Hi How could I know if Zope was started using the -D flag? I would like to use that as a default value for my own debugging flags Gabriel Genellina Softlab SRL

finding the owner of an object
by Steven Turoff 26 Jan '02

26 Jan '02

Greetings, I need to find out if a user owns a particular object. More specifically, I would like to present some HTML if the user is the owner of the current page. Something like: <dtml-call "REQUEST.set('userName',_.SecurityGetUser().getUserName())"> <dtml-with owner_info mapping> <dtml-if "userName == id"> Write some html </dtml-if> </dtml-with> This works fine if the user is a manager, however if not, I get: Site Error An error was encountered while publishing this resource. Unauthorized You are not authorized to access owner_info. Is there a security setting that I need to change? Or is there a better way of doing this? Thanks, Steve

Problem with VirtualHostMonster response
by Ewoud de Boer 26 Jan '02

26 Jan '02

I have a strange problem. To access Zope I use an apache rewrite rule: <VirtualHost 192.168.1.2:80> DocumentRoot /var/www/hosts/www.dbde.nl/ ServerName www.dbde.nl RewriteEngine On ReWriteRule ^/zope(.*) http://www.dbde.nl:8080/VirtualHostBase/http/www.dbde.nl:80/dbde/VirtualHost Root/$1 </VirtualHost> This process works fine. I have a VirtualHostMonster in my Zope root, and the folder dbde is present. When I type the URL www.dbde.nl/zope i get directed to the right directory, but not all the content can be displayed and the URL is not rewritten in the webpage that is the result. It is: http://www.dbde.nl:8080/VirtualHostBase/http/www.dbde.nl:80/dbde/VirtualHost Root/. Apparantly Zope can interpret the VirtualHostRoot but not the other part. You can try it for yourself on the link above. I already tried a complete new install of Zope, but to no avail. What is the cause of this and how can it be solved? Regards, Ewoud de Boer

mysql database difficulties: creating tables with zope
by rhood 26 Jan '02

26 Jan '02

I'm just learning to use Zope. I've set it up, created some working sites, and love it. Now I'mt rying to make it work with a new mysql database (so my problem could very well be with the configuration of the database!) I would appreciate any help! I was working through an example and tried to create a table (using the "test" screen in zope): CREATE TABLE users ( user_id char(25) NOT NULL, cpasswd char(25) NOT NULL, Id int(11) DEFAULT '0' NOT NULL auto_increment, PRIMARY KEY (user_id), KEY Id (Id) ); and get the following error: Error Type: sql.error Error Value: ('42000', 1064, "[TCX][MyODBC]You have an error in your SQL syntax near ';\n' at line 7") I seem to get this error (esp the part about ;\n ) when I try to create a table. I can view tables, and otherwise test the database. thanks for any help!

Photo Product: Can't convert images.
by Mark Simpson 26 Jan '02

26 Jan '02

Hi, I'm using the Photo Folder product, and I'm trying to convert a number of jpg's by using the "Python Script" shown in the README.txt for the product: """Convert all Image objects in folder to Photo objects""" for image in context.objectValues(['Image']): context.manage_delObjects([image.getId(),], REQUEST=context.REQUEST) context.manage_addProduct['Photo'].manage_addPhoto(image.getId(), image.title, image.data, REQUEST=context.REQUEST) I get the following error when calling the Image2Photo script on the folder: Error Type: AttributeError Error Value: 'string' object has no attribute 'read'  And line 654 in Photo.py is photo._data = file.read() in manage_addPhoto python method. I'm using ExtFile and the ImageMagick engine. Can anyone see what I'm doing wrong, or what I need to fix? Thanks Regards Mark Simpson

FYI: KDE CVS has WebDAV support now!
by Joachim Werner 26 Jan '02

26 Jan '02

Hi! Thanks to Hamish Rodda, KDE 3 will finally support WebDAV! What does that mean for Zope users? In KDE 3, You'll basically have a simple Zope IDE and Content Management tools for free: You can log into your Zope server via WebDAV in Konqueror, and use any KDE-aware editor to create, edit, and upload code and content! This is even better than using Zope on the Windows plattform, as WebDAV/Webfolders are not integrated the same way WebDAV will be in KDE (i.e. seamless open and save from ANY KDE program). Cheers Joachim

