How can I perform bulk updates in Django?

You can use the bulk_update method in Django to update multiple records at once. Would you like an example?

Yes, please provide an example of using bulk_update.

Sure! Here's a simple example:

from myapp.models import MyModel

# Assuming you have a list of instances to update
instances = [
    MyModel(id=1, field='new_value1'),
    MyModel(id=2, field='new_value2'),
]

# Perform the bulk update
MyModel.objects.bulk_update(instances, ['field'])

This will update the 'field' for the instances with ids 1 and 2.

What if I want to update multiple fields at once?

You can specify multiple fields in the bulk_update method like this:

MyModel.objects.bulk_update(instances, ['field1', 'field2'])

Just make sure your instances have the updated values for those fields.
