rails-knowledge-patch

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real Rails 8.0–8.1 API, configuration, and tooling changes so developers and coding agents do not produce or rely on outdated patterns.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
