Cool NetBeans Plugin

Last week at AJUG's Devnexus conference Venkat Subramanium made an interesting point about IDEs.

He asked how many of the people in attendance used Eclipse. Unsurprisingly almost everyone raised a hand.

Then he asked how many of us would use it if it cost $500. Almost all of the hands dropped, including mine.

I downloaded NetBeans and IntelliJ.

I had used NetBeans for a while before. One thing I liked was its themes. I like light text on a dark background.

I found this theme, Aloha, and installed it. Pretty nice.

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

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.
