扩大的Modelform不保存相干表-英雄云拓展知识分享

我已扩大了一个Modelform，但是相干模型没法正确保存到数据库。下面我只打电话 SupplyAddress() 而不是经过创建和保存它的实例 SupplyAddress.objects.create() 但是，如果我尝试这样做，那末还没有创建相干地址（和用户）来保存。解救用户的最好方法是甚么？ Address 和 SupplyAddress?

模型

class Address(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL)
house_name_number = models.CharField(max_length=255, verbose_name="house name or number")
street_name = models.CharField(max_length=255)
town_city = models.CharField(max_length=255)
county = models.CharField(max_length=255)
postcode = models.CharField(max_length=8)
time_stamp = models.DateField(auto_now=True)
class SupplyAddress(models.Model):
address = models.OneToOneField(Address)
region = models.ForeignKey(Region, null=True)
occupied = models.BooleanField()

forms.py

class SupplyAddressForm(forms.ModelForm):
occupied = forms.BooleanField()
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
data = self.cleaned_data
supply_address = models.SupplyAddress(
occupied=data['occupied'],
)
self.instance.supplyaddress = supply_address
return self.instance
class Meta:
model = Address
fields = ['house_name_number',
'street_name',
'town_city',
'county',
'same_address',
'move_in_date',
'postcode',
]

Views.py

.....
address = form.save(commit=False)
address.user = user
address.save()
