For Rails conventions, this style guides you toward fat models and thin controllers to keep business logic encapsulated. It recommends database-backed solutions over complex abstractions, minimizing external gems and favoring Minitest for testing to ensure maintainability.

To align with this Rails style, use simple naming conventions, maintain REST purity in controllers, and push logic into fat models. Avoid excessive metaprogramming and clever tricks; instead, favor clear, explicit code that relies on database-backed solutions for maintainability.

Yes, the 37signals Rails style explicitly incorporates Minitest for testing. This choice aligns with their best practices of minimizing external gems and relying on the framework's built-in capabilities to maintain a simple, clean codebase.

You should avoid adding external gems when a database-backed solution or native Rails feature can achieve the same result. The 37signals coding style strongly recommends minimal use of external dependencies to keep your Ruby code simple, maintainable, and easy to upgrade.

Yes, you can apply these Rails conventions to existing applications by refactoring complex controllers into thin endpoints and moving business logic into fat models. This style guide provides the architectural recommendations needed to align your code with REST purity and 37signals principles.
