Anyone have any clue why this would happen? Dek __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com

Migrating from zope-2.6.1 with DBTab to 2.7
by FLORAC Thierry 07 Apr '04

07 Apr '04

Hi, I'm currently working with zope-2.6.1, using DBTab product to split my database into several parts (all using FileStorage). I'd like to switch to zope-2.7, but after customizing my "etc/zope.conf" file : - Zope doesn't start when DBTab product is installed - if I remove DBTab, I can't access to my ZODB mount points because of an error message (This object from the DBTab product is broken !). Any solution ?? Thanks, Thierry

Problems accessing container properties at product creation time
by Roy Mathew 06 Apr '04

06 Apr '04

Hi Folks, I am trying to create a nested Zope product, and have trouble accessing properties from the container object... - I have a class MyFolder that extends Folder. - I have a class MyObj that extends (CatalogAware, SimpleItem, PropertyManager) - Class MyFolder is meant to contain several instances of class MyObj. I am able to create instances of class MyObj properly, and even have them be contained within MyFolder (using the inherited _setObject method of MyFolder). My problem is that I cannot seem to get manage_changeProperties to work on instances of MyObj at the time of addition (ie: just after I do the _setObject call). I have similar problems referencing methods/properties of MyFolder from within the methods of MyObject at the time of creation. However, after the addition has taken place, I can then through the ZMI, access or manipulate those same (and previously inaccessible/supposedly-non-existent) properties in MyFolder from within MyObj instances. What am I missing here. Is there anther step besides calling _setObject that I need to do, when the container is also a custom class in my product? Do I need to define my own __getattr__() for MyObj instances? I have tried to grep through the source code for various products, but am not seeing an obvious solution. Thanks, Roy Mathew. __________________________________ Do you Yahoo!? Yahoo! Small Business $15K Web Design Giveaway http://promotions.yahoo.com/design_giveaway/

specifying empty action for zmi tab
by zope＠netchan.cotse.net 06 Apr '04

06 Apr '04

I have the following class: class VirtualFile(Tabs, Implicit): "Wrapper around a file on the filesystem." [snip] manage_options = (({'label' : 'Info', 'action' : 'manage_main'}, {'label' : 'View/Download', 'action' : ''}, )) [snip] Let's suppose, I'm in zmi and access the management screen of an instance of this class via the following url: http://127.0.0.1:8002/Instances/tempo/ExternalFolder/EFExceptions.py/man age_main The link for the first management tab is just fine (href="manage_main"), but the second one (View/Download) is wrong, it's: href="http://127.0.0.1:8002/Instances/tempo/ExternalFolder". If I change the action field of 'View/Download' to 'index_html', the generated url will be okay again: href="index_html". What should I write in the action field to provide "http://127.0.0.1:8002/Instances/tempo/ExternalFolder/EFExceptions.py" as the url? Regards, Sandor

importing mail archives to Mailboxer
by chris h 06 Apr '04

06 Apr '04

Greetings; Installed mailboxer and it tests well. The next step is to move a number of mail archives into the 'boxer' Googling has turned up very little information about this limited to a discussion on imeme and a reference to a script on ActiveState. Was wondering if anyone has any references to review or read up on,as I honestly don't have a clue on how to get this done (as python skills are week) ie: importing an mbox archive >zope mia /ch

RE: [Zope] Re: Rendering DTML from string
by Samir Mishra 06 Apr '04

06 Apr '04

Thanks Dieter, that was helpful. I'm using Python code outside Zope to generate templates containing DTML tags. The tags are generated from (meta)data contained in a DB. The same modules are also generating a number of other related documents. As I said, it was a design choice, and, in hindsight, may be not the best one. Would you recommend 1. I move my Python modules generating the DTML code to External methods in Zope? 2. Create DTML methods stored within Zope from the DTML-tagged files (using manage_addxxx)? 3. Keep the external files and render the DTML in Zope? I'm working on trying to figure out which functions/classes within OFS.DTMLDocument and FileSystemSite.FSDTMLMethod I need for the rendering, if you have any advice, it will be appreciated. Thanks again, Samir. -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: Monday, April 05, 2004 11:41 To: Samir Mishra Cc: 'Small Business Services'; 'zope(a)zope.org' Subject: RE: [Zope] Re: Rendering DTML from string Samir Mishra wrote at 2004-4-4 08:38 +0400: >That's exactly what I have, DTML code in a text file.

It is worth to read them carefully: The above tells you that at place where a string was expected an ImplicitAcquirerWrapper" was found. It is almost always safe to translate "ImplicitAcquirerWrapper" to "Zope Object". Looking at your code, only the "routine" variable can be responsible for this behaviour and indeed the argument of "_[...]" must be a string and is (apparently) an object (probably a file object). Now to your special problem: rendering DTML code from a text file. * Why do you put DTML code in a text file? You should use DTML objects to store DTML code and not text files * When you really need a text file, you must convert their content to a DTML object and then render that. -- Dieter

INSTANCE_HOME is wrong when running as NT service
by Ng Pheng Siong 06 Apr '04

06 Apr '04

Hi, I'm building a ZServerSSL Windows installer for Zope 2.7.0 (and Plone 2.0). ZServerSSL adds a HTTPS_ServerFactory class in ZServer/datatypes.py. The factory's __init__ method does M2Crypto SSL stuff like the following: ssl_ctx.load_cert_chain('%s/ssl/server.pem' % INSTANCE_HOME) I've added code to write the value of INSTANCE_HOME to a temp file in __init__. When Zope is running as a Windows service, the value written shows that INSTANCE_HOME == Zope's installation directory, not the instance's directory. When I invoke runzope.bat or 'python zopeservice.py debug', INSTANCE_HOME has the correct value. This looks like a bug somewhere; I didn't see any obvious candidate after digging around a little. (I'm thinking to work around this by adding a parameter to my <https-server> section in ZServer/components.xml to hold the correct value.) Cheers. -- Ng Pheng Siong <ngps(a)netmemetic.com> http://firewall.rulemaker.net -+- Firewall Change Management & Version Control http://sandbox.rulemaker.net/ngps -+- Open Source Python Crypto & SSL

by klaus thorn 06 Apr '04

Will there be a binary update release package fromn 2.6.3 to 2.7.0 in the near future? If not: How do I update with 2.7.0 binary full release? The Documentation I found only covers updating binary releases with special update-packages. -- klaus thorn klaus(a)trillke.net
