[Zope-dev] Recursive folders from Python

[Phil Harris]

Try something like (taken from my own code, so it works for me, caveta
emptor):

def mkcontext(self,context=None):
    global default_dd
    if not context:
        return 'EH!!!!!'
    c=string.split(context,'/')
    newself=self
    for a in c:
        try:

newself.manage_addFolder(a,createPublic=0,createUserF=0,REQUEST=getattr(self
,'REQUEST',None))
        except:
            pass
        newself=getattr(newself,a) ## this is the relevant line
    newself.manage_addLocalRoles(c[-1],['Manager'])
    try:
        newself.manage_addDTMLMethod('index_html','Start
Page',file=default_dd)
    except:
        pass

This func takes a slash separated list of folders (actually a NDS context
like 'dacs/media/stf/wmlph' and creates the folder hierarchy.

It's probably overkill for what you want but the relevant line is the
getattr one (as marked).
