$Id$
Generic Views
=============
OK, there aren't really generic views. Already the first implementation we
want to look at is a specic one: It is based on Zope Page Templates and
uses the classic CMF/Zope 3 approach: The template belonging to a view
calls a `main` macro and fills a slot there. But at least the template
implementation is decoupled from the view, so we are able to put a lot of
generic functionality into the view.
But in order to make a ZPT work we need a Zope-compatible request, so we use
the standard Zope 3 TestRequest.
>>> from zope.publisher.browser import TestRequest
>>> from cybertools.web.view import View
>>> view = View(None, TestRequest())
>>> view.render()
u'<html...<body>...</body>...</html>...'
