DBField (REAL) in FORM-field (decimal problem)
by Robin Smidsrød 02 May '02

02 May '02

I'm using the Z DBI DA and when I have a database with a float/real value, it's always listed in exponential notation. What's the correct way to show it as a regular decimal (with dot or comma as decimal separator). -- Robin

Py script and manage_pasteObjects permission
by vsbabu＠vsbabu.org 02 May '02

02 May '02

Hello, I've a script that goes like #archiveit ids=['001','002'] return container.archives.manage_pasteObjects(context.manage_copyObjects(ids)) archives is a subfolder. Requirement is to copy some objects into a sub folder. Works pretty well from ZMI. I need this to work without authentication 'coz this is going to be called from another system over http (http://myzope:8080/mydata/archiveit) Even if I give Manager, Owner and Authenticated roles for the script, it asks for authentication. The error is like "you don't have permissions to run manage_pasteObjects in this context" I'm on Zope 2.5.0 on WinNT4. Any hints/help will be appreciated Thanks -vsb vsbabu at vsbabu dot org

Surely not in this day and age! I didnt mean the password that zope provides to oracle, but rather the passwords that your users provide to zope (via apache). Yes, they are plaintext.

abandonware and new.zope.org
by Milos Prudek 02 May '02

02 May '02

An idea for new.zope.org: encourage people not to abandon popular projects. Even very useful and well know Zope products get abandoned. Consider LoginManager. Both SourceForge and Freshmeat introduced rating according to "activity", which is probably the frequency of releases. This may not work 100% (some people may prefer to download software with lower frequency of releases as it may be deemed more stable) but it's a start. A more drastical approach would be tagging products that have not had a release in six months as "abandoned" in red typeface. Such products would stand out in a list of products, perhaps forcing the author to come out and say whether the product is doscontinued, but it would definitely make users better informed about the product status. Another approach would be to mark products "may be abandoned" if no release was published in six months, and "abandoned" if no release in 12 months. Just my idea. Propose something softer or harder, but IMHO some solution should be implemented. -- Milos Prudek

VHM and ProxyPass
by Matt Gregory 01 May '02

01 May '02

I am having a lot of trouble getting apache to work with zope and VHM. I have followed the howto, but the virtual host just hangs when I go to it... It doesn't appear to be a zope problem, as the virtual host seems fine. Still, I am currious if anyone knows anything about using proxypass with zope to make that work.

setting properties for multiple objects
by Russell Uman 01 May '02

01 May '02

is there any way with a vanilla zope 2.5.1 install to set a property for multiple objects at the same time? (say, all objects in a directory?) is there a zope product that does something this? thanks!

It is very unfortunate (and unnecessary) that DTML and Python Script use different security API's. Please file a feature request to the Collector. In Python Scripts, you would use: from AccessControl import getSecurityManager getSecurityManager().validateValue(value) In fact, that's what "SecurityValidateValue" does... Dieter

Form Data Needed in Second Form
by Dan Shafer 01 May '02

01 May '02

I have part of a Zope app written largely as Python scripts linking DTML forms that looks conceptually like this: 1. Form A gathers data and then as its action invokes a Python script. 2. Python Script 1 creates a new DTML document and updates its contents based on field data in Form 1. 3. Python Script 1 then uses RESPONSE.redirect() to open a second DTML form, Form 2. 4. Form 2 needs the name of the document Python Script 1 created as well as access to some or all of the data in the fields in Form 1. What is the best/right/only way to accomplish this goal? Seems like it should be straight-forward but I've played with several promising ideas that turned out to be dead ends. I'm getting a bit desperate. All help appreciated!

tal:repeat
by Tom Nixon 01 May '02

01 May '02

I am using this code to generate a navigation bar. I need to have a different bgcolor attribute on the td if we're already in that folder. In other words, I need to do tal:attributes="bgcolor string:red" but only where folder == here. The condition only applies to the bgcolor attribute so I'm not sure where it goes. Any ideas? <table> <tr tal:define="subfolders python:container.objectValues('Folder')"> <td tal:repeat="folder subfolders" bgcolor="yellow"> <span tal:replace="folder/title">Title</span> </td> </tr> </table>
