Hi!
Some one could help me to construct a correct __bobo_traverse__ or wrapper
for my necesities.
The clues:
I have this model of __bobo_traverse__:
def __bobo_traverse__(self, REQUEST, nombre):
obj = getattr(self, nombre, None)
if obj is None:
self.REQUEST.set('TraversalRequestNameStack',
self.REQUEST["TraversalRequestNameStack"]
+ [nombre])
if hasattr(self, 'index.html'): return getattr(self, 'index.html
')
else:
resultado = self.__call__()
if type(resultado) == type(unicode()): return
WrapperUnicode(resultado)
elif type(resultado) == type(str()): return
WrapperStr(resultado)
elif type(resultado) == type(dict()): return
WrapperDict(resultado)
else: return resultado
return obj
With this Wrapper classes:
class WrapperStr(str):
""" """
__roles__ = None
def __bobo_traverse__(self, REQUEST, nombre):
obj = getattr(self, nombre, None)
if obj is None: return self
else: return obj
class WrapperUnicode(unicode):
""" """
__roles__ = None
def __init__(self, cadena):
self.cadena = cadena
def __bobo_traverse__(self, REQUEST, nombre):
obj = getattr(self, nombre, None)
if obj is None: return self
else: return obj.__of__(self)
def __call__(self):
return self.cadena
def __str__(self):
return str(self.cadena.decode('latin-1'))
class WrapperDict(dict):
""" """
__roles__ = None
def __bobo_traverse__(self, REQUEST, nombre):
obj = getattr(self, nombre, None)
if obj is None: return self
else: return obj
With this version I have the security problem I'm asking this days. The last
opinion was the Wrapper classes are the problem but you could see the
wrappers I can do with the information I have
But if I change the __bobo_traverse__ to this:
def __bobo_traverse__(self, REQUEST, nombre):
obj = getattr(self, nombre, None)
if obj is None:
self.REQUEST.set('TraversalRequestNameStack',
self.REQUEST["TraversalRequestNameStack"]
+ [nombre])
if hasattr(self, 'index.html'): return getattr(self, 'index.html
')
else:
obj = getattr(self, 'lanzador', None)
return obj
Where lanzador is a page template with this code:
<tal:b tal:replace='structure here' />
Then it works perfect!! (we can conclude, then, that Martijn has good clues
about the problem, thanks again!)
Here my petition of help:
Could someone explain or point me to how the wrappers need to be? I don't
like so much the idea that all my work depends on a page template with 1
line of code if I could implement it at product code
Thank you!
