Notes while running through the Django tutorial

First, browse the overview here: https://docs.djangoproject.com/en/1.6/intro/overview/

The real tutorial is here: https://docs.djangoproject.com/en/1.6/intro/tutorial01/

Oops, have to install (https://docs.djangoproject.com/en/1.6/intro/install/) before doing the tutorial.

Ahh, I guess it *is* installed:

OK, back to the tutorial.

2 directories, 5 files

sidebar to set up git repo for the code

Tried running the development server on weasel, but ran into firewall rules. Moved development to a workstation which is more in the spirit of the tutorial.

Had to install django there... 

root@ferret:~/git/church-django/mysite# apt-get install python-django

And get the codebase 

rday@ferret:~/git$ git clone ssh://weasel/drobo2/git/church-django.git
Cloning into 'church-django'...
