py4web GAE db datastore connection

[Jacinto Parga]

Hi, 

I have deployed an app in GAE and works fine with these  db settings in settings.py:

# db settings

APP_FOLDER = os.path.dirname(__file__)

APP_NAME = os.path.split(APP_FOLDER)[-1]

# DB_FOLDER:    Sets the place where migration files will be created

#               and is the store location for SQLite databases

DB_FOLDER = os.path.join(APP_FOLDER, "databases")

DB_URI = "sqlite://storage.db"

DB_POOL_SIZE = 1

But it's not connected to google:datastore. If I just change:

# db settings

APP_FOLDER = os.path.dirname(__file__)

APP_NAME = os.path.split(APP_FOLDER)[-1]

# DB_FOLDER:    Sets the place where migration files will be created

#               and is the store location for SQLite databases

DB_FOLDER = os.path.join(APP_FOLDER, "databases")

DB_URI = "google:datastore"

DB_POOL_SIZE = 1

It returns a not found error.

How can I configure py4web db connection to datastore?

Thanks
