Z class complexities
by Nolan Darilek 01 Oct '00

01 Oct '00

I'm having a kinda complex problem, and hopefully my explanation can do it justice. :) I'm using zope to construct an XML document from the contents of a folder. Basically, the folder's index.xml iterates through the folder's contents, rendering each object to produce the final document. The objects are separate z classes which combine various properties into a small snippet of the larger XML document. The z class has a render() method which combines the properties into the XML snippet. I have a Render view configured to run this method, and it works. (Though for some reason it adds a <html><head>..., which I'd really like to get rid of. How can I?) I've written the index_html to collect the individual objects and concatenate their contents into an XML document. The code for the method is below: <?xml version="1.0"?> <espsetup-list> <dtml-in "PARENTS[0].objectValues('ESPPackage')" sort=title> <dtml-var "_[_['id']].render()"> </dtml-in> </espsetup-list> This almost gives me what I want (I say "almost" because everything works, short of the render() call.)

And, as previously stated, the render() method runs without errors when invoked via the view. Yet, trying to display this document from within another doesn't work. Can anyone please advise? Thanks a bunch in advance.

working crontab restart script on FreeBsd
by George Osvald 01 Oct '00

01 Oct '00

I was trying to do this for a little while so in case anyone's interested, here it is. Most of the code was kindly sent to me by other people so do not blame me for the mistakes. This script(auto) checks ZOPE every 15'th minute and if it does not run, it will restart it. It has been working without a problem on FreeBSD 4.0 after I patched ZOPE's pidfile for LF's. (without that little operation it returns an error message and restarts ZOPE every time without checking it) I am running this from crontab: SHELL=/bin/sh 0,15,30,45 * * * * /home/user/auto And this script(auto) is sitting in my user directory: #!/bin/sh ZOPEDIR="/home/user/zope" INFOMAIL="mail(a)okstudio.com.au" STARTFILE="$ZOPEDIR/start" STOPFILE="$ZOPEDIR/stop" PIDFILE="$ZOPEDIR/var/Z2.pid" PID1ACTIVE=0 PID2ACTIVE=0 if [ -x $STARTFILE ]; then if [ -r $PIDFILE ]; then PID1=`cut -d" " -f1 $PIDFILE` PID2=`cut -d" " -f2 $PIDFILE` if kill -0 $PID1 2>/dev/null then PID1ACTIVE=1 fi if kill -0 $PID2 2>/dev/null then PID2ACTIVE=1 fi fi if [ $PID1ACTIVE -eq 0 -o $PID2ACTIVE -eq 0 ]; then $STOPFILE >/dev/null 2>&1 sleep 10 $STARTFILE date | mail -s"Zope restarted" $INFOMAIL >/dev/null 2>&1 fi fi Regards, George

handling date properties in <dtml-if>
by Timothy Wilson 01 Oct '00

01 Oct '00

Hi everyone, I've created a simple ZClass to allow our Human Resources dept. to post job openings on our Web site. There's a DTML method that iterates through a folder containing all of the 'Job Board Entry' instances and displays them in an HTML table. No problem there. The ZClass has a number of properties including two dates, 'date_posted' for the date that the job is officially available and 'offer_expires' for the date the job opening officially closes. I want to display only those jobs for which the current date is on or after the 'date_posted' and on or before 'offer_expires'. I've tried a bunch of things, but haven't hit upon the winning answer. Any takers? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

One page for different selections
by Rafael Sep�lveda 01 Oct '00

01 Oct '00

Is there a way to make a variable change its value depending which 'href' the user clicks in order to change the contents of the next page viewed? For example, I want to have a page with six links, and depending which of them the user clicks, a variable will change its value so the next page will display that data refered on the link clicked. Is there a way to do this without having six files, one for each other; just having one file with that variable? -- Rafael Sepúlveda <rsepulveda(a)linuxmty.org> http://www.linuxmty.org/people/rsepulveda 1024D/1981FDE7 F13B C41C 739B 7233 F738 D68E 2947 D868 1981 FDE7

I a trying to make the DTMLTemplate Product work on Zope 2.2.1 No luck so far ;( I can add a DTMLTemplate instance but when I try to edit it, I get: Zope Error Zope has encountered an error while publishing this resource.

XMLRPC:XML Compressors - anybody experienced it?
by Philipp Auersperg 01 Oct '00

01 Oct '00

Since XML blows lots of overhead over the line sending large amounts of data via XML becomes a performance question. There exist XML-compressors, for example XMill that address this problem. What I need is integrating such an XML compressor into the Zope XMLRPC mechanism, Before I do something that is already done by somebody else: Did anybody play with XML compressors for Zope or at least have a hint how to do that? thanks

newbie:zclasses within zclasses (down the hill)
by Sven Hohage 30 Sep '00

30 Sep '00

I've searched on a solution for this problem for hours. I want to build a site-structure where users can add with help of templates new webpages. One webpage for itself is a ZClass(baseclasses:ZObject, _ZClass_for_Folder, _ZClass_for_CatalogAware, ZObjectManager). ---The formular: ---<form action="second"> <dtml-tree branches_expr="objectValues(['Spam'])"> <input type="checkbox" name="destination" value="<dtml- var id>"> <dtml- var "absolute_url()"> </dtml-tree> The user can decide where to build the webpage(ZClass with metatype 'Spam') In 'second' he can choose a template and then the constructor_site builds it: --<dtml- with "_.getitem(destination,0)"> --<dtml- with "manage_addProduct['Spam']"> <dtml-call "Spam_page_add(_.None, _, NoRedir=1)"> ---</dtml-with> I've also tried -><dtml-with "_[destination]"> and also with not saving the 'id' but the 'absolute_url' in 'destination'. The constructor_site is on the top level of the website and he doesn't know the folders downside.How to solve the problem???Please help me because it's only two days to finish everything. _______________________________________________________________________ 1.000.000 DM gewinnen - kostenlos tippen - http://millionenklick.web.de IhrName(a)web.de, 8MB Speicher, Verschluesselung - http://freemail.web.de
