I am working on a ZClasses thing that makes forms and automagically saves form data into the ZODB. I am assuming the response record (After the 'submit' button is pressed) will be written once (e.g, a test or survey) and changed rarely or never, so it is proper to use the ZODB.
I do not want to use a DB product, since if you change the form, you need to modify the table, and that is not nice, either.
So, what I want is a thing that just has Properties I can add at runtime.
Should this new ZClass descend from Folder or DTMLDocument? From the application's point of view, they are equivalently good, since both have Properties I can modify. Technically, though, which would be better?
Any Zope class can have properties, although if you want to customize the properties of each individual instance, you will need to pick up one of the two you mention (or create a new one in Python which subclasses PropertyManager.PropertyManager). In that case, select between them based on whether you want the item to be "folderish", that is, to allow adding other objects via Zope. -- ========================================================= Tres Seaver tseaver@palladion.com 713-523-6582 Palladion Software http://www.palladion.com
