Zope Video Server
by lozinski＠jobmart.com 08 Nov '02

08 Nov '02

We are using zope to control a linux server with movable cameras attached. We can control the cameras to pan and tilt and zoom. We have a java client which displays a map. Click on the map, and the Camera points at that spot. Or click on the image to move the camera in the desired direction. Is anyone else doing this kind of stuff. Is there any software out there I can buy or get for free? Is anyone interested in such software? I think Video is a hot market, but I would love to know more about this market.

Re: passing lists as function parameters

> Or if I test the script with the following value for the parameter - > [1,2,3,4,5] - I get: I guess, you're using the "test" tab from the manage interface. The problem is that no matter what you introduce there, it's always being taken as a string. There is no way at that point to tell Zope that you're passing a list. To really test your script you have to create a dtml-method and call the script: <dtml-var "foo([1,2,3,4,5])"> Regards, Josef.

restrictedTravers-Problem (oder was auch immer)
by Tobias Herp 08 Nov '02

08 Nov '02

Hi, ich habe ein Problem, was mich gerade in den Wahnsinn treibt... Es geht um einen dtml-let-Block, in dem ich unter Verwendung des and-or-Tricks von Python eine Kaskade von Variablen definiere. So sieht's aus (Leerzeilen eingefügt wg. etwaiger Umbrüche): <dtml-let reference="REQUEST.get('reference','')" r_split="reference and reference.split('/') or []" page_path="REQUEST.get('page_path') or REQUEST.get('obj','')" refl="(r_split > ['',''])" imgid="refl and r_split[-1] or ''" galid="refl and r_split[-2] or ''" galSeed="page_path and restrictedTraverse(page_path) or None" galleries="galSeed and galSeed.getGalleries() or page_object ().getGalleries() or []" galleries="page_path and getGalleries()" the_gallery="galid and restrictedTraverse(galid,'') or None" the_gallery="the_gallery or (_.len(galleries)==1 and galleries[0])" galid="galid or (the_gallery and the_gallery.getId()) or ''" the_images="the_gallery and the_gallery.objectValues ('LMSGalleryImage')" > <dtml-if "1">  query string: <dtml-var "REQUEST.environ.get('QUERY_STRING', '').split('&')"> galid=<dtml-var galid> imgid=<dtml-var imgid> reference=<dtml-var reference> page_path=<dtml-var page_path> galSeed: <dtml-var "`galSeed`"> galleries: <dtml-var galleries> </dtml-if> Worauf es ankommt, ist die Variable galleries, die hinterher eine Liste von Galerien enthalten soll (spezielle ZClass), die wiederum natürlich Bilder enthalten. page_path wird korrekt übergeben und ist /der/Pfad/zum/Seitenobjekt (auch eine ZClass, die wiederum eine Methode getGalleries hat). Wenn page_path einen nicht-leeren Wert hat und auf ein gültiges Verzeichnis zeigt, müßte doch galSeed ein gültiges Objekt sein! Ich habe zwecks Debugging unmittelbar unter dem öffnende dtml-let-Tag ein paar Ausgaben plaziert. page_path hat den korrekten Wert; aber anstelle von "<acPage instance at 015C7578>" (getestet mit genau demselben Pfad in einem PythonScript) wird gar nichts ausgegeben. Was stimmt da bloß nicht? Hat restrictedTraverse irgendwelche Tücken, die mir einen Streich spielen?

Others beat me to the punch: read the Zope Book online. Also, have you at least got Zope installed and have logged into the Management Interface? Your membership/login needs may be solved by what Zope provides out of the box. I also have found Beehive's Book of Zope (ISBN 1-886411-57-3) a good introduction, but no one text is going to give you all the answers. You have to get your hands dirty and start building. I saw your post on zope-dev and one reply that said 'give up, learn Zope when you aren't under the pressure', but I disagree. I built my first Zope application (not just content) under deadline pressure, and it was a good way to learn "how do I do this with Zope?" Best of luck!

RE: [Zope] Replace files in a specific directory using pythonscri pt
by Ria Marinussen 08 Nov '02

Hi Heimo, Problem solved. Thanks for the directions. (I was looking for a source file named "File.py" not "Image.py". ) For those who are interested in the sollution: the source tells me: .... def manage_edit(self, title, content_type, precondition='', filedata=None, REQUEST=None): """ Changes the title and content type attributes of the File or Image. """ .... def manage_upload(self,file='',REQUEST=None): """ Replaces the current contents of the File or Image object with file. The file or images contents are replaced with the contents of 'file'. """ ... so for my problem I needed "manage_upload". Using "manage_upload" I could successfully edit the content of the object, but I couldn't upload the file-content I wanted. Untill I looked at my form header-tag and realized I forgot to include "enctype="multipart/form-data". Stupid me! So a simple "context.objectname.manage_upload(file)" (with file being the name of the file-object to upload, and objectname being the name of the zope file-object) did the trick.

Large file support in Python 2.1 ?
by Jean Jordaan 08 Nov '02

08 Nov '02

Hi all Apologies if this is a FAQ, a quick Google only turned up "Linux binary build includes Python 2.1.3 with Large File Support enabled compiled against glibc-2.1.3" from http://lists.zope.org/pipermail/zope-announce/2002-September/000884.html What I'd like to know is: what was done to compile that Python with LFS? And how do you check if it's in? After looking at http://www.python.org/doc/2.2p1/lib/posix-large-files.html I tried this:: jean@blommie Products $ getconf LFS_CFLAGS -D_FILE_OFFSET_BITS=64 which makes it look as if the environment is OK for compiling in LFS. But doing 'import types; dir(types)' doesn't show a 'LongLongType', only a 'LongType'. So it looks like this Python doesn't handle large files after all. Is there a recipe somewhere? -- Jean Jordaan http://www.upfrontsystems.co.za
