Return list of objects as dictionary with keys as the objects id with django rest framerwork

Question

Currently, I have a ListAPIView that returns a list of object dictionaries:

[
  { id: 1, ...},
  { id: 2, ...},
  ...
]

I would like to change

I think you can implement the to_representation function in your Serializer.

class MySerializer(serializers.Serializer):
    id = serializers.ReadOnlyField()
    field1 = serializers.ReadOnlyField()
    field2 = serializers.ReadOnlyField()

    def to_representation(self, data):
        res = super(MySerializer, self).to_representation(data)
        return {res['id']: res}
        # or you can fetch the id by data directly
        # return {str(data.id): res}
