I’m writing a forum using Django and I can’t figure out why after completing the form, the created Thread object doesn’t get an automatically assigned ID.
Error:

P.S. I have another app in my django project which has its own views and models, but they don’t really play a big role in what’s happening during the Thread creation, so I left them out.
I’m a newcomer, so bear with me
