Several times I've considered re-writing the tree tag from scratch since the cookie-state thing often seems to break down unless used in simple circumstances and the code in Treetag.py does seem a bit of a crufty mess (branches, branches expr, having to specify expr instead of just using "", no _ in expr, state in cookies (which can really go badly wrong :S), hard coded formatting of trees, etc) but the last time I put it off because I thought a major overhaul of DTML was imminent. (in that instance, I just used an external method to generate my tree since it was quicker and easier than making dtml-tree behave like I wanted...) I still think DTML needs a major overhaul but there seems to be a lot of resitence to this (maybe rightly so?) Perhaps it's time to just redo the tree tag in isolation then? What do people think? cheers, Chris

Unable to resolve 'Uncatalog...' error with PTK
by David Riggs 21 Aug '00

21 Aug '00

Having still more problems with this installation of Zope 2.1.6 and PTK 0.7.1... I've got several (seems that the number is growing) objects that appear in my ZCatalog, and show up on my site, but refuse to let me edit, move or delete them. Try to delete the object and get the following error: ------------------------------------------------------------------------------------------------------------------- Error Type: ValueError Error Value: Uncatalog of absent id '/portal/Members/demo4/D_Application' Traceback (innermost last): File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 401, in manage_delObjects (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 273, in _delObject (Object: ElementWithAttributes) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 226, in manage_beforeDelete (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 213, in unindex_object (Object: D_Application) File C:\PROGRA~1\DEV_PO~1\lib\python\Products\ZCatalog\ZCatalog.py, line 357, in uncatalog_object (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\Products\ZCatalog\Catalog.py, line 373, in uncatalogObject ValueError: (see above) ------------------------------------------------------------------------------------------------------- Updating the ZCatalog doesn't help, nor does clearing it out and re-populating it. I've searched through the mailing list archives and all the advice says to delete the ZCatalog, delete the trouble items, then undo the Catalog deletion. So I've tried to delete the ZCatalog 'SiteIndex' and then tried to delete the object and get this different error: ----------------------------------------------------------------------------------------------------------- Error Type: AttributeError Error Value: SiteIndex Traceback (innermost last): File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 401, in manage_delObjects (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 273, in _delObject (Object: ElementWithAttributes) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 226, in manage_beforeDelete (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 213, in unindex_object (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalObject.py, line 318, in getCatalog (Object: DemoPortalBase) AttributeError: (see above) -------------------------------------------------------------------------------------------------------- It looks like a similar problem was fixed on a recent version of Zope according to the history file, but so far all attempts at moving this project over to a more recent version of Zope/PTK have been less than successfull. As always, any and all comments/ suggestions/ help are very much appreciated...I've found this mailing list archive to be the most helpful documentation available so far. Thanks, Dave.

Newbie's ZWiki patch
by Jean Jordaan 21 Aug '00

21 Aug '00

Hi all I've overreached myself and patched ManagedMode ZWiki (love it, by the way), 'cause I couldn't stand the tag-abuse of the annotations, involving a table with explicit border- and color- specifications, all in the face of users editing the source of zwikipages. I've changed it to:: .... .... .... Of course, this presupposes a couple of CSS specs in the 'standard_zwiki_header' or someplace .. My changes to 'ZWikiPage.py' are marked 'njj:' in the following:: ### # If edit marker hasn't already been filled in by approval activity # then append one if s <> '': # njj: this is blatantly abusing 'bgc'. I could have changed # njj: 'bgc' everywhere to, for example, 'edit_class', assigning # njj: it the values 'wiki_edit', 'wiki_approved', and # njj: 'wiki_rejected' in the first place. text = text + '\n' + s + '\n' if bgc == '#99ff66': # njj: light green = 'Approved by '. text = text + 'wiki_approved">' + s + '\n' if bgc == '#ffcc33': # njj: light red = 'Rejected by '. text = text + 'wiki_rejected">' + s + '\n' # njj: text = text + '\n<table class=mm width="100%" bgcolor=' # njj: text = text + bgc # njj: text = text + ' cellspacing="0" frame="box" border="1"><tr><td>' # njj: text = text + s + '</td></tr></table>\n' Do any of you know of anyplace this is going to break? Does anyone think it's worthy of proper integration? I don't know if legacy browser support is an overriding issue here, since Lynx and W3, for example, certainly wouldn't do any better with the table than with the CSS .. AFAIK .. -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.1.6 on WinNT and W2K

I cannot compile Zope...
by Paul Hewitt 21 Aug '00

21 Aug '00

...on RedHat 6.2 (Zoot). I did not have problems compiling Zope 2.0 thru 2.2 on earlier versions of RH (eg, 5.2, 6.1). The problem seems to be with finding the include files, among them asm/socket.h. I have played around with LD_LIBRARY_PATH etc but so far have not gotten anything to compile -- not Zope, not ZDiscussions, etc. I have installed the binary version of Zope and this works fine, but that does not come with pcgi-wrapper compiled, for example. Any suggestions?

Bob, cd into the lib/python directory inside your Zope install... fire up the Python interpreter and do: >> import Zope >> app = Zope.app() "app" is a handle to the Zope "root object", and your folders and methods can be accessed via attribute lookup ala: app.aFolder or app.aFolder.aSubFolder.aMethod The rest is a small matter of programming :-) > -----Original Message----- > From: Bob Skaroff [mailto:rdskaroff@geocities.com] > Sent: Sunday, August 20, 2000 11:56 PM > To: zope(a)zope.org > Subject: [Zope] accessing data.fs outside of Zope > > > I have been trying to put together a little script to dump the > contents of Zwiki Pages into a text file.

accessing data.fs outside of Zope
by Bob Skaroff 21 Aug '00

21 Aug '00

I have been trying to put together a little script to dump the contents of Zwiki Pages into a text file. I can find the dictionary objects holding the meta_type and id of the Folder object containing the Zwiki site, but I don't know how to get to the Zwiki Pages inside it. This is what I'm coding: import Zope import ZODB db = ZODB.DB(ZODB.FileStorage.FileStorage('mydata.fs')) conn = db.open() root = conn.root() c = root._container c['Application']._objects lists the dictionaries, like ({'meta_type':'User Folder', 'id':'acl_users'}, {'meta_type':'Folder','id':'MyZwiki'}, etc.) How do I get to the Zwiki Pages objects inside MyZwiki ?

_setBasesHoldOnToYourButts()
by Hung Jung Lu 21 Aug '00

21 Aug '00

Hi, Can any hardcore Zope developer explain to me what this wonderful little method does? Please? Even if it is just pure voodoo. (I am looking for any voodoo magic that allows me to change a Z Object's ZClass dynamically. You heard me right: after an instance of Z Object is created, I want to change its ZClass from ZClassA to ZClassB. It's voodoo all right, but heck, voodoo is magic.) regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
