Following is the views.py and on runserver getting error as the traceback attached below.

def Create(request):
    form = ListForm()

            ListFormDataForSave = List(

What do you think this error is telling you?

See Built-in Exceptions — Python 3.12.0 documentation

Side note: If you use a ModelForm, this (below) all becomes unnecessary.

Side note #2 - To avoid confusion, i would definitely not recommend ever having a class or model named List.

Fine. Will use ModelForm. - Thank you!
Will try to rename the model name to be something else later - thanks!
