根據我在下面放置的給定數據對象。我想問如何在 django 中批量插入或創建多個數據。我在下面提供了包括我的序列化程序和 python 代碼。我想從下面的數據對象創建/插入每個密碼。不用擔心其他數據。我也想用序列化器來做。我確實嘗試遍歷 data: 中的 each_employee_data 的數據。我的代碼有任何問題。謝謝你。代碼def post(self, request, format=None): data = request.data print("Data::" , data) for each_employee_data in data: each_employee_data["verification_code"] = verification_code(self) password = hashers.make_password(each_employee_data["password"]) each_employee_data["password"] = password print("each_employee_data", each_employee_data) user_serializer = UserSerializer(data= each_employee_data) if user_serializer.is_valid(raise_exception=True): if not each_employee_data["is_applicant"]:#company company_serializer = CompanySerializer(data=data) if company_serializer.is_valid(raise_exception=True): user_ins = user_serializer.save(password=password) company_serializer.save(user=user_ins) else: applicant_serializer = ApplicantSerializer(data=each_employee_data) if applicant_serializer.is_valid(raise_exception=True): user_ins = user_serializer.save(password=password) applicant_serializer.save(user=user_ins) send_confirmation.delay(data) if not user_ins.is_applicant: send_business_confirmation.delay(data)

當一個序列化器被實例化并傳遞了 many=True 時，一個 ListSerializer 實例將被創建。然后序列化器類成為父 ListSerializer 的子級。ListSerializer 類提供了一次序列化和驗證多個對象的行為。
當您可能想要自定義 ListSerializer 行為時，有一些用例。在您的情況下，您希望 ListSerializer 進行批量更新。您需要定義一個新的自定義 ListSerializer
class CustomListSerializer(serializers.ListSerializer):
...
def create(self, validated_data):
...
class CustomSerializer(serializers.Serializer):
...
class Meta:
list_serializer_class = CustomListSerializer
在你的情況下，它應該是
class UserListSerializer(serializers.ListSerializer):
...
def create(self, validated_data):
user = [User(**item) for item in validated_data]
return User.objects.bulk_create(User)
class UserSerializer(serializers.Serializer):
...
class Meta:
list_serializer_class = UserListSerializer
