Hi.
I've been lurking here whilst trying out web2py (thanks for the software,
Massimo!). I'm looking at building something similar to kpax, with a few
modified tweaks. However, when I tried to change group permissions, I'd get
this error. It's in access.py controller, change function:
Error Traceback (pastie.org) <http://pastie.org/1503100>
A little bit of poking, found an apparent solution from somebody, which was to
call the first object in the list, as opposed to the variable directly.
This didn't work for me (for some reason), so I have provided another fix,
which appears to work.
I don't know where or how I can submit this as a patch, so I thought the group
could have it.
The most interesting lines are the last few. I basically take the first segment
of the *request.vars.forward* variable, split it & remove leading space (which
for some reason is there), then call redirect with the URL decorator.
I hope it's of some use to somebody...
