FieldDoesNotExist上承載夾具

我試圖加載夾具稱爲initial_data.json：FieldDoesNotExist上承載夾具

夾具的問題在哪裏？

當問及將問題解決爲最基本的要素很重要時。「[mcve]」表示我們需要最小的代碼和輸入數據來複制問題。除此之外的任何事情都會浪費太空和我們的時間，迫使我們通過毫無價值的信息進行溝通，這會導致對您的答案更慢，所以幫助我們幫助您。 –

在此頁面：https://docs.djangoproject.com/en/1.8/ref/contrib/contenttypes/#django.contrib.contenttypes.models.ContentType

「改變在Django 1.8：的Django 1.8之前，name屬性是對的ContentType模型一個真正的領域。」 - 意味着從1.8開始它不是一個真正的領域。你使用1.8嗎？如果您從ContentType設備中刪除名稱，它是否有效？

從ContentType中刪除名稱。謝謝梅根！ –

這是因爲ContentType.name是一個屬性，而不是一個Field。

從ContentType模型定義的摘錄：

class ContentType(models.Model): 
    app_label = models.CharField(max_length=100) 
    model = models.CharField(_('python model class name'), max_length=100) 
    objects = ContentTypeManager() 

    # ... 

    @property 
    def name(self): 
    # ...

在此模型中定義的域只有app_label和model。這意味着代碼序列化你的對象還包括了財產，其價值時，反序列化不能設置。

您可以嘗試從序列化數據中刪除任何不是模型Field（在您的情況下它只是name）。
