tree traversing & publishing
by Milos Prudek 28 Nov '00

28 Nov '00

I do not quite understand how Zope traverses a tree. I created "ZooExhibit" Z Class within ZooExhibit factory, and "ExhibitProperties" prop.sheet within that class, with an "animal" property. I made association between "Edit" name and propertysheets/ExhibitProperties/manage. I made an instance of the Z Class called "Rabbit" within Zoo folder. But when I access http://Zoo/Rabbit/propertysheets/ExhibitProperties/animal, I get an error "Missing doc string". Perhaps a similar problem: I created "BWE" product/Z Class, and on the Methods tab I created "pop" folder with a default "index_html". I created an instance of that Z Class called "BWE_inst" within a "BWE" folder. I can access "http://BWE/BWE_inst", but when I try "http://BWE/BWE_inst/pop", browser gives me Authorization failed. -- Milos

Factoids for supporting zope
by Spicklemire, Jerry 28 Nov '00

Albert said: > Our client thought that the recent VC money was about 1/2 what would > be needed to make it fly. My argument is that money is leveraged by > the active Zope community so a crux in my logic is how strong this > community is. The "1/2" the capital needed" part is a puzzling assumption. Is your client trying to map some business school model onto DC / Zope? If so, you are absolutely correct to point out that Zope is Open Source, and has excellent support from DC, and the Zope Community, which by the way includes lot's of other folks using Zope in real world enterprises. Most of all, it's very important for your client to understand DC's business model, and the fact that the new VC Capital will be used to scale DC to meet the already explosive demand for Zope based solutions. As a services company, no doubt DC has grown accustomed to meeting paycheck schedules by fulfilling the requirements of an expanding client list. The investment, based on the press release, etc., will be applied to making more of the same happen sooner. This is just my take on the public information, I have no ties to DC, other than as a Zope and Python fan (and hopelessly bedazzled groupie). If your client is sketchy about these details, it may be up to you to help them fill in the blanks. Have they checked out the Zope.org site, specifically Testimonials http://www.zope.org/Resources/Testimonials and Case Studies? http://www.zope.org/Resources/CaseStudies Some of these are old, but there are some pretty good hints there re. what folks have done with, and think about, Zope. Open Source in general can be disorienting at first glance. There are several "pages" out there with interviews where Paul Everitt answers questions about DC's business model, etc. Check these out: http://www.zope.org/Resources/Media http://www.bizjournals.com/washington/stories/1999/05/24/focus4.html and other articles here http://www.troubleshooters.com/tpromag/199906/_digcreate.htm and elsewhere on the Web.

Possible disaster upgrading to 2.2.4
by Jonathan Cheyne 28 Nov '00

28 Nov '00

Hi all, been very very foolish and didnt backup my entire zope installation prior to untarring the 2.2.x to 2.2.4 diff (binary) tgz. after restarting i get a message "couldnt import product.ZDbase" and one or two others, then screeds of oid errors then a start. But the site is a bit slaughtered because anything basedon a zclass I created durny work. even though it is there and not shown as brokwen itself. the only two shown as broken are zdbase and zdconfera. my zclass is only based on ZObject, CatalogAwareBase, _ZClass_for_Renderable so I am a bit stumped. when I try to list in magament view, the contents of any folder containing 1 or more instances of my zclass, the console shows things like: ------ 2000-11-28T14:37:38 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000k' Traceback (innermost last): File /home/zope/Zope-2.2.0-linux2-x86/lib/python/ZODB/Connection.py, line 448, in setstate File /home/zope/Zope-2.2.0-linux2-x86/lib/python/ZODB/Connection.py, line 213, in _persistent_load (Info: ) File /home/zope/Zope-2.2.0-linux2-x86/lib/python/ZODB/Connection.py, line 154, in __getitem__ (Info: ('\000\000\000\000\000\000\003\266', '(cExtensionClass\012ExtensionClass\012q\001(U\006ZDItemq\002(cZClasses.ZClass\012PersistentClass\012q\003cProducts.ZDBase.ZDiscussions\012ZDItem\012q\004cOFS.SimpleItem\012SimpleItem\012q\005tq\006}q\007(U\004iconq\010UWControl_Panel/Products/ZDiscussions/ZDTopic/propertysheets/methods/ZDItem%20/ziconImageq\011U\012_p_changedq\012K\001U\007__doc__q\013U\021ZDiscussions Itemq\014U\006_p_oidq\015U\010\000\000\000\000\000\000\002Lq\016U\011meta_typeq\017U\021ZDiscussions Itemq\020U\016propertysheetsq\021(U\010\000\000\000\000\000\000\003\271q\022(NU\010\000\000\000\000\000\000\003\265q\023Qttq\024QU\012index_htmlq\025cZClasses.Method\012MW\012q\026NRq\027}q\030U$_ZClassMethodPermissionMapperMethod_q\031(U\010\000\000\000\000\000\000\003\272q\032(U\016OFS.DTMLMethodq\033cOFS.DTMLMethod\012DTMLMethod\012q\034ttq\035QsbU\016manage_optionsq\036(}q\037(U\005labelq U\012Propertiesq!U\006actionq"U\025manage_propertiesFormq#u}q$(U\005labelq%U\010Securityq&U\006actionq\'U\015manage_accessq(u}q)(h%U\004Viewq*h\'U\012index_htmlq+utq,U\012ziconImageq-(U\010\000\000\000\000\000\000\003\273q.(U\011OFS.Imageq/cOFS.Image\012Image\012q0tq1tq2QU\022__ac_permissions__q3)U\011_p_serialq4U\010\0030\226a\274;\204\314q5U\012__module__q6U\031*73biqpAI2QDa2iKPitv57g==q7utq8t.N.'))

