[Zope] objectValues sorting in pythonscripts ?

[Phil Harris]

Geir,

This is something I've just hacked from a longer piece of code, works for
me, ymmv

def cmpfunc(a,b):
    a=3Da[1].aq_explicit
    b=3Db[1].aq_explicit
    ast=3Dgetattr(a,'precedence',None)
    if not ast:
        ast=3Dgetattr(a,'short_title',None)
    if not ast:
        ast=3Da.title_or_id()
    bst=3Dgetattr(b,'precedence',None)
    if not ast:
        bst=3Dgetattr(b,'short_title',None)
    if not bst:
        bst=3Db.title_or_id()

    if ast<bst:
        return -1
    elif ast>bst:
        return 1
    else:
        return 0

def sorted_items(self):
    items=3Dself.objectItems()
    # This is laziness on my part.
    # some of the objects don't have certain properties and I can't be
bothered checking ;)
    try:
        items.sort(cmpfunc)
    except:
        pass
    return items

hth
