Are there any good references to setting up and using multiple Zope instances? -- John

Zope products and DTML
by Stephen Rudd 11 Mar '04

11 Mar '04

It's me again - and still having problems. I have a Zope product. It generates a load of useful information, but I wish to insert some DTML tags into the data that is output. I have no problem inserting these tags, but they will not render. Please could someone please explain how to encourage DTML to be parsed from the returned text. Thanks in hope and anticipation Stephen ----------------------------------------- Dr Stephen Rudd - genome astronomer Bioinformatics group Turku Centre for Biotechnology Tel. +358 2 333 8611 Fax. +358 2 333 8000 ------------------------------------------

.HTC (dhtml "behavior") files in Zope - problem and solution
by Paul Winkler 11 Mar '04

11 Mar '04

Here's one for the archives... Today I tried to add the png alpha-blending hack for IE to my zope site. This hack involves a DHTML "behavior" file, also known as HTC ("HTML Component") file, as described here: http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html I don't know squat about DHTML, so I just wasted most of today banging my head against the example on that site... ... wondering why it worked from the windows filesystem, and had no effect at all when uploaded to zope via FTP. I should have thought of this hours ago... the issue was content-type. You must arrange for the .htc file to be served from zope with a content type of text/x-component. text/plain works too. text/html does NOT work. -- Paul Winkler http://www.slinkp.com Look!

ZClass syntax question...
by Russell Fine 11 Mar '04

11 Mar '04

I'm new to developing Zope products and I'm trying to understand how I can add funcitonality to a ZClass. Specifically, What is the syntax to : 1. During intialization add an additional member to the ZClass (not a property, a member). For example, I'd like: instance.mymember=1 2. If the ZClass is an Object Manager, how would I create instance objects during construction (I'd like there to be default objects) ? Thanks Russell Fine

context bound to PythonScript even when not specified ??
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 11 Mar '04

11 Mar '04

Hello, I have an FS based PythonScript that looks like this: ## $Id: learningresourceslist_edit.py 152 2004-03-09 21:32:42Z jdoyon $ ## Script (Python) "learningresourceslist_edit" ##parameters=docpaths=[] ##title=Edit a Learning Resources List context.edit( docpaths=docpaths ) qst='portal_status_message=Learning+Resources+List+changed.' target_action = context.getTypeInfo().getActionById( 'edit' ) context.REQUEST.RESPONSE.redirect( '%s/%s?%s' % ( context.absolute_url() , target_action , qst ) ) Note the absence of ##bind ... So how come "context" still works if it isn't bound ? I was thinking at some point I'd clean up all unnecessary bindings from all my FS based PyScripts, but if it doesn't change anything ...

Moving objects via ZMI
by John Poltorak 11 Mar '04

Is it possible to move objects to a folder using the ZMI? I'm sure it must be doable, but it isn't immediately obvious how you can do it. -- John

Folder permissions
by John Poltorak 11 Mar '04

11 Mar '04

If I create a new folder, should I expect to be able to upload files to it via FTP immediately, or do I need to enable FTP access in some way first? Does it make any difference if that folder is within a Plone site? -- John

Acquisition from a DTML method in a subdirectory
by Jim Anderson 11 Mar '04

11 Mar '04

I'm running Zope 2.7.0 on a windows platform and I have a DTML method referenced in a subdirtory from a DTML document object. I want to run and external method from the DTML method, but Zpublisher is giving me an error message that the external method resource is causing a name error and the external method is not defined. My ZMI structure looks like this: root | A | Adtml_doc Aext_method B | Bdtml_method Adtml_doc has the following code: <dtml-var expr="B.Bdtml_method()"> Bdtml_method has code that calls Aext_method in A: Hi! <dtml-var expr="Aext_method()"> Bye! If I run the 'view' tab for Bdtml_method, the method runs as expected and if I assume that the method returns 'Good', my output is: Hi! Good Bye! If I run Adtml_doc, I then get the error message that Aext_method is not defined. If I place a copy of Aext_method in the B, and run Adtml_doc, I still get an error message. I was expecting that the Bdtml_method would find Aext_method by aquiring it from the A, but this does not seem to be the case. So it seems that calling a dtml method in a subdirectory does not acquire from the subdirectory or the current directory? Can anyone explain this? More importantly what is the proper way to call an external method from a dtml method being referenced in a subdirectory? Jim Anderson

Question about possible Data.fs corruption
by Ira Sher 11 Mar '04

11 Mar '04

hello all, I recently took over managing a zope site for a small nonprofit. I'm new to Zope and python, and the people who built the site don't have time to maintain it--it arrived in my hands with problems. If a certain kind of object (a "reader's guide") is added to the database, it breaks the site as soon as a person tries to view the new object. We have to restart from a previous version of Data.fs (running Zope 2.5.1, python 2.1, on Debian). I have a copy of the site on an OS 10.3 box with python 2.3 and Zope 2.6.4rc2--on this, the Zope server doesn't come down entirely, but does throw this error when I try to nav to the index page after an update: File /.../Traversable.py, line 106, in unrestrictedTraverse (Object: Zope) (Info: (['105586758764', 'Neela Vaswani', 'Authors'], '')) IndexError: string index out of range The file referred to is the new reader's guide object--I'm not sure why it's being called when I'm simply going to the site index page from an unrelated page, but this is no doubt integral to the problem. The folks who built the site and myself have peeled back this transaction numerous times. Things are packed before that. Nothing else causes problems. Thinking this could be a Data.fs corruption issue, I've run fstest, fsrefs, checkbtrees(none of which complain), and tranalyzer (which breaks almost immediately with "Not enough data left" back in transactions 3 years old). Planning to begin taking back enough transactions that things cease breaking, I've also used a verbose fsrecover to find recent transaction locations, and truncated a copy of the Data.fs file to these--this has created a POSKeyError at 0000000000000002 (site won't start, can't even set app = Zope.app() in python because it throws me an error there, too, so I can't view the object). And...that's where I stand. Any suggestions on how to handle this? I would appreciate any advice on either how to proceed, or rethink the problem. thanks in advance, ira
