How can I use bulk_create in Django?

You can use the bulk_create method in Django to insert multiple records into the database efficiently. It takes a list of model instances and saves them in a single query.

Can you show me a code example?

Sure! Here's a simple example:

from myapp.models import MyModel

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

# Use bulk_create to save them all at once
MyModel.objects.bulk_create(objects)

Are there any limitations I should be aware of?

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 doesn't handle auto-incrementing fields.

What if I want to update existing records?

For updating existing records, you would typically use update() or loop through the instances and call save() on each one, as bulk_create is only for creating new records.
