Hi List, I've been working using Zope to build a set of components intended to be abstract and reusable. These components currently exist as folders, with each folder having a set of page templates, Python scripts, and SQL queries (and sometimes other stuff). The idea is that for a given site, I will declare that I am utilizing component X, and the component's default scripts and templates will allow for all the functionality I need. However, there are many cases where I need to override a given template or script in a component. I have this working to a degree, by having a folder called "site" in each component's folder, and in that folder I have the replacement scripts/templates/etc. Then I simply change my references like the following: "componentX/HTML/someTemplate" becomes: "componentX/HTML/site/HTML/someTemplate" "componentY/someScript" becomes: "componentY/site/someScript" As I said, this works. The problem is the folder that contains the components has to be copied to each site's root folder. What I would like is a system where in the root of my zope, I can have one folder for the components, and then in each sites folder, I can create the overriding scripts. This is complicated a slight bit by the fact that I need all URLs on a site to be within that site's folder. So I need to be able to call a URL like: "http://www.somesite.com/components/catalogue/buyStuff" and if I have overridden the "buyStuff" script, have it call the overridding script, but if I haven't, I need it to somehow acquire "zopeRoot/components/catalogue/buyStuff". I'm sure I haven't explained this properly, or there's something obvious I'm overlooking, so please ask questions as if I were terminally stupid :) Thanks for your time, Alec Munro
