newbie ?: zclass propertysheet datatypes
by Daniel Chudnov 02 May '00

02 May '00

Trying to add a date property to a class, Zope's giving me an "Invalid Date-Time String" when I leave the initial value blank. Is this a configuration problem (rh6.0, Zope 2.1.6 w/zserver) or by design? There shouldn't be a default value for this property in the interface I'm building... TIA, -Dan

>CatalogAware ensures that objects are added to the catalog *when they >are >created*. The easiest thing to do would be to use the Find >command in the >Catalog to add the objects. Ok, I know that... But in my case the best way is to have my objects indexed in the catalog automatically *when created* adding this base class. My problem remains with my older instances before the adition of the CatalogAware base class. They are somehow broken but I cant debug that. >BTW, those objects are aware that they have CatalogAware as a base > >class...you'll probably get an error if you try to delete one, >because >it is not in the catalog, and the CatalogAware code will try >to remove it >from the >catalog. No :( thats not the case. I can delete with no prob. I've made restarts and still the older instances arent aware that they have CatalogAware as base class. Something is wrong, but I dont no what because everything looks ok, no broken products, etc. The new instances I create are aware of the new base class, but the older ones are just something apart from my and zope's logic. Anyway, thanks Kevin. ps. I love kmnetnews ;-) ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Transparent Folders

02 May '00

I just tried this out and it is hot! I tried arbitrary nesting of multiple transparent folders. I'll keep testing it. Nice product. I think it should be in 2.0. All my best, -- Jason Spisak 444(a)hiretechs.com

Time Lapse Natural Wonder
by Jerry 02 May '00

02 May '00

Hi Zope Fans, Maybe I'm just a hopeless geek, but I have to say this. Watching the development of Zope and the Zope Community taking form on these lists is about as awe inspiring as trying to imagine a caterpiller pulling itself apart by the chromosomes and reconstructing itself into a butterfly. You can watch it happen, with your own eyes, know it's real, and still never comprehend even faintest glimmer of how such a thing can take place. Zope was a caterpiller, a natural wonder in its own right, however modest it may have appeared to many, who only saw a crawling leaf muncher. ZEO, PTK, ZopeStudio, RIPP, and all the rest are setting Zope up to blow the minds of any Web Hacker who ever thought he know what HTML was for. Thanks so much to all of you amazing folks! Sincerely, Jerry S.

DateTime.py patch
by Shane Hathaway 02 May '00

02 May '00

Zope fans, I have just done a line-by-line audit of DateTime.py. There were a number of issues, some of which have been submitted to the collector. I have corrected everything I could find. Gregor Hoffleit recently submitted a patch for DateTime.py as well. He made some of the same corrections I did, though in a different way. The major changes are: - Usage of integer arithmetic where possible to eliminate rounding errors. - Better support for daylight savings time. - Usage of long integer milliseconds, making it possible to do date comparisons with more predictable results. - Date comparisons are now time zone independent, meaning that a DateTime set to 3:00 PM in GMT-5 is equivalent to a DateTime set to 4:00 PM in GMT-4. If do any work with Zope's DateTime or have had any issues with it, please install this patch so it can be fully tested. I have already tested it to the best of my ability. I expect this to become part of the main distribution once it has been tested. http://www.zope.org/Members/hathawsh/DateTime.py There is one change made by Gregor which I feel I could not incorporate. Gregor added the "CET" and "CEST" time zones to the list of recognized time zones. Rather than add it now, I would prefer to get a complete list of zones which are not included (EDT, which happens to be the time zone I am in right now, is also missing.) For now, those zones should be correctly translated to GMT offsets. On a slightly different note: Recently there was a thread that described a problem with the time format of Z2.log. That problem is unrelated to DateTime.py. ZServer/medusa/http_server is written incorrectly; where it accesses gmtime() it ought to be calling localtime(). Also, it needs to be updated for daylight savings time the same way DateTime was. Shane

Changing Zclass Base Classes
by julio dinis 02 May '00

02 May '00

Hello Zopistas! I have a product MyProduct with a zclass MyClass. I have many instances of MyClass. I decided to add Catalogue_aware base class to MyClass. Now when I create a instance of MyClass automatically add to my Catalog. Everythin ok. But. I thougt that now if I copy the instances I created before MyClass had Catalogue_aware has base class this instances would be added to my catalog. Wrong. Looks like the instances didnt inherited the adition of this new base class. Can I do any operation to this instances(objects) in order "for them to realize" they now have Catalogue_Aware as base class?
