「詮釋」對象有沒有屬性「取代」在Django

加載初始數據，我試圖讓熟悉加載初始數據與loaddata的典範。所以，我的JSON看起來像這樣：「詮釋」對象有沒有屬性「取代」在Django

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

我model.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)

，然後當我做python manage.py loaddata mydata我得到

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

這是什麼意思？我也試過在models.py

def __unicode__(self): 
    return self.name

改變這

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

，但沒有奏效。這個int對象是什麼？

那是你的所有mydata.json文件？ – Gocht

是的，我想嘗試一下，如果它工作，所以我想一個字段添加到我的模型 – Tom

顯示模型，請。 – Gocht
