Overwrite auto_now for unittest

Question

I\'ve defined some timestamps for events in the database as auto_now_add, as the information should be stored with it\'s timestamp the same time the event is st

Answer 1

Another way of handling this is to use a QuerySet update after the instance is created which may be more useful depending upon your use case.

As an update call is performed at the SQL level it will skip validation, signals and and custom save functionality. It will require a secondary database call which can impact performance so it should be used with consideration.

for event in EVENT_TYPES:
    time = datetime.datetime.now() - datetime.timedelta(days=1)
    for i in range(48):
        time = time.replace(hour=i / 2)
        instance = NewEvent(name=event, quantity=i).save()
        NewEvent.objects.filter(pk=instance.pk).update(timestamp=time)
