[Zope] Q: filtering search results by checkPermission?

Hi, I'm trying to filter a search results list to remove documents which the current user doesn't have permission to view. I wrote a python script which tries to do just that. I call checkPermission('View', x.absolute_url) for every element in a doFormSearch result list, but it doesn't quite work. What should I use instead of "x.absolute_url" to find the object of a search result? --Noel # list_viewable = filterCheckPermissions(list_search_results) # # usage: # <dtml-let results="filterCheckPermissions(doFormSearch(REQUEST=REQUEST))"> # # from AccessControl import getSecurityManager checkPermission = getSecurityManager().checkPermission; return filter(lambda x: checkPermission('View', x.absolute_url), list)
