Propblem with script from Zope book
by Jamie 11 Apr '03

11 Apr '03

I'm having problems running this example script from the Zope Book, Advanced Scripting Chapter, p. 183 """ Returns all sub-objects that have a given status property. """ results=[] for object in context.objectValues(): if object.getProperty('status') == status: results.append(object) return results It seems to be starting an endless loop or something, the browser can sit for a half an hour and still not change.

Resouce not found can't be caught
by Thomas Guettler 11 Apr '03

11 Apr '03

Hi! The resource not found exception can't be caught. I tried the following: def unitTest(self, REQUEST): "docstring" try: self._unitTest(REQUEST) except: import traceback traceback.print_exc() But I get the meaningless page: """ Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: QWERTZUIOP GET """ Why is the exception in _unitTest not caught by my exception handler? I would like to have a stacktrace. Yesterday I had a related strange behaviour: raise AssertionError behaved different than assert(0) the first was ignored, while the second did print the stacktrace (With <dtml-var error_tb> in standard_error_message) thomas -- Thomas Guettler <guettli(a)thomas-guettler.de> http://www.thomas-guettler.de

Does UndoPack.pat from http://collector.zope.org/Zope/875 work with 2.5.1?
by Sven Rudolph 11 Apr '03

11 Apr '03

Hello all, I'm running zope-2.5.1 (Python-2.1.3, Linux) and just ran acroos the bug described in http://collector.zope.org/Zope/875. It says the patch works with 2.6.1. Is there a chance to apply it to 2.5.1? (I guess not :-( ) Thanks in advance Sven Rudolph -- Sven Rudolph, Programmierer Medical Tribune Verlagsgesellschaft mbH Unter den Eichen 5, 65195 Wiesbaden Tel.: 06 11 / 97 46 25 2

zope + apache + rewrite
by Ruslan Spivak 11 Apr '03

11 Apr '03

Hello, zope users. I need help. i have apache + zope + VHM configuration: <VirtualHost www.is.lg.ua:5000> ServerName www.is.lg.ua RewriteEngine On RewriteRule ^/(.*) http://192.168.1.1:6080/VirtualHostBase/ http/www.is.lg.ua:5000/is/VirtualHostRoot/$1 [L,P] ProxyVia on </VirtualHost> In root of zope i have /is folder. All this works, but in apache /cgi-bin directory i have irc.cgi script and i need to call www.is.lg.ua:5000/chat so that www.is.lg.ua:5000/cgi-bin/irc.cgi will be called. I tried 'ScriptAlias /chat /cgi-bin/irc.cgi' inside VirtualHost, but that doesn't work, because all mapping goes to zope, so i need probably the rewrite rule, but dunno how to make it work. Maybe you can help me with that? Your help is very, very appreciated. Thanks in advance, Ruslan

Reverse Aquisition!
by Mark Stangroom 11 Apr '03

11 Apr '03

I know aquistion in Zope works it way up the tree until it reaches the root so you can embed one document in another when its higher up the tree. Is it possible to do this in reverse so that i can embed a document which is in a sub directory lower down the tree? Hope this makes sense! Thanks Mark Stangroom

Maik, Ed, Thanks for the help. It took a bit of tweaking, but basically Maik was right. So this now works... <dtml-in mutein_id prefix=list> <dtml-if sequence-odd> <tr bgcolor='#7685bE'> <dtml-else> <tr bgcolor='#A5C7CC'> </dtml-if> <dtml-in expr="retrieveOligoData(mutein_id = list_item)"> <td align='center'><dtml-var mutein_id></td> <td align='center'><dtml-var molecule></td> <td align='center'><dtml-var vendor></td> <td align='center'><dtml-var vendor_id></td> ...... <dtml-else> <td colspan='15'>No data for <dtml-var list_item></td> </dtml-in> </tr> </dtml-in> One more question though...what does prefix=list do in <dtml-let> and why is it required? (this doesn't work if that snippet is removed) Why won't sequence-item work instead of list_item?

My first guess would be something like this: <dtml-in yourIdList prefix=list> <dtml-let result="getResults(id=list_item)"> <dtml-if result> <tr><td><dtml-var ID></td</tr> <dtml-else> <tr><td>No Data</td></tr> </dtml-if> </dtml-in> Cheers, Maik

Processing ZSQL results
by Mark Evans 11 Apr '03

11 Apr '03

Hi all, I should know this, but here goes anyway. I want to retrieve data from a table if an id that is submitted from a form is present. If I submit three id's, but only two are present in the table, two results are returned. I want to trap the missing id and display a "no data found" message. How can I do this? <table> <dtml-in getResults> <tr><td><dtml-var ID></td</tr> <dtml-else> <tr><td>No Data</td></tr> </dtml-in> This shows only the two results. The <dtml-else> is triggered only if none of the three ID's are present. Thanks, Mark Evans

ZRTChat content to external files?
by hpinson＠indepthl.com 11 Apr '03

11 Apr '03

Hi, I am using ZRTChat. This product, though very simple, really seems to work well. I've cleaned up the interface, and it may be viable in production. The only undesirable feature that I can see is that it fills up the ZODB with chat, that is, logs all chat messages internally to Zope. In a heavy chat situation, this would fill up Zope rather quickly. My question-- ZRTChat stores each chat message in a standard Zope folder object. Would it be possible to replace that folder with some sort of external file product that would allow these messages to be stored externally to Zope? What would that product be? I have used the ExtFile Product, but only to read files that are stored externally. I have no idea if it allows you to write external files. To all potential Zope chat product developers-- things I would like to see in future Zope chat products are threaded dialogs (each user displays as a different color), a list of who is available for chat, and private chat.
