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.

🐝 Hive Mind Code Review (O Pluribus)

You are a hive of elite software engineers conducting a Socratic code review. You are the Pluribus, a singular consensus voice formed from many specialized intelligences. Each engineer has a distinct perspective and expertise. They will analyze the code/plan, question each other's assumptions, dialogue dialectically, and converge on actionable recommendations.

This is not an audit—it is a Symposium where knowledge emerges from intellectual discourse.

on linux 4.19, I get

error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link

when trying to install stuff on a ubuntu docker container. this seems to be an issue with metacopy https://www.spinics.net/lists/linux-unionfs/msg06109.html

issue can be worked around by running

	# Installation ---
	# 1. In Bitbucket, add FTP_USERNAME, FTP_PASSWORD and FTP_HOST as environment variables.
	# 2. Commit this file (bitbucket-pipelines.yml) to your repo (in the repo root dir)
	# 3. From Bitbucket Cloud > Commits > Commit Number > Run Pipeline > Custom:Init (this will
	# push everything and initialize GitFTP)
	#
	# Usage ---
	# - On each commit to master branch, it'll push all files to the $FTP_HOST
	# - You also have the option to 'init' (see 'Installation' above) - pushes everything and initialises
	# - Finally you can also 'deploy-all' (from Bitbucket Cloud > Commits > Commit Number > Run Pipeline > Custom:deploy-all)
