What are transactions in Django and how do they work?

Transactions in Django are used to ensure that a series of database operations are executed in a safe and consistent manner. They allow you to group multiple operations so that they either all succeed or all fail, maintaining data integrity.

Can you explain how to use the atomic context manager for transactions?

Sure! The atomic context manager in Django allows you to wrap a block of code in a transaction. If an exception occurs within that block, all changes made during that transaction will be rolled back.

What happens if I don't use transactions in my Django app?

Without transactions, if an error occurs during a series of database operations, some changes may be saved while others are not, leading to inconsistent data.

Are there any performance implications of using transactions?

Yes, while transactions can ensure data integrity, they may introduce some overhead. It's important to use them judiciously to balance performance and safety.
