Subclassing File
by Edward Muller 29 Oct '99

29 Oct '99

I want to be able to subclass file, then add a few extra properties. when I do this and define a new property sheet, then add a view for the property sheet it doesn't appear. What's Up? Is File special in some way? ---------------------------------------------------------------- Edward Muller / Firm Wide Architecture - Systems Architect Paine Webber - 1000 Harbor Blvd. 5th Floor - Weehawken, NJ 07087 201-352-0190 - 201-272-7002 (fax) - mailto:emuller@painewebber.com ----------------------------------------------------------------

CSS & Zope howto
by Ethan Fremen 29 Oct '99

29 Oct '99

Zopistas, I have uploaded a howto about using CSS in the Zope environment. It is fairly thorough, an covers a lot of CSS ground. It covers how you can use CSS, Aquisition, and DTML to make your site very dynamic. It's from a standards-based perspective. http://www.zope.org/Members/mindlace/css_zope is the URL. -- Ethan "mindlace" Fremen you cannot abdicate responsibility for your ideology.

ANN: Brasil On-line launches Zope-based news service
by Luciano Ramalho 29 Oct '99

29 Oct '99

Brasil On-line (BOL) launched yesterday a real-time news service based of the Zope application server platform. The service, which can be seen an <http://www.bol.com.br/noticias/>, is fully automated. Feeds from Reuters and Climatempo, a local weather information provider, are retrieved every 15 minutes and pages are updated accordingly. A third information provider, Gazeta Esportiva, uses remotely accessible forms to post their stories. All pages in the BOL news areas are generated by a Zope application developed by Hiperlogica of Sao Paulo, Brazil <http://www.hiper.com.br>. The code that retrieves weather information was written directly in Python, and feeds a PostgreSQL database, which is queried by Zope. The Reuters material is pulled directly by DTML Methods, which use the ZClient facility included in Zope. The stories are then copied to Zope DTML Documents to be served locally. The BOL news area is the eighth Zope based site developed by Hiperlogica. Other recent cases include the American Chamber of Commerce in Sao Paulo, Brazil <http://www.amcham.com.br>, MAGNET magazine <http://www.magnet.com.br> and the Achademia education portal <http://achademia.uol.com.br>. Early on Hiperlogica focused on Zope. Their first client -- IDGnow!, <http://www.idgnow.com.br>, Brazil's leading technology news web site -- uses a Zope-based solution since April 1999. "Zope is an extremely flexible platform where programmers, designers and end-users of all skill levels can collaborate in way that is more rational and cost-effective than any other system I have tried in five years of web development experience.", says Luciano Ramalho, one of the founders of Hiperlogica. -- The Hiperlogica team wishes to extend to the creators of Python and Zope, and to the entire Zope community, our heartfelt thanks and congratulations on such wonderful pieces of software engineering.

Re: [Zope] Medusa performance - was: HELP: downloading file from netscape/old IE can frozezope
by Gilles lavaux 29 Oct '99

29 Oct '99

Hello, I have used medusa to build a 'host monitoring' system (very easy:I just had to code a module). And I find medusa extremly fast : I have tested it at ~3 millions hit/day(~33hit/sec) whithout problem, actualy I don't know what is the top limit on my config(dec alpha 433). BUT this was only with very small pages. What I dont understand with zope2 is why I have 7 process started: 'python z2.py -D' ?? If I understoud correctly medusa, it's running in a single process, so does it means that Zope use 1 medusa http sever + N (6??) 'zope process' to handle up to N (6?) requests simultanously? How does the Zope2/medusa part works?

Uncatalog problem... Cannot delete Zclass instance!!
by Geir B Hansen 29 Oct '99

29 Oct '99

I have a Zclass newsdoc, with base classes of catalogaware and object-manager.. Everything worked nicely, it added and deleted itself nicely from the catalog and in all aspects behaved as expected.. The problem was when i tried to delete an instance of it.. I get the error : Error Type: ValueError Error Value: Uncatalog of absent id 'exp/news/HRnews/newsdoc199910101612' - So it evidently cannot uncatalog the newsdoc from the catalog, but should this stop it from deleting the instance ?? I tried manually removing it from the catalog, then deleting it -result : didn't work.. Tried clearing the entire catalog, then deleting - result : didn't work.. Tried indexing all documnets again, then deleting - result : didn't work tried changing the id of the Zclass, to break the documents, so that they would not inherit from zcatalog - result : they didn't break, thus it didn't work .. I'd really like not having to actually delete my Zclass and the recreate it.. Ideas on what i might do wrong ?? Traceback follows: Error Type: ValueError Error Value: Uncatalog of absent id 'exp/news/HRnews/newsdoc199910101612' Traceback (innermost last): File /usr/local/funcom/intranett/python/Zope2/lib/python/ZPublisher/Publish.p y, line 214, in publish_module File /usr/local/funcom/intranett/python/Zope2/lib/python/ZPublisher/Publish.p y, line 179, in publish File /usr/local/funcom/intranett/python/Zope2/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/funcom/intranett/python/Zope2/lib/python/ZPublisher/Publish.p y, line 165, in publish File /usr/local/funcom/intranett/python/Zope2/lib/python/ZPublisher/mapply.py , line 160, in mapply (Object: manage_delObjects) File /usr/local/funcom/intranett/python/Zope2/lib/python/ZPublisher/Publish.p y, line 102, in call_object (Object: manage_delObjects) File /usr/local/funcom/intranett/python/Zope2/lib/python/OFS/ObjectManager.py , line 392, in manage_delObjects (Object: ElementWithAttributes) File /usr/local/funcom/intranett/python/Zope2/lib/python/OFS/ObjectManager.py , line 264, in _delObject (Object: ElementWithAttributes) File /usr/local/funcom/intranett/python/Zope2/lib/python/Products/ZCatalog/Ca talogAwareness.py, line 134, in manage_beforeDelete (Object: CatalogAware) File /usr/local/funcom/intranett/python/Zope2/lib/python/Products/ZCatalog/Ca talogAwareness.py, line 191, in unindex_object (Object: CatalogAware) File /usr/local/funcom/intranett/python/Zope2/lib/python/Products/ZCatalog/ZC atalog.py, line 357, in uncatalog_object (Object: ElementWithAttributes) File /usr/local/funcom/intranett/python/Zope2/lib/python/Products/ZCatalog/Ca talog.py, line 373, in uncatalogObject ValueError: (see above) ------------------------------------------------ Geir B Hansen geirh(a)funcom.com Web-designer / Graphic artist Funcom Oslo ------------------------------------------------

Question is, > what killed it after it had been running awhile OK? Found the problem. It wasnt killed. It was never started... sigh. That machine was just setup for some testing later on, so the current load on it was very small. So it could run without the ZServer for a while, then crash and restart, run for a while, crash... etc. Well, I have learned some more about Zope, so atleast there was something good with it ;) Thanks. /Magnus Heino

That means that ZClasses which you create have to have the ZCatalog Aware Base class as the FIRST! base class. If any other class is before ZCatalog Aware, like Ojbect Manager, the Catalog won't know that it exists. Also make sure that the meta_types box in the search form has "All Types" selected with no other resrtictions. Good luck, Jason Spisak webmaster(a)hiretechs.com
