RE: [Zope] newbie batching question
by Farrell, Troy 21 Feb '01

21 Feb '01

If you are using a DTML Document, you will need to "get out" of it's namespace: <dtml-var standard_html_header> <dtml-with "PARENTS[0]"> <dtml-var "absolute_url()"> <dtml-in expr="objectValues('Image')" size=10 start=query_start> <p>display for any items found: <dtml-var sequence-item></p> </dtml-in> </dtml-with> <dtml-var standard_html_footer> A DTML Method doesn't require the with statements. Let me know if it still doesn't work.

Zope on an IBM S/390
by Ronald L. Roeber 21 Feb '01

21 Feb '01

Maybe others have done this but in case not, I have Zope (2.3) running on a linux virtual machine on an IBM System 390. It installed and started okay. The only product I've installed as of tonight is the latest PTK. I've been told that this is only a test environment and that it can go up and down at the pleasure of the system managers. I was wondering if anyone had something that they thought should be tested in this environment, something that would be beneficial to the Zope cause. Perhaps some load testing or performance measures that might be of use to the Zope community. If Zope could benefit, I'd be glad to let someone run some tests. Who knows, it may be doggier than some hot multi-processor Intel box...it did compile fast though. Ronald L. Roeber University of Nebraska rroeber1(a)unl.edu

Roadmap/LoginManager?
by Bill Seitz 21 Feb '01

21 Feb '01

It's great to have the Roadmap. Where are things going with LoginManager? The PTK/CMF uses it, right? If this is such a core product, does it make sense to change the core security model? Sorry if this is a stupid question. I'm a Zope newbie, looking at it more as a general development app server (as opposed to content management tool). And I'd like to learn the "best" way first, rather than having to learn both, pick one, then rewrite all my old stuff! __________________________________________________ Do You Yahoo!? Yahoo!

FSSession and calling DTML Methods in various ways
by Peter Bengtsson 21 Feb '01

21 Feb '01

I've got a DTML method that looks like this: Id: checksession <code> <dtml-if "FSSession.has_key('session')"> <dtml-return "1"> <dtml-else> <dtml-return "0"> </dtml-if> </code> Then a DTML Document: Id: index_html <code> <dtml-call FSSession> <dtml-if checksession> COOL! <dtml-else> Not so cool buddy </dtml-if> </code> This now works fine and the DTML Method (checksession) has FSSession in it's stacks thanks to index_html calling it as you should do. The problem is when I call checksession like a python expression. This fails: Id: index_html <code> <dtml-call FSSession> <dtml-if "checksession()"> COOL! <dtml-else> Not so cool buddy </dtml-if> </code> It in the latter case fails to find the FSSession object. In the above example, it looks easy to fix, but in reality it's a bit more complicated. What's the difference between <dtml-call someDTMLMethod_dtml> and <dtml-call "someDTMLMethod_dtml()"> ??

This should not be necessary. I would expect two alternatives: 1. Move the role up to the root folder and give it there to the user 2. Give the user a "local role" in "sub". > I'd imagine if a user is able to create proxy roles, he ought to be > able to assign that role to a dtml method he manages. ;-| >From a usage point of view, I would agree. It might make the security implementation more difficult however. I am currently not sure, how proxy roles and owner roles play together. If the effective roles are the intersection of the two (as I think they are) then removing the restriction would cause surprises on access. Dieter

Installation fails on NT (zope 2.3.0)
by Servaas Goossens 21 Feb '01

21 Feb '01

I downloaded Zope-2.3.0-win32-x86.exe from zope.org and have some problems installing it. The installer works fine for the first 97% and then freezes while installing some __init__.py. In the taskmanager there is a process "python.exe" that I am unable to kill. CPU is idle. I have WinNT 4.0 SP6 with IE 5.5 (and mozilla, by the way). Anybody have a hint?

VirtualHostMonster and URLs from ZCatalog
by Anselm Lingnau 21 Feb '01

21 Feb '01

I'm using VirtualHostMonster to map URLs like »http://www.strathspey.org/foo« to »http://www.our-isp.org:8080/strathspey/foo«. This works fine. Now I have started using a ZCatalog to index the DTML documents on my server, and I've added a »What's new« type of overview as per the »Ranges« section of the »Advanced ZCatalog Searching« how-to, by passing a suitable expression to the catalog object. However, the URLs in my result list (obtained via »catalog.getpath(data_record_id_)«) are all of the form »http://www.strathspey.org/strathspey/foo« (with an extra »strathspey« in the middle). What am I doing wrong? My Apache configuration contains the canonical rewriting rules ProxyPass / http://www.our-isp.org:8080/VirtualHostBase/ http/www.strathspey.org:80/strathspey/VirtualHostRoot/ ProxyPassReverse / http://www.our-isp.org:8080/VirtualHostBase/ http/www.strathspey.org:80/strathspey/VirtualHostRoot/ ProxyPass /misc_ http://www.our-isp.org:8080/misc_ ProxyPass /p_ http://www.our-isp.org:8080/p_ (linebreaks for convenience) and these work fine otherwise. The VHM resides in the root folder of my Zope 2.3.0 instance at www.our-isp.org:8080.

Exceptions and Python Scripts
by Chris Withers 21 Feb '01

21 Feb '01

Hi, I'd like to do a try...except in a Python Script. Unfortunately, it doesn't look like I'm allowed to import the exceptions module: Error Type: ImportError Error Value: import of "Exceptions" is unauthorized Is that intended? Where should I get hold of exception classes to use in Python Scripts? To make matters worse, a lot of Zope's internals still throw string based errors, so a very general except clause is the only way to catch them. Unfortunately, the only way to analyise those exceptions is to use sys.exec_info(), but using that in a python script always throws up an authenticatino box. Any ideas how to solve these problems? cheers, Chris

Upgrade woes and product import problems
by Aaron Louie 21 Feb '01

21 Feb '01

I'm trying to upgrade to 2.3.0b1 from 2.2.5b1... I installed the new version (according to the ZopeInstall HowTo, just to be safe), which started fine. I then shutdown Zope (2.3.0b1), moved the default var/Data.fs* files to a backup directory, then copied my old Data.fs* files over. When I tried to re-start 2.3.0b1, nothing happened. No debug message either. So I put the default Data.fs* files back in and restarted successfully. Fine, I thought, the database files aren't all that necessary. All the work I'd done on the previous version had been exported to a .zexp product export file, which were all subclassed from your run-of-the-mill ZClasses (image, file, folder, object manager, ZCatalog aware) and used DTML for all methods. No PythonMethods, no FSSessions, etc. So I put the .zexp file into the "import" folder and tried to import the product from within Zope. I got this error: Error Type: AttributeError Error Value: append Traceback (innermost last): File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/2-3/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/2-3/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_importObject) File /usr/local/zope/2-3/lib/python/OFS/ObjectManager.py, line 542, in manage_importObject (Object: Traversable) File /usr/local/zope/2-3/lib/python/ZODB/ExportImport.py, line 208, in importFile AttributeError: (see above) Here's my questions: 1. Why are my old data files screwing up Zope 2.3.0b1? 2. Why can't I import my product? Note: I also tried this with 2.2.5b1 --> 2.2.5, same errors. Any insights? Thanks, ajl
