根據(jù)我在下面放置的給定數(shù)據(jù)對(duì)象。我想問如何在 django 中批量插入或創(chuàng)建多個(gè)數(shù)據(jù)。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(shù)據(jù)對(duì)象創(chuàng)建/插入每個(gè)密碼。不用擔(dān)心其他數(shù)據(jù)。我也想用序列化器來做。我確實(shí)嘗試遍歷 data: 中的 each_employee_data 的數(shù)據(jù)。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(dāng)一個(gè)序列化器被實(shí)例化并傳遞了 many=True 時(shí)，一個(gè) ListSerializer 實(shí)例將被創(chuàng)建。然后序列化器類成為父 ListSerializer 的子級(jí)。ListSerializer 類提供了一次序列化和驗(yàn)證多個(gè)對(duì)象的行為。
當(dāng)您可能想要自定義 ListSerializer 行為時(shí)，有一些用例。在您的情況下，您希望 ListSerializer 進(jìn)行批量更新。您需要定義一個(gè)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(yīng)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
