What do you think this error is telling you?

See Built-in Exceptions — Python 3.10.5 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!
