Zope 2.5.0 and Postgresql
by Markus Keller OrcaSoft 09 Feb '02

09 Feb '02

Hello, I have installed the ZPsycopgDA to access a Postgresql database. Everything (configure/make/make install/make install-zope) went fine but when I start Zope I receive the folloing error: 2002-02-09T15:45:24 ERROR(200) Zope Couldn't install ZPsycopgDA Traceback (innermost last): File /usr/local/Zope-2.5.0-linux2-x86/lib/python/OFS/Application.py, line 637, in install_product (Object: Zope) (Info: ZPsycopgDA) File /usr/local/zope/lib/python/Products/ZPsycopgDA/__init__.py, line 109, in initialize File /usr/local/Zope-2.5.0-linux2-x86/lib/python/App/ProductContext.py, line 94, in registerClass TypeError: unsubscriptable object I use Zope 2.5.0 and I have tested it with two plattforms: 1. FreeBSD with Zope and Python from the source 2. Debian 2.2 (Potato) with a pre-packaged Zope. On both Systems I receive the same error message. What went wrong? Thanks for your help. Sincerely, Markus

docs for invoking 2nd version of python
by Raymond Norton 09 Feb '02

09 Feb '02

I am using RedHat 7.2 with python 1.5.2.rpm. I want to use Zope ver 2.5 , which I believe uses python 2.1. I have been told I can install 2.1 on the same box, and tell Zope to use it. I have looked around for docs on this, but must not know my way around the archives. Any direction to the proper docs would be appreciated. -- Raymond Norton Little Crow Telemedia Network 320-234-0270

by Luis Martín Argañaraz 09 Feb '02

09 Feb '02

Hi, I have the next structure in my product My_Product /My_Product /www /page.dtml ... /img /my_img.gif ... /My_Pruduct.py ... I've define in My_Product.py a python class with the same name and inside this class I define what I show next: my_img = ImageFile('img/my_img.gif', globals()) In page.dtml I try to insert my_img with this sintax: <dtml-var my_img> This doesn't work. my_img appear as a broken image when I saw page.dtml This work when I use the same method to insert a piece of code DTML but doesn't work with an image. What I am doing wrong? Thanks in advanced Martin

zope 2.5.0 install problem
by Douglas Carnall 09 Feb '02

09 Feb '02

Hi, I'm running a Linux Slackware 7.1 box over SSH. I'm trying to get Zope 2.5.0 and CMF 1.2 installed so I can play physician beta-tester for Jon Edward's medzope project. Over the last week in my copious free time I have tried: a) the default binary (Zope-2.5.0-linux2-x86.tgz) b) downloading the source, compiling, and installing the source c) even downloaded and compiled Python 2.1.2 Whichever way I slice it, I can get Zope to run, but the startup script fails to complete, thus: > root@carnall:/usr/local/Zope-2.5.0-linux2-x86# ./start > ------ > 2002-01-31T13:26:43 INFO(0) ZODB Opening database for mounting: > '142200632_1012483603.415211' > ------ > 2002-01-31T13:26:43 INFO(0) ZODB Mounted database > '142200632_1012483603.415211' at /temp_folder > ------ > 2002-01-31T13:27:27 INFO(0) Zope New disk product detected, determining if we > need to fix up any ZClasses. > ------ > 2002-01-31T13:27:28 INFO(0) ZServer HTTP server started at Thu Jan 31 13:27:28 > 2002 > Hostname: carnall > Port: 8080 > ------ > 2002-01-31T13:27:28 INFO(0) ZServer FTP server started at Thu Jan 31 13:27:28 > 2002 > Hostname: carnall > Port: 8021 > ------ > 2002-01-31T13:27:28 INFO(0) ZServer PCGI Server started at Thu Jan 31 13:27:28 > 2002 > Unix socket: /usr/local/Zope-2.5.0-linux2-x86/var/pcgi.soc > ------ > 2002-01-31T13:27:28 PANIC(300) z2 Startup exception > Traceback (innermost last): > File /usr/local/Zope-2.5.0-linux2-x86/z2.py, line 688, in ? > IOError: [Errno 13] Permission denied: > '/usr/local/Zope-2.5.0-linux2-x86/var/Z2.pid' OK chown'd /Zope/var to nobody, and this fixed the problem.

