SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill codifies the service object pattern in Rails apps using dry-monads to manage multi-step business logic, improving maintainability, testability, and separation of concerns.

Core Features & Use Cases

  • Guides when to use service objects: when business logic touches multiple models, involves external calls, or requires transactional boundaries.
  • Structure & Patterns: demonstrates the Namespace::Operation::Action convention and how to compose steps with do-notation.
  • Testing & Integration: provides testing approaches and controller integration patterns to ensure safe, observable changes.

Quick Start

Instantiate and run a service object via its operation class, then handle Success or Failure results in the controller or workflow.

FAQPage Schema
When should I use Rails service objects instead of models or controllers?▼

Use Rails service objects when business logic touches multiple models, involves external calls, or requires transactional boundaries, keeping complex rules out of controllers and models for better testability.

How do I structure a Rails service object with dry-monads?▼

Structure Rails service objects using the Namespace::Operation::Action convention, composing multi-step business logic with dry-monads do-notation to handle Success and Failure results cleanly.

What is the best way to test Rails service objects using dry-monads?▼

Test Rails service objects by instantiating the operation class, using dependency injection for mocks, and asserting Success or Failure monad results to verify multi-step business logic and external calls.

How do I integrate dry-monads service objects with Rails controllers?▼

Integrate dry-monads service objects in Rails controllers by instantiating the operation class, executing it, and pattern matching the Success or Failure results to render appropriate responses or redirect.

Does using dry-monads for Rails service objects require dependency injection?▼

Yes, this Rails service object architecture enforces using dry-monads alongside dependency injection to isolate external calls and ensure multi-step business logic is fully testable and maintainable.
