This looks like the "cDocumentTemplate/Acquisition" bug (see the locator (URL:http://classic.zope.org:8080/Locator) for a description). The problem usually occurs in the context of a <dtml-with folder> You can work around it by using <dtml-with "PARENTS[0].folder"> instead. Dieter

Hi Turhan, Welcome to the Zope community! Turhan Arun writes: > Now my problem is as > follows > I have to use > Zope Application Server on SUN > iPlanet Web Server > Oracle 8.1.6 Database server > Would you help me about configuring these? I am having problems and you are > my only source. You have 2 subproblems: interfacing Zope with iPlanet and interfacing Zope with Oracle 8.1.6. 1. Unfortunately, I do not know iPlanet. You may search "zope.org" for "iPlanet" (maybe, you find a HowTo). There is also a searchable archive of this mailing list at NIP (to be found via "zope.org -> Resources -> Mailing Lists"). If you are unlucky, you must explore a bit yourself. "doc/WEBSERVERS.txt" (a file in the Zope distribution) is a good starting point. Although, it mainly speaks about Apache (and does not mention iPlanet), the "pcgi" connection will work with any webserver that supports CGI. It will work with "iPlanet". There might be some problems with the propagation of authentication information. You may decide to let iPlanet do all authentication and let Zope unprotected or you might need to learn how to configure iPlanet to pass authentication information. You may want to screen the iPlanet documentation, whether it supports proxy mode. In this mode, iPlanet would relay (some) requests to another web server (Zope in your case). This would be more efficient than "pcgi". 2. We use Zope with Oracle 8.1.6. We use DC's DCOracle and ZOracleDA (latest version! it has a beta in its version number!). It works satisfactory with the exception of LOB support. DC is working on improvements but the project is not externally funded, progress seems to be slow. Some days ago, someone in the list has reported a package that can be used to work around the LOB restrictions (if you know the LOB type). Search the list archive to locate the article (search for "DCOracle and BLOB"). Dieter

In earlier Zope versions, most methods of "DateTime" instances used local time, but "strftime" used GMT. As I understand it, this has been changed in Zope 2.2. At least, Brian asked in the list, whether it should be changed and got some positive feedback. Dieter

Hi Zope, I wondered, whether it's possible and sensible to have php-Pages in Zope sites ... any thoughts and comments on this matter? Cheers, Vince ''' ô¿ô -

You may get more than 3 races? In this case, you could use: <dtml-in .... sort=closingdate reverse>  <dtml-if "closingdate > ZopeTime() and _.getitem('sequence-number') <= 3"> .... your presentation code .... </dtml-if> </dtml-in> This will give you the list sorted with decreasing closingdate. If you want a list sorted with increasing closingdate, you could use: <dtml-in .... sort=closingdate> <dtml-if "closingdate > ZopeTime() and (_.getitem('sequence-length') - _.getitem('sequence-index')) <=3"> .... your presentation code .... </dtml-if> </dtml-in> For more details, look at the variable list defined inside <dtml-in>.

Hi, Don't know. :-) How won't Zope start? What does it do? Just return and not spit an error? Let's take this to the Zope mail list if you don't mind (I've cc'ed it). ----- Original Message ----- From: Rudd-O DragonFear To: DC Support List Cc: support(a)digicool.com Sent: Monday, October 30, 2000 10:21 AM Subject: [Support] ZSybaseDA 2.00b2 Hey, I've been having some kind of problems with this DA. Compiling and loading (importing) sy_occ in python works perfectly. But zope won't start and won't say anything in the console or in the logs. what could it be? thanks in advance, Manuel

How to display PDF files
by Alan Johnston 30 Oct '00

30 Oct '00

I installed Zope for purposes of evaluation last week. I've been through the tutorial so I have minimal knowledge. One (apparently simple) thing I cannot find a way to do is link to a PDF file. I believe that everything ZServer serves up must come from the Zope Object Database (right? wrong?). At any rate, how do you get ZServer to send a 'raw' PDF file to the browser so that the browser's Acrobat plug-in can display it? I tried creating 'File' and 'Image' objects. That's obviously not it. Forgive me, for I fear this is a dumb question ... but I just can't find the answer. Thanks, Alan

<dtml-var > reload ?
by Spicklemire, Jerry 30 Oct '00

30 Oct '00

Luc wonders: > is it possible to reload only a <dtml-var value> without reloading an = > entire page ??????????? > if yes, how?? The short answer is no. That is, unless you are willing to set up some sort of Java RMI process, or other complex solution, and pray that your audience has downloaded and enable, or at least hasn't turned off the required services. On the other hand, there may be a simple way to meet your needs. You could borrow an idea from those annoying Web Sites that pop up "little windows" in addition to the main page that you thought you were linking to. By separating the item you want to be refreshed so that it displays in its own browser window, and setting a metatag in that page specifying a short refresh period, the contents of that window will be reloaded independent of the "main" window. Later, Jerry S.
