Re: Lookups

['Adam Johnson' via Django developers (Contributions to Django itself)]

Hi!

I think you've found the wrong mailing list for this post. This mailing
list is for discussing the development of Django itself, not for support
using Django. This means the discussions of bugs and features in Django
itself, rather than in your code using it. People on this list are unlikely
to answer your support query with their limited time and energy.

For support, please follow the "Getting Help" page:
https://docs.djangoproject.com/en/stable/faq/help/ . This will help you
find people who are willing to support you, and to ask your question in a
way that makes it easy for them to answer.

Thanks for your understanding and all the best,

Adam

Thanks for pointing me to that ticket -- I've composed a short patch that I
believe addresses the issue. I've attached it to the ticket for review.

This might be another variant on #5937. If so, it's at least a known
issue and will be fixed as part of queryset-refactor.
