Thanks for this nice feature.
How can I make it run with ./dev_appserver.py (development for gae)?
So far, I have this:
File "......../workspace/google_appengine/src/google/appengine/api/
datastore.py", line 2172, in _GetCompleteKeyOrError
raise datastore_errors.BadKeyError('Key %r is not complete.' %
key)
BadKeyError: Key datastore_types.Key.from_path(u'target', 0L,
_app_id_namespace=u'web2py') is not complete.
Regards,
Edouard
