A web based list. A place people could put their names down as expressions of interest for developing, for testing etc, so that virtual teams can be easily and ideas can be thrashed out amoungst those interested. Those not directly involved can also get a feel for the progress of the idea. Also you can intergrate in something I'm about to work on for my site. This is a "bug-parade" type system for new features. Users have a limited number of votes which they can put on the ideas they would most like to see come to fruition. Also a neat way of organizing the contributed software section of the zope site, as this area has not nearly enough information.

Can't start server
by Paul Wolstenholme 13 Aug '99

13 Aug '99

I just read the devshed article on Zope and thought I would give it a try on my machine. I'm running: FreeBSD 2.1 Stable Python 1.5.2 Apache 1.3.6 Zope 2b3 I did not see any errors when I ran "python w_pcgi.py" but when "./start" was run I recieved the following errors: Traceback (innermost last): File "/usr/local/www/cgi-bin/Zope-2.0.0b3-src/z2.py", line 366, in ? import ZServer File "/usr/local/www/cgi-bin/Zope-2.0.0b3-src/ZServer/__init__.py", line 123, in ? from HTTPServer import zhttp_server, zhttp_handler File "/usr/local/www/cgi-bin/Zope-2.0.0b3-src/ZServer/HTTPServer.py", line 111 , in ? import thread ImportError: No module named thread If someone could point me in the right direction I would be very happy. /Paul - ________________________________________________________________ Paul Wolstenholme Simon Fraser University Centre for Experimental and Constructive Mathematics (CECM) Vancouver, BC Canada

hey guys I am writing an application that displays all the members of my database. Since I want to list a minimum of 15 on one page I want to highlight every second one, so they can visually be seperated. How would I do that? stephan -- Stephan Richter iXL - Software Designer and Engineer

ZServer lockups
by jason＠brahms.siteprotect.com 13 Aug '99

13 Aug '99

I'm experiencing occasional lockups of ZServer (currently being used in conjuction with PCGI and Apache). When this happens, I get no response at all from the http interface (Netscape eventually times out and says the document contains no data). I've looked in the ZServer log file, and the last entry corresponds to the last successful request that was served. When I kill z2.py, I get the following: Traceback (innermost last): File "z2.py", line 355, in ? zdaemon.run(sys.argv, os.path.join(INSTANCE_HOME, Zpid)) File "/home/controlpanel/Zope-2.0.0a4-src/lib/python/zdaemon.py", line 202, in run p,s = os.waitpid(pid, 0) KeyboardInterrupt Can any of the Zope gurus who have a better understanding of the Zope internals help to diagnose this problem? I'm using 2.0.0a4, and plan to upgrade to the latest beta this afternoon to see if that helps. Thanks, -jason ----------------- Jason Abate jason(a)hostway.com Hostway, Inc.

Let's assume you change it to: obj_id int4 parent_id int4 date datetime title varchar(40) body text What I'm about to suggest came to me by way of Anthony Baxter -- any cleverness it his. Any bugs are mine. Try: SQL Method sqlSelectChildren: --- select * from posts where  parent_id is NULL  parent_id =   --- Now the tree. This DTML gives a tree, with each node in the tree a link to URL1/main_view?obj_id=<the object's id> ---   <a href="/ViewPost?parent_id=">  </a>

Copy/Paste objects in DTML??
by Kevin Dangoor 12 Aug '99

12 Aug '99

Hi, I'm trying to do a mass conversion of old Folder objects into shiny new ZClasses, and I need to copy all of the subobjects of the Folder and paste it into the new ZClass. The subobjects are primarily Images. Here is what I was trying to use: [in the context of the old Folder] <dtml-if "objectIds()"> <dtml-call "REQUEST.set('cdata', manage_copyObjects(objectIds(), _.None, _.None))"> <dtml-else> <dtml-call "REQUEST.set('cdata', '')"> </dtml-if> [in the context of the new ZClass] <dtml-call "manage_pasteObjects(REQUEST['cdata'], _.None)"> I get an error stating that the object referred to in the clipboard was not found. Here is the last chunk of the traceback: File C:\Program Files\Byproducts\lib\python\DocumentTemplate\DT_Util.py, line 315, in eval (Object: manage_pasteObjects(REQUEST['cdata'], _.None)) File <string>, line 0, in ? File C:\Program Files\Byproducts\lib\python\OFS\CopySupport.py, line 198, in manage_pasteObjects (Object: CatalogAware) Copy Error: (see above) I don't think I've *ever* been able to copy and paste objects properly via DTML :( The reason I am calling manage_copyObjects(objectIds(), _.None, _.None) is that I don't want it to go to the management screens... I am trying to copy from a bunch of Folders to a bunch of ZClasses in one invocation of the Method. What am I doing wrong? TIA, Kevin
