There should be a "dtml-in" argument to switch off this special treatment. If I had your problem, I would go for such a solution (extending "dtml-in"). It should be easier than to work around the special treatment in DTML and it would help the Zope community as a whole. If you do not want to go this way, I would suggest to put a feature request into the Collector. Dieter

There are lots of UserManagement products around. Maybe, this is covered. Search "zope.org". A "PAM" based user management product might do what you have in mind. Dieter

Are you interested in the "id" of "x"? Then the best thing is: <dtml-with x> <dtml-var id> </dtml-with> Dieter

Re: [Zope] adding properties to all existing docs

It is possible to change the base class but I would not do it (as it affects all Zope objects and your change is likely to disappear when you upgrade). You can automate Zope either internally or externally. Internally (via a method (DTML or Python)) you would use ZopeFind to list all objects that need to be updated and then iterate (dtml-in) over the objects to update. Externally, you would use "ZPublisher.ZClient". I would go for the internal solution. Dieter

There is a minor problem, if you like to put images in an "image" folder. But this is not related to filename extensions. Dieter

Re: [Zope] Zope Book Beta
by Tim Lynch 05 Nov '00

I wholeheartedly agree with Jason and Chris. I would very much appreciate a PDF version that could be easily printed, or read with Adobe's Reader. I hope there is no hesitation over making a PDF version available because of fear it will cut into sales of the bound volume. I think it would be just the opposite. I can easily think of examples (the original Tcl/Tk book comes first to mind) where the printed copy closed the sale of the bound volume for me. I'll be purchasing multiple copies of the Zope book for my shop regardless. (I tried to no avail to do a pre-order from OReilly's set yesterday :) Getting a chance to proof an early version and perhaps contribute to making it better only increases my desire to purchase the eventual publication. -- Tim Lynch Information Technology Section A.

404 Error on /p_/ Zope management images
by Andres Corrada-Emmanuel 05 Nov '00

05 Nov '00

Hi, I moved a "legacy" Zope-2.1.6 installation, and I'm finding that the management interface cannot find the usual Zope icons for "Folder", "DTML Document", etc. In addition, Zope no longer has the standard objects like DTML Document, Image, etc. in the Add Object list. All the installed products show up and existing folders and documents also appear. I'm completely baffled. Anyone seen this type of behaviour? -- ------------------------------------------------------ Andres Corrada-Emmanuel Email: andres(a)mamey.com Director of Technology http://www.mamey.com Mamey Phone: (413) 529-9993 ------------------------------------------------------ --

Greetings! I am graduation student and I come using the platform zope for development of systems directed to education. One of the main doubts when using zope, not only the syntax, but also as to use it to develop applications using methodologies (former UML). As to use concepts of Objects Oriented : inheritance, aggregation, dependence...? Using its it of management screen? yours truly -- ----------------------------------------- Douglas Daniel Del Frari ----------------------------------------- Acadêmico Computação - UNIJUÍ Brazil, RS ----------------------------------------- mailto:gaucho@detec.unijui.tche.br http://labinf.detec.unijui.tche.br/~gaucho -----------------------------------------

Cookies & Expiration
by Kit O'Connell 05 Nov '00

05 Nov '00

I'm trying to set up something like is used in the Zope Elvis tutorial, where it sets a cookie to show when you last visited the site, so that I can flag certain articles as 'new'. However, I'd like to have this cookie set to expire one week from the date of the current visit. i.e., if its 12:30 on 11/3 when a surfer visits my site, I want Zope to set their lastVisited cookie to expire on 12:30 on 11/10. Any ideas? Thanks, Kit
