Some guidance on json structure to a django DRF serializer

Question

I have a model structure like this:

model:
    server_name: str
    description: str
    owner: str

but the application sending data to my app use a json format I am not sure on how to create a serializer for. For multiple entries it looks like this

{
    "server1": {
        "description": "desc of server 1",
        "owner": "service name"    },
    "server2": {
        "description": "desc of server 2",
        "owner": "service name"
    }
}

but I am not sure on how to get it into something matching my model. This is the structure I would like it to have in the serializer

[
    {
        "server_name": "server1", 
        "description": "desc of server 1",
        "owner": "service name"
    },
    {
        "server_name": "server2", 
        "description": "desc of server 2",
        "owner": "service name"
    }
]

Any suggestions on this one?

with the help of the Documentation ListField, you can try this:

serializers.py:

from rest_framework import serializers

class ServerSerializer(serializers.Serializer):
    jsonData = serializers.ListField(
        child=serializers.JSONField()
    )

views.py:

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from .serializers import ServerSerializer

class ServerAPIView(APIView):
    serializer_class = ServerSerializer

    def post(self, request):
        data = request.data
        serializer = self.serializer_class(data=data)
        serializer.is_valid(raise_exception=True)

        # Get data
        json_data = data.get('jsonData')
        for item in json_data:
            server_name = item['server_name']
            description = item['description']
            owner = item['owner']
            YourModel.objects.get_or_create(
                    server_name=server_name, description=description, 
            owner=owner)
        result = YourModel.objects.all()
        serializer = self.serializer_class(result, many=True)

        return Response(serializer.data, status=status.HTTP_201_CREATED)
