Odd, even, it doesn't matter except for whether the first row is colored or not. By referring to sequence-odd twice, does it 'reset' it somehow? -----Original Message----- From: Paul Zwarts [mailto:paz@oratrix.com] Sent: Thursday, July 12, 2001 8:54 AM To: Schmidt, Allen J.; zope(a)zope.org Subject: RE: [Zope] Setting the correct bgcolor it TR tag Perhaps you are expecting sequence-index to start at 1 instead of 0? ALthough, it would make more sense that since you state sequence-odd twice, it should always evaluate the first one and always ignore the second. -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of Schmidt, Allen J.

Multiple selection property and Zcatalog
by Benoit DOMINIAK 12 Jul '01

12 Jul '01

Hi, I did a Zclass which has a property called "connection" which I want to be a multiple selection property. How can I access to the value of this property ? If I put <dtml-var connection> I get a list but I can't access to one of the item of the list in particular. I tryed connection[1]... but I only get a char : connection is a string !!! How to index this property in a Zcatalog ? I want to be able to find an instance by quering on one item of this property. PLEASE HELP... _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Setting the correct bgcolor it TR tag
by Gitte Wange 12 Jul '01

12 Jul '01

Hello, I am generating a list of objects with different BG color in the TR tag. The code I have now looks like this: <dtml-if sequence-odd> <TR class="MastHead"> <dtml-else> <TR BGCOLOR="#FFFFFF"> </dtml-if> Usually this works in a <dtml-in> sequence but ... We will one list objects that has metatype=Media Manager Show so therefor the code looks like this: <dtml-in "objectValues()" sort="getId" size="19" start=qs skip_unauthorized> <dtml-if expr="meta_type == 'Media Manager Show'"> <dtml-if sequence-odd> <TR class="MastHead"> <dtml-else> <TR BGCOLOR="#FFFFFF"> </dtml-if> Since it only some of the object values that are used I cannot be sure that the bg color of the row-items is set corectly (right now they are all blue). Therefor I thought if I could move the type-check into the <dtml-in> request. Anywho knows how to do this ??

I always forget..... -----Original Message----- From: Paul Zwarts [mailto:paz@oratrix.com] Sent: Thursday, July 12, 2001 2:08 PM To: Gitte Wange Subject: RE: [Zope] Setting the correct bgcolor it TR tag Hi Gitte, I would suggest you rethink your classing system first. You are heading for alot of code writing in this method. Why not create classes such as: MediaManager CurrentItem OddItem EvenItem and so on covering ALL of the objectTypes you use. That way you can use: <dtml-in "objectValues()" sort="getId" size="19" start=qs skip_unauthorized> <TR class="<dtml-var "ObjName.objectProperty(propName)">"> </dtml-if> or something like that. Then for alternating colors, you use a combination of your and mine: <dtml-in "objectValues()" sort="getId" size="19" start=qs skip_unauthorized> <TR class=" <dtml-if "objectName==_['sequence-item']"> <dtml-var "ObjName.objectProperty(propName)"> <dtml-elif sequence-even> EvenItem <dtml-else> OddItem </dtml-if>"> </dtml-in> Although I dont know your datamodel, this works quite well. Just remove the tabs and returns to make the outputted HTML look more sane.

RE: [Zope] Re: WHY ? -- Performace in serving large media filesfrom ZODB vs from external file system
by Sedat Yilmazer 12 Jul '01

12 Jul '01

Hi Zopers In most of the systems ( specially where we have a server and performanace requirements) we have high end systems with fast disk access. In such system the problem most of the time is the CPU power/RAM/Internet Connection Speeds. If you have a system with a 2-8Mbps your basic bottleneck is at the CPU and RAM side, NOT at the Disc IO side. Lets assume that the total response time is setting up the client/server connection + (How is it in ZServer forks? ) request processing + finding the object in ZODB + Reading the object from ZODB + writing the data to temp file + pushing the file to client In this picture writting the file once more to the file system should not be a big part of the picture. In most systems IO is initiated by the CPU and completed by the hardware (DMA). If your channel to HD can not cope with that you must have the fastest Internet connection on the plannet. So as the last point. I would never ever giveup a consistent implementation if the performance inrease is less then %100. HW is so cheap that spending some days to get thing working may cost you alot more.

Sure, but it may well do, if you have a really fast network or access it locally. The most efficient solution: read file in chunks and stream it onto the TCP connection. ZServer's solution: read the file in chunks, write to a temporary file. Read the temporary file in chunks and stream it onto the TCP connection. Additional overhead: Reading and writing the file once.

EventFolder 1.3 problem
by Georg Rellensmann 12 Jul '01

12 Jul '01

Hi, I installed EventFolder 1.3 on a ZOPE 2.3.3 site. When I try to post a new event a password-message pops up and I cannot add the event: (Object: EventDocument_add) Unauthorized: title I looked at the EventFolder FAQ, but all _add methods do have the manager proxy role. I tried to add an event as a manager from the managing screens as well as a "user" of the site. What is going wrong? All comments are highly appreciated! Regards, georg
