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

[Pletli Antal]

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 ###################################

The "Transient Object Container" (that's the session container) has too
scripts for this. You configure them in Zope's configuration file.
