Hello! Can someone explain why this is not working? <dtml-var expr="[_.filter(lambda x: x not in [1,2,3,4,5], [2,3,4,5,2,1,2,3,5,6,7,8,9,0,8])]"> I get the following error: """ Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: filter """ the same error occurs if I try something like <dtml-let arg="[_.filter(lambda x: x not in [1,2,3,4,5], [2,3,4,5,2,1,2,3,5,6,7,8,9,0,8])]"> dtml-var arg> </dtml-let> Any help appreciated. /dario

[Q] zope starting problem
by YOON, Joo-Yung 05 Jun '01

05 Jun '01

Hi, I am currently experiencing a difficulty running zope (2.3.2). Before, the error message was like this. File /usr/local/zope/2-3-2/lib/python/Zope/__init__.py, line 110, in ? File /usr/local/zope/2-3-2/lib/python/ZODB/FileStorage.py, line 264, in __init__ File /usr/local/zope/2-3-2/lib/python/ZODB/lock_file.py, line 101, in lock_file StorageSystemError: Could not lock the database file. There must be another process that has opened the file. <p> (Zope was run from /etc/init.d/zope start during booting. And I can not log in, but the clients in the lan can do jobs of internet.) So I removed all init files of zope, and booted again. And then another strange thing shows up during booting like this. Starting deferred execution: atd (It still runs zope even though I deleted all init like files of zope.) Is there anybody that could help me understand these problems. My environment is as follows. 1. zope: 2.3.2 2. debian 2.2 (potato) 3. kernel 2.2.19 4. CPU: AMD486 DX4 100MHz 5. RAM: 48M Thanks, Joo-Yung

Re: Zope digest, Vol 1 #1440 - 45 msgs

Hello Zopesters: I am collecting resources for the ZPug.org site and I would like to journal the typical install on a common box and I would like some help with obvious tips, tricks, resources, etc, that will help someone install Zope on a box. Okay, I have a 300MHz K6-2 AMD box with 128M and 18G SCSI and I currently have it set up with a minorly customised Red Hat 6.2 box running apache and serving static and php pages with a mysql back end. I would like the step required to replace my /home/httpd/html stuff so that Apache resolves <http://www.zdev.org> to Zope 2.3.2 instead of PHP or static. So, lets start from scratch. Installing Zope. How to pre-prepare. How to ready, what to check for, and how to proceed as smartly as possible. This site will host a Zope Development Environment as well as MySQL and Mailman services. Okay. After install, how to I change the httpd.conf files so that I can run Zope through CGI -- but I would also like people who are checking my box to recognise that I use Linux, Apache, Python, and Zope! So that I can be part of the War against Netcraft's "where in the Web is Zope" ploy! Okay, so How should I go about it? When I install should I alias Products or mv them to /Products? Where should I install Zope? How do I install multiple instances? What should I and what shouldn't I do? What mistakes really mess up a person's day? What online resources would you not be able to live without, both pushed to my INBOX or visited or checked? Cheers! Chris PS: I would also like to be able to collect this info for sharing on <http://www.zpug.org> so please indicate whether this is or isn't okay -- can I quote you and use your name and give you credit? -- chris abraham, managing director <cja(a)beehive.de> <http://www.beehive.de> beehive North America, washington, dc, +1 202 548 0410 wk +1 202 478 0276

Is 2.3.3 coming?
by complaw＠hal-pc.org 05 Jun '01

05 Jun '01

Maybe I took a left turn at Albuquerque, but didn't I see betas for 2.3.3 out there? Now all I see in development is 2.4 alphas. Is there going to be a 2.3.3 sometime, or should we just apply the hotfix to 2.3.2 and wait for 2.4? That will teach me to go off to a conference for a while... Cheers, Ron

RE: [Zope] Using the Namespace binding
by Farrell, Troy 05 Jun '01

Did you try context.varname? Troy -----Original Message----- From: Lee Shakespeare [mailto:lee@webfoundry.co.uk] Sent: Tuesday, June 05, 2001 9:08 AM To: zope(a)zope.org Subject: [Zope] Using the Namespace binding Hi Folks. Can some explain to me how I access DTML vars from a called python script? From what I've gleamed from the Zope book, I can set the Namespace binding for the script to expose the DTML namespace, but I'm having problems accessing it. I've tried _.varname, which gave me an attribute error and _varname is an illegal variable name. The variable is accessible from the calling DTML method via dtml-var Cheers.

In search of a subtler logo/attribution.
by Ellis, Neil (FNB) 05 Jun '01

05 Jun '01

http://www.zope.org/Members/Ioan/QEportal The 'made with zope' icon used by QEportal seems a nicer logo to use on websites. Where did that originate and can we use it? The current Zope attribution button seems a little over the top for most websites. I have no qualms given credit where credit is due but the button is very large and would not fit in with many sites. Many regards Neil Ellis

WEBDav Problem With ZClasses
by Eric Roby 05 Jun '01

05 Jun '01

I have two ZClasses, one with base class of CatalogAwareBase and ZDTMLDocument, the other with base class of _ZClass_for_Renderable and CatalogAwareBase. ZInstances are created as expected, TTW. However, when I try to manage these ZInstances via a WEBDav client, the objects are not visible. My first thought was that this was a permission/roles mix-up. When I looked at the 'Define Permissions' tab for the ZClass, I was only given permission to add these objects. There was no way to add new permissions to either change, edit or delete for the class. I noticed that other classes (that I have successfully managed via WEBDav) have 'change' permissions. My question is ... is this the probable cause and if so how do I add a 'change' permission for the class. Or ... is this a side effect of the class being based on CatalogAware? I am quite stumped here so any advice would be greatly appreciated... Thanks EricGet more from the Web. FREE MSN Explorer download : http://explorer.msn.com
