Chris Thanks for your reply. I hadn't thought of using ZWikiWeb, but given that I do need to make instances of a master site, do you think that this could be done using ZWikiWeb? Instead of inheritance for the folders, the mechanism I'm investigating now is prototypes (a la JavaScript and Self objects). Hamish Lawson Do You Yahoo!?

Hi Hamish, I'd suggest downloading the ZWikiWeb product from: http://www.zope.org/Members/chrisw/ZWikiWeb It does pretty much exactly what you're talking about. It's doesn't take very long to knock up a product like this and I don't think I even used ZClasses. My basis was the example stuff from the Zope Content Managers Guide. I'm guessing this is what you're trying to do. If you're looking into using inheritence (so for example, your tutor changes his example, which causes all the instances to be updated) then you'll need to use ZClasses. I have vague memories of the Zope Developers Guide covering this, if not, try BeeHive's ZClass guide. cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

I may have misled you about what I meant by the alien stuff that I wanted tutors to avoid seeing. I envisaged turning a tutor's site into a product that could be instantiated. In order not to make copies of static files, I reckoned that each folder in the tutor's original site would have to be made into its own ZClass in order that the static files that were missing from instances of the site could be found through inheritance. I'm happy with a tutor's site being moved into the Products folder; the stuff I wanted tutors to avoid seeing wasn't other products, since I think it should be possible to provide them with an interface that takes them straight to their own product. Rather I wasn't sure whether it was possible to turn a tutor's site into a product that used folderish ZClasses instead of ordinary folders, yet still have it feel like their old site. One issue with what I'm suggesting is this idea of every folder in the tutor's productised site really being a folderish ZClass. I'm bothered by this profusion of ZClasses. I think what I really need is the concept of prototype folders, whereby if a folder in an instance of the site didn't itself contain the required object, its prototype folder would be looked in instead; the folders in the product would be just ordinary folders rather than individual ZClasses, and folders within the product instances would all be instances of a single PrototypedFolder class (though obviously pointing to different folders as their prototype), thus drastically reducing the number of classes required. But I don't know whether such a prototype mechanism exists for Zope. Hamish Lawson University of St Andrews, Scotland Do You Yahoo!?

[Zope] Generating products that perform a smart clone of a master site?
I'm exploring the use of Zope for creating learning environments in higher education. One of the requirements is for a tutor to be able to create a mini site that includes static files along with more active objects like discussion boards. Furthermore they need to be able to make different 'instances' of this site for use by different groups, such that each instance of the site conatins unique instances of any contained active objects (such as a discussion board). The obvious approach would be to just copy and paste the folder containing the master site, but there are a couple of problems with that: (1) changes to the master site will only be reflected in new instances of the site, and (2) a lot of static files could be getting copied each time. What I think I need to do is to develop a facility that makes a tutor's site into a product. Instantiating such a generated product should make a smart clone of the master site, smart in the sense that only active objects are actually cloned, but static files are shared among all instances of the site. I suspect that ZClasses might be involved to achieve this, but are there any issues with the fact that a master site could contain folders? Furthermore I'd like a tutor to be able to visit their productised site to update it, without seeing a lot of alien stuff; changes to the master site should be reflected in all instances of the site. Am I on the right lines here? Any pointers would be appreciated. Hamish Lawson University of St Andrews, Scotland Do You Yahoo!?
