Superuser domain authentication
by Stephen Harrison 07 Apr '00

07 Apr '00

I decided to tighten up security on our zope installations by putting domain restrictions on the superuser. However, I discovered a problem. If I access the server directly from within the allowed domain (port 8080) then no problem. But when accessing it through apache, I find that I cannot authenticate at all, no matter where I am connecting from. Is this a problem other people have had? Is there a solution?

ZODB and packing problem
by Yann COMBARNOUS 07 Apr '00

07 Apr '00

Hi, Well, I'm quite new to Zope, however this seems to be quite strange to me. When trying to pack the database, I get the following error (zope installed from source by root and run by root through start script): Error Type: IOError Error Value: [Errno 13] Permission denied: '/usr/local/zope-2.1.6/var/Data.fs' Traceback (innermost last): File /usr/local/zope-2.1.6/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/zope-2.1.6/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/zope-2.1.6/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: Fake) File /usr/local/zope-2.1.6/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/zope-2.1.6/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_pack) File /usr/local/zope-2.1.6/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_pack) File /usr/local/zope-2.1.6/lib/python/App/ApplicationManager.py, line 338, in manage_pack (Object: ElementWithAttributes) File /usr/local/zope-2.1.6/lib/python/ZODB/DB.py, line 522, in pack File /usr/local/zope-2.1.6/lib/python/ZODB/FileStorage.py, line 883, in pack (Object: /usr/local/zope-2.1.6/var/Data.fs) IOError: (see above) of course, I logged in as superuser, but I can't understand what's wrong. any idea? -- Yann COMBARNOUS E-mail: yann.combarnous(a)enst-bretagne.fr

JOB: CTO at Kendermedia
by Kevin Dangoor 07 Apr '00

07 Apr '00

Hi, Kendermedia is an Ann Arbor, Michigan-based media startup (ie we'll be producing content and cool sites for public consumption). We've got our business plan together and are currently working on getting venture capital, so this is an early stage opportunity for someone interested in working with a fun startup. We're looking for a CTO to lead a team of developers in putting together some really interesting web-based apps. These apps would be Zope-based, unless someone can convince me that there's a better way to do them. (I've been using Zope for a year now, and I don't think there's a better way.) Pre-VC, we will not expect much work from the CTO. After we get the VC, compensation will be commensurate with experience and will include a stock option package. If you're interested, please email or call me at 734-994-3735. Kevin Dangoor President Kendermedia http://www.byproducts.com - Humor and Novelties

How do I make an editable lists to fill a selection list?
by Ed Corrado 07 Apr '00

07 Apr '00

I currently have a form that allows me to select a choice of keywords to describe an Item that I am entering into a Zope object. (See http://phoebe.rider.edu:8080/Athena/entries/entry_addForm (more specifically, the Database Keywords check-boxes)). This is one of about 25 fields. I am currently generating the list of selection keywords using a dtml-in hard-coded loop as described in AlexR's How-to on selection lists (http:www.zope.org/Members/AlexR/SelectionLists). This works fine, but I would like to get this values from a list stored in another object/method/file/(?) that can be edited more easily (hopefully, via a web form. My question is, how should I begin to do this? Besides needing a way to call the list into my loop, I need to figure out how /where to store the list. Any starting points would be greatly appreciated. Ed Corrado

zope.org Members section
by Stephen Harrison 07 Apr '00

07 Apr '00

Is it just me, or is the Members section of the zope.org site always "down for maintenance"? It could just be misfortune that whenever I look at it it's down for some reason, but if it is the case that it is always like that, would it not be better to remove it from the menu? Better to not be there than to always be broken. Cheers, Stephen -- Stephen Harrison - stephen(a)nipltd.com New Information Paradigms - www.nipltd.com

The best way to set up Multiple Zopes?
by J. Atwood 07 Apr '00

07 Apr '00

Zopista's, I want to set up multiple Zope's on my Linux Box (6.1 running Apache with Virtual Hosts). The sites need to respond to different URLs and I think they should have different ZODBs. So... the questions are... 1) What is the best way to do this? (Proxy Pass, Zope.cgi, etc) 2) Has anyone done this and what has been their experience? 3) Are there any resource issues in terms of memory, processor, etc? Thanks, J

Hi, I have the following search in my zcatalog getting the unique values. But I would like to have them sorted as well. Is this possible ?? This one.. <dtml-in "artikler.artikel_catalog.uniqueValuesFor('kategorier')" sort=kategorier reverse> just results in the error: Error Type: AttributeError Error Value: 'string' object has no attribute 'kategorier' Regards ------------------------------------------------- Anders Holmbech Nielsen | Tlf: (+45) 70 22 56 00 Software Engineer | Fax: (+45) 70 22 57 00 Integrator Uniware A/S | http:/www.integrator.dk

Linuxworld's article (and a plea for a better documentation)
by Alessandro Bottoni 07 Apr '00

07 Apr '00

Have you seen this article? http://www.linuxworld.com/linuxworld/lw-2000-03/lw-03-penguin_6.html Here a quote: "It took me an awfully long time just to figure out how to start a new application. And I got stuck immediately after that. I could create various other Zope objects; one of my creations opens a connection to a database, for example, and another queries that database. But I still haven't figured out how Zope expects me to tie these objects together into a useful whole. This confusion on my part is a result of what I see as Zope's biggest problem: it has very little documentation on the mundane details of how to get started. There's plenty written about the innards of Zope and how to use DTML. But I'd give real money to have a handbook that just tells me, step by step, how to build the skeleton of an application using the Web interface. If you're an old hand at Zope and know of such a document available in hard copy or on the Web, by all means share the wealth and let me know." I have to agree with Nick Petreley (the author of this article): I had (and I still have) the same problems. IMHO, Zope urgently needs: 1) A good introductory guide (the existing tutorial, clearly, is not enough...) 2) A sample web site showing the most important features at work (this would imply the automated installation and configuration of the required software, like MySQL e.g.) 3) A set of task-specific guides (in this case, too, the existing documentation seems to be not enough for an absolute beginner...) I hope that the Zope development group will welcome this plea for a better documentation. ---------------------------------------------------------------- Alessandro Bottoni (Alessandro.Bottoni(a)Think3.com) Web Programmer @ Think3 inc.

Zope monitor - howTo ?
by Anders Holmbech Nielsen 07 Apr '00

07 Apr '00

Hi, I have read in some mails on this list that there is some util named "Zope monitor" that one can use to keep Zope running (and yes it crashes, two times the last 4 days). Is there some howTo somewhere or do anyone out there have some cool links I can go to ??

Backup / redundancy: Is data.fs enough ?
by Dimitris Andrakakis 07 Apr '00

07 Apr '00

Hi there, Suppose I have Zope properly installed on 2, not necessarily the same, servers. Say a RedHat on an i386 and an NT box. My goals are two: 1) to be able to backup my site regularly and easily and 2) to have one of them as a main server and the other as a redundancy server. So if the Redhat fails / crashes / gets hacked / whatever I want the NT box (or another Redhat, it doesn't matter) to serve exactly the same content. Will it be enough to keep the data.fs file and transfer it between the machines ? I thought that maybe this can't be done if the machines / OSes are different. Is this the case ?
