How to solve a problem in python3, Django?

Question

Django

There is a model file https://gist.github.com/octoberweb/87700041bb16439... containing the Event model. The event can take place either on the same day when there is date and no date_end, or in the period, for example, from 06/14/17 to 06/18/17, then date_end is the end date of the event.
It is necessary to make it so that it would be possible with the help of the commands:
Event.objects.current() to get the current events for today's date.
Event.objects.archive() get all past events.

Answer 1

Offhand, all the past something like this:

now = datetime.date.today()

q = Q(date_end__isnull=False)&Q(date_end__lte=now)
q |= Q(date_end__isnull=True)&Q(date__lte=now)

qs = Event.objects.filter(q).distinct()

Current events - same...
