Sorry I wasn't clear enough. The Singleton is a design pattern from the
Gang of Four book that fits this situation well. It is a class that is
meant to control access to the one and only instance of a global
variable. I was just using that as a frame of reference, though; Zope has
no such class for the Application object, or I wouldn't be writing this
message.
I just need some way of getting at the one and only Application object at
run-time. Something like:
from Globals import app
myOb = app.Control_Panel.Products.MyProduct.MyZClass('foo')
...
Given a reference to an object in the ZODB, I can do this via:
app = self.getPhysicalRoot()
myOb = app.Control_Panel.Products.MyProduct.MyZClass('foo')
But, this does not work from methods like __init__, or __setstate__, where
we do not have a physical location in the ZODB, yet.
I just need a reference to the app object. I know the answer has to be
simple, but I can't find it.
