sorting a ListField in mongoengine

I have a model in mongoengine defined like this:

class Task(Document):

    name = StringField(required=True, unique=True)
    frequency = IntField(required=True)
    quantity = IntField()
    units = StringField()
    events = ListField(DateTimeField(default=datetime.datetime.now))

How can I get the latest event? I've tried the following to no success:

def latest(self):
    return self.events.sort()[-1]

Instead of returning the events sorted sort returns None

You could just use the Mongoengine SortedListField instead of ListField, here is the doc

Then you could simply return self.events or its reverse if you wish as well
