SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the creation of robust, testable, and maintainable service objects in Rails applications, adhering to SOLID principles and best practices.

Core Features & Use Cases

  • Service Object Generation: Creates well-structured service objects with callable interfaces and error handling.
  • RSpec Test Generation: Automatically writes corresponding RSpec tests for generated services.
  • Use Case: When you need to extract complex business logic from controllers or models into a dedicated, testable unit, or when a user explicitly asks for a service object, interactor, or PORO.

Quick Start

Generate a new service object for creating user entities with associated RSpec tests.

FAQPage Schema
How do I extract business logic from Rails models into service objects?

Generating Rails service objects creates callable units that extract business logic from models or controllers. These objects follow SOLID principles, using Result Objects for error handling to keep controllers and models clean.

What is the best way to generate RSpec tests for Rails service objects?

Generating RSpec tests for Rails service objects automatically writes corresponding test suites alongside the callable interface. This ensures the extracted business logic is immediately testable without manual test scaffolding.

When do I need a service object or interactor in my Rails application?

You need a Rails service object or interactor when extracting complex business logic from controllers or models into a dedicated, testable unit. This is required when adhering to the Single Responsibility Principle for maintainable code.

Does generating Rails service objects require SOLID principles and PORO patterns?

Generating Rails service objects requires adherence to SOLID principles, specifically the Single Responsibility Principle. It uses standard PORO patterns with callable interfaces and Result Objects for structured error handling.

How do I handle errors in Rails service objects without exceptions?

Rails service objects handle errors using Result Objects instead of raising exceptions. This pattern returns structured result data from the callable interface, allowing business logic to manage failures predictably without breaking execution flow.
