John, Sorry, its error_tb not error_tab. David ----- Original Message ----- From: "David Hassalevris" <bluepaul@earthlink.net> To: "Zope Users" <zope@zope.org>; "John Hunter" <jdhunter@ace.bsd.uchicago.edu> Sent: Tuesday, August 03, 2004 8:37 PM Subject: Re: [Zope] debug info

Hi John,

Have you tried

try:

whatever

except: <dtml-var error_tab>

That should give a full traceback.

...

I am having a problem with roles and permissions. I find that I cannot access some pages on my site unless I have the role Manager, although I have tried to customize the roles and permissions so that other roles can access this content. Actually, this used to be working and now it is no longer working and I'm trying to figure out what has changed.

When I try and access the protected content, I am prompted for a user name and passwd. If I enter a user who does not have the Manager role, I get the error

You are not authorized to access this resource. Username and password are not correct.

If I add the Manager role for that user, however, I can then access the content.

The site is built as a python Product, and I am using ClassSecurityInfo to manage my permissions and roles for the various methods.

My question is: is there any way I can get better diagnostic information for debugging, for example what resource I am trying to acquire that I don't have permission for? I've checked the Z2.log but there is no helpful information there.

On a related note, is there any way to get zope to give full tracebacks rather than the limited tracebacks it supplies by default?

Thanks, John Hunter

I'm not using dtml in many places - rather the python API. Often times I call a method which calls other methods, etc. What I would really like is to set a debug mode so that zope always reports the full traceback, or at least a log where I can get this.

Is there no hook or mode I can set to enable this?

standard_error_message? there you should be able to do whatever you want with error message, log or print it on screen. Vahur
