zclass instance problem
by Mike Mikkelsen 19 Oct '99

19 Oct '99

Hello, I just created a zclass but I can make an instance of it. The error reported is: Error Type: TypeError Error Value: argument title was ommitted When I choose the zclass from the "Available Objects", the only thing that is asked for is the object id, not a title. So I'm not sure where this error is coming from. Any help would be appreciated. Thanks. -- ========================================================================== Mike Mikkelsen mikk(a)microbsys.com Micro Business Systems http://www.microbsys.com Fresno Linux Users Group http://linux.fresno.ca.us Linux: The OS people choose without $200,000,000 of persuasion

We've used OD and Rational Rose. I can't comment on RR since I haven't used it, other than Jim has told me that OD is better at visualizing UML than RR (which is surprising, since the three authors of UML work for Rational). OD is also much cheaper than RR, and Rational has all kinds of 'support' and 'process' products that get you for more money if you go for it. OD could be a great application, but it has serious problems. Nothing too serious that couldn't be fixed with a decent alpha/beta cycle (or an open sourcing! ;) My beef with OD is that it's just *not* final software like they say it is. It could barely be called beta software. Today alone, it has caused me more grief than Microsoft Outlook! If they would fix these bugs and make some other improvements, I would recommend their software. They are responsive with their technical support and are allways helpful with our problems. We met them at LinuxExpo this year (where they had a demo running on NT :/) and they are a pretty small company and very friendly. -Michel PS.

I've seen a few messages talking about this kind of thing recently. When I had added the "default_catalog" property to the KMArticleStore, I had thought that this would be picked up via acquisition. Unfortuately, this property has to be set for each KMArticle instance (from what I understand). A change to the AddArticle method would probably do it... hopefully, I'll get around to this in less than 2 months :) Kevin

By calling addIndex, delIndex, addColumn and delColumn. The add/del Index methods add and delete indexes (surprise), and the add/del Column methods add and delete columns in the meta-data table. If my ZCatalog UML model wasn't currently in a hosed state due to our high quality modeling product, you could reference it (do I sound bitter?). -Michel

ZClass Product Difficulties
by Edd Dumbill 19 Oct '99

19 Oct '99

I'm having some difficulty with using my ZClass as a Product My Product works fine as I have built it, inside Zope - I can create new 'MyProducts' fine from the "Available Object" dropdown. I then create a distribution with the Control Panel distribution tab. Then I remove my development version of the product, stop Zope, untar the distribution product .tgz in the right place, and restart Zope. MyProduct appears in the Products list OK, but it doesn't appear in the "Available Objects" drop-down, so I can't create one anywhere. I'm going mad trying to solve this so any help would be appreciated! Thanks -- Edd

An import script can be used to suck pages off a filesystem or you can use Zope's FTP support to push them all up to Zope in one gulp using any old FTP client you want. -Michel

This is one of the biggest points to make about the control customers get from open source.

Costly.

Two DTML/Python questions
by Hunter Kelly 19 Oct '99

19 Oct '99

Is there a way to access builtin python functions (ie those in __builtins__) from DTML without resorting to external methods? Secondly, is there a clean way in DTML to check if an item in a ZCLass (descended from Object Manager) is actually an instance of another ZClass? Thanks, Hunter

Kevin, NO shame in fixing problems... > After much shameful delay, I have finally released KM|Net News 1.0... Unfortunately, I think that I've found another one. I tried to call the Catalog that the KMnetNews uses KMCatalog rather than Catalog, and tried to use it (having also put KMCatalog in the default_catalog entry in the Article Stores properties. I found that the system wasn't putting the new articles into the Catalog for me. After a while, I change the name of the catalog back to Catalog, and change the properties, and it burst into life. It looks like the name of the catalog is hard-coded somewhere.
