如何通过Django-Rest-Framework中的数据属性重构数据？

Question

我有一个磁盘序列化程序，下面是我的磁盘序列化程序：

class DiskSerializer(ModelSerializer):

    diskessencetype_name = serializers.ReadOnlyField(source='diskEssenceType.name')
    diskostype_name = serializers.ReadOnlyField(source='diskOsType.name')
    class Meta:
        model = Disk
        fields = [
            "id",
            "price",
            "diskessencetype_name",
            "diskostype_name",
        ]

该views.py是在下面：

class DiskListAPIView(ListAPIView):
    serializer_class = DiskSerializer
    permission_classes = []
    queryset = Disk.objects.all()

然后生成如下所示的数据：

[
    {
        "id": 4,
        "price": "5.00",
        "diskessencetype_name": "ssd",
        "diskostype_name": "系统盘"
    },
    {
        "id": 5,
        "price": "6.00",
        "diskessencetype_name": "sas",
        "diskostype_name": "系统盘"
    },
    {
        "id": 6,
        "price": "5.00",
        "diskessencetype_name": "sas",
        "diskostype_name": "数据盘"
    },
    {
        "id": 7,
        "price": "6.00",
        "diskessencetype_name": "sas",
        "diskostype_name": "系统盘"
    },
    {
        "id": 8,
        "price": "6.00",
        "diskessencetype_name": "sas",
        "diskostype_name": "系统盘"
    },
  .....
  ]

但是我想搜索和约束以下数据：

{
    "系统盘":[{"id":5, "diskessencetype_name":"sas", "price":5.00},.....]
    "数据盘":[{"id":7, "diskessencetype_name":"ssd", "price":7.00},.....]
}

您会看到，它们是通过实例的属性（ diskostype_name ）进行重组的，是否有内置方法来实现它？

我该如何重建它们？

views.py

class Postlar(ListAPIView):
    permission_classes = []
    queryset = Disk.objects.all()
    serializer_class = DiskSerializer

    def list(self, request, *args, **kwargs):
        result = {}
        SerializerClass = self.get_serializer_class()
        for u in ["系统盘", "数据盘"]:
            serializer = SerializerClass(Disk.objects.filter(diskOsType__name=u), many=True)
            result[u] = serializer.data

        return Response(result)