Open the "index.htm" file in a folder
by Allen May 26 Jan '02

26 Jan '02

I am trying to setup navigation on my site. I want to open a default page when you go into a subfolder (like a default or index.htm). When I try this, it just shows the DocRoot file. Example: root index.htm | | |------------- | | | SubFolder1 | index.htm | | |------------- | SubFolder2 index.htm |------------- | SubSubFolder1 index.htm When I go to SubFolder1 or SubSubFolder1 I go back to the root index.htm. Why is it doing this rather than opening the index.htm? Thanks -Allen

Re: [Zope] Adding a Factory results in a new ZCatalog index type
by Maik Jablonski 26 Jan '02

26 Jan '02

dear lennart, dear dieter, thank you for help, but i think there is some kind of misunderstanding... maybe my english is not so well... sorry for that. in short-terms: when i add a simple new product with a "add list name" like TEST (as described in the Zope Book), then 'TEST' will be displayed in the list of INDEX-Types in a ZCatalog ('TextIndex', 'KeyWordIndex','PathIndex','FieldIndex' and 'TEST'!!!!!!!!!). that's what i don't want. in long-terms: what do i do (i would be glad if someone could test this on his own machine and report what happens, would take only a minute..:-)) (there's no use in this product, it's only to reproduce the effect very quick...;-)): 1. Take a fresh install of Zope 2.4.3 or 2.5.0b4 (you can surely use your configured install, this is only to avoid mistakes caused by other products or so.) 2. Go to the Product-Management and add a new Product (call it TheTest or something) 3. Enter the new product 'TheTest' 4. Add a DTML-Method with id = hello (don't change the source) in the product 'TheTest' 5. Add a Zope Factory with id = TheFactory, Add list name = TEST, Initial method = hello 6. Now create a ZCatalog somewhere in your Root-Folder or elsewhere or enter an existing ZCatalog 7. Enter the ZCatalog and CLICK ON THE INDEXES-Tab (!!!!!!!!!!!!) 8. Now pull down the "Select type to add..."-Menu. In my Menu are now: FieldIndex KeywordIndex PathIndex TEST <-- That's what i don't want here TextIndex My question is: what do i have to do, that this does not happen, because it's a little bit confusing, because TEST is not an Indexer at all... I've tested this on 2.4.3 and 2.5.0b4... fresh installs, same results. thank you for your further help in advance. greetings, maik jablonski >From: "Maik Jablonski" <maik.jablonski(a)uni-bielefeld.de> > >>Adding the new product metatype to the "Select type to add..." in the >>Management Interface is that what I want and what i get!!! but I DON'T >> >want an > >>entry in the "Add list name" in a ZCATALOG's INDEX-Tab.

RE: [Zope] Folder with one million Documents?
by sean.upton＠uniontrib.com 26 Jan '02

This will be taxing on Zope, so you need to be willing to be patient enough to optimize your application a bit. BTreeFolder works well for this, provided you are willing to consider bypassing use of the ObjectManager APIs and read/write to BTreeFolder._tree directly or use BTreeFolder._setOb() and BTreeFolder._getOb() instead of ObjectManager._getObject()... You also will REALLY need some nice hardware. I would suggest the fastest box you can get with LOTS of RAM. I would look at something along the lines of a Dual Athlon 2000+ (P-rated, not MHz) box with 3-4 GB RAM, and a striped RAID volume of fast disks. I have a BTreeFolder-derived folder and have populated it with about a third-of-a-million Cataloged objects, with each object using an underlying relational datastore, and about 8 Cataloged indexes, mostly field indexes index the result of a relational query; bulk adding these objects from a RDB datasource with cataloging takes about 2-3 hours on a P4 1.4GHz, and right now with my application, the Catalog is broken until a bulk-reindex on the advanced Tab of the Catalog - another 2 hours. I don't think BTreeFolder is a problem, but I would suspect that reindexing a Catalog with 3 million documents with full-text search setups would take you over 10-15 hours on a fast computer, longer if there is a complex amount of filtering document formats involved.

Hi! I am developing a simple DMS. Up to now I use a python product with a BTreeFolder which contains all the documents. Every document gets an ID with DateTime().millis(). There will be up to 50 users working at the same time. And in the end I will have up to 3 million documents. Is there a better class than BTreeFolder for such mass storage?
