I have two models class Meet(models.Model): submitted=models.BooleanField(default=False)
class MeetParticipationSession(models.Model): meet=models.ForeignKey(Meet) submitted=models.BooleanField(default=False) question 1: How do i find Meet objects that don't have a MeetSession pointing to them. In SQL I would do it as follows: select a.* from meet_meet a where a.id not in (select distinct b.meet_id from meet_meetparticipationsession b) question 2: How do I find all the meets that have been submitted minus those for which there is a meet participation session that has been submitted.
