Spree Decorators

Commands use the Spree CLI (spree …). On a classic Rails app without the CLI, use bin/rails g … from the app root. Paths assume the Rails app lives in server/.

Decorators change existing Spree classes from your app with Ruby's Module#prepend, using a Spree filename convention and two generators. They couple you to Spree internals — use them for structural changes (association, validation, scope, read-only helper method, a narrowed controller scope), not for behavior.
