How can I perform a bulk insert using Django ORM?

How can I perform a bulk insert using Django ORM?

You can use the bulk_create() method in Django ORM to perform bulk inserts. It allows you to insert multiple records at once.

Can you show me an example of how to use bulk_create()?

Sure! Here's a simple example:

from myapp.models import MyModel

# Create a list of objects to insert
objects = [MyModel(field1='value1'), MyModel(field1='value2')]

# Perform the bulk insert
MyModel.objects.bulk_create(objects)

Are there any limitations I should be aware of when using bulk_create()?

Yes, bulk_create() does not call the save() method on each instance, so signals like pre_save and post_save won't be triggered. Also, it may not handle unique constraints as expected.

What if I want to update existing records during the bulk operation?

For updating existing records, you would typically need to loop through the records and use update() or handle it in a separate query, as bulk_create() only inserts new records.
