Django的Tastypie - OneToOne關係POST不起作用

我不斷收到這個響應誤差不管我怎麼努力。該方法似乎完美適用於ManyToOne關係，但在OneToOne中失敗。請幫助，如果有人遇到並解決過這樣的：Django的Tastypie - OneToOne關係POST不起作用

400 BAD REQUEST 
{"error": "The 'order' field has no data and doesn't allow a default or null value."}

調試試驗：

試圖在物流詳情增加一個獨立的主鍵「ID」，因爲我懷疑tastypie可能會失敗，因爲它在創建相關字段之前無法生成Order ID。
刪除的訂單字段中DeliveryDetails API，並試圖引用只在訂單資源的相關領域。

請求：

curl -X "POST" "http://localhost:5000/core/api/v1/order/" \ 
    -H "Content-Type: application/json" \ 
    -d "{\"source\":\"W\",\"delivery_detail\":{\"email\":\"[email protected]\"}}"

型號：

class Order(models.Model): 
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) 
    created_at = models.DateTimeField(
     verbose_name='created at', 
     auto_now_add=True 
    ) 
    updated_at = models.DateTimeField(
     verbose_name='updated at', 
     auto_now=True 
    ) 
    SOURCE_TYPES = (
     ('I', 'iOS'), 
     ('A', 'Android'), 
     ('W', 'Web'), 
     ('N', 'Not Applicable') 
    ) 
    source = models.CharField(
     verbose_name='order source', 
     max_length=1, 
     choices=SOURCE_TYPES, 
     default='N' 
    ) 
class DeliveryDetail(models.Model): 
    order = models.OneToOneField(
     to=Order, 
     primary_key=True 
    ) 
    email = models.EmailField(
     verbose_name='email address', 
     max_length=255, 
     blank=True, 
     null=True 
    )

API：

class OrderResource(ModelResource): 
    delivery_detail = fields.ToOneField(
     to='core.api.v1_order.DeliveryDetailResource', 
     attribute='deliverydetail', 
     related_name='order', 
     help_text='Delivery details', 
     full=True 
    ) 

    class Meta: 
     queryset = Order.objects.all() 
     resource_name = 'order' 
class DeliveryDetailResource(ModelResource): 
    order = fields.ToOneField(
     to=OrderResource, 
     attribute='order' 
    ) 

    class Meta: 
     queryset = DeliveryDetail.objects.all() 
     resource_name = 'delivery_detail'

OneToOne字段不允許空值。所以當時，你想創建你的交貨，訂單尚未創建，所以訂單爲空。或者第一和然後分裂爲訂單請求送貨，或設置ToOneField屬性null=True
