🔐 Wrap Critical Changes in Transactions

Use database transactions to ensure data integrity when performing multiple related operations. If any step fails, the transaction rolls back everything to avoid partial updates. Wrap calls in transaction blocks and handle exceptions as needed.

ApplicationRecord.transaction do
  order.update!(status: :paid)
  Payment.create!(order: order, amount: order.total_price)
  Inventory.decrement_stock!(order.items)
end
