[Zope] Python script calling environment

[Chris McDonough]

The script is finding the "actions" folder in "activity" instead of
finding it at the root (but you probably guessed that already).  There
would be a huge number of namespaces to search if Zope "kept going"
when it failed to find "action1" in "activity.actions" which would
slow down attribute access tremendously, which is why it doesn't find
"actions.action_1".

Try something like this to search both namespaces:

name_to_find = 'action_1'
actions = getattr(container, 'actions')
if not hasattr(actions, name_to_find):
    actions = context.restrictedTraverse('/actions')

action = getattr(actions, name_to_find)
action()
