Django DRF创建用户

我正在尝试序列化

CreateUserSerializer（ModelSerializer）

我的代码如下。我的问题是，它只会创建

用户

，而不会创建

用户配置文件

型号.py

class UserProfile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    """
    Many other attributes like display_name, dob, hometown, etc
    """

class CreateUserProfileSerializer(ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username', 'email', 'password')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        user = User.objects.create(
                validated_data['username'],
                validated_data['email'],
                validated_data['password'])
        user.save()
        user_profile = UserProfile(user=user)
        user_profile.save()
        return user_profile

序列化程序.py

class UserProfile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    """
    Many other attributes like display_name, dob, hometown, etc
    """

class CreateUserProfileSerializer(ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username', 'email', 'password')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        user = User.objects.create(
                validated_data['username'],
                validated_data['email'],
                validated_data['password'])
        user.save()
        user_profile = UserProfile(user=user)
        user_profile.save()
        return user_profile

在我看来是这样的

api/views.py

class RegistrationAPI(GenericAPIView):
    serializer_class = CreateUserProfileSerializer

    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.save()
        return Response({
            "user": UserProfileSerializer(user, context=self.get_serializer_context()).data,

        })

如果你遵循代码，回复会给我一个提示

“RelatedManager没有属性'pk'”

更改您的

serializer.py

，如下所示

class CreateUserProfileSerializer(ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username', 'email', 'password')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        user = User.objects.create(**validated_data)
        UserProfile.objects.create(user=user)
        return user

您好，这不起作用。仍然只创建用户对象，但不创建UserProfile对象@杰林·彼得·乔治诺普，你错了。它将创建一个

User

实例，并将其分配/映射到新创建的

UserProfile

实例。检查您的

Django管理员

或

Django shell

，如果您想知道您是对的。它确实有效。我道歉。我忘了我在玩它，在api/views.py中修改了序列化程序。非常感谢。
