again: install Zope under Solaris 8
by Jan-Thies Baehr 23 Oct '00

23 Oct '00

Hi, I just want to resume a thread from september. Has anyone else encountered problems installing Zope (in our case 2.2.2) under Solaris 8? And more important: Do you know a solution? Python is unable to import the ExtensionClass. I tried it from commandline (python 1.5.2 (#1, Oct 19 2000, 13:55:34) [GCC 2.95.3 19991030 (prerelease)] on sunos5) also and got the same Import Error: --------------- command and traceback following ---------------------------- [~/Zope-2.2.2] ./start Traceback (innermost last): File "/...../Zope-2.2.2/z2.py", line 554, in exec "import "+MODULE in {} File "<string>", line 1, in File "/...../Zope-2.2.2/lib/python/Zope/__init__.py", line 94, in import ZODB, ZODB.ZApplication, imp File "/...../Zope-2.2.2/lib/python/ZODB/__init__.py", line 85, in import sys, ExtensionClass, TimeStamp, cPersistence, Persistence ImportError: ld.so.1: /usr/local/bin/python: fatal: relocation error: file /mnt/disk2/homes/wklinik/Zope-2.2.2/lib/python/ExtensionClass.so: symbol PyImport_ImportModule: referenced symbol not found ------------------------------------------------------------------------------ Thanks, Thies Bähr. -- ----------------------------------------------------------------------- Jan-Thies Bähr Intelligent Visualization & Simulation DFKI GmbH Email: baehr(a)dfki.uni-kl.de D-67608 Kaiserslautern (Germany) Phone: +49 (0) 631 205-4565 -----------------------------------------------------------------------

Problems with sequence-item
by Taco Scargo 23 Oct '00

23 Oct '00

I get errors when sequence-item is being called to list the contents of a folder E.g. <dtml-in "(1,2,3)" reverse> <dtml-var sequence-item> </dtml-in> correctly outputs 3 2 1 When I do <dtml-in "folder.objectValues()"> <dtml-var id> </dtml-in> it correctly outputs all ids in the folder. But <dtml-in "folder.objectValues()"> <dtml-var sequence-item> </dtml-in> will fail with an error Error Type: AttributeError Error Value: __call__ What am I doing wrong ?

First, sorry for my (nearly) full-quote, but I think it makes this discussion more readable. To your question, from my testing (I did this with column names only, but I suspect the same behavior for table-names), postgres is case sensitive, but - as I wrote - in another sense. If you don't quote the column-names, they are converted to or interpreted as lowercased names. _But_ if the real name of the table/column is _uppercase_, it will not be matched by this lowercased name - in this sense postgres is case-sensitive. Postgres needs quoted names in sql-queries to respect capitalization (sp?) - and I couldn't <dtml-sqltest ...> get to generate them. This was a major problem for me, because I had to work with a bunch of tables which were exported from foxpro and dbase, and their names were uppercased in the process. cheers, oliver

ZCatalog question
by olpa＠sybcom.de 23 Oct '00

23 Oct '00

Hi Folks, i have a ZCatalog over a bunch of items with attributes A and B. Now I want to search all elements with attribute A set to value 1 and AT THE SAME TIME with attribute B set to value 2. So a sort of AND combination with two different attributes. How to do ? Regards oliver --- "All language designers are arrogant. Goes with the territory..."

> MySQL is case-sensitive over table names, so MERCHANTPAYMENT is not the > same as merchantpayment. > Other databases (Postgresql, Informix) are not. > Perhaps the Access/ODBC interface hides the case-sensitivity while the > direct ZMySQLDA does not ? Hmm, I'm not very clear about differences between handling of (table, column) names in sql-databases, but postgres IS case sensitive (in some sense). Few days ago I wrote to messages to this list describing my problems with postgres and capitals in column-names. The handling of these will render <dtml-sqltest ..> useless, because it doesn't quote the name of the vars. I that case postgres will not respect capital letter (will turn them lowercase) but also won't find the column which name is written uppercase. I think it would be usefull to collect the behaviour of different databases and try to find a solution which will work with all of them. The solution we have now clearly doesn't do that. cheers, oliver

Working with versions
by brocken22＠gmx.de 23 Oct '00

23 Oct '00

Hallo, I've got a question concerning versions. The working with versions in the management screen is obvious to me, but what about hiding the management-screen and working with them. I want to add ZClasses programmatically but some users should only be able to add them after a Controller has checked that everything is o.k. What are the right methods to use??? -- Sent through GMX FreeMail - http://www.gmx.net

RE: [Zope] NEWBIE: assign next free ID automatically
by Max Møller Rasmussen 23 Oct '00

23 Oct '00

This is untested, but an idea: <dtml-in "objectValues()[:-1]" sort=id reverse> <dtml-call "REQUEST.set('new_id', id+1)"> <dtml-var new_id> It is still subject to failure if 2 or more processes are writing an article in the same time. Furthermore it has to find and sort all the items in the folder. That could take a long time if there are lots of them. Maybe you should somehow insert a dtml-try until you succed in writing the article. Another aproach would be to have the folder with your articles have a property "lastID" and let "nexID" be a method that automatically would increment lastID end return it. Maybe it is possible to lock the lastID property?? >From: Patrick Koetter [mailto:p@state-of-mind.de] >What is it that I want to do? >I want to evaluate the highest ID (all are 'int') within the folder and >assign the next highest. >I'm sure this is easy to you...

HELP! Permissions problem, ZClass
by Eric Walstad 22 Oct '00

22 Oct '00

Help, pls! I have a ZClass that is functioning beautifully if I am logged in, but the anonymous user keeps getting prompted for a password. The problem occurs when my DTML method trys to create a new instance of the ZClass. I tried giving that DTML method a Proxy of "Manager" but that isn't helping. Any pointers? Thanks, Eric. Here's the traceback: Zope Error Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access CNewsItem.

Roxen & Zope, not working

I'm having problems running Zope on top of Roxen on a Win2k machine. They both run just fine separate but I can't make it work together.
