Issues with Serializers and Querysets

[cancan101]

This code:

        serializer = ThingSerializer(data=things, many=True)
        serializer.is_valid(raise_exception=True)
        return Response(serializer.data, status=status.HTTP_200_OK)

yields:

{
    "non_field_errors": [
        "Expected a list of items but got type \"QuerySet\"."
    ]
}

whereas changing the is_valid call to:

        serializer.is_valid(raise_exception=False)

works without a problem. Removing that entire line yields:

When a serializer is passed a data keyword argument you must call .is_valid() before attempting to access the serialized .data representation.
You should either call .is_valid() first, or access .initial_data instead.

Again this is a usage question. Please use the mailing list so we can keep the issue tracker for issues.

(Nonetheless: things is a QuerySet, so you're trying to serialise objects from the ORM, in which can you pass them as the first positional argument, rather than via the data kwarg.)
