Thank you for your help
I would like to overrite some properties in my product with a know property
(Maestro)
For example I define an object:
ObjectA
PropertyA
PropertyB
PropertyC
Maestro - this property has a transversal path to ObjectB
ObjectB
PropertyD
Then I would like to call
ObjectA.PropertyD - these code calls ObjectB.Property
With these code I would like to construct a soft link mechanism
I try to override the __bobo_traverse__ with these code:
def __bobo_traverse__(self, Request, Name):
Maestro = getattr(self, '.Maestro', None)
if Maestro is not None:
obj = self.unrestrictedTraverse(Maestro.contenido)
Acquirido = obj.__of__(self)
return getattr(Acquirido, Name)
return getattr(self, Name)
these override works fine but is not recursive in the Maestro structures
If I use these other override :
def __bobo_traverse__(self, Request, Name):
Propiedad
Obj = self
Maestro = getattr(Obj, '.Maestro', None)
Paso = 1
while Maestro is not None:
Obj = self.restrictedTraverse(Maestro.contenido).__of__(self)
Maestro = getattr(Obj, '.Maestro', None)
Paso += 1
if Paso == 15: break
if hasattr(Obj, Name):
return getattr(Obj, Name)
return getattr(self, Name)
The recursive Maestro mechanism works fine but in the ZMI I obtain the
object in the Maestro structure. For me is an error because I can't see the
real content of the object
Do you understand my problem?
Thanks again!!!
PD: sorry for my english!

Can I know the execution contexto of an object?
I would like to know if the object is call by ZMI or DTML or Page
Templates etc
is it posible?
Perhaps; I am not sure I can see why it would be *desirable*. Given
that Scripts, DTMLMethods, etc., try pretty hard to push themselves onto
the execution stack just as though they were methods, you could probably
introspect the result of calling 'sys._getframe(1)' to figure out what
kind of thing called you.
From the Python Cookbook, #14.7:
def whoami():
... Return the name of the calling function.
...
... import sys
... return sys._getframe(1).f_code.co_name
...
def foobar():
... print whoami()
...
foobar()
foobar
