在以下模型上使用Django的update_or_create方法时遇到问题。我收到此错误：
ValueError：以10为底的int（）无效文字：''
错误似乎总是抛出在update_or_create的最后一行，因为当我在语句中添加verified=False（默认值为False）时，该错误可以追溯到该行verified=False，而不是下面显示的行。
我的模特：
class Addresses(models.Model):
customer = models.ForeignKey('Customers', on_delete=models.CASCADE)
address_name = models.CharField(max_length=45)
company = models.CharField(max_length=45)
street1 = models.CharField(max_length=60)
street2 = models.CharField(max_length=30, blank=True, null=True)
street3 = models.CharField(max_length=30, blank=True, null=True)
city = models.CharField(max_length=45)
state = models.CharField(max_length=45)
zip = models.IntegerField()
country = models.CharField(default='US', max_length=45)
phone = models.IntegerField(blank=True, null=True)
residential = models.BooleanField(default=True)
verified = models.BooleanField(default=False)
class Customers(models.Model):
customer_name = models.CharField(max_length=75)
email = models.CharField(max_length=60, blank=True, null=True)
phone = models.IntegerField(blank=True, null=True)
ss_customer_id = models.IntegerField(blank=True, null=True, unique=True)
功能：
def addAddress(self, address, customer_id):
if address['name'] is not None and address['street1'] is not None and address['city'] is not None:
if address['state'] is not None and address['postalCode'] is not None:
address, created = Addresses.objects.update_or_create(
address_name=address['name'],
company=address['company'],
street1=address['street1'],
street2=address['street2'],
street3=address['street3'],
city=address['city'],
state=address['state'],
country=address['country'],
phone=address['phone'],
customer=customer_id #error thrown here
)
address.save()
return address
return False
数据：
address = {
'name': 'Johnny Appleseed',
'company': 'Apple Inc',
'street1': '456 Street',
'street2': 'APT 12',
'street3': None,
'city': 'City',
'state': 'LA',
'postalCode': '90000',
'country': 'US',
'phone': '4444444444',
}
customer_id = 2 #this is a valid primaryKey
self.addAddress(address, customer_id)
这是完整的追溯：

我尝试了此操作，但仍然收到相同的错误：
def addAddress(self, address, customer_id):
...
customer = Customers.objects.get(pk=customer_id)
print(customer) #Customers object (2)
address, created = Addresses.objects.update_or_create(
...
customer=customer,
)
我在做什么错？任何建议，将不胜感激：）
答案 0 :(得分：1)
Address.customer是一个对象，而不仅仅是ID。为了填充它，您需要从数据库中检索它。因此：
Customer.objects.get(customer_id)
希望有帮助。

由于@ hd1，我得以弄清楚这一点。 Addresses.objects.update_or_create
我传递的是客户主键而不是客户对象（hd1的答案）
我没有为必填zip字段设置值
“电话号码”列的值超过了最大长度
由于某些原因，所有这些事情导致抛出了我的问题中的错误！
修复所有这些问题后，我不再出现错误。
