Is it possible to run dev_appserver.py with the remote datastore?

Question

I\'m developing a web app with Google\'s AppEngine. I\'d like to iterate on the code locally using dev_appserver.py. But it\'s hard to do this without all the d

Yeah, it is possible.

First, turn on remote-api in app.yaml and deploy the application on production.

builtins:
- remote_api: on

Then, for example in appengine_config.py:

import os
from google.appengine.ext.remote_api import remote_api_stub
from google.appengine.datastore.entity_pb import Reference

remote_api_stub.ConfigureRemoteApi(app_id=None, path='/_ah/remote_api',
                                   auth_func=lambda: ('email', 'password'),
                                   servername='appid.appspot.com')

if os.environ['SERVER_SOFTWARE'].startswith('Development'):
  Reference.app = lambda *args: os.environ['APPLICATION_ID'].replace('dev~', 's~')

If you have old application ID you may need to edit .replace('dev'...) part.
