[Zope3-Users] Re: Still a skinning problem

Florian,
if you want the url to your current site implement this :


class SiteUrlView(object):

     def __call__(self):
         return absoluteURL(hooks.getSite(), self.request)

And register a page :

   <page
       name="site_url"
       for="*"
       class=".views.SiteUrlView"
       permission="zope.Public"
       />

Now you can use context/@@site_url anywhere.