However, I then see this message via my terminal: > ------ > 2002-02-08T10:23:12 INFO(0) ZODB conflict error at /manage_main (1 conflicts > since startup at 2002-02-08T10:19:54) Zope seems to be working OK, but presumably the script should finish and Zope becomes a background process? Have I ballsed up the permissions somewhere along the line? I can't find much on Slackware and Zope: maybe there's a configuration problem? What distro do most Zope people standardise on anyway? Any thoughts on this problem would be most appreciated: I'd like to have a nice solid setup before we start testing new products.

Compile Python
by ngterry＠easan.com.hk 09 Feb '02

09 Feb '02

Hi! I know this is Zope mailing list, but I would like to ask a Python question. I am new in Zope and Python, but I would like to compile Python myself in order to install Zope 2.5.0. What standard configure I should set in compiling Python for the purpose of learning Python and the requirement of compiling Zope? eg. ./configure --prefix=??? --??? I am using Debian 2.2r5, kernel 2.2.19. Sincerely, Terence Ng

Mods Attached Re: [Zope] Making ZClasses Inherit Subobjects from Bases
by Ross Patterson 09 Feb '02

09 Feb '02

Well, I ended up fixing the problem in my product, then I decided I wanted a way to do the same thing through the ZClass Subobjects management tab. So I made some changes to ZClasses/ObjectManager.py and ZClasses/dtml/subobjects.dtml and viola! It works beautifully. Now my question is this, should I submit these as patches at all? If so, having never done so before, how do I go about it? Following is the original message, and attached are the modified files. ---original message--- If I create a ZClass, ZC1, that subclasses ZClasses: ObjectManager and then create another, ZC2, that subclasses ZC1. As long as I don't save changes in the subobjects tab of ZC2, it will inherit the subobjects settings from ZC1. But as soon as I do save any changes, there is then no way to unset the subobjects and return it to the inherited subobjects. I think the way to do this would be to write a python method of my python base ZClass that calls the delClassAttr method from ZClasses.ZClass. But I can't seem to get this to work.

cutting/pasting
by Eckhoff, Damon 08 Feb '02

08 Feb '02

Hello, I'm trying to use manage_cutObject and manage_pasteObject from a DTML and cannot figure out which permission setting to change to map it to a role. Could someone help me, or point me in the general direction of some documentation on the subject? Thanks, Damon.

LFS
by Arenz, Ralph 08 Feb '02

08 Feb '02

Hellau, i' m trying to compile python 2.1.2 with the "LFS" to run on SuSe Linux 7.3. I' ve read about the large file support in the python docs. So i used the following export CFLAGS='-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64' OPT="-g -O2 $CFLAGS" and do: /.configure --without-pymalloc --with-threads ...that's works fine so i do "make test". ---------> The test for the large file support fails (platform does not have large file support) I' ve searched about python's and zope's mailing-archives but i found nothing which makes me really happy. I know that Python 2.2 therefor works well with the LFS but i have to use python 2.1.2 because 2.2 is not recommended for the use with Zope. Has somebody an idea? Best regards Ralph

Newbie: Usage of this(), self, context
by c.koll＠web.de 08 Feb '02

08 Feb '02

When I read the Zopebook it seemed to be quite understandable, but looking at some scripts now, I think I somehow mixed it up. What´s the difference between "this()", "self" and "context"? When do I use each one? regards Christian ________________________________________________________________ Keine verlorenen Lotto-Quittungen, keine vergessenen Gewinne mehr!