Zope mailing list doesn't work
by Milos Prudek 28 Nov '00

28 Nov '00

Today, I can't change my options for zope(a)zope.org. I went to http://lists.zope.org/mailman/listinfo/zope, and it says that the document has moved to http://lists.zope.org/mailman/listinfo/zope, ad infinitum. If youa are reading this then I can post, but I cannot read since I have disabled delivery a few days ago and now I can't enable it due to the above mentioned problem. Thanks for any help, and please mail me directly -- Milos Prudek

Building Zope within a Virtual Server
by Norman Khine 28 Nov '00

28 Nov '00

Hello, The new zope site seems to be running very well. I have a virtual server account on which I had previously installed zope 2.2.2 which was later successfully upgraded to 2.2.4, unfortunantly I had problems in setting up MySQLdb. I have now removed zope and python 1.5.2, re-installed python2.0, within my domain. Which is part of the larger domain. So my root directory is not in / but is in /usr/home/mydir/ , within which I have installed python2.0 I have changed the .login file so that the path for the new python installation is available through out my domain. So that when I type python2.0 at the # I can use the python interpreter, this seems to work OK. Therefore my question/s are: If there is python on the root machine as well as on the virtual servers, so that both python and python2.0 will run from the command prompt, will this cause problems when I install the new virsion of zope 2.2.4? Do I need to change any configurations to the makefile or setup so that zope knows it is using python2.0 and not the root installation of python, if so what will this changes be? I would like to configure the zope installation so that it is set up with an existing web server, currently Apache 1.3.12 as per your How-To by http://63.102.49.33/Members/maryniak/zope-on-suse64-howto by maryniak, but I am unsure as to where in the procedure I specify that I have python already installed? Do I need to specify this before? And finally, do I need the Python MySQLmodule extension be installed before Zope or after? Many thanks for your help Norman

Re: [Zope] html expertise anyone.

dtml as a server side scripting language is not going to change anything dynamically on your page. Maybe you mean DHTML. In IE everything is in the DOM and can be changed. Netscape is not thorough, and I don't think there is a hook that will change a.visited, et al. But you could try. IE has a links collection, like .images and .all

2.2.4 upgrade query
by Jonathan Cheyne 28 Nov '00

28 Nov '00

Further to my paniced posting earlier, I reinstalled 2.2.0, copied over my data.fs* and various products and everything fired up fine but i did one experiment (following on from Chris) - i didnt install zdiscussions. This resulted in major oids errors and my broken zclass as before/ install zdiscussions and bingo i am back in business. so. two questios: 1. why does my zclass appear to require zdiscussions when it is not based on it? 2. does 2.2.4 contain some parts of what was previously the standalone zdiscussions product? Is this an obsure backwarsd dependency break kindo of thing? I will stick to 2.2.0 for now, methinks. cheers Jonathan
