ZCatalog only requires the objects being URL addressable; cachability is not an issue. Dieter

Cut support
by Andy McKay 30 Jun '00

30 Jun '00

Heres a wierd one: I have a class inherited off of DTMLDocument. The object's I create from can be happily copied, deleted, renamed and pasted in pretty much any order. But when I do a cut then paste I get an error message relating to ac_acquire I guess trying to get hold of the absolute_url (for cataloging purposes). I assumed a cut and paste would be a copy, delete, paste in that order. Put in would appear not to be, since I can do that by hand. Thanks in advance.

Question from ZopeNewbies poster. . .
by addyd＠unk.edu 30 Jun '00

30 Jun '00

I am forwarding to this list the following question asked on the ZopeNewbies discussion list today. I have told the poster about this list. You may wish to post your answer both here and on the ZopeNewbies discussion list page to make sure the poster sees your answer. Author: Kelvin, Tze Wai Cheong Posted: 6/30/00; 3:46:51 AM Msg#: 658 (top msg in thread) I'm developing a web-site which requires the storage of images in the database. I have defined this field as LONGBLOB in my database tables. The problem is I can't insert the image at the insert form, and worse of all I don't know how to start. according to the mySQL manual from mySQL.com's documentation, I should be storing the path of the picture file into the database. I have tried but ZOPE defined a floating-point error regarding the field. How should I go around this? ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Darren Addy Internet Specialist and Interim Web Presence Coordinator Office of Information Technology Services University of Nebraska at Kearney

Accesing a new context from a manipulated string
by Michael Bernstein 30 Jun '00

30 Jun '00

Here's my problem: given a method itemURL(), that typically returns a site relative URL such as '/about/', I need to change to the appropriate directories context using <dtml-with>. In short I need to do the equivalent of <dtml-with about>. The closest I've gotten so far is: <dtml-with expr="_.getitem(itemURL(), 0)"> which generates a KeyError: /about/ in the traceback. Can anyone help me truncate the extra '/'s off of this string and pass it to the <dtml-with>? Michael Bernstein.

RE: [Zope] Kid clicking and Zope thread deadlock

My preliminary test indicates that indeed the deadlock is coming from the Sybase database adapter. Zope alone seems to be doing fine (what a relief!), even under intense bombardment of http form requests. I'll have more about Sybase deadlocking later, as I try to isolate the problem. I think the problem is not only with transaction-non_transaction interaction. The problem happens even after I connect all the Zope threads to Sybase, and use transactions for all threads afterwards. regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Their maillist is at http://www.eevolute.com/mailman/listinfo/zip Sadly, looking at the archives, it seems that the ZIP mailing list is dead. I hope it will come back to life. The only thing posted on it this month is an announcement of zzLocale, "a framework for Zope interface internationalization". http://www.zope.ne.jp/users/yemartin/zzLocale There is also Translator, that "helps with the localization of web sites built with Zope" http://www.zope.com/Members/fog/Translator Although I have not used these programs yet, internationalization will be an issue for me soon. This issue seems to come up every 6 weeks or so on zope(a)zope.org. I hope to see a FAQ for this soon from someone with more experience using these packages (it's author can feel free to cut & paste this email :). I also hope to see an announcement of updates of these & newer internationalization programs in the "Zope News" and "Zope Weekly News". These would be good ways to help keep the ball rolling! cheers --== Sent via Deja.com http://www.deja.com/ ==-- Before you buy.

Zope 2.2.0b3: can't call db_connection.query()
by Cary O'Brien 30 Jun '00

30 Jun '00

With Zope 2.2.0b3, I can't seem to call the query() method of a database connection any more. For example, with a PostgreSQL connection called dbconn, calling <dtml-with dbconn> <dtml-var "query('select count(*) from pg_class')"> </dtml-with> Works fine with 2.1.6, but with 2.2.0b3, I get... Zope Error Zope has encountered an error while publishing this resource. Unauthorized ... File /usr2/local/zope/Zope-2.2.0b3-src/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: dbconn) File /usr2/local/zope/Zope-2.2.0b3-src/lib/python/DocumentTemplate/DT_Util.py, line 327, in eval (Object: query('select count(*) from pg_class')) (Info: query) File /usr2/local/zope/Zope-2.2.0b3-src/lib/python/OFS/DTMLMethod.py, line 189, in validate (Object: test1) File /usr2/local/zope/Zope-2.2.0b3-src/lib/python/AccessControl/SecurityManager.py, line 139, in validate File /usr2/local/zope/Zope-2.2.0b3-src/lib/python/AccessControl/ZopeSecurityPolicy.py, line 158, in validate Unauthorized: query Any ideas? There doesn't seem to be any permission to set. What I would like to do is add some functions to the PostgreSQL DA so I can view table names and column names. -- cary

ZCatalog Proximity Search (was: RE: [Zope] ZODB or not ZODB?)

Proximity searches are searches for terms that are near in the document. ZCatalog uses "..." as near operator. It implements a proximity search as an "and" search and assigns the document a relevance that is inverse proportional to the distance of the term occurrences. > Q2 - Where can I find the minor patch you mentioned? I just searched > Zope.org and didn't see it. URL:http://www.handshake.de/~dieter/pyprojects/zope/near.pat The patch fixes Zope 2.1.6 ZCatalog's "near" operator. It will work only for Zope 2.1.6. ZCatalog is a development hotspot. Lots have changed in the CVS and for Zope 2.2. Maybe, a patch is no longer needed for Zope 2.2. URL:http://www.handshake.de/~dieter/pyprojects/zope/localfs.pat is the small patch for LocalFS. It gives LocalFS the necessary infrastructure, that Zope's "find" machinery works for it. This machinery is also used by ZCatalog. Dieter
