Rails Code Conventions

Category: Engineering  ·  Sub-category: backend  ·  Last updated:
lang:rubytype:review
A daily checklist for writing clean Rails code, covering design principles (DRY, YAGNI, PORO, CoC, KISS), per-path rules (models, services, workers, controllers), structured logging, and comment discipline. Defers style and formatting to the project's configured linter(s). Use when writing, reviewing, or refactoring Ruby on Rails code, or when asked about Rails best practices, clean code, or code quality. Trigger words: code review, refactor, RoR, clean code, best practices, Ruby on Rails conventions.
