Duh, well yes that's a start ... But how would I make sure I do this for all threads? Running this once would load/cache the objects only in the thread in ran in. That's the hard part I think :) J.F. -----Original Message----- From: Jean Jordaan [mailto:jean@upfrontsystems.co.za] Sent: May 28, 2004 8:18 AM To: Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca Cc: zope(a)zope.org Subject: Re: [Zope] Help!

Eg. for p in context.Catalog(meta_type="whatever"): p.getObject() They should now all be in memory.

int's as keys for dictionaries
by Bryce Harrington 31 May '04

31 May '04

I'm running into an issue I don't understand when using ints as keys in hashes. <dtml-let d_test_parameter="{'1':'a', '2':'b'}"> We set id="1" <dtml-let id="1"> This works: <dtml-var "d_test_parameter.get('1')"> But this doesn't: <dtml-var "d_test_parameter.get(id)"> Nor does this: <dtml-var "d_test_parameter.get('id')"> </dtml-let> Now set id="'1'" <dtml-let id="'1'"> This works: <dtml-var "d_test_parameter.get('1')"> Now this works: <dtml-var "d_test_parameter.get(id)"> This still doesn't: <dtml-var "d_test_parameter.get('id')"> </dtml-let> </dtml-let> How can we force id to be interpreted as a string for the dictionary key in the first case? Thanks, Bryce

Python script to modify the permision on photos
by kbond 31 May '04

31 May '04

Hello, I have a very basic script to write and I facing the some difficulties to understand the Zope Api. My problem is the following : I have tones of photo in several PhotoAlbums that do not have the correct permision. I want to allow only a specific role to view those photos. I found out how to do it in interactive mode, using (instance:8080/manage), but with this method is way too long so I have decided to write a script that will recursively change the permision on all the photo in a branch of my web site tree. So far I already play around in "spe" and get the following: ++++++++++++++++++++++module++++++++++++++++++++++++++ #! /usr/bin/env python import os, sys sys.path.append("/usr/lib/zope/lib/python") import Zope Zope.configure("/home/yml/myZopeInstances/sitePerso/etc/zope.conf") app = Zope.app() #app.sitePerso.Albums.Photo_Album_la.get("Photo_Album.Apt") ------------------In Shell------------------------------------------------------------- appart = app.sitePerso.Albums.Photo_Album_la.get("Photo_Album.Apt") albumsChantier = appart.get("Photo_Album.chantier") chant3 = albumsChantier.get("Photo_Album.chan3") >>>chant3.objectItems() > [('Chantier 052.jpg', <Photo at > /sitePerso/Albums/Photo_Album_la/Photo_Album.Apt/Photo_Album.chantier/Photo_Album.chan3/Chantier > 052.jpg>), ('Chantier 053.jpg', <Photo at > /sitePerso/Albums/Photo_Album_la/Photo_Album.Apt/Photo_Album.chantier/Photo_Album.chan3/Chantier > 053.jpg>), ... cut.... ] photo = chant3.get('Chantier 053.jpg') photo.manage_permission("View", "MyRole",1) I have several questions concerning this code: How can I check, by script, that I have done a modification on the permission? Please I am stuck And I do not know where to search I have googled the whole evening without any success. Thank you for your help.

ExternalEditor problem
by Des Dougan 31 May '04

31 May '04

I'm setting up Plone 2, and have been trying to configure the ExternalEditor helper application on my SuSE 9 desktop. When I click on an edit link, a temporary file is created on the PC, but the helper app does not open the editor. However, when I run zopeedit.py on the command line, I get a "FATAL ERROR: 'url'" message, and the file I entered as the parameter is deleted. I've tried with several different file types, and with my own ID and the root user, and see the same result each time. The traceback file created has the word "None" in it - nothing else. Can anyone shed any light on why this is failing?

[Ann] AdvancedQuery 0.3
by Dieter Maurer 30 May '04

30 May '04

AdvancedQuery is a Zope product for flexible queries against "ZCatalog" or "CatalogTool". Queries can be arbitrarily combined with "and", "or" and "not". All index types are almost fully supported (exception: relevance sorting of TextIndexes). AdvancedQuery supports efficient incremental (lazy) multi-level sorting via FieldIndexes. This means, you can sort via e.g. "sort_on=(('Date','desc'), 'portal_type', 'id')". For large result sets, sorting is performed incrementally, only as far as you access the result. This can drastically speed up sorting time. AdvancedQuery is especially efficient for "ManagableIndex"es (see: <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex>). New in version 0.3: * uses for CMF's "CatalogTool" an index ValidityRange (assumed to be a Managable RangeIndex) in preference of CMF's effective and expires indexes which can significantly improve query speed More information and download: <http://www.dieter.handshake.de/pyprojects/zope#AdvancedQuery> Note: This may be the last version with its current open source unrestricted use license. I consider whether I will expressly forbid the use of my software by institutions of the European Union (Councel of Ministers, Commission, Parliament, ...). This is in protest against a recent decision of the Councel to make software patentable. This decision ignores a Parliament vote that pleaded to keep logic (algorithms, business rules) un-patentable. -- Dieter

[Ann] ManagableIndex 0.5
by Dieter Maurer 30 May '04

30 May '04

ManagableIndex is a flexible indexing framework. It comes with managable field, keyword and efficient range indexes. Via the management interface, you can for example configure * how to combine values to be indexed from various attributes * how to normalize terms, e.g. for case insensitive searches * to ignore stop terms to keep your indexes small * to convert terms into an efficient form This is how ManagableIndex supports efficient "DateTime" and "DateIndexes" * how to handle acquisition and calling of values New in version 0.5: * "RangeIndex" now efficiently supports improper ranges, i.e. ranges with at least one unrestricted boundary, * a "RangeIndex" can now be used as a (partial) plugin replacement for CMF's "effective" and "expires" indexes. I expect that such a replacement will speed up most CMF searches. More information and download: <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex> Note: This may be the last version with its current open source unrestricted use license.

TAL and Zope Security
by patrick sullivan 30 May '04

30 May '04

I am having some problems comprehending a security issue with zope and page templates. I have a folder protected by exUserFolder, and that folder contains another folder where my site is sitting. I have a page macro that all other pages use, so i just need to fill in slots of content throughtout the site. i want to make a page available to Anonymous users. But this page template contains calls to z sql methods, the page macro, some images, etc etc etc. I changed my Security permissions on this page tempalte for Anon to view and access object contents but i am still getting the authentication popup. That didn't work. So I gave anonymous everything in the security tab, and still no joy. Do I have to allow for Anon on everything that this template uses to fill its slot? Like every image, every z sql method, the page macros, and everything else? Thanks, Patrick __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!
