When excluding instances where the related model has a certain field value
instances where no related model exists are excluded as well. This happens
with sqlite 3.16.2 on mac os.
Using postgresql with psycopg2 I was unable to reproduce the issue.
{{{
from django.db import models
class A(models.Model):
pass
class B(models.Model):
a = models.OneToOneField(A)
value = models.IntegerField()
def test():
A.objects.all().delete()
B.objects.all().delete()
A.objects.create()
assert A.objects.exclude(b__value=12345).count() == 1, "We expect to
get one A but got zero."
}}}
