Re: Confused by attribute error
Hi.
It would be really helpful to be able to look at your function as
well. My
Guess is that the problem lies there, since this is happening when you
call the function. Even if the problem is within django it would be a
lot
easier to find when looking through your function to see what it does.
Also please post it at dphaste or some other simelar website.

Also i don't comment until i put my code into production (bad habit,
yes i know :x), so let me know if you need me to throw in some dirty
comments to make it more readable.

Re: Confused by attribute error
So the fun continues. I realized that i did not need to use the login_required decorator on this function since it's just tossed around in the backend, so i took that out thinking it would prevent decorators.py from being called. When i hit the function above now, it posts the same error with a different request (can be viewed here http://dpaste.com/21238/ ). The string object it's having trouble with is this: '/home/mipscomp/public_html/support/helpdesk/exported/03_30_09.txt I'm pretty confused at this point, as i've never seen this error before. And the last time i recall working with this code, it worked flawlessly. Ridicule and ideas are greatly appreciated.

Re: Confused by attribute error
Bingo! Looks like i was lazy with my code and threw decorators on ALL the functions, not just my views. There was a lingering decorator on the send_file function that i did not notice. Thanks for pointing out my sloppines;) You saved me a ton of time today, double thanks!
