nipap-www - 'HTTPFound' object has no attribute 'exception'

[cholin]

I installed NIPAP recently (using current master) and wanted to try nipap-www. Unfortunately after installing nipap-www (python setup.py install) and starting nipap-www through paster I always got an AttributeError when I tried to open the web interface in my browser. Error log looks like the following:

$ paster serve nipap-www.ini

If you google for AttributeError: 'HTTPFound' object has no attribute 'exception' you will find https://stackoverflow.com/questions/24103865/pylons-redirect-gives-attributeerror-httpfound-object-has-no-attribute-exce. Seems by default python setup.py install in nipap-www installs the wrong version for WebOb (see https://github.com/SpriteLink/NIPAP/blob/master/nipap-www/setup.py#L12) or nipap-www is using deprecated/removed functionality of WebOb. To fix this I had to install WebOb 1.3.1 manually on my ArchLinux system:

pip install WebOb==1.3.1

I think this should get fixed.

So, you essentially want a requirements.txt file for nipap-www pinning the required modules and avoiding this situation then...
