[Zope-it] Metodi esterni

[Aldo Bergamini]

Avete presente la API di Zope dell'appendice B dello Zope Book=3F

Oggi mi sono lanciato nel tentativo di usare il methodo
unrestrictedTraverse (nella release 2.5 =E8 a pagina 312).

Ora giustamente il server Zope mi ha mandato a quel paese perch=E8 il primo
tentativo lo ho fatto da uno script Zope via ZMI.

Ok, devo usare un metodo esterno.

Solo che non so come/da dove importare il metodo in questione. 

Il seguente sorgente:

>import ObjectManagerItem
>
>
>def getActiveCentres(StudyURL):
>   =09return ObjectManagerItem.unrestr
ictedTraverse(StudyURL).objectValues(('Folder'))

genera il seguente errore.

Ho guardato sui libri che ho, ma non ho cavato alcunch=E8 ... Dove posso
trovare una lista di metodi/oggetti di utilit=E0 da importare in propri
script esterni=3F
