The Unofficial 37signals/DHH Rails Style Guide

About This Document

This style guide was generated by Claude Code through deep analysis of the Fizzy codebase - 37signals' open-source project management tool.

Why Fizzy matters: While 37signals has long advocated for "vanilla Rails" and opinionated software design, their production codebases (Basecamp, HEY, etc.) have historically been closed source. Fizzy changes that. For the first time, developers can study a real 37signals/DHH-style Rails application - not just blog posts and conference talks, but actual production code with all its patterns, trade-offs, and deliberate omissions.

How this was created: Claude Code analyzed the entire codebase - routes, controllers, models, concerns, views, JavaScript, CSS, tests, and configuration. The goal was to extract not just what patterns are used, but why - inferring philosophy from implementation choices.

Integration of TinyMCE in Rails 7 with Turbo Drive Support

Since Rails 7 the turbo-rails library is included by default. Turbo Drive intercepts link clicks and form submits. It makes sure that only the <body> part of the page is rerendered instead of the whole page.

This leads to TinyMCE not being properly detached and reattached when a Turbo Drive response is rendered. The textarea will appear without the TinyMCE editor. In this post we expand on the tinymce-rails gem with a Stimulus controller to prevent this issue. The controller helps to reattach TinyMCE and respects the settings in config/tinymce.yml.
