Zope on a CD-ROM?
by spamfranke＠bigfoot.de 09 Jun '99

09 Jun '99

I'm trying to put my Zope app (1.10.2, Win NT) on a CD-ROM for demo purposes, using ZopeHTTPServer. I have a batch file whichs sets ZOPE_READ_ONLY before starting start.bat. It works fine when running from the harddisk. But on a CD-ROM I get the traceback below. Is the read-only mode not really read only? Stefan Traceback (innermost last): File "serve.py", line 100, in ? ZopeHTTPServer.main(args) File "D:\Programme\Zope\Koelnzope\ZopeHTTPServer\ZopeHTTPServer.py", line 500, in main start(module_file,host,port,threading,env) File "D:\Programme\Zope\Koelnzope\ZopeHTTPServer\ZopeHTTPServer.py", line 438, in start set_published_module(module_file,BoboRequestHandler,env) File "D:\Programme\Zope\Koelnzope\ZopeHTTPServer\ZopeHTTPServer.py", line 434, in set_published_module __import__(name) # to catch problem modules right away File "D:\Programme\zope\koelnzope\lib\python\Main.py", line 103, in ?

Tree tag and SQL methods?
by Alexander Staubo 09 Jun '99

09 Jun '99

I don't have a head for figuring this out today, but maybe somebody here can help me out. I'm thinking of exploiting the #tree tag in conjunction with one or more SQL method. Say I have a hierarchical-ish table with id/parent_id references, and I'd like to display this information in a nice collapsible tree. Possible? Possibly the expr= or branches_expr= arguments to #tree could evaluate the result of an SQL method, although it sounds to me like this would require one query per tree level. Possibly you could put the query results of the complete table in a temporary variable and evaluate on that? Anybody done something like this? -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin. Stop it.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_

Sqishdot bug and issues
by Michel Pelletier 09 Jun '99

09 Jun '99

After getting Tiny Tables to work with Zope 2.0 with ZODB2 (effectivly "1.11", it won't work with ZODB3) I installed the Squishdot product. Tres cool, as Morgan would say if she could say more than "bye bye". Only problem is I get an error if I try and use either of the two style themes that require Tiny Tables (I keep wanting to type Tyny Tables) Squishdot work with the basic layout, and tiny tables works fine by itself: Traceback (innermost last): File /home/michel/dev/Michel/lib/python/ZPublisher/Publish.py, line 255, in publish_module File /home/michel/dev/Michel/lib/python/ZPublisher/Publish.py, line 161, in publish File /home/michel/dev/Michel/lib/python/ZPublisher/mapply.py, line 154, in mapply (Object: manage_addSquishdot) File /home/michel/dev/Michel/lib/python/ZPublisher/Publish.py, line 98, in call_object (Object: manage_addSquishdot) File /home/michel/dev/Michel/lib/python/Products/Squishdot/Squishdot.py, line 1464, in manage_addSquishdot (Object: ApplicationDefaultPermissions) File /home/michel/dev/Michel/lib/python/Products/Squishdot/Squishdot.py, line 405, in __init__ (Object: bipity) File /home/michel/dev/Michel/lib/python/Products/Squishdot/Squishdot.py, line 195, in addTable (Object: bipity) File /home/michel/dev/Michel/lib/python/Products/TinyTable/TinyTable.py, line 58, in addItem (Object: bipity) File /home/michel/dev/Michel/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_main) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_String.py, line 514, in __call__ (Object: manage_main) File /home/michel/dev/Michel/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_tabs) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_String.py, line 514, in __call__ (Object: manage_tabs) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: _(manage_options=filtered_manage_options())) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_Util.py, line 309, in eval (Object: _(manage_options=filtered_manage_options())) TypeError: sequence index must be integer -Michel asking a question for once

[ANN] Zope in the low countries
by Rik Hoekstra 09 Jun '99

09 Jun '99

I proudly announce the birth of the usergroup for Dutch speaking Zope users. As they will probably mostly be from Belgium and the Netherlands (though the python newsgroup shows you never know :-) I called it Zope in the low countries (in dutch: Zope in de lage landen) The most important aim of the usergroup are: - to provide mutual assistence for Zope users on a regional level, - to be able to provide institutional decision makers with a guarantee that Zope is not some obscure and unreliable open source product but has more users and (hopefully) a great many succesfull implementations nearby. There is a discussion list coming (ZOPE-NL), but not yet operational. Details will be on the web site. To keep things focused, ZOPE-NL will be no local replacement for the regular zope lists, but a discussion forum for regional matters only. For the time being, if you're interested, please visit the (rudimentary) site at http://sw.fsw.leidenuniv.nl/cgi-bin/WebSite.exe/zopegroep Warning: it is completely in dutch. Rik Hoekstra

RE: [Zope] Iterating descendants of base Z Class, how?
by Alexander Staubo 09 Jun '99

09 Jun '99

Not really, because the same is accomplished (albeit surely less efficiently) using the syntax I cite below, but thanks for the suggestion -- I didn't realize objectValues() could accept a sequence. Maybe objectValues() should be augmented with a second parameter: acceptDescendants, default value 0. So,  ... would give project instances and any descendant instances of the Project class.

Thanks in advance for your help!!! My SETUP ----------------- Redhat 5.2 linux kernel (2.X ) Zope 1.10.2 (most stable version) Apache 1.3.4 MySQL 3.22.22 Thanks in advance for any help!
