pub_date = models.DateField(\"date published\")

Answer 1

obj = Edition.objects.latest('pub_date')

You can also simplify things by putting get_latest_by in the model's Meta, then you'll be able to do

obj = Edition.objects.latest()

See the docs for more info. You'll probably also want to set the ordering Meta option.
