Comment (by Mariusz Felisiak):
Replying to [ticket:32651 Jaap Roes]:
> I'm in the process of upgrading a project from Django 3.1 to 3.2 and one
of the tests keeps crashing. I reduced the code to the following
statement:
>
> {{{
> Q() & Q(Exists(Book.objects.all()))
> }}}
>
> This worked correctly in Django 3.1.
>
> I found this ticket: #32548 and can confirm (that after some struggles
related to incompatibilities in 3rd party packges) I was able to get the
tests to pass on Django main. Is it possible to backport the fix to Django
3.2?
Thanks I didn't notice that it's a regression in
466920f6d726eee90d5566e0a9948e92b33a122e (backported in
0e2979e95d0f68f28c92c84c14655e7510d4e789). I will prepare a backport to
Django 3.2.
Let's close it as a duplicate of #32548.
