What you written is made as self._data[key] = val. If you're not
experienced with python, do not use anything starting with __.

To update document from dict, (remembering that document is much like
a dict), use update method:
self.update({'new key': "new value"})

couchdb-python already provides you with JSON decoding so you see
couch docs as python dicts.

To get document from database by id, you use

doc = db['id']

that's covered in couchdb-python documentation. Which is in

P.S. and first of all, this is CouchDB mailing list. Couchdb-python
