Learn to Make an API-Backed Model with
summary
Shows how a Rails model can be backed by an external API rather than a database, using ActiveModel::Attributes (Rails 5.2) for typed coercion, the square_connect Ruby SDK to call Square’s Customers API, and standard Rails bits like Pagy for pagination. One include (ActiveModel::Model) brings in five convenience modules; adding ActiveModel::Dirty requires just two method hooks to get change tracking. A Customer model plus controllers and views are implemented and demoed performing fetch, create, update, delete and pagination successfully.
