Django IRC & Mibbit.com

VoiDeT — Mon, 10 Nov 2008 19:36:52 +0000

If you would like to get some realtime Django help from the experts i recommend you have a look at the Django IRC channel. You can connect @

Django IRC Channel
Server Address: irc.freenode.net
Channel: #django

If you are new to Django i recommend that you also join #django-newbie

You can connect via a webbrowser if you couldn’t be bothered using an app or finding an irc application that suits you. I really recommend using mibbit.com. Don’t forget to create a user name and password that way you can store the favourite IRC channels!

Up to Chapter 5 of this book. Already i know what the deal is with views, have made a full admin panel which error checks all entries, has categories, tagging and can generate HTML! Whoa! So good. Just notice that you may need to use SVN number 7966 and tagging r133 which can be brought down with:

Django Trunk:
svn co -r 7966 http://code.djangoproject.com/svn/django/trunk/

Tagging:
svn co -r 133 http://django-tagging.googlecode.com/svn/trunk/

Practical Django Projects

It was this error that spent 2 hours of my day today:

ImportError: No module named coltrane

I had included my PythonPath entry manually into my MacOSX home directory via:

vi .profile

and entering:

export PYTHONPATH=/Users/myname/mydjangodirectory:$PYTHONPATH

This indeed works, but i was using a super user account to run all of my commands because i wanted the development web server to run over the default port 80, of which the normal user account doesn’t have the privileges to. Silly me, because setting the .profile is only local for the user you’re using, not global. Of course i stopped running the sudo commands and just used the logged in user, and all was fine!

*By the way to save in Vi and exit: hold shift + ZZ*

Django and Subversion Hourly Updates

VoiDeT — Sat, 30 Aug 2008 00:26:42 +0000

So if you are developing with Django and python you may be running off the Django SVN trunk. It can be a pain constantly running the update command when you simply want to be up with the development. Of course you would run this on a development server and not a production server! But i have figured out a way to get Subversion to update the django trunk every hour. You can do this on a unix system or mac!

Firstly you need to get into your superuser account and run the cron editor. this can be done via: sudo crontab -e
You will be asked for your super user password. Next up find a new line in the editor, usually vi, and type this: 0 * * * * svn up /home/user/django_trunk/ >> /home/user/log.txt
That’s it! Simply change the paths to match your system. So the /home/user/django_trunk would be the path to where you first installed the django trunk. The second path is where a log file will be produced to show you the updates that the subversion has updated django to.

If you would like to know how to install Django via subversion go to http://www.djangoproject.com/documentation/install/ and look down the bottom for installing development version!

Django Part 2!

VoiDeT — Thu, 28 Aug 2008 00:11:36 +0000

So i have been reading through the python and django books a bit more. The first one, Developing websites with Django was great, very project based, but it didn’t really go into the depth i needed in order to start programming my own websites. So i picked up my other book:
