Django Nonrel and Google App Engine

The guys behind appengine patch have a new project using the Django nonrel project to run on App Engine.

Clone the appropriate projects from bitbucket :

$ hg clone https://[Bitbucket User Name]@bitbucket.org/wkornewald/django-nonrel/
$ hg clone https://[Bitbucket User Name]@bitbucket.org/wkornewald/djangoappengine/
$ hg clone https://[Bitbucket User Name]@bitbucket.org/wkornewald/django-testapp/

The instructions say next, "Now you should be able to create a new app in the testapp folder and use native Django models on App Engine. Try it!"

dignan@dignan-laptop:~/workspace/django-nonrel/django-testapp$ python manage.py runserver
Traceback (most recent call last):
File "manage.py", line 4, in <module>
from djangoappengine.boot import setup_env
ImportError: No module named djangoappengine.boot

Hmmm.

The documentation calls for two symlinks :

django-testapp/common-apps/djangoappengine -> ../../djangoappengine

django-testapp/common-apps/djangoappengine -> ../../django-nonrel/django

I created them and tried again.

The Google App Engine SDK could not be found!
Make sure it's accessible via your PATH environment.

So I added the it to my path and tried again. Same result.

I found the following on the appengine-patch website:

"you can also put the SDK into any folder that is in the system's PATH environment variable as long as it's called "google_appengine" (this works with any OS)"

My sdk was in "google_appengine_1.3.0". I created a symlink, "google_appengine" and tried again.

At least it started! I cd'd into the app's directory and ran:

python manage.py runserver

It started up. I got the default "It worked!" page.
