[Zope] Zope Object Contexts and Acquisition

[Peter Sabaini]

does that do what you want to do?


# pyscript listRoot
rootPath = context.rootPath
root = container.restrictedTraverse(rootPath)
objects = root.objectValues(['Folder'])
return objects


where rootPath is a property i've set on my root folder, with a value 
of eg. '/site1' or '/'
