Django: Adding “NULLS LAST” to query

Question

I would like to sort a model by using Postgresql\'s \"NULLS LAST\" option. How could it be done?

I tried something like

MyModel.objects.all().extra(ord

Answer 1

Closest thing I've found is doing it on two steps. First ordering on the populated field and then on the nulls:

Via this gist (itself via these django logs):

all_projects = Project.objects.select_related().filter(
    company=company).order_by('-date_due')

q = all_projects.extra(select={'date_due_null': 'date_due is null'})
q = q.extra(order_by=['date_due_null'])
print q.query

Caution: note the warnings regarding extra(), and that it may be deprecated in the future.
