Я нашел ответ, который звучит примерно так (да, я знаю, что это глупо!)

Я думаю, что мне нужно переписать функцию is_valid в форме, чтобы убедиться, что в одном из полей есть данные, прежде чем делать что-то вроде super.is_valid() (в противном случае возвращается true, поэтому я не выдаю ошибку для пустого form), а также функцию pre-save в форме, которая принимает объекты user и client и помещает их в поля и проверяет наличие номера телефона перед сохранением.
- Перезаписать
is_valid(), чтобы пустые значения могли пройти через
- Создайте
pre-save() для загрузки в User и Client в модель и отмените, если можете, если нет значения для number
ЭТО СУМАСШЕДШЕЕ !!!
Единственное, о чем я могу думать, это сделать phone_type и number в ClientPhone модели blank=True, null=True, чтобы у меня могли быть дополнительные поля телефона
ЭТО БЕЗУМНО КАК ХОРОШО !!!
Почему я должен нарушать целостность моей модели, чтобы иметь поле опции в одной из моих форм ???
EDIT:
view.py оказался чище, когда я сделал следующее для файла forms.py:
class ClientDetailsForm(ModelForm):
class Meta:
model = ClientDetails
exclude = ('client', 'created', 'created_by')
def CustomSave(self,c,u):
t = self.save(commit=False)
t.client = c
t.created_by = u
t.first_name = self.cleaned_data['first_name'].capitalize()
t.middle_name = self.cleaned_data['first_name'].capitalize()
t.last_name = self.cleaned_data['first_name'].capitalize()
t.save()
class ClientAddressForm(ModelForm):
class Meta:
model = ClientAddress
exclude = ('client', 'created', 'created_by')
def CustomSave(self,c,u):
t = self.save(commit=False)
t.client = c
t.created_by = u
t.address_1 = self.cleaned_data['address_1'].capitalize()
t.address_2 = self.cleaned_data['address_2'].capitalize()
t.address_3 = self.cleaned_data['address_3'].capitalize()
t.address_4 = self.cleaned_data['address_4'].capitalize()
t.post_code = self.cleaned_data['post_code'].upper()
t.save()
class ClientPhoneForm(ModelForm):
number = UKPhoneNumberField()
class Meta:

def CustomSave(self,c,u):
t = self.save(commit=False)
t.client = c
t.created_by = u
t.save()
class ClientOtherPhoneForm(ModelForm):
number = UKPhoneNumberField(required=False)
class Meta:
model = ClientPhone
exclude = ('client', 'created', 'created_by')
def CustomSave(self,c,u):

t.save()
