Hmm, that's strange. Maybe if you call the __getitem__ function itself? : return Folder.__getitem__(self, key) It should be working though....
__getitem__ raise an exception : *Error Type: AttributeError* *Error Value: 'super' object has no attribute '__getitem__'
my class derive from (ObjectManager, BTreeFolder2, PropertyManager): I test : ** (ObjectManager, Folder PropertyManager):* **and got the same exception
the method of Sascha is working (This is a satisfaction). but i'm very interesting to understand the method proposed by Martijn.

Hi Stéphane.
Check out http://www.zope.org/Documentation/Books/ZDG/current/ObjectPublishing.stx
See the heading "Traversal methods" where this is explained.

Great, I should test this code tonight ! some more question : id don't understand the two different usage of __getitem__ and __bobo_traverse__. __bobo_traverse__ seems to be a way to control url walk and __getitem__ control the way attributs can be load by zope.
If I change the URL when I use __bobo_traverse__ it works, and if I change the way I'm searching attributs in zope object tree it works too. Is it correct ?
2008/3/26, Martijn Jacobs <martijn@fourdigits.nl <mailto:martijn@fourdigits.nl>>:
If you have a zope product you can do something like this indeed :
class MyContainer(Folder): """My Folderish Product"""
def mydoc_xls(self, REQUEST=None): """My new xls method""" return "My new xls method"
def __getitem__(self, key): """Check for mydoc.xls, then return mydoc_xls""" if key == 'mydoc.xls': return self.mydoc_xls return super(Folder, self).__getitem__(key)
Hi! Hey, Tres, could you point us to a web example or a web page with more information about that technique? I'm very interested on it and the technique that was introduced sometime ago about how to return a string as __bobo_traverse__ response but the example was uncompleted (for me at least)
This kind of information was very useful for many of us but there are no good tutorial or how-to
Thanks a lot!

Or add a '__getitem__' to your class that looks for that key and returns the right method.
