Can this skill help improve my application's test coverage?

Yes. By extracting logic into isolated classes like Service Objects and Query Objects, you can write faster, more focused unit tests instead of relying solely on heavy integration tests.

When should I use a Service Object instead of a model method?

Use a Service Object for multi-step operations, side effects like sending emails or tracking analytics, and business logic that coordinates between multiple models or external APIs.

How does this skill help with non-RESTful controller actions?

It identifies verbs that aren't standard CRUD (like 'archive' or 'publish') and provides a strategy to extract them into dedicated RESTful controllers, keeping the routing table clean.

What defines a fat controller in Ruby on Rails?

A fat controller typically contains actions exceeding 10 lines, includes direct business logic, handles complex multi-model queries, or manages non-RESTful custom actions that obscure the controller's primary purpose.

API開発

Refactors large Ruby on Rails controllers into lean, maintainable components using proven architectural patterns.

This skill transforms bloated Rails controllers into efficient traffic cops by systematically delegating logic to specialized objects. It provides a robust decision framework to identify and extract business logic into service objects, complex queries into query objects, and view logic into presenters. By enforcing RESTful principles and a 10-line action limit, it helps developers eliminate technical debt, improve testability, and adhere to industry-standard Ruby on Rails architectural patterns.
