我正在構建允許發佈到django後端的端點。交易模型具有多對多關係頂部賬簿管理人，以及我的串行器在默認情況下已經低於PrimaryKeyRelatedField：使用PrimaryKeyRelatedField保存django-rest
Models.py
class Deal(models.Model):
book_runner = models.ManyToManyField(BookRunner, blank=True, null=True, related_name="deal_book_runner")
Serializers.py
class DealSerializer(serializers.ModelSerializer):
book_runner = PrimaryKeyRelatedField(allow_null=True, many=True, queryset=BookRunner.objects.all(), required=False)
equity = Equity.objects.create(**equity_data)
def create(self, validated_data):
deal = Deal.objects.create(**validated_data)
return deal
Views.py
class DealAdminViewSet(viewsets.ModelViewSet):
queryset = Deal.objects.all()
serializer_class = CreateDealSerializer
def create(self, request, format=None):
book_runner = request.data.get('book_runner', None) #array
打印驗證前的數據（validated_data）程序中斷：
{'book_runner': u'2'}
現在，當我發佈與主鍵= 2賬簿管理人的交易，我得到一個錯誤：
File "/usr/lib/python2.7/json/encoder.py", line 184, in default
raise TypeError(repr(o) + " is not JSON serializable")
TypeError: <property object at 0x7f1559578158> is not JSON serializable
我希望同時使用陣列和未來的主鍵的數字。謝謝你的幫助！
