【问题描述】：

我正在尝试将初始数据导入我的 Django 应用程序。我有几张表，但我想一一导入。

我决定从最简单的表格开始：

class ClientRun(models.Model):
    start_time = models.BigIntegerField()
    end_time = models.BigIntegerField()
    ip = models.GenericIPAddressField()
    country = models.CharField(max_length=255)

    def __unicode__(self):
        return str(self.start_time) + " " + str(self.end_time)

我手动创建了一个夹具文件：

[
  {
    "model": "georoute.clientrun",
    "pk": 1,
    "fields": {
        "ip": "0.0.0.0",
        "start_time": 0,
        "end_time": 0,
        "country": "ZZ"
    }
  },
]

当我跑步时

python manage.py loaddata shengy_clientrun.json

它返回：

我仔细检查了 JSON 格式，现在数据库是空的。我使用 MySQL 作为后端数据库。

【问题讨论】：

您的灯具不是有效的 JSON。与 Python 不同，JSON 不能有尾随逗号。
@dgel 成功了:) 谢谢！
