Ruby Rails Application

aj-geddes/useful-ai-prompts

This covers the full Rails stack from project setup through authentication, with reference guides for models, controllers, migrations, and Active Record queries. You'll want this when building any Rails API or full-stack app that needs proper MVC architecture, database relationships, and JWT auth. The best practices section is solid on the usual Rails pitfalls like N+1 queries and putting business logic in controllers. It's focused on API mode with PostgreSQL, which is probably the most common Rails setup these days. The references walk through serializers and RESTful patterns, so it's clearly aimed at developers who know Ruby but want Rails conventions done right.
