Install git[edit]

It's an insult in British English, but git is also an awesome version control tool. Here's how you install it:

Go to this page on google code and download the latest file ending in "-x86_64-leopard.dmg" (1.7.2.3 as of this writing). Once it's downloaded, double click to open. You'll see something like this:

File:Git-screenshot.png

Double-click the .pkg file to install. Once that's done, close all your open Terminal windows, and open a new one. Cut and paste the following into the new Terminal window:

    git --version

It should respond with something like "git version 1.7.2.3".

Tell git who you are[edit]

  • Open up a new Terminal window.
  • git config --global user.name "Your Actual Name"
  • git config --global user.email "Your Actual Email"

If this doesn't produce an error, congratulations! You have a successful install of git and you can move on to the next section.

Test it:

git config --global user.name
git config --global user.email

Download and install Django[edit]

  • Open a Terminal and type:
cd /tmp/
curl -L  http://www.djangoproject.com/download/1.2.5/tarball/  -o Django-1.2.5.tar.gz
tar zxvf Django-1.2.5.tar.gz
cd Django-1.2.5
sudo python setup.py install

Make sure Django is working[edit]

  • Open a Python prompt, and type this in:
import django

If you get an error, get help! Otherwise, you're done.

Create an SSH public key[edit]

You'll need one of these to push your work to Github.

  • Open up a new Terminal window.
  • ssh-keygen -C Your Actual Email -t rsa (email should match git config setting)
  • Hit enter to accept default location for ssh key.
  • Hit enter to accept blank passphrase (if computer is shared with other people, as in a work laptop, you should create a passphrase). Hit enter again to accept blank passphrase (or enter passphrase again).
  • Your brand-new public key is now stored at ~/.ssh/id_rsa.pub.

Install the KomodoEdit text editor[edit]

We'll be using the KomodoEdit text editor during the workshop, though you are free to use a different editor if you prefer. It must be a plain-text editor, such as vi or Textmate. Microsoft Word and other word processing programs won't work. If in doubt, use KomodoEdit.

Installation steps:

  • Download the KomodoEdit installer.
  • Double-click the file once it's downloaded.
  • It will open an installer with a KomodoEdit icon and a picture of your Applications folder. Something like this:

File:Komodo-Edit-5.png

  • Drag KomodoEdit into your Applications folder.
  • Unmount the installer disk image by dragging it from your desktop to the trash.

Verify you can create a new Django app[edit]

  • Create a folder on the desktop called django_projects
  • Open a new Terminal window and type the following:
   cd ~/Desktop/django_projects
   django-admin.py startproject myproject
  • Both commands should provide no output.
  • Once that's finished, type the following in the Terminal window:
   cd myproject
   python manage.py runserver
  • The first command should produce no output. The second command will put out a bunch of output, then just sit there until you cancel it (2 steps from now).
  • In your browser, go to http://localhost:8000/
  • Back in the Terminal window where you ran python manage.py runserver, type control-c to kill the server.

Install SQLite Firefox add-on[edit]

SQLite Explorer is a piece of software that lets you browse SQLite databases. It's written as a Firefox add-on.

Even if you already have a browser like Chrome, you'll need the latest version of the Firefox web browser. (You may need to upgrade even if you already have Firefox installed.)


If you already have Firefox[edit]

Open it, and then go to the Firefox menu (top left of the screen). Select "About Mozilla Firefox."


You'll get a window, like the one below, that shows you what version of Firefox you have. Write down that number!


Now go to the Firefox homepage and see what the current version of Firefox is. If it's the same major version (such as 3.6 - you can ignore the third part of the number) then you're good. You don't need to upgrade.

If it's a different major version, then you need to upgrade. Download it from the Firefox homepage and double-click to install.

If you don't have Firefox yet[edit]

Go to the Firefox homepage and click the big download button. Once you have the file, double click and follow the instructions to install.

Install the SQLite Manager Firefox Plugin[edit]

Open Firefox, and then go to the Tools menu and select "Add-ons." Click the "Get Add-ons" button at the top. Enter "SQLite" where it says "Search all Add-ons." The first thing that comes up should be SQLite Manager. Click "Add to Firefox" and then follow the instructions to install it.

If you have trouble installing, double-check that your Firefox version is at least 3.6.

Now go back to the web app install instructions
