    user = models.OneToOneField(auth.models.User)
    mobile_number = models.CharField(max_length=64)
    office_number = models.CharField(max_length=64)

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'']
