Hi,
I'm trying to proxy a persistent content object with a non-persistent
object that intercepts calls to absolute_url. The proxy object looks
like this::
class Proxy:
def __init__(self, context, brain):
self.context = context
self.obj = obj
def absolute_url(self):
return munged_url_for_obj
def _getLocal(self, key):
if self.__dict__.has_key(key):
return self.__dict__[key]
def __getitem__(self, key):
# Defer to the brain for most things.
return self._getLocal(key) or self.obj[key]
def __getattr__(self, name):
# Defer to the brain for most things.
return self._getLocal(name) or getattr(self.obj, name)
This proxy object gets used in a page template. This works fine (i.e.
it returns `munged_url_for_obj') when I use an expression like
"python:proxy.absolute_url()". However, when I use a normal path
expression, like "proxy/absolute_url", I get back the unmunged url (i.e.
obj.absolute_url()).
I'm a little confused as to what's going wrong for me. My best guess is
that Products.PageTemplates.Expressions.restrictedTraverse (called
Products.PageTemplates.Expressions.SubPathExpr._eval) isn't designed to
like my proxy object. But I'm not even sure of that much, and I can't
figure where to put a pdb.set_trace() as I can't put it in the obvious
place just before the "proxy/absolute_url".
Any ideas?
Tim
