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.
