Answer 1

Podejrzewam klasę UserForm powinien być wzór formularza. Możesz zmienić pola, ale powinny one pochodzić z `ModelForm.

więc zmienić definicję formularz do

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 definiuje Fields w nawiasach kwadratowych takich dziedzinach = [ 'field 1', '2 Pole', ...]

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