Changes between Initial Version and Version 1 of Ticket #28047

-              initial
+              v1
 I have this (simplified)
+{{{#!python
 from django.db import models
 class Foo(models.Model):
     class Meta:
 …
         app_label = 'inventory'
     foo = models.OneToOneField(Foo, primary_key=True, on_delete=models.CASCADE)
+}}}
 Of course you need an app named inventory. But just use this and try to create a query set like this:
+{{{#!python
 Bar.objects.filter(foo__in=Foo.objects.all())
+}}}
 Obviously I had different criteria.
