Comment (by Jerin Peter George):
I am aware that I can do something similar as you suggested for a
''"workaround"'' to get the desired result. But the real question is
whether this is the expected behavior for the Window function?
I am sure that I can do a similar query using the `Count(...)` expression
as
{{{
from django.db import models
class Musician(models.Model):
name = models.CharField(max_length=50)
class Album(models.Model):
artist = models.ForeignKey(Musician, on_delete=models.CASCADE,
related_name="albums")
name = models.CharField(max_length=100)
qs = Musician.objects.annotate(album_count=models.Count("albums"))
print(qs.get(pk=2).album_count)
}}}
