Rails Expert

A straightforward Rails 7+ implementation guide that enforces good habits: eager loading associations to kill N+1 queries, using Turbo Frames for partial updates instead of full page reloads, and pushing slow work to Sidekiq. The workflow is opinionated in useful ways, like demanding RSpec coverage above 95% and adding indexes on every filtered column. Includes ready-to-use templates for common patterns like strong parameters and background jobs. Best for teams who want guardrails around performance and testing rather than just scaffolding code. The reference system lets you pull in deeper docs on Hotwire or Active Record only when you need them.

Core Workflow

Analyze requirements — Identify models, routes, real-time needs, background jobs
Scaffold resources — rails generate model User name:string email:string, rails generate controller Users
Run migrations — rails db:migrate and verify schema with rails db:schema:dump
- If migration fails: inspect db/schema.rb for conflicts, rollback with rails db:rollback, fix and retry
Implement — Write controllers, models, add Hotwire (see Reference Guide below)
Validate — bundle exec rspec must pass; bundle exec rubocop for style
- If specs fail: check error output, fix failing examples, re-run with --format documentation for detail
- If N+1 queries surface during review: add includes/eager_load (see Common Patterns) and re-run specs
Optimize — Audit for N+1 queries, add missing indexes, add caching
