How did you do that? I managed it the following way: -------------- snip --------------- from zope.app.appsetup.interfaces import IDatabaseOpenedWithRootEvent from zope.app.appsetup.bootstrap import getInformationFromEvent @adapter(IDatabaseOpenedWithRootEvent) def addFoobar(event): db, connection, root, root_folder = getInformationFromEvent(event) if 'swarmfinder' not in root_folder: root_folder['foobar'] = Foobar() ------------- snip ---------------- What I dislike here is that there that I use the function "getInformationFromEvent", which is already called in the function where in the event is triggered; Especially it does a "database.open()", which is maybe not a good idea as the database is already opened. Is there a cleaner way?
