Rails apps often suffer from inefficient Active Record queries, missing real-time updates, and slow background job processing. This Skill provides patterns to optimize data access, implement real-time UI with Turbo Frames/Streams, wire up Action Cable for WebSockets, and orchestrate background jobs with Sidekiq, all while maintaining testable Rails 7+ codebases.
Create a new Rails 7 project, apply ActiveRecord includes to optimize queries, enable Turbo Frames/Streams for partial updates, and set up a basic Sidekiq-backed background job workflow.

Fix ActiveRecord N+1 queries by applying includes and eager_load to preload associations. This prevents per-record database hits during index rendering and improves data access performance.
Implement partial page updates using Turbo Frames and Streams to refresh isolated DOM sections. This approach replaces full page reloads with targeted real-time UI updates without writing custom JavaScript.
Set up Sidekiq background jobs by configuring asynchronous processing queues in Rails. This orchestrates reliable background job handling for heavy tasks outside the request-response cycle.
Action Cable works with Turbo Streams to broadcast real-time WebSockets updates. Wiring Action Cable channels broadcasts server-side changes directly to connected clients for live UI features.
Write RSpec test suites covering models, controllers, and feature specs to catch regressions. Comprehensive testing ensures ActiveRecord query changes and Turbo integration maintain expected behavior.
Apply these Rails optimization patterns within migration-safe workflows by structuring database changes carefully. This ensures ActiveRecord query improvements and background job additions deploy without breaking existing schema.
