如何通过Django REST Framwork序列化列表

Question

I have a function which base on different Pandas processes it result a list ( [6, 6, 6] ). My question is how can I serialize it with Django REST Framwork . I tried to implement the documentation bit I just get different errors. Unfortunately I am newby in rest, and this is the fist time when I build Django with API endpoint.

Here is my attempt:

[serializers.py]

class TestSerializer(serializers.ListField):
    child = serializers.IntegerField()

[views.py]

class TestListCreate(generics.ListCreateAPIView):
    queryset = Test().test_list[0] # This results the list --> [6, 6, 6]
    serializer_class = TestSerializer

Answer 1

Since there is no Model , you don't have to use queryset attribute or ListCreateAPIView at all. You can use APIView class as

from rest_framework.views import APIView
from rest_framework.response import Response


class MyTestView(APIView):
    def get(self, request, *args, **kwargs):
        my_list_data = Test().test_list[0]  # get the data
        serializer = TestSerializer(my_list_data)
        return Response(data=serializer.data)

and change your serializer as,

 class TestSerializer(serializers.ListSerializer):
    child = serializers.IntegerField()

Note : I don't think there is much difference between ListSerializer and ListField , but I would recommend ListSerializer anyway
