- Zope - Zope lists

Xron on Linux.

I would like to install this tool but as some of you know, there is a problem on Linux. On this message "http://groups.yahoo.com/group/zope/message/61753" says that I have to change the "rczope" and the "start" files. I made a "find" but I couldn't find it. Does somebody know where this file is? Thanks in advanced, Josef.

Namespaces
by Vitor Varalonga 12 Dec '01

Hi!!! I suppose this topic might not be mystery at all for all those who have been working with ZOPE for a while, but for me, as a beginner, it's really starting to look as a pain in the ***. The issue is namespaces. I've been dabbling across ZOPE documentation and help files, but somehow I never found an appropriate answer to my problem. Let me be more specific. Suppose I have all my files organized in the following directory tree: Work | |-- dmFiles | |-- sqlFiles | \-- pyFiles Consider that all my DTML Documents are located in the root directory (Work). DTML Methods, SQL Methods and Python Scritps are located respectively in the folders dmFiles, sqlFiles, pyFiles. So far so good... The problems start when I want to code one of the following situations: - call a Python Script (pyFiles folder) from a DTML Method (dmFiles folder); - call a SQL Method (sqlFiles folder) from a Python Script (pyFiles folder); What is correct code necessary to implement both this cases? Thanks in advance, Vitor Varalonga

RE: [Zope] stability of zope?
by Meilicke, Scott 12 Dec '01

Well, you have my curiosity now, so I dug around a bit. Partial output from uptime: Since 4/24/2000: System Availability: 99.8800% Total Uptime: 596d 0h:2m:30s Total Downtime: 0d 17h:10m:56s Total Reboots: 32 Mean Time Between Reboots: 18.65 days Total Bluescreens: 0 Note the Total Downtime includes scheduled downtimes, power outages (we had one that lasted for 5 hours last May), etc. The other output that I have not included indicates there were 9 "Abnormal Shutdowns". I hadn't noticed those, possibly because this machine hasn't been in production, just development. If I just look at the "Abnormal Shutdowns", mean time between reboots becomes 34 days. Not great, not bad. Mean Time Between Reboots includes multiboots due to multiple fix packs, security patches, etc. Yes, this is the downside of NT, but at least I could plan for it. I've had 23 planned shutdowns, 9 "Abnormal Shutdowns". So 32 reboots over 596 days isn't too bad for NT :) While I like linux better than windows (I've been using linux for 5 years), Zope on NT has been stable for me. Now, out of curiosity, I ran uptime on my two production servers, not running zope, but load balanced, so the site has higher uptime: server 1: Since 4/1/2001: (Last 255 Days) System Availability: 99.9606% Total Uptime: 255d 7h:53m:44s Total Downtime: 0d 2h:24m:50s Total Reboots: 42 Mean Time Between Reboots: 6.08 days Total Bluescreens: 0 Total abnormal shutdowns: 10 server 2: Since 4/1/2001: (Last 255 Days) System Availability: 99.9795% Total Uptime: 255d 9h:3m:39s Total Downtime: 0d 1h:15m:21s Total Reboots: 23 Mean Time Between Reboots: 11.11 days Total Bluescreens: 0 Total abnormal shutdowns: 3 Note these two are hosted at Exodus - lots of redundant power and bandwidth.

Newbie Security Question....
by Brandon Thompson 12 Dec '01

12 Dec '01

O.K. I am a little confused as to what is the best way to set-up security. Here is the scenario.. I want to create a Small Community/Portal. I want a member to be able to register with basic info, select a User Name and password, and hit Submit. Now assuming that I can get that to work. Now What? Do I use Zope security? And If I do, do I have to manually enter each individual "User" into a, lets say "Member_Users" folder? Is it possible to automate to process? I know that I am probably getting ahead of myself here, but just trying to think this all the way through.. Any help from the Zope Gurus, or anyone for that matter that know more than I out there, would be greatly appreciated! Thanks Again, Brandon

reduce() not available in zope?
by Stephan Herschel 12 Dec '01

12 Dec '01

Hello, Today i wrote a little (internal) python script for manipulating lists. I first tried in pure python using reduce() and map() and it worked just fine. So, i copied my code to the zope python-script and tried it there. It said something like 'reduce not known'. When i changed my code to work without reduce() it worked fine again. But i didn't need to remove map(). Is there an explanation? br, stephan -- Mag.

