I've decided to rewrite ZCache in an OO way, so I rewrote it and called it GenericCache. First thing I'm trying to make are cached DTMLDocument and DTMLMethod. GenericCache provides a Cache class that wraps all access to the object, and if the cache expires Cache reloads its data. How it reloads is determined by overloadng a _getData method in subclasses. So in a subclass of Cache and DTMLMethod _getData would call DTMLMethod.__call__, i.e. te cache would contain the rendered DTML. I subclass Cached DTMLDocument from Cache and DTMLDocument, Cached Method from Cache and DTMLMethod. I have two major problems: 1. The DTML only renders if I put all of it inside a <dtml-with "PARENTS[0]"></dtml-with>, otherwise it doesn't seem to acquire anything. Cache inherits from Acquisition.Implict and of course so does DTMLMethod - so why isn't acquisition working? 2. The Cached DTMLMethod behaves just like a DTMLDocument - possibley because of the above problem and/or my temporary solution. That is, it doesn't act as a method of the enclosing folder but as standalone object. I'd be very grateful if anybody could point me in the right direction - I put up the code at http://www.zope.org/Members/itamar/GenericCache -- The SNAFU Principle: True communication is possible only between equals Itamar S.T. itamars@ibm.net
