How does transaction management work in Django?

Django's transaction management allows you to group multiple database operations into a single unit of work. This ensures that either all operations succeed or none do, maintaining data integrity.

Can you explain the difference between atomic and non-atomic transactions?

Sure! An atomic transaction ensures that all operations within it are completed successfully before committing. If any operation fails, the entire transaction is rolled back. Non-atomic transactions, on the other hand, do not guarantee this, which can lead to partial updates.

How do I implement an atomic transaction in my Django view?

You can use the @transaction.atomic decorator or the transaction.atomic() context manager to wrap your view logic. This will ensure that all database operations within that block are treated as a single transaction.

What happens if an exception occurs during a transaction?

If an exception occurs during a transaction, Django will automatically roll back all changes made during that transaction, ensuring that your database remains consistent.
