Greetings, I use the following code in a site rule which works: <dtml-call "REQUEST.path.append('something')"> <dtml-return " 'ignored' "> But I want to use path.set or path.replace, which dont do anything? What am I doing wrong? Thanks, Paul Zwarts

What is this error?
by Dirksen 04 Jul '01

04 Jul '01

Hi, Recently, when people download video clips (over 20M each) from my Zope website, I get this error in the log file (not everytime but quite often): 2001-07-03T12:33:17 ERROR(200) ZServer uncaptured python exception, closing chan nel <zhttp_channel connected localhost:1557 at 1b72688 channel#: 321 reques ts:1> (socket.error:(10054, 'winsock error') [F:\zope\ZServer\medusa\asynchat.p y|initiate_send|211] [F:\zope\ZServer\medusa\http_server.py|send|399] [F:\zope\ ZServer\medusa\asyncore.py|send|282]) Despite the error visitors still get what they want. What does it mean? Does my ZopeDB have some health problems? How to get rid of it? Cheers Dirksen __________________________________________________ Do You Yahoo!?

IIRC, there was a discussion about exactly that on this list some days (weeks) before. The browsers don't have to send the credentials continuosly to every page on your domain, I think cheers, oliver

search dtml-tree
by Andreas Prlic 04 Jul '01

04 Jul '01

Hi! I want to provide a search interface a dtml-tree. Users should query all of the nodes of the tree and if their keyword matches to the title of the node, the tree should automatically be expanded to display this node What is the best way to do it ? e.g.: A tree about cars: if the table is not expanded it looks like: +cars if it is searched with "Opel" it should expand to: -cars | |- Ferrari | |- Opel Thanks for your help, andreas

boolean dtml solution!
by Leigh Ann Hildebrand 04 Jul '01

04 Jul '01

First, I want to thank everyone who sent email and worked on this problem with me. I've got a solution to report! If you'll remember, the original dtml method looked like this: <dtml-in expr="_[foldername].objectValues()" sort="bobobase_modification_time" reverse> <dtml-unless "_['id']=='index_html'"> <li> <a href="<dtml-var absolute_url>"><dtml-var title></a><br> </dtml-unless> </dtml-in> When I changed the unless to <dtml-unless index_hide>, it didn't work, because nothing was listed. After trying several Python scripts and other suggestions, I asked the very wise rdmurray of #zope if I should change the method completely. We'd already discussed the likelihood of this being a problem with acquisition; in reviewing my dtml method and other information further, he noticed something I'd been leaving out of my explanations. To quote: "Ok, my *guess* is that your problem arose from the fact that your index_html seems to be a DTML Document, since it has a property foldername. I'm guessing that when you tried the index_hide property experiment you naturally set index_hide on the index_html. But since it is a Document, anything called inside it acquires from it, so the hidden property got acquired." His guess was absolutely correct, and that was the problem. When I set my boolean dtml-unless, that's exactly what I'd done. Once that was figured out, the solution was easy: my index_html should always be a method, not a document. Once I corrected that, the problem was mostly fixed. I say *mostly*, because there was one thing left: with index_html now a method, I couldn't set the index_hide property on *it*, so it was showing up in my dynamic index listing. To fix this, and because I never need to list a method in my document indexes, I've excluded meta_type "DTML Method". So, here's the solution I'm now using: <UL> <dtml-in expr="objectValues()" sort="bobobase_modification_time" reverse> <dtml-if "meta_type!='DTML Method'"> <dtml-unless index_hide> <li> <a href="<dtml-var absolute_url>"><dtml-var title></a><br> </dtml-unless> </dtml-if> </dtml-in> </UL> Of course, one could solve this in other ways, and with a little tighter dtml, almost certainly. This solution works for me because I understand it and can modify it later if I need to. Many suggestions I got seemed great, except for being beyond my current capabilities. One of the standards I've set for my zope right now is that I not clip or use dtml or python that I don't understand well enough to modify, etc. Anyway, thanks again for all the assistance!

Overriding REQUEST.form
by Ragnar Beer 04 Jul '01

04 Jul '01

Howdy! In order to correct mistakes in a form I need to override parameters in REQUEST.form. E.g. a user types a wrong text in a field and I want to clear it prior to further processing. I tried (in an external method) self.REQUEST.set('whatever','') but this doesn't work (Zope 2.2.4). What can I do? Ragnar

manage_addMyZClass
by Mark James Adams 04 Jul '01

04 Jul '01

Hi Gang, I've created an external method manage_addMyZClass, basing my method off http://www.zope.org/Members/tazzzzz/addZClasses . However, whenever I call this external method on an ObjectManager derived ZClass, I get the error "Error Type: AttributeError; Error Value: this" on line 8, which just happens to be: self = self.this() I know that the this() call is needed so self equals the current context of the ObjectManager on which manage_addMyZClass is being called. Is there any other way to programmatically add a ZClass defined through the ZMI? And while I'm on that topic, what are the benefits/tradeoffs between using the ZMI to define products and using Python? I recently read the "A very minumal Product" How-To (http://www.zope.org/Members/maxm/HowTo/minimal_01) and noticed that this showed how write a manage_addMyZClass method in the context of a Python based product. The only reasons I've been given about defining products in the filesystems with Python vs. using the ZMI are being able to use external editors and CVS. Neither of these reasons are compelling enough for me, so why should else I use Python? I'm just starting a another Zope based site, and I have a slew of ZClasses to define. In the other (and first Zope based site) that I created and maintain I used only the ZMI to define ZClasses, so I'm pretty familiar with the process. Also, if I decide to go with Python based products, is there any easy way to turn a ZClass defined though the ZMI into a Python product? I'm not to worried about retyping code, but I've defined some fairly large propertysheets that would be annoying to recreate if I were to start from scratch.

Hi I have installed Zope version2.3.3 & ZEO1.0. I have copied the Data.fs files from the old Zope installation, which is Zope2.2.4, to the "var" directory under "Instance_home" in the new Zope. After starting zope, when opening the site, it gives a "Resource not found" error with following traceback. I am using Python1.5.2. Traceback (innermost last): File /export/usr/local/Zope3/Zope_software_home/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /export/usr/local/Zope3/Zope_software_home/lib/python/ZPublisher/Publish.py, line 187, in publish File /export/usr/local/Zope3/Zope_software_home/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /export/usr/local/Zope3/Zope_software_home/lib/python/ZPublisher/Publish.py, line 162, in publish File /export/usr/local/Zope3/Zope_software_home/lib/python/ZPublisher/BaseRequest .py, line 340, in traverse File /export/usr/local/Zope3/Zope_software_home/lib/python/OFS/Application.py, line 245, in __bobo_traverse__ (Object: ApplicationDefaultPermissions) File /export/usr/local/Zope3/Zope_software_home/lib/python/ZPublisher/HTTPRespons e.py, line 547, in notFoundError NotFound: (see above) Can anyone please tell me what could be the problem?

Hi folks, First, i would like to thanks all of you who provided me with the necessary help to get zope + mysql running, THANKS! I am facing a "problem": i added a mysql connection to my folder, zope is executing a begin + my query + commit. How may i stop zope from doing that. I want it only execute <my query>, nothing more, nothing else. Another problem: Just some of the query i run works when testing mysql connection. For instance, the following query does not work: select now() Looking at mysql log i saw zope exec the folloging: select now() limit 1000 How may i control how zope queries MySQL ?
