SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Rails-knowledge-patch fills the gap between model training cutoffs and the real Rails 8.0–8.1 API, configuration, and tooling changes so developers and coding agents do not produce or rely on outdated patterns. It summarizes breaking changes, new defaults, and migration implications that commonly cause runtime errors, deprecated usage, or insecure defaults when upgrading from Rails 7.x.

Core Features & Use Cases

  • Curated diffs and notes highlighting Rails 8.0–8.1 architecture shifts such as Solid Queue/Cache/Cable, Propshaft, and Kamal 2 deployment.
  • Practical migration guidance covering controller params.expect, Active Job continuations, connection pool options, transaction isolation, and schema behavior changes.
  • Reference-driven examples for configuration, database YML extensions, deprecated APIs, and structured event reporting to help code review tools and upgrade scripts.
  • Use Case: Run this patch before generating or reviewing Rails code to detect deprecated patterns, recommend config updates, and produce targeted migration steps.

Quick Start

Load rails-knowledge-patch and ask it to scan your Rails project for incompatible APIs, recommended configuration changes, and step-by-step migration notes for upgrading to Rails 8.0–8.1.

FAQPage Schema
How do I upgrade my Rails 7 application to Rails 8 without runtime errors?▼

Upgrading Rails 7 to Rails 8 requires identifying deprecated APIs, applying configuration updates for caching and asset pipelines, and implementing migration steps for Solid Queue, Propshaft, and params.expect to prevent runtime errors.

What Rails 8 breaking changes affect Active Job and database configurations?▼

Rails 8 breaking changes affect Active Job continuations, connection pool options, transaction isolation, and database YML extensions, requiring configuration updates to maintain stable database and job backend operations.

How do I migrate from Rails 7 asset pipelines to Propshaft?▼

Migrating to Propshaft in Rails 8 involves updating your asset pipeline configuration to replace older gem dependencies, ensuring proper asset compilation and deployment behavior during the Rails 8.0–8.1 upgrade process.

Does Rails 8 support Solid Queue for background jobs and Solid Cache for caching?▼

Yes, Rails 8 supports Solid Queue for background jobs and Solid Cache for caching, replacing external dependencies like Redis and requiring specific database YML extensions and configuration updates for optimal performance.

What is the correct way to use params.expect in Rails 8 controllers?▼

The params.expect method in Rails 8 controllers replaces deprecated strong parameter patterns, requiring targeted migration steps to ensure secure parameter handling and prevent deprecated API usage in upgraded applications.

How do I configure Kamal 2 deployment for a Rails 8 application?▼

Configuring Kamal 2 deployment for Rails 8 involves updating deployment configurations to align with new Rails 8.0–8.1 architecture shifts, ensuring proper integration with Solid Queue, Solid Cache, and Propshaft defaults.
