That is what happens by default, when you include a DTML Method (and not a DTML Document). The DTML Method uses the same namespace as the calling document (unless you explicitely call the method; in this case, it uses namespace and client, you pass in).

adding a product
by Ulrich Wisser 10 Mar '01

10 Mar '01

Hello, I installed Yihaw and ran into the problem to add Yihaw items from my own dtml methods. From the HowTo (thanks Søren) I found some hints, but no solution. The problem is, that the items are not directly in the product folder, but instead are inside the YihawChannel ZClass. So here is what I try to do: <dtml-with "news.manage_addProduct['YihawDirectory']"> <dtml-with YihawChannel> <dtml-call "YihawNewsItem_add(_.None, _)"> </dtml-with> </dtml-with> I try to add a YihawNewsItem to my /news (Yihaw-)Folder. So far I was only able to get a security violation. Please find the traceback below. What do I do wrong? Thanks Ulrich Zope Error Zope has encountered an error while publishing this resource.

How to Defeat Acquisition
by Edmund Goppelt 10 Mar '01

10 Mar '01

I'd like to create a generic index_html for those folders that I haven't gotten around to creating a custom index_html. So, create the default index_html in the root directory and let acquisition do the heavy lifting, right? But, suppose I want to handle the inbetween case where there's custom text I'd like a folder to display, but not enough to justify writing a custom index_html? How can I get my generic index_html to display the contents of a DTML method guts_html if it exists in a folder, *without* acquiring any guts_html from parent folders? How do I defeat acquisition and have my generic index_html *only* look in the namespace of the folder it is called on? Here's the generic index_html I have in my root directory which unfortunately acquires guts_html from folders higher up: <dtml-var standard_html_header> <h2><dtml-var title></h2> <dtml-var folderlist> <dtml-var "PARENTS[0].guts_html" missing=""> <dtml-var standard_html_footer> -- Ed Goppelt

probably stupid: changing zstylesheet properties through dtml
by Danny William Adair 10 Mar '01

10 Mar '01

How can I programmatically change A ZStyleSheet attribute (ZSSAttr) through dtml??? <dtml-with css_content> <dtml-with Body> <dtml-call "background.manage_changeProperties({'value' : new_bg})"> </dtml-with> </dtml-with> won't do, it gets me an authentication request (whatever my role), telling me I am not allowed to access "changeProperties". It's not a ZClass, so there is no propertysheet I would have to define, is that right? Through the management screen, everything works fine, but I want to change only a few attributes from a _dtml method_, and I simply don't know how to do it. I've given the method every available proxy role, and still. I really believe that my problem is not ZStyleSheet-specific, but could anyone out there who has successfully done _this_ tell me how to do it? Thx in advance, Danny

Cyrillic Characters in URL
by Tim Cook 10 Mar '01

10 Mar '01

Okay, I'm baffled. I have a physician that wants to use FreePM (http://www.freepm.org:8080) with Cyrillic characters. I use names of people, drugs and other descriptors as object ID's "everywhere"! I thought that setting the correct character set would allow these characters to be used in URL's. He tells me that he can't create a folder in the management interface with a cyrillic character as the ID. Is this part of the Splitter.c problem? A lack of understanding on my part? His setup?

Zope Acquisition Idiom
by Edmund Goppelt 10 Mar '01

10 Mar '01

If I want to call another DTML method from within a DTML method, I use the following Zope idiom: My_dtml_method <dtml var fjdkjfkd> higherup.folder.other_dtml_method(_.None, _) ..... The docs says arg #1 is the client object I want the function to act on and arg #2 a mapping like the REQUEST object. So if I want the function to act on my DTML object why the _.None idiom? Why not refer explicitly to my DTML object by using 'this' or PARENTS[0]? -- Ed Goppelt

zope for intranet?
by Erik Hjelmås 10 Mar '01

10 Mar '01

Hi, forgive me if this is inappropriate (since I've just joined the list and briefly browsed the archive): Im in a working group with the purpose of suggesting a solution for intranet and internet for a college with 150 employees and 1500 students we are primarely looking for the following functionality: intranet: - calender (outlook type thing) - booking (meeting room, classroms, etc) - news publishing - sharing documents - email program - each employee should easily be able to manage his/her homepage and course pages - forms internet: - website search - forms (online application forms) + some of the same features as the intranet our current website is at www.hig.no and not very functional. The rest of my group is focused on selecting a commercial solution, which is very expensive, so Im trying to figure out if Zope, ezPublish or some other open source system is worth looking in to. Unfortunately, I dont have the time to download and try things out myself. Any thoughts, ideas and suggestions are greatly appreciated! /Erik ______________________________________________ veveve dått håige dått enno slæsj tilde erikhå www.hig.no/~erikh
