Error when adding a warning before deleting a django model record
I am looking to popup a model warning about the deletion of a model record, however when looping into a table, all links lead to delete the very first record in the table, what I am doing wrong?

Django DurationField and 00:00:00 versus NULL
Using Django 3.2.7, python 3.9.x and Mysql 8.x. With models like this: class Object(models.Model): period = models.DurationField('Period', null=False, blank=False, default=timedelta(days=1)) class Subobject(models.Model): object = models.ForeignKey(Object, null=False, blank=False, on_delete=models.CASCASE) period = models.DurationField('Period', null=True, blank=True) and the following query: sub_objs = Subobject.objects.select_related( 'object' ).annotate( actual_period=Case( When( period__isnull=False, then=F('period') ), default=F('object__period'), output_fields=models.DurationField() ) ).filter( actual_period__gte=timedelta(seconds=3600) ) Which could be humanly translated as: "for each subobject, assign a variable named actual_period, whose value is period when found 'locally' in each object, with a fallback to the parent object.period property when not; then filter, etc." This works, but let us imagine a case where a subobject has to have a period property set to "no time at all", i.e., a timedelta == 0 seconds. I tried setting a subobject.period field to 00:00:00 in the admin, or to timedelta(seconds=0) programmatically, and it seems django (Mysql?) always considers such a timedelta as being null. The consequence being that, in the above query, the parent object's period property is applied in the annotation. Is this working as intended? Is there a way to have django/mysql consider that a "zero-time timedelta" is not a null value? -
