Link: http://www.zope.org/Members/k_vertigo/ZopeProducts/NewsCenter/index_html Changes: ZCatalog Searches PyXML distro download link updated Minor fixes. Caveats: IF YOU"RE USING ZOPE 2.2.1 - ZCatalog now generates log messages for attempts to uncatalog items not in the catalog. The update methods tries to uncatalog before updating and cataloging, otherwise older news items might still exist in the catalog. hence you will see lots of catalog errors fly by the when a channel is initially published. this is harmless but annoying. Testing: I tested it on a fresh compile of 2.2.1 and retrieved an ocs channel list, rss channels, published/unpublished them, and searched the channels. Kapil

ANN: ZWikiZC version 0.7.3 alpha
by Johan Carlsson 29 Aug '00

29 Aug '00

The ZWikiZC version 0.7.3 alpha completely rely on ZCatalog for looking up WikiPages from WikiNames. No references are stored in the ZWikiZG page letting cut&paste, delete and other management actions ignore updating links. I bellew this is a more scalable solution than in the version 0.7.2 alpha. Bottle neck might be if a page contains alote of WikiNames. I also cleaned it up a bit (remove some hacky stuff from the old ZWiki). Also added are keywords, wiki_meta_types and author_ids. http://www.zope.org/Members/johanc/ZWikiZG/wiki Cheers, Johan Carlsson

Re: "Automatic" creation of searchable documents from Oracle DB tables
by Satheesh Babu 28 Aug '00

28 Aug '00

Hi Chris, I've a system, where folks enter data through some HTML forms -> DTML methods -> Oracle tables. This is mainly used for storing web page content. Then I generate a static document using a chosen template, from the database. I think this is some what similar to your requirement. This is seemingly a round about way of doing things. My reasons: 1. I'm not really confident in ZODB recovery in case of a data corruption. 2. I'm lot more confident of getting data out of Oracle using SQL, than writing Python on ZODB :-( 3. Our content can grow quite large, 20-25GB is very realistic. 4. Oracle's interMedia search is very capable. 5. As long as core content is in Oracle, the front end can be Zope or PHP or ASP as the suites might dictate. Why the hell do I make static document back from database? 1. Dynamically creating documents from Oracle is time consuming. So, I create static version as some kind of cache. 2. To create links between data in database, it is a lot more easier for users, with static versions. I've working code for this that I could share with you. Ideally what I want is 1. ZClass to reflect document attributes 2. When one manages a ZClass instance, corresponding record in Oracle gets managed as well. Didn't get time to check this properly. Someone told be ZPatterns will be of great help. But then again, Paul Everitt has said that they are working on Oracle+ZODB. I worked on an Oracle based storage for some time, but then dropped it. To make a long story short, for help on making static content from RDBMS, there is an excellent HOW-TO at www.zope.org/Members/rossl/GenerateStaticPages HTH vsbabu(a)csoft.net http://www.mamlegault.com/~vsbabu/

by Philipp Dunkel 28 Aug '00

28 Aug '00

Hi Zopers, I'm really happy that the with the newest zope releases the zCatalog has got more stable. I'd like to use it for my Products, but I don't have the time now to port everything to the new zope version. Is it possible to only use the new catalog and which files do I have to change/update ? Or is the catalog even as a product available? TIA philipp dunkel

Advice for new zope installation
by Henk Schets 28 Aug '00

28 Aug '00

Hi, After reading all the info about zope, I am very impressed with the possibilities it can deliver. However, before I migrate our existing site, I need to be certain about certain topics : - how easy and reliably can I manage my virtual hosts (about 8 sites right now) ? Very important. - how stable is Zope regarding to Apache on Linux ? - we have a MySql database, is it easy to connect with Zope ? - can I access the Zope internal database with e.g. ODBC ? - can I use log analyzers to get some statistics about our site ? - any advice about migrating an existing site ? Thanks, Henk Poppunt webmaster http://www.poppunt.be

Re: [Zope] Showing the name of a file-type form variable
by icottee＠bluefountain.com 28 Aug '00

28 Aug '00

Hi file.filename should be what you are after. e.g. In my latest project I set a variable myFileName to be the name of the file uploaded using <dtml-var "REQUEST.set('myFileName',file.filename)"> where file is the name of my file upload control in my form. Ian Original Message --- Hi Zopers I've got this:: <td><input type="file" name="file" <dtml-if file> value="<dtml-var "file">" </dtml-if> ></td> Which returns:: <ZPublisher.HTTPRequest.FileUpload instance at 131dc48> in the input box. I'd really rather have the filename. How does one do that?

unauthorized when accessing /manage in zope 2.2.1
by Philipp Dunkel 28 Aug '00

28 Aug '00

Hia Zopers, I'm totally confused and I couldn't figure it out in 2 working days so here it is: I have a Zope Product that makes use of different nested classes. When I create an instance of this product I always get an "unauthorized" error when clicking the instance in the management interface (=accessing <instance>/manage) even if I am logged in as a manager or superuser. The strange thing is that for example <instance>/manage_access works fine for me. I tried all stuph with permissions, switched acquisition on and off, added 'manage' to my permission tuple, gave everyone the right to view management-screens and so on. The error message says only "unauthorized" and the traceback points to Management.py Any Ideas? (btw: it worked fine in 2.1.6) thanx a lot philipp dunkel, zReal Productions, The Hague

Problem with SiteAccess 1.0.1
by William JOYE 28 Aug '00

28 Aug '00

Hello, I have some minor problems with SiteAccess 1.0.1 and Zope 2.1.6 + hotfix. 1. When click on the folder that contain SiteRoot, I need to enter again login and password. Why ? 2. When I delete an object, I have always an script error message. Why ? Are these problems already fixed ? Is the SiteAccess 1.0.1 product stable enough to use it in production ?

Sub Class Question
by Daniel Rusch 28 Aug '00

28 Aug '00

I've created a BasicMethod which is derived from the DTMLMethod. everything works great until I try to have the sub class's (BasicMethod) __call__ method call the super class's (DTMLMethod) __call__ method. class BasicMethod(DTMLMethod): """BasicMethod objects are DocumentTemplate.HTML objects that act as methods whose 'self' is the BasicMethod itself.""" meta_type='Basic Method' def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw): print 'Sub Class __call__' DTMLMethod.__call__(self, client, REQUEST, RESPONSE, kw) Globals.default__class_init__(BasicMethod) when I view the BasicMethod in Zope, I get: Error Type: TypeError Error Value: too many arguments; expected 4, got 5 I believe that I need the self arg, if I remove it I get an unbound python method error. Any thoughts??? DR
