Run GAE SDK for Python and Django on Ubuntu Maverick

First, I make the following structure in my project's directory:
~/projects/gae/ - directory for GAE's projects
~/projects/gae/google_appengine/ - downloaded GAE sources
~/projects/gae/google_appengine/test/ - test project using GAE

So, to run this test project as well as other further projects that use GAE

1. Download Google App Engine SDK for Python and unpack it to ~/projects/gae/.
   
2. Install python-2.5
   

   sudo add-apt-repository ppa:fkrull/deadsnakes
   sudo apt-get update
   sudo apt-get install python2.5
   

3. Install easy_install for Python 2.5
   

   cd /tmp
   wget http://pypi.python.org/packages/2.5/s/setuptools/setuptools-0.6c11-py2.5.egg
   sh setuptools-0.6c11-py2.5.egg
   

4. Install Django 1.1 for Python 2.5
   

   easy_install-2.5 django==1.1.1
   

5. Put into ~/projects/gae/google_appengine/test file
   

   echo "#!/bin/bash
   
   python2.5 ../google_appengine/dev_appserver.py ./" > run
   chmod a+x run
   

When you need to run development server for the Test project you should do

cd ~/projects/gae/google_appengine/test/
./run

Sort by the key

To sort query by the key:

model = MyModel()
model.order('-__key__') # descending sort
