Problems looping through Folders and Documents
by Adrian Esteban Madrid 09 Nov '99

09 Nov '99

I want to have two different menues: one with the Folders in the current folder and another with the DTML Documents again in the current folder. Here it goes what I've come up with (abridged, please don't laugh at my cut/steal-and-paste ignorance here):  <dtml-call "REQUEST.set('PFold', [])">  <dtml-in "PARENTS[0].objectValues(['Folder'])"> <dtml-let item=sequence-item> <dtml-unless "hasProperty('hidden') and hidden"> <dtml-call "PFold.insert(0, item)"> </dtml-unless> </dtml-let> </dtml-in>  <dtml-if PFold> <TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 NOF=LY> <dtml-in PFold> <dtml-with sequence-item> <TR> <TD WIDTH=98 BGCOLOR="#FFFFFF"> <A HREF="<dtml-var absolute_url>"> <dtml-if "hasProperty('nickname')"> <dtml-var nickname> <dtml-else> <dtml-var title_or_id> </dtml-if></a></B></font> </TD> </TR> </dtml-with> </dtml-in> </TABLE> </dtml-if> This works just great for the first objetive. Unfortunately, I try doing the same thing for a second time only with 'DTML Document' but it just loops forever (a Python thread uses up 99% of the CPU). I don't know. I've been playing with this all night and haven't been able to figure it out. HELP! -- Adrian Esteban Madrid Network Support, ATS Brigham Young University

Problems moving Product to Zope 2.1 site.
by Jay, Dylan 09 Nov '99

09 Nov '99

I have a ZClass based product on a Zope 2.0.1 site. I wanted to put this in an new Zope 2.1 site however I'm having problems. I've tried exporting the Product and then importing in into the Control_Panel of the new site. If its in xml format I get the following error  <p><a href="http://www.zope.org/Credits"><img src="http://cornfed.auslabs.lucent.com/p_/ZopeButton" width="115" height="50" border="0" alt="Powered by Zope"></a></p> </BODY></HTML> <PRE> Traceback (innermost last): File D:\Program Files\Zope2\lib\python\ZPublisher\Publish.py, line 214, in publish_module File D:\Program Files\Zope2\lib\python\ZPublisher\Publish.py, line 179, in publish File D:\Program Files\Zope2\lib\python\Zope\__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File D:\Program Files\Zope2\lib\python\ZPublisher\Publish.py, line 165, in publish File D:\Program Files\Zope2\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_importObject) File D:\Program Files\Zope2\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_importObject) File D:\PROGRA~1\Zope2\lib\python\OFS\ObjectManager.py, line 478, in manage_importObject (Object: ElementWithAttributes) File D:\Program Files\Zope2\lib\python\ZODB\ExportImport.py, line 216, in importFile File D:\Program Files\Zope2\lib\python\ZODB\ExportImport.py, line 318, in importXML File D:\Program Files\Zope2\lib\python\ZODB\ExportImport.py, line 283, in importFile TypeError: (see above) If its a zexp, I get an error saying that my ZClass does not support the copy operation. Is this 2.1 incompatibility problem or am I doing something wrong?

dtml syntax question
by Sam Gendler 09 Nov '99

09 Nov '99

If I have a form field name of "oname:required", in order to allow zope to force an entry in that field, how can I access the value of that field from javascript. The normal form.fieldname.value doesn't work, since it would look like 'form.oname:required.value' and javascript barfs on that. There must be a solution to this, anyone know what it is? --sam

I am interested in having a pull down menu with the different type of metadata for example title, subject etc, with a text field so one can search on a particular meta data type. Has anyone been able to do this? Daryl Moulder

