I'm stuck on this challenge.
Update the Car and Truck model classes so that each is treated as a "vehicle" which has_many Part instances.
class Car, Parts < ApplicationRecord # YOUR CODE HERE has_many :vehicle_id has_many :vehicle_type end
We couldn't find any association from the Car class to the Part class. <---- This is the error I got from the above code.
class Car < ApplicationRecord
# YOUR CODE HERE
has_many :vehicle_id
has_many :vehicle_type
end
class Truck < ApplicationRecord
# YOUR CODE HERE
end

class Car < ApplicationRecord has_many :parts, :as=> :vehicle end
class Truck < ApplicationRecord has_many :parts, :as=> :vehicle end

class Car < ApplicationRecord
has_many :parts, as: :vehicle
end
class Truck < ApplicationRecord
has_many :parts, as: :vehicle
end
