Thanks for the code! I've generalized that a bit and adapted it to my purpose:
class MyController(controllers.Controller):
def _get_root_url(self):
return self.breadcrumbs[-1][0]
root_url = property(_get_root_url)
def _get_breadcrumbs(self):
try:
return self._breadcrumbs
except AttributeError:
cherry_trail = cherrypy._cputil.get_object_trail()
href = '/'
crumbs = [('/', 'Home')]
for item in cherry_trail:
if isinstance(item[1], controllers.RootController):
continue
if isinstance(item[1], controllers.Controller):
href = "%s%s/" % (href, item[0])
crumbs.append((href,
getattr(item[1], 'title', item[1].__class__.__name__)))
self._breadcrumbs = crumbs
return crumbs
breadcrumbs = property(_get_breadcrumbs)
Maybe somebody else will find this useful too.
