Question

我正在使用Django和Postgre开发应用程序。

基本上，我在我的应用上创建了新模型。

from django.db import models
from manager.models.state import State
from django.contrib.auth.models import User

class Address (models.Model):
 address_id = models.AutoField(primary_key=True)
 address_name = models.CharField(max_length=500)
 address_city = models.CharField(max_length=250)
 address_phone = models.IntegerField()
 address_postcode = models.CharField(max_length=10, default = 0)
 state =  models.ForeignKey(State, null=True, blank=True, default = None)
 user = models.ForeignKey(User,  null=True, blank=True, default = None)

def __unicode__(self):
    return self.address_id

@classmethod
def get_list(cls):
    return list(cls.objects.values())

之后我运行makemigrations并迁移命令行。所有模型都是在数据库中正常创建的。

我成功加载了其他json文件（fixture）的数据。当我试图在地址表上loaddata address.json时，我收到了这个错误。

错误讯息：

django.db.utils.DataError: Problem installing fixture '/Users/eeldwin/Documents/Django/fbt/manager/fixtures/address.json': Could not load manager.Address(pk=1): integer out of range

这是我的灯具

[{
"model": "manager.address",
"pk": 1,
"fields": {
  "address_id": "1",
  "address_name": "Jalan Muara Mas Timur 242",
  "address_city": "Semarang",
  "address_phone": "087832270893",
  "address_postcode": "3122",
  "state": "1"
}}]

但是，当我手动将数据插入数据库时，它将完美运行。有什么想法在这里发生了什么？谢谢。

Answer 1

您将address_phone存储为IntegerField。其最大值为2147483647（https://docs.djangoproject.com/en/1.7/ref/models/fields/#integerfield）。

但是在您的灯具中，您尝试将087832270893添加为address_phone，这就是您收到integer out of range错误的原因。