Handling of wrong URLS
by Tille, Andreas 12 Dec '01

12 Dec '01

Hello, I'm in the process of porting plain HTML pages to Zope. The bad thing is that the creators of the pages had the bad habit to spell their URLs with capital letters. Example: http://www.our-ugly-site.de/THIS/IS/AN/EXAMPLE.HTM I want to get rid of this and will replace it by: http://www.our-nice-site.de/this/is/an/example.htm But if users have bookmarks or something else they can not reach our new nice pages and so I wonder, if I could render a more informative page than Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: http://www.our-nice-site.de/THIS/IS/AN/EXAMPLE.HTM At first I could place a hint to the new convention. At second I wonder if I would implement a little script which converts the URL into lower case letters and suggest to try this one. Any idea how to do this? Kind regards Andreas.

adding zclass instances via dtml
by Cornelis J. de Brabander 12 Dec '01

12 Dec '01

Probably I'm overlooking something very obvious, but I can't find out what. I fail to add a zclass instance through dtml. I can add it in any folder I want using the management interface though, but the dtml fragment below raises an AttributeError with error value 'OLEenheid', which is the metatype of my zclass. Traceback see below. Can anybody put me back on track? <dtml-call "REQUEST.set('id', 'ovo002')"> <dtml-with "manage_addProduct['OLEenheid']"> <dtml-call "OLE_add(_.None, _, NoRedir=1)"> </dtml-with> Traceback (innermost last): File E:\zope\243\lib\python\ZPublisher\Publish.py, line 223, in publish_module File E:\zope\243\lib\python\ZPublisher\Publish.py, line 187, in publish File E:\zope\243\lib\python\Zope\__init__.py, line 226, in zpublisher_exception_hook (Object: broddel) File E:\zope\243\lib\python\ZPublisher\Publish.py, line 171, in publish File E:\zope\243\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: Eenheid) File E:\zope\243\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: Eenheid) File E:\zope\243\lib\python\OFS\DTMLMethod.py, line 199, in __call__ (Object: Eenheid) File E:\zope\243\lib\python\DocumentTemplate\DT_String.py, line 546, in __call__ (Object: Eenheid) File E:\zope\243\lib\python\DocumentTemplate\DT_With.py, line 133, in render (Object: manage_addProduct['OLEenheid']) File E:\zope\243\lib\python\DocumentTemplate\DT_Util.py, line 231, in eval (Object: manage_addProduct['OLEenheid']) (Info: manage_addProduct) File <string>, line 2, in f (Object: guarded_getitem) File E:\zope\243\lib\python\AccessControl\DTML.py, line 104, in guarded_getitem (Object: Eenheid) File E:\zope\243\lib\python\AccessControl\ZopeGuards.py, line 151, in guarded_getitem File E:\zope\243\lib\python\App\FactoryDispatcher.py, line 99, in __getitem__ File E:\zope\243\lib\python\App\FactoryDispatcher.py, line 102, in __bobo_traverse__ File E:\zope\243\lib\python\App\Product.py, line 137, in _product (Object: Products) AttributeError: (see above) Cornelis J. de Brabander ========================================== Department of Education, Leiden University P.O.Box 9555, NL-2300 RB Leiden +31 71 527 3422/3401 brabander(a)fsw.leidenuniv.nl ==========================================

User profile management product
by Benjamin Buffereau 12 Dec '01

12 Dec '01

Hi there, I need to manage user profiles, where "user" can stand either for an anonymous visitor or for an identified visitor. In other words, I need a session tracking product that: -allows the visitor to become a member, log in, log out, etc. -allows to store and retrieve visitor profiles. CoreSessionTracking can't do that, and I don't need a complete content management framework, as all I want to manage is user profiles. Anyone knows a product matching my needs? Thanks, Benjamin.

createInObjectManager and Zclass basics
by Jacob Singh 12 Dec '01

12 Dec '01

Where can I find good documentation on ZClass basics, I've read the tut and can set it up, but where can I find API reference from the functions it's calling such as createInObjectManager and managePropertySheet_edit(I think that's one) Neway, I need more detailed documentation and I'm really at a loss. Thanx, j
