[Zope] View classes based on Page Templates in Zope2

Something I like about Zope3 is the View classes. What I like about it especially is that it's a brilliant place for putting in little extra silly python methods that are specific to your template rather than the object class. Eg. class ViewProduct(BrowserPage): __call__=ViewPageTemplateFile('productview.pt') def showPrice(self, product): return "£%.2f" % product.getPrice() What options do we have for this in Zope2? If Five is the answer, what options do we have without Five? Has anybody written a convenient class like this? Perhaps based in PageTemplateFile or something? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
