determining if a item is a character
by Graham Chiu 11 Feb '00

11 Feb '00

I wish to prevent single character searches unless they are numeric. I'm trying this in my zsql code without much luck <dtml-if "_.len(_['sequence-item'])==1"> and _.find(_.letters,_['sequence-item'])>0"> do something here... </dtml-if> ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin

Zope.org Search Niggle
by Chris Withers 11 Feb '00

11 Feb '00

Nice to see that searching for 'Portal Tool Kit' now returns a superset of searching for 'Portal' ;-) How come if you ask to view a printable page of any search you do in Zope you get something like 1400 results returned? Hmmm.... Chris

Zope installation script
by Oleg Broytmann 11 Feb '00

11 Feb '00

Hello! Attached is a script I am using to install new Zope releases. Some things I still do manually - copying of old Producnts and Data.fs files. The script should be run with $PWD = Zope-src. The script can be run under any user that has rights to write to the Zope-src directory. When running the script generates a script root.sh, that should be run by root to complete installation. I assume that owner is root, and WWW server is running under GID www. The script can be easiliy modified for other conditions. Anyone bother to look? to test? to comment?

Syntax: Learning from JSP's problems
by Robb Shecter 11 Feb '00

11 Feb '00

Hi, I think I saw somewhere that a new / alternate syntax for Zope/DHTML is being thought about or worked on. If so, here's something that can give a push in (what I think is) the right direction: There's some dissatisfaction in the Java servlet community re: JSP (JavaServer Pages), and one of the big reasons is the syntax. This article compares JSP to a competing template language that does things (IMO) much better: http://www.servlets.com/soapbox/problems-jsp.html ...For me, the syntax of DHTML is the most difficult aspect of Zope, and is reminiscent of JSP. - Robb

FSSession and version locking
by Hung Jung Lu 11 Feb '00

11 Feb '00

Hi, I ran into problem with FSSession and Version locking. When the Version object is turned on, the FSSession is affected by it. Which means if one person is working on one version, no one else can work on the Zope site. (At this moment, I have a single FSSession object at the root of the Zope site.) regards, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

problem with ZCatalog
by Dyon Balding 11 Feb '00

11 Feb '00

Hi, I'm having some problems getting my ZCatalog to work. I have a number of objects in the catalog, which are indexed using a number of FieldIndex and TextIndex indexes. This seems to work, however I am having trouble with the TextIndex. It appears to only index words up until an occurrence of the word 'not', and ignores any words in the property after that. It seems weird that noone has noticed this before, so maybe I have made an error in my code but it seems unlikely. I am inheriting from ZCatalog and the FieldIndexes behave as expected, it's just the TextIndex that stuffs up. Any ideas? thanks -d -- Dyon Balding, email: dyon(a)adroitnet.com.au work: +613 98888522, mobile: +61 0414992604 Adroit Internet Solutions

Zope and IIS
by James W. Howe 11 Feb '00

11 Feb '00

I'm trying to get my Zope installation to work with IIS. I've read various items from the mailing lists and I've read the how-to's and I still can't get it to work correctly. The closest I've come is getting the Zope welcome screen. I've never been able to see any contents of my site. I think I've followed the process correctly. 1. I have a zope.pcgi file in my IIS scripts directory. 2. I have the pcgi-wrapper.exe file in this directory as well. 3. I've configured IIS to have a mapping between .pcgi and pcgi-wrapper.exe 4. I've reconfigured my zope startup to include a -p c:\inetpub\scripts\zope.pcgi parameter 5. I've modified by access file to just be of the following format: <domain>/<userid>: The domain is uppercase and the userid is how it was defined in the user manager. 6. I've set the permissions on the zope.pcgi file to disable anonymous but activated basic and challenge/response. 7. I've restarted Zope and IIS (several times) When I try to use access my site with http://foo.com/scripts/zope.pcgi I am prompted for a password, but I never authenticate. I eventually get a "You are not authorized to access this resource" traceback page (fails at line 551 in HTTPResponse.py) What am I missing? How can I debug this configuration? Assuming that I can make this work, I have a couple other configuration questions: 1. Is there a way to make a particular folder in Zope the default page for my web site? I want people to be able to go to http://foo.com and have that really access something like http://foo.com/RootName/StartingPoint. 2. How do you configure access to this site? I want to provide my customer with limited access to particular folders. Do they need to have an account in the NT Domain on which the server is running? If I want anybody to be able to access certain portions of the site for viewing only how do I configure Zope and IIS? In other words, I want to have one or more users with some sort of content control capability, but everyone else just sees a web site (no folders, no knowledge that this is Zope). I'm pretty sure I know how to do this if I just use ZServer, but I'm not sure what I need to do to configure this for IIS. I'm going out on a limb recommending that my company user Zope for a potentially key customer. I'm confident that the environment itself will support the customers needs, but I need to be able to show that the system can actually work in a production environment. Thanks for any and all help.

Let's do the Time Warp again!
by John Edstrom 11 Feb '00

11 Feb '00

How are the modification times of Zope objects reckoned? I was wondering how to set the last-modified field in the response. I have a folder with some objects and subfolders that will be displayed in text or dtml-tree formats. If I use "lynx -head" to look at the folder, I get the modification date of index_html. If I look at the 'page info' page in me navigator, it has no mod time info at all. If I print bobobase_modification_time in index_html, I get the mod time of the folder, the time an object was added to, or deleted from, the folder, or when a property was changed. Two questions: 1) I plan to scan the folder and use the mod time of the youngest object in the folder as the mod time of the overall folder object with REQUEST.setHeader('Last-Modified',max(datetimes[]). How do I get the mod time from objects in general? Bobobase_modification_time is a string, I'd like to get the value that bobobase_etcetera stringifies. 2) It seems that the ZServer response to HEAD requests involves some initiatives that are not taken with ordinary GET reqests to the same object. Is there any way to make it consistent with what I do for 1), or will it override my methods for reporting the mod time of my objects? je -- Urbane guerilla in the mist
