Answer 1

ho il sospetto classe UserForm dovrebbe essere modello di formulario. Potresti voler cambiare campo, ma dovrebbe essere derivato da `ModelForm.

Così cambiano definizione modulo per

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 Definisce campi tra parentesi quadre come i campi = [ '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']
