How can I use signals in Django for bulk operations?

In Django, you can use signals to perform actions before or after bulk operations like create, update, or delete. For example, you can connect to the pre_save or post_save signals to trigger custom logic.

Can you give me an example of using a signal with bulk_create?

Sure! You can define a signal receiver function that listens to the post_save signal. When you call bulk_create, the signal will trigger after the objects are created.

What if I want to perform actions after bulk_update?

You can use the post_save signal as well. Just ensure your receiver checks if the instance is part of a bulk update by checking the update_fields attribute.

Are there any performance considerations I should be aware of?

Yes, using signals can add overhead, especially with bulk operations. It's important to keep your signal logic efficient to avoid slowing down the bulk operation.
