Re: [Zope] rendering the contents of ..
I think something like this is what you're looking for:
===
from Products.PythonScripts.standard import html_quote
import random
request = container.REQUEST
RESPONSE = request.RESPONSE
q = container.quotes.objectValues('File')
return random.choice(q)
===
cheers
