Boston Python Workshop/Friday handout/Windows
About Django on Windows
- These instructions should work for all versions of Windows from XP on to Windows 7.
- You may need to login as Administrator, or give the Administrator password when installing some programs, depending on your Windows version and user settings.
Open a Command Prompt
- Open a command prompt window, and keep it open along with your browser. Much of installing Python and using Django is typing commands and hitting <enter>. Your experience using Python on Windows greatly depends on your making friends with the command prompt window.
- This is also called the command prompt, command window, command-line window, MS-DOS or DOS window.
- Try these recommendations:
- Tip: clear screen
If you ever want to clear the "output history" to get a clear screen, type:
- Tip: command history
The command prompt window stores a "command history." To view and re-run previous commands, use the <up arrow> and <down arrow> keys. You can also edit a previous command and run it--this is handy for long commands, or fixing mistakes.
- Tip: copy and paste
In the instructions below, where it says: "In the command prompt type:", you can, much more easily, copy the command from this page, and right click in the menu bar or command prompt window, then click on "Paste", then hit the <enter> key.
- Go to http://python.org/download/ and download the latest version of Python 2.7 (2.7.1 at the time of writing).
- Test your Python install in the command prompt:
You should see something like
Python 2.7.1 (r271:86832, ...) on win32 Type "help", "copyright", "credits" or "license" for more information. >>>
and press Enter, and you are back to the command prompt.
Install Git for Windows
- Go to the downloads page for GitBash
- Download the top .exe file link with the Summary something like "Full installer for official Git 1.7.x.x"
- Run the install.
Note: You can't just click through the installer. You have to answer some questions!
- In the "Select Components" dialog, make sure the checkboxes "Associate ... configuration files ..." and "Use a TrueType font ..." are checked.
- Important: In the "Adjusting your PATH environment" dialog, make sure "Run Git from the Windows Command Prompt" is selected.
- In the "Configuring the line ending conversions" dialog, make sure "Checkout Windows-style, commit Unix-style line endings" is selected.
- To run git, open Programs > Git > Git Bash
- Then to test the Git install and see Git commands, type this into the Git Bash prompt:
Note: From here forward, when we need a command prompt, we'll use the Git Bash prompt, because it is more featureful.
- Set up Git with your name and email to tag your code changes. In the command prompt type:
git config --global user.name "Your ActualName"
- Replace Your ActualName with your actual name.
git config --global user.email YourEmail@domain.com
- Replace YourEmail@domain.com with your email address.
git config --global user.name git config --global user.email
To have colored output, in the command prompt type each line followed by <enter>:
git config --global color.diff auto git config --global color.status auto git config --global color.branch auto
Install SQLite Manager
- If you already have Firefox installed, verify that it is version 3.5.0 or greater. (Help -> About Mozilla Firefox. The version number is right under the "Firefox" title.)
- If you don't have Firefox installed, or it's an older version, install Firefox.
- Once it's installed, open Firefox and go to Tools -> Add-ons. At the top of the add-ons window, click "Get Add-ons."
- There will be search box directly underneath "Get Add-ons" that says "Search All Add-ons." Enter "SQLite" (without the quotes) in the box and hit enter.
- SQLite Manager should be the top result. Click "Add to Firefox..." (If SQLite Manager isn't in the results, check the spelling - SQLite only has one L. Also, check that you have at least Firefox 3.5.)
- Wait for the countdown, then click "Install Now."
- In the Add-ons windows, click "Restart Firefox."
- Once Firefox restarts, the Add-ons window should say "1 new add-on has been installed." Go to the Tools menu and verify that there is an option for SQLite Manager.
You need a text editor to do Python. If you already have a preferred text editor, such as vi, emacs, jedit, etc., you can skip this step. It must be a plain text editor and not something with styling like Microsoft Word.
When in doubt, use KomodoEdit.
- Download KomodoEdit here.
- Double-click to install.
Create an ssh public key
You'll need one of these to work with Github.
- Get into a GitBash 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.pubinside your Windows profile.
Note: The ssh-keygen command will give you a bunch of output. You don't have to record that output anywhere.
- Open a new GitBash window. Type each of these, and press enter at the end of the line.
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 /c/python27/python setup.py install cd ..
Verify you can create a new Django app
- Create a folder on the desktop called
- Open a new GitBash window and type the following:
cd Desktop/django_projects /c/python27/scripts/django-admin.py startproject myproject
- Both commands should provide no output.
- Once that's finished, type the following in the Terminal window:
cd myproject /c/python27/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
manage.py runserver, type control-c to kill the server.
Ok, there is one more step. You won't be using the test project in the workshop; we just created it to make sure everything was working. You should delete it now to reduce confusion during the workshop. Don't worry about losing information; it just has the test project in it.
- Exit the GitBash terminal
- Drag the myproject folder (inside django_projects) to the Recycle Bin. Leave django_projects on the desktop.
You have everything you need to write a Django web application in Python.
...on your machine.
The next set of directions help you use alwaysdata.com and its free-of-cost hosting.
PuTTY is a program we'll use to log in to the server where your Django code runs.
- Go to the PuTTY download page
- Choose the putty-0.60-installer.exe file.
- Run the installer, and now you will find PuTTY in
Now go back to the web app install instructions
