SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rails service objects provide a structured, SOLID approach to encapsulating business logic, moving complex operations out of controllers and models and returning consistent Result objects.

Core Features & Use Cases

  • Encapsulates complex business logic and multi-model interactions
  • Supports interactor-style workflows with testable interfaces and predictable side effects
  • Promotes maintainable, testable code through dependency injection and a uniform Result type

Quick Start

Create a Namespace::ActionService and implement #call to return a Result object

FAQPage Schema
How do I encapsulate complex business logic in Rails service objects?

Rails service objects move complex operations out of controllers and models using a simple public interface, dependency injection, and consistent Result objects for predictable side effects and testability.

What is the best way to structure interactor-style workflows in a Rails application?

Interactor-style workflows in Rails are structured by creating a service object with a single public #call method that handles multi-model transactions and returns a uniform Result type for predictable outcomes.

When do I need service objects in Rails for multi-model transactions?

Rails service objects are needed when controllers must delegate complex operations involving multi-model transactions, ensuring business logic remains maintainable, testable, and isolated from routing concerns.

Does this service object pattern support dependency injection for RSpec testing?

Yes, the service object pattern enforces dependency injection, which allows you to mock dependencies easily in RSpec tests and verify business logic through a consistent Result object interface.

How do I return consistent results from Rails service objects?

Rails service objects return consistent Result objects from the #call method, standardizing success and failure states across complex operations so controllers can handle outcomes predictably without deep nested conditionals.

Can I use service objects to follow SOLID design patterns in Rails?

Yes, service objects in Rails promote SOLID design patterns by enforcing single responsibility through isolated business logic, dependency injection for inversion of control, and a simple public interface.
