location', foreign_key: 'dest_id'   end 

then origin location

shipment.find(###).origin 

then destination location

shipment.find(###).dest
