So it's kosher then to reimport the Zope module and use app() in a constructor method, Shane? I was always afraid it would do something horrible.

The way to get the root application object is to open a connection to the ZODB and get the 'Application' object from the list of root objects. There is an easy shortcut:

import Zope app = Zope.app()

app now refers to a *copy* of the root Application object.

Yeehaw, that worked! I was so close. :-)

When you're done modifying it and its descendants you have to commit or abort the transaction.

Do I need to commit or abort even if I don't make changes to the application object? The only thing I need it for is to get to the Control_Panel; I am instantiating ZClass instances in the constructor of a Python class, i.e.:

class MyClass:

def __init__(self, id, title=''): import Zope app = Zope.app()

ob = app.Control_Panel.Products.MyProduct.MyZClass('newId') ob.id = 'newId'

self._setObject('newId', ob)

# Do I need a get_transaction().abort() here? Will that not abort # the wrong transaction?

app._p_jar.close()

...

This gives you all kinds of benefits like undo and elimination of threading conflicts.

Good stuff. Thanks, Shane.
