Hi!
I think you've found the wrong mailing list for this post. This mailing
list is for 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. Read more on the mailing
lists at https://www.djangoproject.com/community/
For support, please use the NEW Django forum at
https://forum.djangoproject.com , django-users mailing list, or IRC #django
on Freenode, or a site like Stack Overflow. There are people out there
willing to help on those channels, but they might not respond if you don't
ask your question well. Stack Overflow's question guide can help you frame
it well: https://stackoverflow.com/help/how-to-ask .
Also if you haven't read it, please take a look at Django's Code of
Conduct: https://www.djangoproject.com/conduct/ . These are our "ground
rules" for working well as a community, and will help you get the most out
of Django and our fantastic community.
Thanks for your understanding,
Adam
