【问题描述】：

我想发布请求 django rest 但是这个错误。我有两个序列化程序。我想发布一个不通过 id 的完整数据请求

Exception Value:    
Field 'id' expected a number but got OrderedDict([('title', 'id:2 Смартфон Samsung Galaxy Note 20 Ultra 256GB Black'), ('price', 2019)]).  



 class ShopSerializer(serializers.ModelSerializer):
        img1 = serializers.SerializerMethodField('get_image_url')
        img2 = serializers.SerializerMethodField('get_image_url')
        img3 = serializers.SerializerMethodField('get_image_url')
        img4 = serializers.SerializerMethodField('get_image_url')
        img5 = serializers.SerializerMethodField('get_image_url')
        img6 = serializers.SerializerMethodField('get_image_url')
        class Meta:
            model = smartphone
            fields = ("id", "img1", "img2", "img3", "img4", "img5", "img6","title","price","slug")
        def get_image_url(self, obj):
            return obj.image.url
        
        
  class OrderCreateSerializer(serializers.ModelSerializer):
        smartphone=ShopSerializer(many=True)
        class Meta:
            model = order
            fields = '__all__'
    
        def create(self, validated_data):
            
            smartphone = validated_data.pop('smartphone')
            question = order.objects.create(**validated_data)
            question.smartphone.set(smartphone)
            return question

class OrderCreateView(generics.CreateAPIView):
    queryset = order.objects.all()
    serializer_class = OrderCreateSerializer

【问题讨论】：

请添加您的views.py。你跑python manage.py makemigrations 和python manage.py migrate了吗？
@MichaelH 添加了视图
观看次数看起来不错。您在 github 上是否有示例项目，或者您也可以提供模型文件吗？

请尝试以下发帖请求：

        "price": 2019,

        "slug": "id2-samsung-galaxy-note-20-ultra-256gb-black",
        "title": "id:2 Смартфон Samsung Galaxy Note 20 Ultra 256GB Black"
    }],
    "orderCustomer": 6,
    "orderAddress": 5
}

更新：

还要确保此行按预期工作 question.smartphone.set(smartphone).

smartphones = validated_data.pop('smartphone')
smartphone_models = []
for sm in smartphones:
    print("value of sm is: {}".format(sm))
    print("type of sm is: {}".format(type(sm)))
    new_smartphone = smartphone.objects.create(sm)
    new_smartphone.save()
    smartphone_models.append(new_smartphone)
question = order.objects.create(**validated_data)
print(smartphone_models)
question.smartphone.set(smartphone_models)

【讨论】：

'collections.OrderedDict' object has no attribute 'objects' 这样的错误就出来了
@AsylkhanMustafa 对不起我的错。我更新了答案
请注意 post 请求中添加的花括号
create () 接受 1 个位置参数，但给定了 2 个错误
如果在此行之前添加print(sm)，输出是什么
