Question

这是我的serializers.py：

class SysUserSerializer(serializers.ModelSerializer):
    pk = serializers.IntegerField(read_only=True)
    login_id = serializers.CharField(required=False)
    name = serializers.CharField(required=False)

    class Meta:
        model = SysUser
        fields = ('pk','login_id','name')

这是我的views.py：

class GetUserDetail(APIView):
    def get(self, request, format=None):
        sysuser = SysUser.objects.get(id=1)
        serializer = SysUserSerializer(sysuser)
        serializer.data['gender'] = 'male' # i don't think this line is working
        return Response(serializer.data, status=200)

但我得到了这样的答复：

{"pk": 1, "login_id": "john77", "name": "John"}

我想要这样的回复：

{"pk": 1, "login_id": "john77", "name": "John", "gender": "male"}

怎么做？是否有可能这样做？

这里的问题是serializer.data不是实例参数，而是返回它的property。因此，您可以通过将serializer.data分配给变量来解决此问题。

class GetUserDetail(APIView):
    def get(self, request, format=None):
        sysuser = SysUser.objects.get(id=1)
        serializer = SysUserSerializer(sysuser)
        data = serializer.data
        data['gender'] = 'male'
        return Response(data, status=200)

您也可以在validate序列化方法

中将数据分配给serializer.data

Django rest框架将dict添加到序列化程序
