For object-like design document definition, see issue 186:
http://code.google.com/p/couchdb-python/issues/detail?id=186
and here we go:
class MyDDoc(Document):
@ViewFunction.map('foo')
def by_bar(doc):
for bar in doc['foo']:
yield bar, None
by_bar.reduce('_count') # use built-in reduce
@ShowFunction.define('foo')
def bar(doc, req):
return {'json': doc['foo']}
@ValidateDocUpdateFunction.define('foo')
def vdu(newdoc, olddoc, userctx, secobj):
assert 'foo' in newdoc, 'foo missed'
sync_docs(db, [MyDDoc]) # creates and stores _design/foo ddoc
But it will be useless without query server that support of all these functions.
