Tutorial part 4 IndexError

[jonathan_ou]

I am using python 2.5 with django 0.96 rev 5005 using mysql database.
When I try to cast a vote via web forms in part 4 of the tutorial, I
get the following error after I select a choice and submit the form:

Traceback (most recent call last):

IndexError: list index out of range

The code and template html is directly copied from the tutorial
website (copy and paste). Yet for some reason this error continues to
pop up and django's own debug html page doesn't even load. The error
messages are entirely in plain text.

Does anyone know how to solve this problem?

I smell the sense of an end-of-line convention problem in django's
debug view. Could it be your sourcefile uses '\r' for end of line
where django expects a '\n' ??

Thanks! That was exactly it. I was using Mac OSX to develop and they
use a different line ending character than Unix. Everything works
correctly now.

Thanks again.
