Django Order By Date, but have "None" at end?

Django 1.11 added this as a native feature. It's a little convoluted. It is documented.

Ordered with only one field, ascending:

wo = Work_Order.objects.order_by(F('dateWORequired').asc(nulls_last=True))

Ordered using two fields, both descending:

wo = Work_Order.objects.order_by(F('dateWORequired').desc(nulls_last=True), F('anotherfield').desc(nulls_last=True))

q = q.extra(select={
        'date_is_null': 'dateWORequired IS NULL',
    },
    order_by=['date_is_null','dateWORequired'],
)

You might need a - before the date_is_null in the order_by portion, but that's how you can control the behavior.
