8. get_latest_by
|
|
|
|
Models can have a ``get_latest_by`` attribute, which should be set to the name
|
|
of a ``DateField`` or ``DateTimeField``. If ``get_latest_by`` exists, the
|
|
model's manager will get a ``latest()`` method, which will return the latest
|
|
object in the database according to that field. "Latest" means "having the date
|
|
farthest into the future."
