Build-in functions

Trying to use the build-in python string functions like replace without success. I want to replace the slash with a dot in an URL (main/detail/form/index=> main.detail.form.index), but <dtml-let g="main/detail/form/index"> <dtml-var replace(g,'/','.')> </dtml-let> doesn't what i expect. It tries to call the object "replace(main/detail/form/index,'/','.')". Do i have to import the build-in functions? How? What's the way doing the replacement? with regards Axel

http GET messages

I have recently installed Red Hat Linux release 7.0 (Guinness). I added the Zope-zserver-2.3.0-1 and Zope-2.3.0-1 rpms from the 'Libc6 Contribs for i386'. It appears that all the requests are being logged in /var/log/messages. Is there some way I can change this to be something like /etc/httpd/logs/access_log? Here is a sample message: Mar 4 10:46:07 sprout ZServer[2311]: 63.93.99.139: - - [04/Mar/2001:10:46:07 -0700] "GET /p_/ZopeButton HTTP/1.1" 200 9515 "http://sprout.qantel.com/" "Mozilla/4.0 (compatible; MSIE 4.01; Windows 98)" Thanks in advance, Patrick

Path syntax
by Axel.Missbach＠t-online.de 11 Mar '01

Hi there, is there an easy way to change a path from slash-notation in python-syntax (main/sub/form =>main.sub.form)? I got an URL from the RESPONSE and some ascii-parts for the path. concating them in '/'-Syntax doesnt work. Manually changing the '/' in '.' is OK. with regards Axel

Re: [midgard-dev] ZPT, a next-generation template technology
by Ami Ganguli 11 Mar '01

11 Mar '01

Hamish, I first heard about this effort at OSDEM in February and it sounded promising then. If the design and implementation are easy to integrate I'd love to include it in Midgard 2.0. If it turns out to be a lot of effort, of course, we'll have to look at it closely and weigh the benefits, but the idea sounds solid. I don't have a lot of time to look at your proposals closely right now (although some other Midgard developers may), but I'll make sure we consider them before building our own templates for Midgard 2.0.

I can't find a way to call a form in an other subpath. Getting a variable "goal"="main/sub/form" from the calling-form. wanting to call it with <dtml-var "goal"> But it only prints the ascii contents on the screen. Is there a way to force an evaluation of the text? or how to do this job? with regards Axel

Batch Import?
by Jonathan 11 Mar '01

11 Mar '01

Hi all, What do you use to import a batch of files into Zope? Preferably fully automatic and scriptable, being able to import a mixed set of files and images and create objects for them, set properties? Batch import of images is what I need the most, preferably creating ExtImage objects. Anybody already built something like that? Found load_site and fsimport so far, am I overlooking something? Thnx! Jonathan

A developer from the Midgard project wrote to me as his only Zope-related contact to say that he was unable to join zope.org (in order to participate in the ZPT wiki). I've just tried creating a test account and got the error below: SMTPRecipientsRefused {'hbl(a)st-andrews.ac.uk': (550, 'relaying to prohibited by administrator')} --- Hamish Lawson ____________________________________________________________ Do You Yahoo!?

Image refresh
by Patrick 11 Mar '01

11 Mar '01

Hi, let's say I have a set of logos I want displayed in a certain cell in a table. So far, I have the following code for this <dtml-var standard_html_header> <table width=100%> <tr> <td> <dtml-var render-image_dtml> </td> <tr> ...... </tr> </table> And this works fine.Now, I want to change render-image_dtml so that new images are loaded everytime the page is refreshed by a certain user and so that the images change automatically if the same page is viewed for say, 5 minutes. Any ideas? Thanks, Patrick.
