#11557 closed New feature (fixed)

Description

The ordering attribute of the Meta class is a tuple so that the default ordering can use multiple columns. It would be nice if get_latest_by was the same way. However, it currently must be a string specifying a single column.

This is especially important when specifying both, since you would typically want the latest item to correspond with the last item in a list ordered according to ordering.
