CMF Creator Issues

Problem that this page attempts to solve: when a manager joins other people into a CMF, the new folder and index_html become owned by the manager which makes searches showing owners of such document appear to be authored by manager

Creator is a method that returns the owner of an object in CMF

Several people have posted ways to change the ownership of an object in zope (and thus in CMF) by using an external method. I called mine chown:

  def set_owner(self,user='bruno'): 
    """ change Creator """
    try:
      try:
        acl_users=getattr(self,'acl_users')
        user = acl_users.getUser(user).__of__(acl_users)
      except:
        return "%s not in acl_user folder"%user
      try:
        self.changeOwnership(user=user,recursive=1)
        return "done by "%self.Creator()
      except: return "perhaps it did or did not change %s  (check)"%user
    except: return "something not right %s"%user

usage: URL/CMF_Document_name/chown?user=whoever or as part of a python script that systematically changes ownership of Members folders to be the same as the id of the corresponding folder:

 print "<html>"
 for I in context.Members.objectIds():
   print "<li>"
   try:
       print context.Members[I].chown(context.rec.REC.Members[I],user=I)
   except StandardError,msg: print "<u>%s</u> %s"%(I,msg)
   try: print "%s <i>%s</i>   "%(I,context.Members[I].index_html.Creator())
   except: print "no index for %s"%I
 return printed

The above could be shortened to 3 lines. The problem I have is that some users are in the acl_user folder in the CMF and others in acquired earlier acl_user folders . I am not totally pleased with this program since it returns false negative results even though it does the job correctly but only for those who have an entry in the immediate acl_user folder.
Another issue is that CMF Documents seem to cook in the Creator so that unless one re-edits and saves a CMF Document, it appears to still have the old owner.
