It's my understanding that this can only be done in python in the Products subfolder. I did something like this with David Murray's help for a BannerProduct. I modified an existing python-based banner class and added two "maps" to each banner object called 'history_views' and 'history_clicks' indexed by a date. Here's part of code I'm using: in /Products/ Ban.py file: __doc__="""Ban Ad Classes""" __version__=0.1 from Globals import HTMLFile from Globals import MessageDialog from Globals import Persistent from OFS.Image import Image #import OFS.Image import OFS.ObjectManager import Acquisition # Various acquisition types. import AccessControl.Role # Zope Security management. import string class Ban: " A Ban Ad Class" meta_type="Banner Base Class" def __init__(self,id,title,file,content_type='',precondition=''): self.history_clicks = {} self.history_views = {} def __setstate__(self,state): Persistent.__setstate__(self,state) if not hasattr(self,'history_views'): self.history_views = {} if not hasattr(self,'history_clicks'): self.history_clicks= {} later in the code the history_views map is updated when a banner ad is viewed: keydate=time.strftime("%y%m%d",time.localtime(time.time())) if self.history_views.has_key(keydate): self.history_views[keydate] = self.history_views[keydate]+1 DV, Scott Brodsky http://scottb.homepage.com icq:2202686, Yahoo:sbrodsky2000 Romans 14:11 ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup
