pyramid debugtoolbar raising exception while trying render variables in post request.

you have enabled in development environments, disable running application production.ini. evaluate if behaviour different.

btw: run pyramid tutorial on authentication protect view authenticated users, not swallow exceptions way , use logging statement instead of printing. pyramid docs/tuts apply these techniques.
