rails-migrations

What problem does it solve?

Rails migrations are essential but can be error-prone and hard to manage across environments. This skill provides structured guidance for creating, altering, and rolling back migrations safely, with emphasis on reversibility and best practices.

Core Features & Use Cases

• Generator-based migrations and up/down reversibility
• Managing references, foreign keys, and indexes
• Zero-downtime strategies and complex patterns (UUIDs, partitioning, enums, join tables)
• Use cases include adding columns, creating join tables, and refactoring schemas across development, staging, and production

Quick Start

Generate a new Rails migration and apply it to the database.
