Top Ten of most visited objects
by Jens Wolk 04 Aug '02

04 Aug '02

Salut everybody, I would like to present the visitors of my site a Top Ten (Top 20 or whatever) of the most frequently visited objects. Is there already a solution floating around in the Zope community? (Would like to avoide re-inventing the wheel.) Taking FSCounter (or any generic counter for that matter), the product I need should: - count the hits on a per object basis - count the hits on a per day (or even hour?) basis - be configurable in respect to what time range goes into the ranking (hits during the last x days) - be configurable in respect to what objects are listed Any hints to existing solutions are very welcome. Yours. Jens

unicode and forms
by Kristjan Sander 04 Aug '02

04 Aug '02

Hello I need to have forms in a utf8 webpage and I am currently having trouble with it. I need to decode unicode values from the forms to "normal" strings but I have not found out how to. In IRC, someone suggested that Zope should have unicode support and there indeed is a doc about it in Zope.org ( http://www. zope.org/Members/htrd/wstring/Unicode0.6Readme.txt ). But the same person said that it was probably integrated into Zope 2.6 which is in alpha right now and not 2.5.*. Could someone say, what is the current state of the utf support project? Is it integrated into Zope 2.5.*? Could someone provide any dtml code examples for a utf8-encoded form which is understandable to Zope? I would be thankful if you answered to my private address as well. Thanks in advance, Kristjan

adding user problems
by Dave Banning 04 Aug '02

04 Aug '02

I am having a problem adding a user only to a specific folder. I want the user to have control -only- over that folder so that is the only place where I have entered her. If you are familiar with the example guestbook, I want them to be able to simply delete entries. I have address here in the guestbook folder only, and with "manage" priviliges. I restarted zope from the browser, and then quit the browser and restarted it. What am I missing? __________________________________________________ Do You Yahoo!? Yahoo!

Report generation suggestions!
by Derek Basch 03 Aug '02

03 Aug '02

Hi, I need to generate reports from data stored on an SQL server that can be accessed via the web(zope). So far I have found ReportLab: http://sourceforge.net/projects/reportlab/ does anyone know of any other options. ohh yeah, a permissive license is preferred. Thanks, Derek T Basch __________________________________________________ Do You Yahoo!? Yahoo! Health - Feel better, live better http://health.yahoo.com

dtml-call behaviour
by gnotari＠linkgroup.it 03 Aug '02

03 Aug '02

I verified a strange behaviour of the dtml-call tag. As it seems, dtml-call'ing an inexistent method wouldn't produce any error, i.e. <dtml-call bogus> would fail to produce any output or exception. On the other hand, calling <dtml-call expr="bogus"> or <dtml-call expr="bogus()"> would indeed cause an exception -- bogus method doesn't exist, of course -- and can be caught be a dtml-try clause. I'm puzzled, ZopeBook says that dtml-call behaves the same way than dtml-var, but it's not true: dtml-var failes with both syntaxes, when the argument is inexistent. Sounds like some kind of bug. Or is it a "feature"? :-) ciao Guido

CMF Question - Is it possible to have Catalog-Aware folderish product?
by Steve Nicholson 03 Aug '02

03 Aug '02

I have been trying to create a folderish cmf product which is catalog aware without much luck. Is it possible to do? The new class inherits another folderish product class along with, PortalFolder, PortalContent, DefaultDublinCoreImpl. I have not been able to make the folderish product catalog aware with any of these parent classes in any order. I have also tried skinnedFolder. PortalContent seems to remove the folderish behavour depending on where it is in the "class( parent classes ):" line up. I thought PortalFolder was the answer but that hasn't helped either. What I would like to do, is be able to have new folderish instances catalog automatically when any copy/cut/paste or delete action is done. Any ideas or help on where I am going wrong would be much appreciated. (Running zope 2.5.1 / python 2.1.3 / win2000) Thanks Steve.

Re: [Zope] problem in using Zcatalog : Help needed
by Hamzat Kamal 03 Aug '02

Hi All, I have this problem in using ZCatalog. I have the Zcatalog and the folders that contained the DTML Documents in the root. What surprise me was that it shows the absolute url when I did not include _.getitem(mm,1) but display Nothing when included. Also I will like to know how to use pathindex just like the way i used id to limit results to those DTML Documents that have the same id and pathindex. <dtml-call "REQUEST.set('mm', ZopeTime().toZone('GMT+1').strftime('%d%m%y'))"> <ul> <dtml-in "Zcat_Index_1_Dtml_Doc(id=mm)"> <dtml-var expr="_.getitem(mm,1)[0:400]">... <br> <li> <a href="&dtml-absolute_url;"> More </a> </li> </dtml-in> </ul> Thanks. ===== Hamzat kamaldeen Ishola Dnet Systems Limited. 223 Ikorodu Road, Lagos.

In setting up the new site I wrote a configuration program that moves in and installs all the various products repeatably so I have a stable base. The ZClass portion ot the ZDiscussions (the zexp file) even gets copied into import for ease of installation. Just to be sure, I repeated the export process and everything worked. Such Heissenbugs bother me. I'm guessing that I may have mistyped one of the names or something. Anyhow, for the moment all is well. Thanks/

ZClass proxy roles - don't work?
by Wade Leftwich 03 Aug '02

03 Aug '02

I have a Product that contains several nested ZClasses. I'm trying to allow an anonymous user (actually a Xron object) to call a method on an inner class that will modify some object attributes. I have given the method a proxy role of Manager, but calling it still raises a login prompt. If I don't log in, I get 'not authorized to manage_changeProperties'. Any advice appreciated. (Anticipating one form of advice; yes, I really wish I had written the thing as a Python Product, and I'm trying to rewrite it properly in my Copious Free Time, and I'm never going to put a ZClass in production again.) Thanks -- Wade Leftwich Ithaca, NY
