Agile Web Development with Rails 7: ApplicationRecord should be AR::Base (Page 41)
The example at the bottom of page 41 illustrates stand-alone usage of Active Record. It requires active_record, and It omits stuff related to the connection for convenience. Cool.
The superclass should be ActiveRecord::Base. That is your regular superclass in stand-alone usage (as it was in Rails for many years). ApplicationRecord is a class generated by Rails in app/models.
