Hi! Please continue to reply to the list, so all readers benefit. On Thu, Jan 10, 2002 at 11:17:36PM -0500, Trevor Toenjes wrote: > thanks.

No. DTML Magic does more than that. <dtml-var xxx> (where xxx is a DTML object) is equivalent of <dtml-var "xxx(_.None, _)">. What is simpler to read and write?

11 Jan '02

I want to provide the visitor on my website a form like that: email: __________ | sendbutton to subscribe to a newsletter (exactly: to fetch the email address from the visitor and to write it into a single file) the newsletter will be manually generated. How can i do that exactly? Do i need a dtml-method for fetching the email address? How do i append the address to a file in the same zope-directory? -- thx in advance, Stefan Antoni ---------------------------- Mit Jan 9 18:39:19 EST 2002

Problem with parameter submission to Python Scripts
by Mark Simpson 11 Jan '02

11 Jan '02

Hi, I'm trying to get the following script to work in zope: for image in context.objectValues('Image'): if not image.hasProperty('original_id'): context.outputdir.makeThumbnail(image.getId()) Where outputdir is a parameter passed to script, and is called with makeThumbnails?outputdir=thumbnail where thumbnail is a folder in Zope. The problem is: context.outputdir.makeThumbnail(image.getId()) I need the object that is refered to by outputdir. For instance if I use: context.thumbnail.makeThumbnail(image.getId()) it works fine. I've tried getattr, getitem, but had no luck. Can anyone shed light on the correct way to do it? Thanks Regards Mark Simpson

python expression dtml-var rendering
by Trevor Toenjes 11 Jan '02

11 Jan '02

Why do <dtml-var mycontent> and <dtml-var expr="subfolder.mycontent"> render differently? <dtml-var mycontent> displays intended without HTML tags. But, <dtml-var "subfolder.mycontent"> displays as if it is a text file. 'mycontent' is a DTML_Document. For testing I copied the same file to 'subfolder'. But, <dtml-with subfolder><dtml-var mycontent></dtml-with> renders correctly. I thought this was the same as <dtml-var expr="subfolder.mycontent"> I assume this has to do with using a python expression, but surprises me in behavior. TIA for a quick refresher. -Trevor BTW, is there an HTML equivalent to fmt=structured_text? like fmt=HTML

(discuss) :mixed ZOPE and FrontPage environment?
by Randy Winn 11 Jan '02

11 Jan '02

We wish to migrate to ZOPE from our current 6000-page FrontPage environment. But we can't do it all at once. Any hints? Anybody do this sort of thing before? Any experience running a mixed environment, some pages ZOPW some nonZOPE?

Base classing ZClasses in Zope 2.5.0b2
by Peter Bengtsson 10 Jan '02

10 Jan '02

In Zope 2.4.x it was possible to have the Photo product as a base class. You have that long list with OFS:Folder, ZCatalog: CatalogAware, Photo: Photo and stuff. This doesn't exist in Zope 2.5.0b2. Why? How to go around it?

Zope and Apache
by Shilpa Shenvi 10 Jan '02

10 Jan '02

Hello, Yesterday I executed the virtual host instructions to interface zope and apache. Everything worked perfectly. However, some xrons eventually ran - there were some errors involved with that, and now I can not reach the page at all. When properly stopped and started, I never get the inital HTTP, FTP, and PGCI messages - but z2.py -D does execute. Has anyone else seen anything like this? Thanks, Shilpa

LocalFS and mega-uploads...
by larry_prikockis＠NatureServe.org 10 Jan '02

10 Jan '02

...from the "everything would be perfect if it weren't for those darn users" category... I'm running Zope 2.4.3 on Linux (RedHat 7.1 / Intel) and using the LocalFS product to allow users to easily upload/download files from their browser. For "normal sized" files (up to a few dozen Meg.) everything works as expected. However, with bigger files- in particular a 172 Meg file someone tried to upload- the system grinds to a halt as the server memory gets chewed up. I've seen a lot of discussions on this list and others regarding a previous bug in the cgi.py code that caused an entire file being uploaded to get stored in memory while transferring. It *sounds* like that's been fixed in the versions of python/zope I'm using though... However, my symptoms seem to match what was being described re: the previous bug... is there some patch I'm missing? Or is there any other solution other than asking users not to upload 172 Meg files??? thanks-- Larry p.s. the server has 256Meg of RAM. + Larry J.

Perhaps this modern sorcery especially attracts those who believe in happy endings and fairy godmothers. Perhaps the hundreds of nitty frustrations drive away all but those who habitually focus on the end goal. Perhaps it is merely that computers are young, programmers are younger, and the young are always optimists. But however the selection process works, the result is indisputable: "This time it will surely run," or "I just found the last bug." -- Frederick P. Brooks, Jr., The Mythical Man Month

Cool Zope Sites?
by Ronald L. Chichester 10 Jan '02

10 Jan '02

I got a new spot on FreeZope onto which I'm going to load materials for my students and fellow law professors. I'm looking for ideas to jazz up the site. Something cool, tasteful, but Zopish. Any cool sites out there running Zope. Sorry, but the Zope.com site is very plain (practical, but plain). I was hoping for something with a little more pazazz. TIA, Ron
