DTML vs ZTP
by Ian Nunn 15 Dec '04

15 Dec '04

I'm a third of the way through the Zope Book and understand the difference as it is written. As you can appreciate, in learning a new technology, what is missing is the experience that would guide your focus. What I would like is an idea of how real world developers use these in the following senses. Do you use one exclusively (in conjunction with Python)? Do you use primarily one or the other? Do you use both roughly equally? Are there classes of applications where you have found one is preferred? Your advice would be welcome.

Getting title attribute given objectid
by Cliff Fogle 15 Dec '04

15 Dec '04

First off...I just started playing with Zope today... This seems like it should be easy, but I've been searching google and the archives all day to no avail. I have an object ID and would like to display the object title as the content of a drop down menu. As it is now I can only display the ID: </select> <select name="querytype"> <span tal:define="ids root/Database/querytype/objectIds" tal:repeat="id ids" tal:omit-tag=""> <option tal:attributes="value id" tal:content="id">Item from sql method</option> </span> </select> What I want though is for the only the value to be the ID and the content to be the title. So something like this (which does not work): </select> <select name="querytype"> <span tal:define="ids root/Database/querytype/objectIds" tal:repeat="id ids" tal:omit-tag=""> <option tal:attributes="value id" tal:content="id/title">Item from sql method</option> </span> </select> I'm going to go get a good book on Zope and read it tonight. But if that doesn't help can anyone here help me out? Thanks Cliff Fogle Network Engineer Ofoto, Inc.

Filling a metal slot which name is known only at run time
by Martin Aspeli 14 Dec '04

14 Dec '04

Hi, I am writing a kind of generic templating system. The details are not so important, but essentially, I need developers to be able to write page templates with slots, which end users can fill with various content via a tool I'm writing. Basically, I need to be able to get the list of all slots in a macro (which I can by traversing the contents of 'template.macros') and then to generate a metal:fill-slot statement for each one. However, the problem is that metal:fill-slot seems only to accept a static string as the slot name. I need to be able to generate the fill-slot statement at run-time, essentially something like: metal:fill-slot="python:here.getSlotToFill ()" though that doesn't work, because it doesn't evaulate the python: statement, taking it instead as a string (which is an invalid slot name). Can this be done? Thanks, Mart -- "Life is both a major and a minor key" -- Travis, Side

Caching zope pages
by John Poltorak 14 Dec '04

14 Dec '04

I have been trying to set up Squid as an httpd accelerator for Zope with the idea of speeding up load times, especially for Plone. Unfortunately Squid appears to simply redirect any requests rather than serving them from cache. Is there anything I can do within Zope to allow pages to be cached? Or have I overlooked a Squid setting? -- John

Return image from Python Script
by Simon Forster 14 Dec '04

14 Dec '04

How do I return an actual image file from within a Python Script? return context.restrictedTraverse('/LDML/images/ldml.gif') Gives me: <img src="http://127.0.0.1:8080/LDML/images/ldml.gif" alt="" title="" height="120" width="120" border="0" /> But what I actually want to do is return the file itself. Think Python Script as symbolic link. Sorry, must be v. easy but I've been thrashing around on various sites for about an hour now and I'm getting no closer. TIA Simon Forster

RE: [Zope] Running a process in the background

About having some background thread running, and interacting with it, you should have a look at this products source code (very few files) : + TimerService 0.2 + ZopeScheduler 0.2 from http://dev.legco.biz/downloads Pascal -----Message d'origine----- De : zope-bounces(a)zope.org [mailto:zope-bounces@zope.org]De la part de Will Smith Envoyé : mardi 14 décembre 2004 16:15 À : zope(a)zope.org Objet : [Zope] Running a process in the background I currently have a zope product that can download files from another server. The only problem is that while the file/files are downloading the web client is stuck looking at nothing. My goal is for the user to be able to click the "do download" button. At this point the user is given a status page that says "download running" and then be able to continue using the site. Since I know the filesize before the download starts I would love to able to do a status page "download 58%". Another caviate to this process, is that it needs to be able to run on Linux and Windows. I realize this is really a python specific question, but was hoping that someone has implemented something similar on thier zope site.

SOAP support in Zope
by Richard Jones 14 Dec '04

14 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've looked around for SOAP support in Zope, and all I seem to be able to find are either patches from way back in 2000 to implement it (with no followup that I can find), statements around that time from ZC saying it's implemented or much more recent statements (January this year) saying that Zope supports SOAP (in response to a query similar to mine): "Well, you can call any Zope method with SOAP as far as I have tried (from Flash that is). Works fine." (http://mail.zope.org/pipermail/zope/2004-January/145483.html) So I just tried to invoke some simple Zope methods with SOAPpy, and got "error in processing external entity reference" even for a simple python script "return 'hello'" (which I know from experience works from XML-RPC clients). So, is SOAP supported? If yes, is there any documentation to tell me *how* it is supported?
