Django: Boolean field not getting updated

I have a model which has a latest field to determine if a particular instance is the latest definition.

When adding a new row to the db I want to make sure to mark latest as false for the already existing record. 

latest_version = Segment.objects.filter(title=title, latest=True).first()

if latest_version:
    latest_version.latest = False
    latest_version.save()

This seems relatively straight forward but the latest field will not update and stays as True.

I think you are looking at the wrong object for the update. I think what you are looking for is:

Segment.objects.filter(title=title, latest=True).last()
