model

I have a model with a JSON field or a link to a CouchDB document. I can currently access the dynamic informaction in a way such as:

genericdocument.objects.get(pk=1) == genericdocument.json_field['sample subfield'] instead I would like genericdocument.sample_subfield

to maintain compatibility with all the apps the project currently shares.
