SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Many Rails projects drift away from best‑practice conventions, leading to hard‑to‑maintain code, hidden bugs, and unnecessary infrastructure complexity. This Skill helps teams stay aligned with Rails idioms and modern Rails 7/8 conventions.

Core Features & Use Cases

  • Iron Laws: Enforces core Rails principles such as controller responsibility, explicit parameter shaping, and boring callbacks.
  • Solid Stack Guidance: Recommends Solid Queue, Solid Cache, and Solid Cable alternatives to Redis for moderate‑throughput workloads.
  • Quick Reference & References: Provides ready‑to‑use code snippets, pattern checklists, and extensive markdown references covering controllers, callbacks, Active Record scopes, async queries, authentication, testing, deployment, and more.
  • Use Case Example: When adding a new controller, run this Skill to verify that callbacks are simple, parameters are strongly permitted, and background jobs use the appropriate queue.

Quick Start

Use the rails-idioms skill to analyze your Rails app and suggest idiomatic improvements.

Frequently Asked Questions about rails-idioms

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What are the idiomatic Rails patterns for controllers and models?▼

Idiomatic Rails patterns enforce controller responsibility, explicit parameter shaping, and simple Active Record callbacks. Maintaining these conventions prevents hidden bugs and keeps application architecture aligned with modern Rails 7 and 8 standards.

How do I check my Rails 8 code for non-idiomatic patterns?▼

You can check Rails 8 code by analyzing controllers, models, jobs, and routes against Rails Iron Laws. This process verifies strong parameters, identifies complex callbacks, and recommends modern queue alternatives without requiring external linting tools.

Does Rails 8 require Redis for background jobs and caching?▼

Rails 8 does not strictly require Redis. For moderate-throughput workloads, you can use Solid Queue, Solid Cache, and Solid Cable alternatives to reduce infrastructure complexity while maintaining reliable background processing and caching.

What is the best way to simplify complex Active Record callbacks?▼

The best way to simplify Active Record callbacks is to enforce boring, straightforward callback patterns and move complex logic into background jobs. Curated reference checklists help identify non-idiomatic callbacks and suggest safer alternatives.

When should I use Solid Queue instead of Redis in Rails?▼

You should use Solid Queue instead of Redis when handling moderate-throughput workloads in Rails 7.x or 8.x. Switching to Solid Queue, Solid Cache, and Solid Cable reduces unnecessary infrastructure complexity while maintaining reliable async processing.
