Django Serializer: How to Sort Data in Descending Order

To sort serialized data in descending order, you can use the 'order_by' method of the queryset before serializing it. For example:

queryset = MyModel.objects.all().order_by('-created_at')
serializer = MyModelSerializer(queryset, many=True)
data = serializer.data

In this example, the queryset is sorted by the 'created_at' field in descending order (indicated by the '-' before the field name), and then serialized using the 'MyModelSerializer'. The resulting 'serializer.data' will contain the serialized data in descending order.
