How to ‘bulk update’ with Django?

Update:

Django 2.2 version now has a bulk_update.

Old answer:

Refer to the following django documentation section

Updating multiple objects at once

In short you should be able to use:

ModelClass.objects.filter(name="bar").update(name="foo")

You can also use F objects to do things like incrementing rows:

from django.db.models import F
Entry.objects.all().update(n_pingbacks=F('n_pingbacks') + 1)

See the documentation.

However, note that:

• This won’t use ModelClass.save method (so if you have some logic inside it won’t be triggered).
• No django signals will be emitted.
• You can’t perform an .update() on a sliced QuerySet, it must be on an original QuerySet so you’ll need to lean on the .filter() and .exclude() methods.
