Answer 1

I suspect class UserForm should be model form. You may want to change fields, but it should be derived from `ModelForm.

So change form definition to

class UserForm(forms.ModelForm):    class Meta:        model = User        fields = [...] # list of fields you want from model     #or define fields that you want.    ....
