What would be the best way to handle situations that involves keeping records/history of fields based on the timerange_uuid?
Well, I think, I have run out of ideas and would like someone to help me explain using the example below. I have three tables (Timerange_uuid - should be an enum, and Person, and Organization), I want each time the Person changes an Organization (the Person can change organisations depending on the kind of work he/she is doing) the person's table should keep records of all Organizations that the person has served since the start date to end date - basing on the Timerange_uuid, and I can't figure out what would be the most appropriate solution to handle this situation. Timerange_uuid (enum) class Timerange_uuid(models.Model): start = models.DateTimeField(auto_now_add=True) stop = models.DateTimeField(auto_now=True) u = models.UUIDField(default=uuid.uuid4) class Meta: abstract = True Person class Person(models.Model): group_id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) organization = ??? ## timerange_uuid[] -- organization_id Organization class Organization(models.Model): organization_id = models.UUIDField(primary_key=True ,default=uuid.uuid4, editable=False) -

Django - solving a possible n + 1 problem
One of my views is hitting the db a lot with a particular query. Scout-apm identifies it as a possible n+1 query. I'm not sure that is the problem, but it is a problem nonetheless. My original code was: models.py class Grade(models.Model): score = models.CharField(max_length=4, blank=True) testing = models.ForeignKey(Testing, on_delete=models.CASCADE) student = models.ForeignKey(Student, on_delete=models.CASCADE) classroom = models.ForeignKey(Purpose, on_delete=models.CASCADE) time_created = models.DateField( auto_now=False, auto_now_add=False, default=timezone.now) Class Testing(models.Model): name = models.CharField(max_length=20, blank=True) omit = models.BooleanField(default=False) Class Classroom(models.Model): name = models.CharField(max_length=20, blank=True) views.py def allgrades(request, student_id): classrooms = Classroom.objects.all() for c in classrooms: q = Grade.objects.filter( student=student_id, classroom=c.id, testing__omit="False").order_by('-time_created') if q.exists(): if len(q) < 3: qn = q.first() else: .... The offending queries come from the if q.exists(): and qn = q.first(). I don't know if this falls in the category of n + 1, but the number of queries decreases from around 1300 to around 400 if I get rid of the if q.exists(): and qn = q.first() I need the functionality of these statements. Since I'm doing something with q, I need to check that it exists. And as the code shows, I may want to only include the newest object. Is there a less expensive way to deal with this? -
