You’re going to need to provide more detail and be more descriptive about the problem you’re having.

These details need to include what you’re seeing that you don’t expect to see - or what you’re not seeing that you’re expecting to see.

Include all error messages that you may be getting in the console where you’re running runserver.

Post your ModelAdmin class that you’re saying is not working.

Side note, Don’t do this:

The form has already been instantiated from the POST data earlier in the view processing, along with having been validated.

Also, since you’re saving the form here, you should not be calling super in form_valid. After you’ve done your work here, return your HttpResponseRedirect to your success_url.

If you’re not familiar with the Classy Class-Based Views site, I suggest you take some time reading it to help you understand what each of the functions being performed do. (Personally, I find that site to be more useful than the official docs when it comes to understanding the CBVs.)
