An example of an AI chatbot conversation about transaction locking in Django ORM.
What is transaction locking in Django ORM?
Transaction locking in Django ORM is a mechanism to prevent concurrent transactions from interfering with each other, ensuring data integrity.
How does it work in practice?
In practice, when a transaction is initiated, Django can lock the rows being modified, preventing other transactions from accessing them until the first one is complete.
Can you give an example of how to implement it?
Sure! You can use the select_for_update() method in your query to lock the selected rows. For example: MyModel.objects.select_for_update().get(id=1).
What are the potential downsides of using transaction locking?
The main downsides include potential deadlocks and reduced concurrency, as other transactions may be blocked while waiting for the lock to be released.
