django non rel and google app engine: remote api issue

Question

I am deploying a django-nonrel app on Google App Engine. The app deploys alright but I can't login to the remote shell.

This is my app.yaml file:

application: masnun
version: 1
runtime: python
api_version: 1

builtins:
- remote_api: on

inbound_services:
- warmup

handlers:
- url: /_ah/queue/deferred
  script: djangoappengine/deferred/handler.py
  login: admin

- url: /media/admin
  static_dir: django/contrib/admin/media
  expiration: '0'

- url: /.*
  script: djangoappengine/main/main.py

But I am getting an error:

urllib2.URLError: <urlopen error HTTP Error 500: Internal Server Error
Couldn't reach remote_api handler at https://masnun.appspot.com/_ah/remote_api(/.*)?.
Make sure you've deployed your project and installed a remote_api handler in app.yaml.>

Please help me out!

Update: When using Python2.5, getting this error:

DEBUG:google.appengine.tools.appengine_rpc:Got http error, this is try #3
DEBUG:google.appengine.tools.appengine_rpc:Sending HTTPS request:

Answer 1

The problem is with

GET /_ah/remote_api(/.*)? HTTPS/1.1

If you notice, the URL contains invalid characters "(/.*)?" towards the end.

Assuming you are using django-nonrel, it is an easy fix. Open the file

djangoappengine/db/base.py

and change the line

self.remote_api_path = handler.url

to

self.remote_api_path = handler.url.split('(')[0] # remove '(/.*)' introduced in newer GAE

and that should take care of ensuring the URL is correct.

Answer 2

Add this on app.yaml section handlers, first item:

handlers:
- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

and deploy again.

Answer 3

You can connect to the remote shell using

python manage.py remote shell

and only if you created your App Engine app with Google Accounts Authentication. But remote_api requires a deployed app and since your

python manage.py deploy

fails, the above error is normal.

What error do you get when you try to deploy?
