Howdy, Yes, you can call another object outside your "tree". Example: lets say you have /folder1/folder1a/item1 and /folder2/item2 and you want to access item2 from item1 in dtml you need to put item2 into the context: <dtml-with "folder2.item2"> <p> This puts item2 from folder2 into context... any dtml-var calls will first be applied to item2 until the closing with tag </p> title of item2 = <dtml-var title> </dtml-with> with the "folder2.item2" Zope starts walking up the tree until it finds folder2 then walks down to find item2 hope this helps Tom "Vincent Stoessel" wrote: > > Hello All, > I have starting testing Zope as a potential > CMS for some production websites.

Strange SiteAccess behavior
by Itai Tavor 17 Jan '01

17 Jan '01

Hi, I got Zope 2.3b1 running on port 8080 at 10.0.1.20, a SiteRoot in /MySite with base='http://10.0.1.21/' and path='/', and the following Apache directives: Listen 10.0.1.21:80 <VirtualHost 10.0.1.21> ServerName MySite ProxyPass / http://10.0.1.20:8080/MySite/ ProxyPassReverse / http://10.0.1.20:8080/MySite/ ProxyPass /misc_ http://10.0.1.20:8080/misc_ ProxyPass /p_ http://10.0.1.20:8080/p_ </VirtualHost> The problem is that the SiteRoot affects the whole Zope site, not just things inside MySite. http://10.0.1.20:8080/ returns index_html from the top of Zope, but http://10.0.1.20:8080/manage returns the content of MySite instead of the top directory. What's going on here? How can a SiteRoot affect content above itself? -- Itai Tavor "Je sautille, donc je suis."

Curious DTML question
by Nick McDowell 17 Jan '01

17 Jan '01

Hi, I have a quick question regarding the "<dtml-with>" tag. I call a dtml method (that formats content into a HTML template) called myHTMLtemplate. This method is in another folder, called templates, and when I call it like - <dtml-with templates> <dtml-var myHTMLtemplate> </dtml-with> .......everything works correctly and my HTML page is rendered properly with graphics etc. However I initially tried to execute the method via the following (slightly less keyboard action) - <dtml-var expr="templates.myHTMLtemplate"> .......this results in the HTML template being displayed in plain text format i.e. the HTML is not rendered and all the tags are visible. I also tried calling - <dtml-var expr="templates.myHTMLtemplate()"> .......which was worse as it resulted in errors relating to Zope's inability to "locate" dtrml methods called within the "myHTMLtemplate" method.. The documentation I have been reading suggest that the first two commands in my example are equal, and thus should generate the same result, although in my case this is clearly not so. If anyone could please enlighten me on what's occurring or what mistakes I'm making, if any, I would greatly appreciate it. Cheers Nick

Strange behavior of document_src
by Sergio Fogel 17 Jan '01

17 Jan '01

I want to display the source of a DTML document inside a textarea (as in Zope's DTML editing screen). If I do: <dtml-var "doc.document_src()" > It works OK, but if I try <dtml-var "_['doc'].document_src()" > it tries to evaluate doc, and gives me an error (some of the vars are not defined in this context). Am I missing something? Sergio Sergio Fogel

In desparate need of some help
by alankirk 16 Jan '01

Hi there, i am new to zope and i'm in need of some help. I'm using zope as part of my final year project for university. I am using zope with a database i've constructed using MySQL. I've been having trouble sending queries to MySQL for data from the tables in the DB, instead of the required data i get an error message window appear and my python server crashes(which is running on my machine, by the way i'm using version 2.2.2 of zope on windows ME). Somethimes the error message is blank, other times it's PYTHON15.DLL or MYSQL.DLL when it crashes. Also when i submit a query to add data to a table zope returns what appears to be a error message in my browser, which the zope control panel is using, but the data is still added to my DB table. When submitting a query to extract data, if my python server doesn't crash, zope returns the following: Error, MySQL.error: have an error in your SQL syntax near ' '', '', '', 2000 )' at line 3 -------------------------------------------------------------------------------- SQL used: SELECT * FROM songdetails WHERE( '', '', '', '', 2000 ) I'd be most grateful if you could provide some answers to any of these probelms as soon as you can. Even if you don't know if you could point me in the direction of someone who does. Cheers Alan

by wade naveja 16 Jan '01

16 Jan '01

i'm using zclient as outlined in http://www.zope.org/Members/lstaffor/ZClientMethod to serve pages from another web server as if they were being served form my zope server. how would i write an exception to handle the case of the other web server being down? when the other web server is down, i'd like to include a bit of text saying "this service is temporarily unavailable. blah, blah, blah...". from ZPublisher import Client def web_client(url = 'http://www.server.com/', username = None, password = None, **kw): '''access http server''' if kw: return Client.call(url,username,password,kw)[1] else: return Client.call(url,username,password)[1]

Newbie: python to create a Zope page?
by David Humphreys 16 Jan '01

16 Jan '01

So, I'm about 72 hours into Zope, and totally loving it. I'm stuck on something simple, and I was hoping I could get a little help. Short question: How do I get python to create a Zope page? I'm looking for some simple source code that would walk me through that. I've looked through the online documentation and, if it's there, it's pretty well hidden inside of other things... Longer questions: I'm trying to get python to suck in a bunch of XML pages and create Zope pages out of them. I understand that there's a Zope / XML group, but it's not clear to me if there's any useable code that's come out of that initiative so far. (So, question 1: is that true?) I'm trying to create a lightweight content manipulation system for the company's site, and I'm thinking that what I want to do is: a) take the existing site's content, b) format it into XML with python (thus discarding its current format, and maintaining important metadata), c) get python to create Zope pages, d) create an editing system using Zope, and e) publish those pages out to static pages (and potentially other formats) on a regular basis. As a general strategy, is this a good way to go? Are there pointers out there that could help me with this quest? Thanks in advance! ---------------------------------------------- David Humphreys dhumphreys(a)macromedia.com * 415/832-5917 or dhumphreys(a)onemain.com (pager)

Zope from a php perspective
by Vincent Stoessel 16 Jan '01

16 Jan '01

Hello All, I have starting testing Zope as a potential CMS for some production websites. I think I understand the basic of to create and edit pages in the Zope system. I haver a few questions for those more experieced with this system. I am very familiar with php so I need someone to translate these concepts for me. include_path : I understand that you can automatically include objects into pages by referencing their id, I also understand that Zope automatically searches up the parent chain till it finds a matching object. But what if I want to include something outside of the tree? or just wanted a central repositories of object that I wanted to be able access from anywhere. i.e cars colors | | ford red | toyota if cars and colors are on seperate branches, how an I "cross" the brnches to access objects. Publishing tools: I'm going to be doing some news related sites, are there tools specially made for this type of project? I'm using 2.2.5 , does Ztemplates and Zpublisher automatically come with this version? They are not listed in the "products" folder in the management screen. Where can I find the the full docs on Ztemplates and Zpublisher? comment: I find the Zope website hard to extract info from. I suggest a seperate section for ducumentation of the core functionality and another section for additional add-on modules (products?)
