// What I'm not sure about is how to have Zope automatically // display the photo // for a day, then archive it. Would a boolean property of the // ZClass work? Is // it possible to have Zope set the property of a ZClass instance // at certain // time? Any thoughts on how this would be designed? Hi Tim, Here's some code I use with a simple NewsItem ZClass that only displays objects that have not yet "Expired". With a little modification, it could be used to test a "DisplayDate" value and if it matches the current date, the photo would be displayed. That way you could load a bunch of photos into your site at once and give them specific display dates. If more than one had the same date, they would both be shown. "Expires" is a property of my NewsItem ZClass that is of type "date". "Expires+1" just adds a day to the expiration date so that my news items are displayed up to, and including, their expiration date. The NewsItem ZClass has a meta type of "News Item," which is used in the "in" statement. "view" is a method of the ZClass that simply formats the NewsItem for displaying in the browser. <dtml-with News> <dtml-in expr="objectValues('News Item')" sort=id reverse> <dtml-if "ZopeTime().lessThanEqualTo((Expires+1))"><dtml-var view><br></dtml-if> </dtml-in> </dtml-with> Hope it helps... Eric.
