RE: [Zope] How can I store session data to db on login/logoff events ?

12 Oct 2006

      Thanks Dieter, it's work.

But i have a problem with this:

When I ran the test python script (see below) in Zope or I called the
url directly from the browser , I got an error: 

Error Type: KeyError
Error Value: 'SESSION'

##### Python test script #######

from Products.PythonScripts.standard import html_quote
request = context.REQUEST
RESPONSE =  request.RESPONSE
session = request.SESSION
session.set('VAR',99)

This is the simple external event handler script

############ external module to catch session changes
###################
def onSessionStart(item, container):

    from logging import getLogger

    request = container.REQUEST

    user = request.AUTHENTICATED_USER.getUserName()

    LOG = getLogger('DEMO')
    session = request.SESSION

    LOG.info( "Item data: %s" % item )
    LOG.info( "Request data: %s" % request )
    LOG.info( "Session data: %s" % session )

And in the event.log I can see this error:

############# event.log ###################################

How can I retrieve the user SESSION data when the items are created or 
deleted from the transient object container?
The "Transient Object Container" (that's the session container) has too
scripts for this. You configure them in Zope's configuration file.
