Filtering the specific data for response in DRF

Question

I have following response data

[
{
    "id": 7,
    "name": "Default Group",
    "permissions": [
        22,
        24
    ]
},
{
    "id": 10,
    "name": "Another Group",
    "permissions": [
        1,
        2,
        22,
        24
    ]
},
{
    "id": 11,
    "name": "New Group",
    "permissions": [
        10,
        11,
        12,
        5,
        6,
        7,
        8
    ]
}]

But I want to remove the dictionary whose id = 10 from the response data ,how can I do that ?

I have following lines of code..

class GetUserGroupList(APIView):


def post(self, request, *args, **kwargs):

    groups = Group.objects.all()
    serializer = GroupSerializer(groups, many=True)

    return Response(serializer.data)

In serializers.py

class GroupSerializer(serializers.ModelSerializer):

class Meta:
    model = Group
    fields = ('id', 'name', 'permissions',)

Any help would be appreciated !!

Answer 1

If you want to include/exclude certain items from the response, you can filter queryset for achieving that. I recommend you to use generic API views like below:

from rest_framework import generics


class UserGroupListView(generics.ListAPIView):
    serializer_class = GroupSerializer
    queryset = Group.objects.exclude(permissions=10)

Answer 2

Not sure about the seializers.py stuff you mentioned but I wrote this one-liner than gets the job done:

response = [i for i in response if i['id'] != 10]

Basically, it iterates through the list response, creating a new list that is also called response, except the new list does not contain any dict with an id of 10

Answer 3

Actually I had earlier solution as below but ,there are other better ways in answers as well

 groups = Group.objects.all()
    serializer = GroupSerializer(groups, many=True)

    data_is = list(serializer.data)
    print(type(data_is))
    for item in data_is[:]:
        if item['id'] == 10:
            data_is.remove(item)
    print(data_is)

    return Response(data_is)
