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/

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*

New Book in the Mail!
