Minimum setup for getting Django 1.3 to work in Google App Engine. Do this in this order: 1. add .bash_profile lines 2. django-admin.py startproject mysite # generates mysite directory) 3. in GoogleAppEngineLauncher: create project within the mysite directory you just created (=> generates main.py and app.yaml, etc.) 4. alter main.py and app.yam…

.bash_profile
