Alternately, with more magic you could include the date as part of the URL. (/some/place/form/1999-05-14)

Would Ty, or anyone else, care to expound on what this magic might be?

I have an application I am working on which could really use something like this, but my brain is short-circuiting trying to figure out how to achieve it in a dynamic fashion.

Putting the information in the actual URL is easy, that just involves using DTML and the var tag to format the URL: If the var 'blah' equaled 'aling': <a href="/my/ding/<!--#var blah url_quote fmt=spam-->"> The trick is getting the 'aling' object to be traversable. There are several ways to make an object traversalbe, or another way of putting is is: ZPublisher tries several different traversal mechanisms in this order: Example URL: /my/ding/aling/ call __bobo_traverse__: my.ding.__bobo_traverse__(request) If the object 'ding' does not have a __bobo_traverse__ method then ZPublisher tries: getattr: my.ding.aling (note: '-' is illegal in a python name, so this first method obviously wont work for a date with dashes in it) If this fails with a 'AttributeError' exception, ZPublisher tries: getitem: my.ding['aling'] (this would work for items with '-' in them) If this fails, ZPulisher gives up and raises a 'NotFound'. -Michel
