当我们使用 django rest 框架发出 post 请求时，如何返回主键作为响应? [英] How to return primary key as a response when ever we make a post request using django rest framework?

问题描述

我有 django 模型和它的视图定义为:

I have django model and a view for it define as:

class ItemViewSet(viewsets.ModelViewSet):

queryset = Item.objects.all()
serializer_class = ItemSerializer  

我应该怎么做才能返回主键作为响应?这是我的 Json 在发出帖子请求后的样子:

what should i do to return a primary key as response ? This is how my Json looks after making post request:

{
        "id": 4,
        "UID": "465666700",
        "name": "rohit ",
        "gender": "MALE",
        "yob": "1996"
    }

我的回答应该是:4 即主键`class ItemSerializer(serializers.ModelSerializer):

and my response should be: 4 i.e primary key `class ItemSerializer(serializers.ModelSerializer):

    class Meta:
    model = Item
    fields = ('id', 'name', 'mrp','imageid', 'company', 'edible','discount','seller_uid','seller_pk')`

感谢帮助.

推荐答案

为您的 Item 模型声明一个 ModelSerializer.将 fields 属性设置为 ['id'] 就可以了！

Declare a ModelSerializer for your Item model. Set the fields attribute to ['id'] and that should work!

class ItemSerializer(serializers.ModelSerializer):
    model = Item
    fields = ['id']
