Color names
by John Poltorak 29 Nov '04

29 Nov '04

Where do I find a list of color names which Zope recognises? I tried RGB.TXT from XFree86 but that was not definitive. I don't suppose there is a color wheel hidden away in ZMI anywhere is there... -- John

Product installation
by John Poltorak 29 Nov '04

29 Nov '04

As I understand it, all that is required to install a product in Zope is to extract the archive to the Products directory and restart Zope. This is what I have done in the past and then the product shows up under /Control_Panel/Products. For some reason this does not happen with PloneGuestbook on my installation of Zope 2.7.3 on Linux Redhat v7.3. Can anyone suggest why? Or where should I look to see any signs of problems? No relevant msgs are to be found in the logs. -- John

Proxy Support for External Editor
by Stefan Götz 29 Nov '04

29 Nov '04

Hi! People forced to use an HTTP proxy may find a slightly patched version of the External Editor helper app useful that supports proxies: http://ps.ri.uni-tuebingen.de/Members/goetzs/zopeedit.py/file_view The proxy name and port can be configured via an environment variable or configuration file option of the form "http_proxy = proxy.mydomain.com:3128" Cheers, Stefan

I was getting the same error when running from the test tab. As it turns out, I was running Zope 2.8.01a. Perhaps it was just a compatibility issue. I removed that and compiled Zope 2.7.3 and everything is working wonderfully now. Thanks all for the help. Tom

displaying view restricted and non-restricted objects together
by Tom Germaine 27 Nov '04

27 Nov '04

I am having a problem restricting view of ZClass objects in a subfolder with local roles defined when they are displayed alongside non-restricted objects. I am using LDAPUserFolder to restrict access to management screens, with authorization linked to Novell groups and passwords; this is working well. I am trying to use same authorization to restrict viewing of dtml documents in a subfolder with a local role defined identical to Novell group names; security is set so that view and view contents of the subfolder is for group members only. Authorization works but for one glaring problem: - when displaying all folders and subfolders contents (titles of dtml documents only) using dtml-tree as in: <dtml-tree (top-level folder id) branches_expr="objectValues(['Folder','(ZClass object)'])" sort=title> authorization is required to display ANY dtml document titles (because the restricted access document titles are also being displayed). What I would like is to have all titles displayed and authorization to view the restricted ones enforced only when trying to access them, because there are multiple subfolders in the tree, each with unique access restrictions. Is there a way to use dtml-tree to accomplish this? I have tried <dtml-tree...skip_authorization=1...> but this just removes the titles of the restricted documents from being displayed, and so makes accessibilty to them impossible. Maybe I should be trying to set the security on the individual dtml document view properties, but don't know what property to define and how to use it.

RE: [Zope] psyco

Sorry, I did a mistake, in SpeedPack, "monkey patching" is for CMF skins optimization... not ZPT (ZPT is optimized with psyco). -----Message d'origine----- De : zope-bounces(a)zope.org [mailto:zope-bounces@zope.org]De la part de Pascal Peregrina Envoyé : samedi 27 novembre 2004 17:56 À : zope(a)zope.org Objet : RE: [Zope] psyco Some people have made a product that use psyco and also do some "monkey patching" for ZPT optimizations. See http://sourceforge.net/project/showfiles.php?group_id=55262 : SpeedPack I have been using it for a while without any issues. It looks like trying to use psyco.optimize() or psyco.profile() in Zope startup scripts does not work. (I mean the Zope instance does not start correctly). So you have to psyco.bind() every class, or class method you want to speed up. Also, I discovered that you must not use psyco with publishable methods in products (this is if you develop your own Zope products). I mean any method that have REQUEST object in it's named parameters or that is supposed to get its parameters from the HTTP request params. If you psyco.bind() such a method, REQUEST (or params) are None. So for my products I psyco.bind() manually some classes methods, but not the whole class. This is just my own experience of it. I was not able to find documentation. In terms of results, the improvement are "visible", but I have no exact figures to give you. So I would say it's worth trying.
