Learning python/django

In my quest to learn how to use python within the django framework, the most difficult thing was the development environment, and getting to the point where I could play learn, practice and experiment. Here are some steps that I took to get to that point.

I’ll add to this as I can, but mostly I’m using it as a handy resource that I can access while continuing to learn.

    super(ListField, self).__init__(*args, **kwargs)

# You will need to run these with superuser permissions.
# Either prefix `sudo` to all commands, or switch user

# Be very careful when you switch user
sudo su - root

# Update all the packages
yum update

# Install the basics - python27, gcc, svn, git, httpd, make, uuid

Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html
