[Zope3-Users] Alternatives to macros

Wed Sep 13 16:58:31 EDT 2006

I'm investigating alternatives to macros, the following appears to work, but 
does anyone see anything particularly wrong or limiting with this implementation?

Thanks,

Kevin Smith

app.py

    class PageView(BrowserView):

        content = pagetemplate.ViewPageTemplateFile('page.pt')

        def __call__(self):
            view = zope.component.getMultiAdapter( (self.context, self.request), name="masterpage.html")
            view.content = self.content
            return view()

    class NavbarContentProvider:
        implements(IContentProvider)
        adapts(Interface, IDefaultBrowserLayer, Interface)

        def __init__(self, context, request, view):
            self.context = context
            self.request = request
            self.__parent__ = view

        def update(self):
            pass

        def render(self):
            return '<a href="/">Home</a>'
