Hello,
I am looking for a model/serializer/view for a self join. I can have nested
paernt child relationship.
The one I am trying:
model:
class ParentChild(models.Model):
parent=models.CharField(max_length=100, blank=False, default='', unique
=True)
child=models.Foreig

As I explained, there's nothing different in a self-join than
I see nothing on this page that is in the slightest bit related to my
question... Does anyone know if there is a way in the django orm to
accomplish my query above?
Thanks.

I'm trying, without a great deal of success, to perform a simple self
join using the django orm. I'm pretty sure the F() function is not
the answer. I believe this only allows you to compare two field
within the same model instance, not to compare fields within 2
instances of the same
Just started in the last few days with django and am having a little
trouble with the orm. Is it possible to do a self join with an
aggregate? My query looks like the following (apologies for the
generic names):
SELECT t.field1, c.field2, c.field3, t.field4, t.field5, (t.field4/
t.field5) as

Is it possible to do a self join using QuerySet?
I'm looking to simulate a query like this:
SELECT b.created_on, SUM(a.vote)
FROM votes a JOIN votes b ON a.created_on <= b.created_on
WHERE a.object_id = 1
GROUP BY 1
Which finds the sums for votes before the datetime of e
13 matches
