However, usually, exceptions are no sequences and an exception cannot be matched with (e1, e2). Try except StandardError, e: (and, of course, change the following line accordingly). Whenever you get exceptions, you should look at the error description in your error_log object (in the Zope Root Folder of the ZMI). There, you can see (in the so called traceback) where the exception has been raised. This is invaluable information. Usually, error_log ignores Unauthorized. Therefore, you must temporarily reconfigure the error_log in order to get the information. Should you have problems to understand it, come back with the information. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] How manage error with zsql
hi,
I think you should write in a python script:
try:
result = context.insert_data.zsql
msg = 'data inserted'
except ZeroDivisionError:
msg = 'ZeroDivisionError occured'
return msg
and in your tal you write:
div
tal:content=context/MyPythonscript
/div
allways try to put logic in a python script. it is *far* easier than writing
complicated tal
