Hi, I find it very great that now I can make my own Z Objects very easely. I'm only not so sure when to use ZClasses. Pardon me, for questioning this, but it seems that I still don't have the right view for working with Zope and it's Classes. I can imaging that using ZClasses is great for people working on the Zope web application. Correct? But, I don't see any possibilities to let end users, use ZClasses. But, I guess, I'm again wrong on that point. Can somebody clearefy my mind about this with an example : I take the example Amos gave : i.e. The CDProduct ZClass. We've created it, so now it's pretty easy to create a Z CDProduct all over the Zope web application. But how can you use this for the end-users. Let's say, I want to be able to let people enter CD's into a database. Then Z Classes aren't usable? Do you then have to create forms like we do now? Isn't it possible to let the user browse to a ZClass, the ZClass automatically creates a form which the user then can fill in. The data is sended back and a database is updated. I've read the Trinkets tutorial, but I don't understand it quiet well... Can you store ZClasses with a container? Tom.
