Ruby

Purpose

Write Ruby that stays readable as it grows: small objects with clear responsibilities, controllers that stay thin, and ActiveRecord queries that do not quietly issue a query per row.

When to Use

• Writing or reviewing Ruby and Rails code.
• Refactoring fat models or fat controllers.
• Diagnosing slow endpoints caused by ActiveRecord.
• Structuring an RSpec suite.
• Designing background jobs and their retry semantics.
