dtml-Variablen in <dtml-in> loops?
by Philipp Robbel 27 May '01

27 May '01

Hello, I have a question regarding the use of dtml-Variables in the "start=" and "end=" sections of an <dtml-in..> loop. I have to do a calculation and I would like it to be in the "end=" section of a <dtml-in> loop. I can't get the following code to work: <dtml-in someFunction start=1 end=&dtml-Count;-&dtml-Value;> or: <dtml-in someFunction start=1 end="_.getitem('Count') -_.getitem('Value')"> My current workaround is to set a variable <dtml-call "REQUEST.set('TEMP',_.getitem('Count') -_.getitem('Value'))"> and use that Variable TEMP in my <dtml-in..>: <dtml-in someFunction start=1 end=TEMP> And this finally works. But is there a better solution? Can I do Variable-Additions/Subtractions within the "end=" Section of the <dtml-in..> Tag? Thank you very much, Philipp Robbel

Zope (ZServer) in parallel with Apache
by Chris Ryland 27 May '01

27 May '01

Is it easy enough to run Zope (ZServer, as I understand) directly on port 80 (without FCGI or PCGI through Apache), with Apache also running directly on, say port 81, and redirect all Apache-related calls to //www.mysite.com:81/... from the Zope site? Is this as straightforward as it seems? Have others done this? -- Cheers! Chris Ryland Em Software, Inc. www.emsoftware.com

If STUPID_LOG_FILE is working, Zope will write its startup messages to it, independently of Xron. So, from what you said, I guess you don't have it working yet. You can't do much debugging without either STUPID_LOG_FILE or running in terminal debug mode. I'd suggest you get the log working first. If you can't get it working with a STUPID_LOG_FILE environment entry, try the Frozen Logger product. What version of Zope?

The problem is not with the e-mail, but with > the Scheduler never seeming to send the darn thing. But when you view or trigger it you have Manager permissions. That's different from the Dispatcher environment which has the permissions of Anonymous User. -- Loren

Newbie question: http-cache, caching elements
by Fernando Fuente 26 May '01

26 May '01

hi, does anyone know how to cache objects like gifs by a http-cache? my problem is that i have a navigation (constructed via tables) that is set up and changes dynamically every time a link is hit. this table includes a small picture. i think with the standard http-cache i can only cache "finished" html sites. therefore the picture is loaded every time i click on links that have not been clicked on before. i would like to cache this special element explicetly. can it be done? thanks a lot, fernando

Newbie question: wysiwyg-like editors

hi all, does anyone know good wysiwyg-like editors that can be integrated into zope-sites. am thinking of providing an easy user interface for unexperienced redacteurs who should be able to create simple web-sites in zope, like they used to do with common editors.... cheers, fernando

(like <dtml-if ../spanish_default> do... ). There are several Zope products for internationalization/localization: Localizer, ZBabel, vary tag, etc. I think this is what you are searching for and its less expensive to use them than to code everything by yourself. You can get Localizer from http://sourceforge.net/projects/lleu If you nevertheless don't want to use an external Product: To check the existance of an object in the current folder whose name is stored in the string objName use: <dtml-if "_.getitem(objName)"> To check other folders you could either use getitem and the dtml-with tag or the following: <dtml-if "_.hasattr(folderObj,objName)"> Bye, Eric

There are two types of cache mangers in Zope: The 'Accelerated HTTP Cache Manager' and the 'RAM Cache Manager': The first one sets special HTTP headers to help proxies (e.g. web browser or squid) to cache your pages, images, etc. properly. This is the one you should use to cache your picture. The RAM Cache Manager caches finally rendered objects/pages in your computer memory to speed up presentation at cost of memory usage. Bye, Eric
