... Hmmm, I wonder if one could hack it by avoiding '__setattr__', e.g.:
for cat in catalogs: object.__dict__['default_catalog'] = cat object.index_object()
cat._p_deactivate() # throw away changes
You probably mean "object._p_deactivate()". This will not work when "object" was modified before.
But why don't we avoid the whole thing and just call the catalog directly:
for cat in catalogs: cat.catalog_object(object, object.url()
Usually, "object" will not have an "url" method (or attribute). Apart from that, this is a very good idea. An alternative could be the use of a wrapper: from ExtensionClass import Base class _Wrapper(Base): def __init__(cat, obj): self.default_catalog = cat self.__obj = obj def indexObject(self): self.__obj.indexObject.im_func(self) ... similar for the other indexing related method ... def __getattr__(self, key): return getattr(self.__obj, key) -- Dieter
