Re: [Zope-dev] pluggable brains - namespace blues
by Philipp Auersperg 03 Nov '00

the best answers are those answered by yourself: For all who want to know it: you have to explicitely give self as an extra parameter: concerning the example below: just call: rs[0].getName(rs[0]) and it works for me. Weird, but now I can enjoy my beer.... phil *********** REPLY SEPARATOR *********** On 03.11.2000 at 12:30 Philipp Auersperg wrote: I have a problem with pluggable brains: 1.

It seems that the namespace is somehow shreddered, I have to dig into that but if anybody can help it would spare much time! So finally my desperate question: How can I solve/workaround that problem to call methods in pluggable brains that access database-based members from a python method? thanks in advance phil

ZServer log buffer?
by J�lio Dinis Silva 03 Nov '00

03 Nov '00

Hi all. Supose you are saving z2.log on a mounted disk, either nfs linux or a WinNT cluster network name. If for some seconds that mounted disk became unavailable, isnt supose ZServer log system to buffer a little until the mounted resource became available again? I'm dealing with the problem that z2.log "write system" on NT are giving me a IOError when the resource becames unavailable for some seconds. If there isnt anything already to fix this, wouldnt be good if ZServer buffer a "little" until the resource became available and in the case the resource just completelly cease to be then ZServer just stop to write logs, instead of killing the process raising the exception? I know what you are thinking: just dont permit the resource to became unavailable dude! But supose you have active-passive resources in case of fail down and you need some seconds to automatically or by hand(not the case) fix the resource, wouldnt be nice for ZSERVER to, for instance, stop logging. Maybe this should not be addressed to Zope Log writes. Maybe this is more a system administration issue but... Thanx anyway for some comments.

CMS/publishing system
by Pete Prodoehl 03 Nov '00

03 Nov '00

[Note: this was also sent to cms-list(a)camworld.com/Content Management System Mailing List] I'm looking for opinions on Zope being used as a CMS/publishing system. Here's some rough notes on our situation and my thoughts on Zope. We run NT now, but would like the option of migrating to *nix. (Zope runs on both.) We want to deploy across 50+ sites. (Since it's open source, we'd spend our money on customization/development rather than licensing fees.) We'd prefer a browser based administration system. (Zope's already got a very good one.) Some questions I have are: How well does Zope integrate applications/cgi's written in ASP, Cold Fusion, Perl, etc...? As we've got a number of things we'd prefer to keep as is, and run alongside Zope. How does Zope deal with serving virtual domains off of a single NT box? What approach would that require? Zope looks like a really nice platform, any real-world evaluations would be most appreciated... (Besides what I've read on www.zope.org) thanks... Pete

