如何重新构造json对象django rest框架？

这是我的

json

来自

Django

{
    id:"123"
    latitude: "37.5111",
    longitude: "126.9743"
}

想要输出如下：

"123": {
     latitude: "37.5111",
     longitude: "126.9743"
}

序列化程序.py

class SearchSerializer(ModelSerializer):

    class Meta:
        model = IpGeo
        fields = [
            # 'id',
            # 'metadata',
            'latitude',
            'longitude'
        ]

class Search(ListAPIView):

    queryset = IpGeo.objects.all()
    serializer_class = SearchSerializer

视图.py

class SearchSerializer(ModelSerializer):

    class Meta:
        model = IpGeo
        fields = [
            # 'id',
            # 'metadata',
            'latitude',
            'longitude'
        ]

class Search(ListAPIView):

    queryset = IpGeo.objects.all()
    serializer_class = SearchSerializer

序列化程序.py

从rest_框架导入序列化程序

class SearchSerializer(ModelSerializer):

    custom_field = serializers.SerializerMethodField()


    class Meta:
        model = IpGeo
        fields = [
         'custom,'

        ]
   def get_custom_field(self):
      d = {}
      d[str(self.id)] = dict(latitude=self.latitude,longitude=self.longitude)
      return d
