controller

To create thin Rails controllers, you delegate business logic to service objects and enforce strong parameters with Pundit authorization. This approach ensures controllers handle only HTTP concerns, routing, and policy checks.

The best way to test Rails controllers with TDD is using a request-spec-first approach. You write request specs to validate RESTful routes, strong parameters, and Pundit policy enforcement before implementing the controller actions.

Yes, this Rails controller approach works with Turbo Streams by generating responses that support progressive enhancement. Controllers scaffolded this way handle Turbo Stream formats alongside standard RESTful actions.

Yes, you can use Pundit authorization for RESTful controller actions in Rails. The controller integrates Pundit policies and policy_scope to enforce permissions across index, show, new, create, edit, update, and destroy actions.

You scaffold RESTful Rails controllers by providing a resource name and desired actions. The process enforces strong parameters, robust boundary checks, and error handling while maintaining a clear separation of concerns.

You should not use thin controllers when your application lacks RESTful routes or does not separate business logic into services. Thin controllers require delegating complex operations to service objects and policy-based authorization to function effectively.
