Loading Javascript Arrays with ZSQL Method
by Mike Doanh Tran 05 Feb '03

05 Feb '03

Hi all, It is possible to load a Javascript array using data from a ZSQL Method? Maybe some of you can give me a better way of doing this without using Javascript. I just want to create a dynamic drop down menu that users can select from and be able to display contents gather from a database query according to their selection. For example, if a user select category A. Then it will display all items for category A pulled from a database column. if select category B, then display all B items, etc. Thanks in advance, Mike --

Zope architecture diagram?
by Paul Winkler 05 Feb '03

05 Feb '03

I have often wanted a diagram I could show to other developers (and to myself, I confess) that's more detailed than http://www.zope.org/ZopeArchitecture . "Zope Core" is nice and abstract, but not helpful when I'm looking at the zope source and wondering "Who handles Today I came across http://www.zope.org/Members/SolKarma/ZEfive which is more detailed, but is also inaccurate on at least 3 points I spotted right away: * the ZODB knows nothing at all about Acquisition; AFAIK acquisition is handled at the Product level. * unpickling has nothing at all to do with compression, it has only to do with object persistence. * it's the ZODB, not ZPublisher, that pickles and unpickles things. -- Paul Winkler http://www.slinkp.com Look!

REQUEST variable is not being modified by Zope Python script
by Asad Habib 05 Feb '03

05 Feb '03

Hello. I am calling a Python script called 'incrementCounter' from a DTML Document and passing a variable to it called 'counter'. However, for some reason the value of this variable remains unchanged when control returns to the DTML method. I tested the Python script independently via the management interface and it works fine. The code for both the document and script is listed below. Any help would be greatly appreciated. Thanks. <dtml-call "REQUEST.set('rowLength', 6)"> <dtml-call "REQUEST.set('counter', 0)" > <dtml-in expr="aq_parent.objectValues(['Local File System'])" prefix="fileObject" sort="id" skip_unauthorized> <dtml-if "AUTHENTICATED_USER.has_role(['Local', 'Manager'], this())"> <a href ="/Personal/<dtml-var "getId()">">#<dtml-var "getId()"></a> <dtml-call expr="incrementRowLength(counter)" --> <dtml-var counter> </dtml-if> </dtml-in> increment = 1 counter = int(counter) + int(increment) return counter __________________________________________________ Do you Yahoo!?

Final version of Colorz released
by Max M 05 Feb '03

05 Feb '03

Hi all here is thi final version of the Colorz product. New stuff: - A few bug fixes - Proper security :-/ - You can choose a color by name for the main color (aprox. 500 named colors). http://www.zope.org/Members/maxm/productList/colorz/ Colorz is usable in many situations. * It can automatically generate a color sheme for an entire website from only one single color! * It serves as a single color repository for a website. * You can change the color scheme for a branch of a website, or for the entire site without having to change any code. * In systems like Plone, where changing the colors very often is part of site customisation procedure. Colorz makes it possible to change alle colors on a site by changing just the main color. Then the rest of the colors on the site will automatically adjust to this color by automatically generating an new color scheme. Following standard color theory. * When you are doing a draft layout, you usually skip back and forth between DreamWeaver, Photoshop and you browser. By using the Colorz you can make preliminary layouts a lot simpler. You can also test out which color scheme will be good for a main color. The Colorz product is also an interactive tutor of color theory :-) you can also try it out just because it is fun to play with colors. regards Max M

How to get permissions of a role?
by Lars Heber 05 Feb '03

05 Feb '03

Hello list, I've been digging in the list and in the sources for hours and days now, but I cannot find a solution - so, please help me out: I need to find out what permissions a role has. But I need the acquired permissions as well, so "permissionsOfRole('Owner')" doesn't work! Using getPermissions on the user object doesn't help because the user doesn't necessarily have the desired role. BTW: Is it wanted or a bug that Taking Ownership doesn't mean to get the local role "Owner"? I found a method "getRoles" in AccessControl/Permission.py which could perhaps suit my needs, but I don't know how to access it via PythonScript or DTML. Could anyone put me into the right direction, please?

Volatile variables Problem
by Antonio Beamud Montero 05 Feb '03

05 Feb '03

Hi all: Well, i have a serious problem... I have defined a variable inside my product that I refresh periodically via XML-RPC (every ~1 min). I need to maintain this variable volatile because ZODB grows to the infinite... The problem arises when a new conection is established an the variable value need to be shown. In some cases the query raises an AttributeException. Now I catch this exception, but this no solves my problem... Why the value of this variable is lost? How I can solve the problem? Thanks in advance... -- Microsoft merges technologies: Windows CE + Windows ME + Windows NT = Windows CEMENT ---- Antonio Beamud Montero Agora Systems S.A. http://www.agoratechnologies.com

Does zope still need a python compiled with "--without-pymalloc" ?
by Dario Lopez-Kästen 05 Feb '03

05 Feb '03

[Sent this to zope-dev, but realised it was off-topic there (no responses :-)] Hi, Well, the subject says it all. Why was it needed at all? I still compile my python --without-pymalloc from the pre-python-2.1.3 days when zope suffered from bugs in python. Thanks, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

Help w/ Date Sorting
by JBeard＠porternovelli.com 05 Feb '03

05 Feb '03

My Code: <span tal:repeat="item python: sequence.sort(container.news.objectValues ('DTML Document'), (('dateline','cmp','desc'),) )"> What this is doing: Using repeat to create a sequence of "DTML Docs" from my "news" folder. Then it's running a sort of those documents using the "dateline" field and sorting the objects from newest to oldest using cmp function. What my dateline field is: A property: type = string. They look like this "01-25-2003" and so on.... The error: It's returning output similiar to this: 01-13-2003 01-14-2003 01-24-2003 01-31-2002 01-31-2003 02-14-2002 02-26-2002 This is definitely not what I'm after > I'm after the newest date first and then on down. And I can't use the bobobase date b/c some documents get updated at different times (i.e a doc from 2002 could get updated today, but I don't want that to be on top). Any ideas?
