Is there a way i can place a checkbox in a form and have the script below change the properties only if the checkbox i checked. So if the box is checked, for instance, a headline will appear on the page, and if not, nothing will appear. Make any sense? Thanks in advance. <dtml-with "manage_clone(story_html,REQUEST['new_id'],REQUEST)"> <dtml-call "manage_changeProperties( headline=REQUEST['new_headline'], subhead=REQUEST['new_subhead'], story=REQUEST['new_story'], )"> </dtml-with> <dtml-call "RESPONSE.redirect( DestinationURL() +'manage_main?update_menu=1')"> ************************* Tom Scheidt www.falsemirror.com tom(a)falsemirror.com *************************

XSL for Zope - a bounty on this?
by morton＠dennisinter.com 10 Mar '00

10 Mar '00

A number of people have expressed a desire to have XSL support in Zope. The projects I am working on also seem to be needing the application of XSL, and whilst we can (and will) use some external XSL processor, it would seem that a 'cleaner' solution would be to have XSL support directly in Zope. I originally came to want to use Zope because I needed a tool that allowed the manipulation of a persistant tree of objects; my prototype was done in XML, but it needed persistance, an interface, and a programming language, hence the use of Zope. Even having only XPath support would be an extremely usefull way for packaging up simple 'queries' on the Zope database. Ive been looking around at the Python XSL implementations and the FourThought 4suite is looking pretty damned good, especially considering their goal of eventual ODMG 2.0 support. Zope desparately needs some standards compliance, even if only for the buzzwords. The question on my mind is: how much do other people want XSL in Zope? Im willing and able to put some $$$ up for a bounty on this. Is anyone else? I guess Id also like to heard what DC has to say about this; whether they are willing to have an external group contribute/merge a key technology into their codebase, and if they have any preferences about who this group might be. --------------------------------------------------------------- Heres what Uche Ogbuji of FourThought has to say about Zope http://www.pythonjournal.com/volume1/issue2/col-intranetpython/ The Zope Dope Digital Creations, fresh from a capital infusion, has given Pythoneers their first complete native Web application platform in Zope. the "Z Object Publishing Environment". Zope is similar in scope to Cold Fusion or SilverStream, but open-source and python-powered. Zope accumulates many bits and pieces of a successful Intranet site. It incorporates a database management system with object extensions (which, unfortunately, doesn't yet support the Object Database Management Group's specifications) as well as facilities for developing template Web sites, an application framework, a CGI mechanism for handling HTTP requests for objects, an HTTP and FTP server, and a comprehensive application framework to tie it all together. Z Templates are developed using a proprietary XML-based language, the Document Template Markup Language (DTML). ZTML does make some departures from the XML community in such areas as style-sheets, but it is hoped that Digital Creations or other contributors to Zope will work to close that gap. Zope is a synthesis of Digital Creations' many earlier products, such as Bobo, Principia and PCGI. Bobo has been especially popular among Python/Web programmers, and Zope looks poised to retain the tradition. If Zope can move a bit closer towards object database and XML-processing standards, it is likely to be quite popular outside the Python community as well.

Is Zope syntax inconsistent ?
by Richard Moon 10 Mar '00

I've hit the 'Zope Wall' again ! Can anyone explain why <dtml-if expr="AUTHENTICATED_USER=='zope'"> ZOPE ! <dtml-else> NOT ZOPE ! </dtml-if> <dtml-var AUTHENTICATED_USER> <br> Displays NOT ZOPE ! zope While this <dtml-if expr="tune_id=='Reel'"> REEL ! <dtml-else> NOT REEL ! </dtml-if> <dtml-var tune_id> Displays REEL ! reel Which is what I expected !

Re: [Zope] WorldPilot Calendar fixes and (UW) IMAP Options available

I tried this out, and yep, I'm getting somewhere, but not where I want to be. In particular, I'm not able to see any messages at all. And when I've got mail in the box, I get: readonly Sorry, a Zope error occurred.

Trees with DTML Methods?
by Art Hampton 10 Mar '00

10 Mar '00

http://www.zope.org/Members/anthony/tree-coding-tricks "How-To: Some Neat Tricks with dtml-tree" seems to imply that I can use trees on things other than ZODB objects. But I've been banging my head against the wall on this for some time, and I can't figure it out. Here's what I've got: An index_html document: <dtml-var standard_html_header> <dtml-call "REQUEST.set('eid', '1000')"> <dtml-tree id=eid branches_expr="GetEmployees(eid=eid)"> <dtml-var eid> </dtml-tree> <dtml-var standard_html_footer> A DTML Method called GetEmployees that returns test data: <dtml-if "eid == '1000'"> <dtml-return "[1001, 1010]"> </dtml-if> <dtml-if "eid == '1001'"> <dtml-return "[1002, 1003]"> </dtml-if> <dtml-if "eid == '1010'"> <dtml-return "[1011, 1012]"> </dtml-if> <dtml-return "[]"> What I get is an infinitely expanding tree of two pairs of 1000's: - 1000 + 1000 - 1000 + 1000 - 1000 + 1000 + 1000 + 1000 What I don't understand is how the stuff from branches_expr is supposed to change things around. And, not coincidentally, that seems to be the problem with this code.... Thanks for any help.

kind of variable in a document
by Laurent Chane-Chuen-Kee 10 Mar '00

10 Mar '00

Hello, I am trying to display a sequence of numbers with next to each of them the cumulated value of the previous ones. Thus, I was trying to declare a variable buffer to add at each cycle the value of the new number. But I can't figure out how to create a variable. Can somebody tell me how to declare such variable?

External Method to view ZSQL Record
by Joseph A. Archer 10 Mar '00

10 Mar '00

To all Zopists, I would like to use an External Method to access a record field from a ZSQL method by referencing another field in the record. If I set the External Method up such as: def viewfield(self,reference_field,search_value,field_value): where: reference_field = So that I can tell it the field I want to reference search_value = The value of the reference_field to query field_value = The value of the returned field, that I was looking for Do I use a "return" or a "result" or something else? I still don't have a handle on python yet, so I'm not sure what to put on the second line of the method. Thanks for all the help so far, and thanks for the help on this, in advance. virtually, Joseph A. Archer IT Coordinator Facilities Management James Madison University archerja(a)jmu.edu