Help wanted on Zope ZClasses/DTML please.
by Bowyer, Alex 03 Nov '00

03 Nov '00

Hi, I have only just started developing in Zope over this last week. I like it a lot, but I am having problems finding solutions to some of my more specific problems in the various zope documentations. I am hoping that if I describe my problems, one of you more-experienced Zope users out there will be able to help me. First some background: Basically I have written a news page which allows you to add/edit/delete articles from it. It is similar in some ways to the Zope HowTo "Build a searchable job board". It revolves around two classes: (UA stands for Update Australia, the name of the news page) UAArticle : A single article, to be included on the page. --------- Properties: article_title,article_author and article_text (self-explanatory) DTML Methods: index_html - renders the data from the three properties into HTML ready for inclusion in the news page edit - a page with a form to allow you to modify the content, submits to "update" update - processes the form results from "edit", updates the properties and redirects UAPage : the page itself, inherits from ObjectManager and has Add UAArticle permission defined. Each instance contains 0 or more UAArticles. ------ Properties: issue_date, issue_number, intro_text (self-explanatory) Methods: index_html - renders the page to HTML, both from these properties and by calling the index_html of each subcomponent UAArticle. edit - a set of forms for modifications to edit the above three properties and add a new article, or select an article to edit or delete. update - processes updates to the UAPage properties that have been made on the edit page. edit_article - once an article is selected and the Edit button is clicked, this finds the article, calls the edit method and gives feedback. add_article - a form to create a new article and add it to the UAPage. create_article - processes the data from the add_article form and actually makes the object and adds it. delete_article - once an article is selected and the Delete button is clicked, this finds the article, deletes it and gives feedback. Now to the problems I have got: 1) I cannot get my delete_article method to work. I figured I need to use manage_delObjects, but I can't find a working example to copy from and my code doesn't seem to do anything. The following code gets called by a form with a field called article_to_delete which is the title of the article we want to delete: <dtml-var standard_html_header>  <dtml-call "REQUEST.set('id_to_delete','NULL')">  <dtml-let the_match="REQUEST['article_to_delete']">  <dtml-in objectValues> <dtml-with sequence-item><dtml-with propertysheets><dtml-with UAArticleClassPropertySheet> <dtml-if expr="article_title==the_match"> <dtml-call "REQUEST.set('id_to_delete',title_or_id)">  </dtml-if> </dtml-with></dtml-with></dtml-with> </dtml-in>  <dtml-if expr="REQUEST['id_to_delete']=='NULL'">  <h2>Article not found</h2> <P>Could not find the article to delete.</P><P><A HREF=edit>Return to maintenance page</A></P> <dtml-else>  <dtml-let the_id="REQUEST['id_to_delete']">  <dtml-call "manage_delObjects('the_id')"> <h2>Article deleted</h2> <P>Deleted article '&dtml-the_match;' (id='&dtml-the_id;').</P><P><A HREF=edit>Return to maintenance page</A></P> </dtml-let> </dtml-if> </dtml-let> <dtml-var standard_html_footer> This gets an error that the_id does not exist. But I can't put <dtml-call "manage_delObjects('REQUEST['id_to_delete']')"> because that is quotes within quotes within quotes. I also tried <dtml-with the_id><dtml-call "manage_delObjects()"></dtml-with> but that doesn't seem to do anything. What is the correct way to use manage_delObjects? 2) I need to be able to make a "Back" button on the UAArticle's edit page that will return to the UAPage's edit page. The problem is that if I use <A HREF=edit> it just goes to the edit page of the object, because our current location is within the UAArticle not the UAPage. Is there a way to get the name of an object's parent (or its own name for that matter) and use it to construct a URL? 3) When redirecting or linking to a page I have already visited, how can I force a refresh? I tried the JavaScript window.location.reload(true) but I think that is only supported by Netscape. It didn't work in IE5 for me anyway. 4) What is the best way to handle security with ZClasses. In my example I want the index_html pages to be public but everything else to require a password. I managed to require a password for a particular instance of the UAPage, but that affects both the index_html and the edit pages. Thanks very much for taking the time to read this - I hope someone can put me out of my misery! - I have been fiddling around with the code for ages, getting nowhere fast, and the documentation wasn't much help in these areas. It just seems to cover the basics of ZClasses.

RE: [Zope] PHP and Zope

If you want to you could just use Apache as a front end server serving php pages, and as a proxy to Zope. That way you can have the best of both worlds. But I would recommend using Zope, as you will have far greater possibilities for re-use of your code. Regards Max M -----Original Message----- From: Vincent - D. Ertner [mailto:vincent@eec.de] Sent: Friday, November 03, 2000 2:44 AM To: Zope Subject: [Zope] PHP and Zope Hi Zopers, I learned PHP and now discovered Zope. So I'd like to put a simple question: What's the best way to incorporate the advantages of PHP and Zope? Should I focus on one and forget the other? Okay, these are two questions and I honestly doubt that anyone would suggest to drop Zope ;-))) Anyway: Please gimme some starting hints on my way to the perfect content managed web site!

Zope/Posgresql/RedHat Linux
by Chris Marshall 03 Nov '00

03 Nov '00

I hope that this is the correct forum for a question of this nature. I would like to know if anyone is using the combination of Zope/Posgresql/RedHat Linux in a commercial application to determine if it is a suitable combination. I have attempted to configure this combination but run into trouble compiling PoPy-1.4.1 on RedHat Postgresql - and have not been able to resolve the problems via RedHat or Mixadlive - hence my question.
