Rails Cheatsheet

Rails Cheatsheet puts a fast, searchable Rails 8 reference right in your browser toolbar — no more tab-switching to look up syntax you already sort of remember. What's inside: 50+ snippets across 14 categories: Routing, Active Record, Associations, Migrations, Validations, Controllers, Views & Helpers, Active Job, Active Storage, Testing, Caching, Security, I18n, and Console/CLI commands One-click copy on every snippet — no more retyping boilerplate from memory Instant search across all snippets and categories Favorite your most-used patterns for one-click access later Every entry links directly to the official Rails guides or API docs for the full explanation Collapsible sidebar so the snippet grid can use the full popup width Why this exists: Official Rails docs are excellent for deep dives, but sometimes you just need the syntax for has_many :through or how to set up a Solid Queue job without leaving your current tab. This extension is a quick-recall layer on top of the docs you already trust — not a replacement for them. Privacy: This extension makes no network requests and collects no data. Favorites and your sidebar preference are stored locally in your browser via chrome.storage.local and never leave your device. Built for Rails 8.x conventions. Feedback and category requests welcome.
