Change serializers.Field to serializers.ReadOnlyField for 3.x compatibility

Using this code snippet as-is on DRF 3.0.1 results in a NotImplementedError
being raised for to_representation due to 3.0's changed behavior with
serializers.Field. The code snippet should be updated to use
serializers.ReadOnlyField instead.

Better errors when serializer has incorrectly named field.

Improve error checking for nested writes.
