layouts-and-rendering

What problem does it solve?

This Skill provides expert guidance to ensure your Rails application renders views correctly, efficiently, and with the appropriate HTTP responses, preventing common errors like "double render" and ensuring seamless integration with Turbo/Hotwire.

Core Features & Use Cases

• Render vs. Redirect: Clearly distinguishes between render and redirect_to for correct request handling.
• Partials & Locals: Enforces best practices for partials, emphasizing explicit local variable passing to avoid coupling.
• Layout Management: Covers layout selection, inheritance, and nested layouts.
• Turbo/Hotwire Status Codes: Ensures correct HTTP status codes (422, 303) for Turbo-aware responses.
• Use Case: When building a form that can be edited or created, this Skill helps you correctly handle both successful submissions (redirecting with 303) and validation errors (re-rendering the form with 422), ensuring a smooth user experience with Turbo.

Quick Start

Use the layouts-and-rendering skill to correctly render a form with validation errors, ensuring the form data is preserved and the correct HTTP status code is used.
