The ZQR (Zope Quick Reference; search on zope.org or zdp.zope.org) or press the help button in your Zope 2.2.2 management screens. Dieter

Re: Version Lock/save/discard Problem

>We have had the same problem with "saving" Versions on zope 2.2.2 + >ZEO. Our ZSS servers are on linux and our Zope Clients are on NT >(don't ask). I have all ZSS and ZCS on NT but I isolated the possible zeo's related problem running my Data.fs on a standalone zope and the problems persisted. >The only solution that worked for us so far is to repeatedly modify >the locked object and re-save the version. If it doesn't work at >first try again after a few hours. Eventually (after a dozen or so >tries) it seems to sort itself out. >We haven't seen documents become folders yet, but most of the work >was done in ZClasses. I solved the problem with some packs to the Database. In no understandable way after one of the packs the discard and save worked okay. In one of the packs I got this output: ERROR(200) ZODB FS FS21 ERROR: Bad reference to ('\000\000\000\000\000\010kQ','myversion') ERROR(200) ZODB FS FS21 ERROR: Bad reference to ('\000\000\000\000\000\010]\250','myversion') Its obviously there was something wrong with myversion object, but only after some more packs the save/discard worked okay. But I quit versions because the locking of a folder when you add objects is not a good feature of versions, specially if the one locked is root, means you just loose the possibility of changing your online "version" of your site like adding new objects, and changing locked ones. I know this versionlock happened with CatalogAware objects from experience with zope 2.1.6 but for instance the locking of a document even for a change out of the version is something never happened in 2.1.6. I'm just seeing this in 222, maybe this is a result of those objects being in a locked folder.

RE: [Zope] Date

Here you go Tom. I think this is what you are looking for. There's probably a more streamlined way to implement it, but this seems to work nicely. Sorry for the VB-style variable names (grin) Hope you find it useful. -Eric. Here's the (ONLY) DTML used to test the functions: -----8<-----8<-----8<----- <dtml-call expr="REQUEST.set('d', ZopeTime('1999/11/21'))"> Here's the result of dateInNMonths on November 21, 1999 + 6 months:<br> <dtml-var expr="dateInNMonths(this(),d, 6)"> <br> -----8<-----8<-----8<----- I implemented it using two "Python Methods" as follows: -----8<-----8<-----8<----- ID: daysPerMonth Parameters: ZopeDateTime <-- Pass in a Zope Date Time object Function: if ZopeDateTime.isLeapYear(): intDaysInFebruary = 29 else: intDaysInFebruary = 28 strMonthName=ZopeDateTime.Month() dicDaysPerMonth = {'January':31,'February':intDaysInFebruary,'March':31,'April':30,'May':31,'J une':30,'July':31,'August':31,'September':30,'October':31,'November':30,'Dec ember':31} return dicDaysPerMonth.get(strMonthName, 0) -----8<-----8<-----8<----- ID: dateInNMonths Parameters: self, ZopeDateTime, Months Function: days = self.daysPerMonth(ZopeDateTime) - ZopeDateTime.day() + 1 i = 2 while i < Months: nextDate = ZopeDateTime + days days = days + self.daysPerMonth(nextDate) i = i + 1 days = days + ZopeDateTime.day() - 1 return ZopeDateTime + days -----8<-----8<-----8<----- -----Original Message----- From: Eric Walstad [mailto:Eric@Walstads.net] Sent: Tuesday, November 21, 2000 10:19 AM To: Tom Deprez Subject: RE: [Zope] Date Hi Again Tom, OK, This is an interesting one that I may need later on.

zope 2.24b1 upgrade on win98 crashing. errno 9?
by jimbo 21 Nov '00

21 Nov '00

I'm not sure what I've done to my system. The upgrade went fine at first so I think it might be something I've done since this morning. I just deleted some product folders I had been working on. Searching thru records seems mysql adapter might be the problem. I deleted the mysql folders and still can't start my Zope. At this point I should start work on mastering Zope debugging. What would be the easiest and quickest way to get my zope restarted without much damage? Here is the error message. IOError: [Errno 9] Bad file descriptor

random object with properties
by Kevin Worth 21 Nov '00

21 Nov '00

I'm trying to find/write a method that will choose a random image from a folder (easy, using the random how-to) But I also want to display the caption for the image, which is a property of that image. This method: <dtml-var expr="_.whrandom.choice(objectValues('Photo'))"> <dtml-if caption><dtml-var caption></dtml-if> presents me with a random photo, but no caption. At one point, I had it pulling out a random photo and a random caption, but I need the associated caption. What am I missing here?

SAP Database Adapter available

Hi folks, since the SAP Database has been release on Linux as GPLed Engine (http://www.sapdb.org) is there a compatible adapter for Zope ? --- The only "intuitive" interface is the nipple. After that, it's all learned.
