Question

Specifically, I have a model that has a field like this

pub_date = models.DateField('date published') 

I want to be able to easily grab the object with the most recent pub_date. What is the easiest/best way to do this?

Would something like the following do what I want?

Edition.objects.order_by('pub_date')[:-1] 

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.
