[Zope3-Users] Re: Seeking advice on Zope implementation - II

[Philipp von Weitershausen]

Hi there,

I'm CC-ing zope3-users because that's the list for user problems 
(zope3-dev is reserved for zope 3 development).

As somebody who has worked on Zope 3 documentation I'm extremely 
satisfied to hear that.

Views (ZPTs are registered as views) are looked up for content classes, 
that is true. That doesn't mean the view necessarily must have something 
to do with the content class. You could simply register all your ZPT 
pages and browser view classes (you need those for all the Python logic 
that you shouldn't put in ZPTs) e.g. for IRootFolder. Then they'd be 
available at http://localhost:8080/@@viewname.html.
