python - 'int' 对象没有属性 'replace' 在 Django 中加载初始数据

Question

我正在尝试熟悉如何使用 loaddata 将初始数据加载到模型中。所以我的 json 看起来像这样:

[
  {
    "model": "locations.location",
    "pk": 1,
    "fields": {
      "name": "Cafe"
    }
  }
]

我的模型.py:

class Location(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4)
    create_date = models.DateTimeField('date added', auto_now_add=True)
    modify_date = models.DateTimeField('date modified', default=timezone.now)
    name = models.CharField(max_length=200)

然后当我执行 python manage.py loaddata mydata 时，我得到了

django.core.serializers.base.DeserializationError: Problem installing fixture '/path/to/locations/fixtures/mydata.json': 'int' object has no attribute 'replace'

这是什么意思？我还尝试在 models.py

中更改它

def __unicode__(self):
    return self.name

到

def __unicode__(self):
    return self.name.get_full_name() 

但是没用。这个int对象是什么？

由于所有的评论，这才有效:

[
  {
    "model": "locations.location",
    "fields": {
        "id":"a3184190-0b97-4c56-8aac-eeee8875aaa2",
        "name": "Cafe"
    }
  }