Zope and Roxen - small byte limit on CGI?
by Tony McDonald 08 Nov '99

08 Nov '99

Hi all, After following Magnus' (http://www.zope.org/Members/magnus/Roxen) and Bills' (http://www.zope.org/Members/Bill/Documentation/RoxenZope) excellent HowTos on getting the Roxen server up and running with Zope, I've run into a little 'snag'. It seems that my Zope.cgi is only returning the first (small number) of bytes or so of CGI on pages where there are Roxen tags! On pages such as QuickStart I can have as much output as I like. Once I add a Roxen tag, things go awry. Some of the numbers that pop up are 352, 1301 and 2700 bytes. Is anyone else seeing this behaviour? This is Zope2.01 Solaris 5.6 and Roxen roxen_1.3.121 binary distn. I see Zope and Roxen as being a *very* interesting combination, eg Zope looking after fine grained authentication as well as management of users and content, whilst Roxen provides features that Apache can't get close to. The dynamic configuration of servers in Roxen (formerly Spinner) makes Apache look very pale. Tone

ZSQL batch inserts
by Mike Salib 08 Nov '99

08 Nov '99

Does anyone know how to perform batch inserts efficiently using ZSQL? For that matter, does anyone know how to simply perform a ZSQL insert on one row of data (where the individual elements are of different types)?

by Maarten Slaets 08 Nov '99

hi zopers, This howto (Using ZClient to Access Another webserver) by lstaffor explains how to connect to another webserver (for instance). i did exactly as explained on: http://www.zope.org/Members/lstaffor/ZClientMethod but when i try to add the external method in the web management interface i get this traceback: <traceback> Traceback (innermost last): File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope-2.0.1-src/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addExternalMethod) File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_addExternalMethod) File /usr/local/Zope-2.0.1-src/lib/python/Products/ExternalMethod/ExternalMethod.py, line 126, in manage_addExternalMethod File /usr/local/Zope-2.0.1-src/lib/python/Products/ExternalMethod/ExternalMethod.py, line 166, in __init__ (Object: webClient) File /usr/local/Zope-2.0.1-src/lib/python/Products/ExternalMethod/ExternalMethod.py, line 185, in manage_edit (Object: webClient) File /usr/local/Zope-2.0.1-src/lib/python/Products/ExternalMethod/ExternalMethod.py, line 194, in getFunction (Object: webClient) File /usr/local/Zope-2.0.1-src/lib/python/App/Extensions.py, line 204, in getObject (Info: ('/usr/local/Zope-2.0.1-src/Extensions/WebClient.py', 'WebClient')) SyntaxError: (see above </traceback> 1/ Is there something wrong with the source given on the website? (i did an exact copy paste, because i don't know pyhton yet. 'yet' because i will learn it, but now i have to finish this project rapidly otherwise my boss will finish me:-) 2/ Does anyone have the WebClient.py source of lstaffor? -- Maarten Slaets Web Developer KPNQwest Belgium http://www.fonky.com/vcard/MaartenSlaets/

Adding ZClass Instances Programatically -- the theory?
by Matt Jacobus 08 Nov '99

08 Nov '99

In the How-To written by tazzzzz it is explained that in order to add an instance of a zclass you need to make the following call: <dtml-call "YourZClass_add(_.None, _, NoRedir=1)"> As per the DTML doc, generally a folder or DTMLDocument is passed in as the first argument and the REQUEST is passed as the second. Would someone be kind enough to describe the theory behind passing in None as the client and "_" as the REQUEST mapping. In my code I end up using the following so that the new instance will be created in a subfolder: <dtml-with subfolder> <dtml-with "manage_addProduct['YourProduct']"> <dtml-call "YourZClass_add(_.None, _, NoRedir=1)"> </dtml-with> </dtml-with> But once again I'm not entirely sure *why* it is that pushing the subfolder's namespace on top of the stack and then passing the stack into the REQUEST argument for YourZClass_add results in the instance being added into subfolder. Intuition would tell me to simply pass in the subfolder and the REQUEST object as opposed to manipulating the stack directly and passing None and _. What I think I'm really trying to understand is how the createInObjectManager method resulting from: <dtml-with "YourZClass.createInObjectManager(REQUEST['id'], REQUEST)"> ends up with self populated with the correct folder. Many thanks for any insight. Matt
