rails-transactions

What problem does it solve?

This Skill teaches how to implement database transactions to guarantee atomicity and data integrity across multiple models.

Core Features & Use Cases

• Basic & Nested Transactions: Wrap multi-model operations in a transaction.
• Explicit Rollback & Isolation: Use rollback and isolation levels where needed.
• Error Handling Within Transactions: Graceful handling and compensating actions.

Quick Start

Implement a funds-transfer method that uses ActiveRecord::Base.transaction to ensure both debit and credit either complete together, with a fallback rollback if an error occurs.
