Comment:
Hi,
I can indeed reproduce the issue on the 1.5 branch, using the two
following models:
{{{#!python
from django.db import models
class Foo(models.Model):
foo = models.CharField(max_length=1, db_index=True, unique=True)
class Bar(models.Model):
foo = models.ForeignKey(Foo, to_field='foo')
}}}
With these models, the following code shows the issue: `assert
Bar.objects.filter(foo__in=Foo.objects.all()).count()` (this requires
having created one model of each kind in the database).
Having this code, I was able to track down the commit that fixed this
issue in the master branch (also present in 1.6, as it turns out):
97774429aeb54df4c09895c07cd1b09e70201f7d.
Seeing as this issue is not a regression (and therefore its fix is
unlikely to get backported), I'm going to mark this ticket as `fixed`.
Feel free to reopen the ticket if you think otherwise of course.
Thanks for your report.
