Agile Web Development with Rails 8: (page 54)

class Order < ActiveRecord::Base

“This Order class is defined to be a subclass of the ApplicationRecord class.”

Should the class definition not read:

class Order < ApplicationRecord

as ApplicationRecord should already be defined as inheriting from ActiveRecord::Base in the file application_record.rb located in the models folder?

Marked As Solved
