Django - in debug.py list index out of range

Question

I can't figure out why I'm getting this error. Please help.

Traceback (most recent call last):

File "C:\Python26\lib\site-packages\django\core\servers\basehttp.py", line 280, in run self.result = application(self.environ, self.start_response)

File "C:\Python26\lib\site-packages\django\core\servers\basehttp.py", line 674, in call return self.application(environ, start_response)

IndexError: list index out of range

can it be due to using notepad++?

Answer 1

I know this answer is a bit late but it could help others :)

In my case, that was because I didn't restarted apache and the old files where used and conflicted with the new (I don't know how though). A simple apache restart fixed the problem (graceful should work too I think).

In a general way, it seems the error occurs when there is a conflict in the files and not a problem from your code. Try removing the pyc files, restarting django, apache or what is currently using your python code right now.

That worked for me.

Answer 2

The source file contains Macintosh line breaks (\r) that is not supported by the djangos debug page.
