Hi folks,
I have been bitten by the Python bug and have decided to jump
into web development using Python and what can I say, I found Django's
charms too hard to resist! But there seems to be some trouble in
paradise ... lemme explain in brief -
I setup up Django 0.95 on my system alongwith Python 2.5. Installation
went off smoothly without any errors. To test the configuration, I
started following the steps and examples given in "The Django Book".
The code is basically the following:
from django.http import HttpResponse
from mysite.views import current_daytime
def current_datettime(request):
now = datetime.datetime.now()
html = "<html><body>The current time is %s.</body></
html>" % now
return HttpResponse(html)
"mysite" being, of course, the project created using the command
"manage.py startproject mysite" from the ...\django\bin directory. I
started the built-in Django server using the command "manage.py
runserver 8001" (note:
as required, I had suitably modified the 'urls.py' file in the mysite
directory).
The server runs fine. I even get the initial server screen (before
making the above modifications). However when I access the server
through the browser as "http://127.0.0.1:8001/now"; ( note: the
'urls.py file reads as:
from django.conf.urls.defaults import *
from mysite.views import current_datetime
urlpatterns = patterns('',
(r'^now/$',current_datetime),
)
)
However, the browser ( I tried on both IE and Mozilla Firefox ) throws
up the following error :
(Sorry, it's quite a bit long!!!)

You're seeing this error because you have DEBUG = True in your Django
settings file. Change that to False, and Django will display a
standard 500 page.
I figured that there was some problem with the get_mod_func method in
the urlresolvers.py file inside django\core directory and that the
'rindex' method was being applied to a non-string. Tried some mods
using "str" but didn't solve the problem.
Could someone please explain what's going on and how to fix the
problem?
Thanks,
Timmy Jose.
