Answer 1

Sospecho que la clase UserForm debería ser modelo. Es posible que desee cambiar los campos, pero debe derivarse de `ModelForm.

Así que cambia la definición de la forma a

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

Answer 2

forms.py define campos en corchetes cuadrados como campos = [''campo 1'', ''campo 2'', ...]

class CustomerForm(forms.ModelForm):
class Meta:
model = Customer
fields = [''fname'',''lname'',''email'',''address'',''city'',''state'',''zip'',''username'',''password'',''age'',''mobile'',''phone'']
