django - create 方法在序列化程序中引发关键错误

问题描述

我正在创建一个用于注册的 API。

序列化程序.py

class UserSignupSerializer(serializers.Serializer):


class Meta:
    model = User
    fields = ['username', 'first_name', 'last_name', 'email', 'role']
    extra_kwargs = {'password': {'write_only': True}}

def create(self, validate_data):

    user = User.objects.create(email=validate_data['email'], first_name=validate_data['first_name'],last_name=validate_data['last_name'], role='user', username=validate_data['username'])
    user.set_password(validate_data['password'])

    user.save()
    return user

视图.py

class UserSignupView(APIView):
    def post(self, request):
        serializer = UserSignupSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        else:
            return Response(status=status.HTTP_204_NO_CONTENT)

但这会给出关键错误“电子邮件”或我在此行中首先放置的任何内容：

user = User.objects.create(email=validate_data['email'], first_name=validate_data['first_name'],last_name=validate_data['last_name'], role='user', username=validate_data['username'])

编辑 错误

解决方案

我认为您应该使用serializers.Modelserializer而不是serializers.Serializer。
