[Zope] client argument to python function calls?

27 Nov 2000

      I'm trying to emulate some DTML methods with python code in my (python) product.

Let's say I have two Python classes, one named Foo, the other Bar.  Something like this:

class Foo(Folder.Folder, Persistent, Implicit):
    meta_type = "Foo"

    def magic(self, client=None):
        "magic method!"

        if client == None:
            client = self

        return client.magic_word

class Bar(Folder.Folder, Persistent, Implicit):
    meta_type = "Bar"

    def __init__(self, id):
        self.id = id
        self.magic_word = 'Alacazam!"

Now I create a structure like this in Zope:

/
    foo    (instance of the Foo class)
    bar    (instance of the Bar class)

Now if I goto /bar/foo/magic, I see the magic word.  However, I would also like to use /foo/bar/magic, and also receive the magic word.  This latter case doesn't work, the magic_word isn't set.

In fact, the "client" argument is never anything but None.

This is a facet of Zope I still don't quite understand...

Thanks,
-Randy
