Dynamically generating text graphics in Zope
by Anders Schneiderman 21 Aug '01

21 Aug '01

I'm trying to create a site for our intranet that will create text graphics that people can use to construct a web site ala Cooltext. For ex, I want to be able to let someone enter five different menu names, pick one of several color schemes/textures, and then spit back the graphics so they can copy them. Two questions: 1) Has anyone done this before, and if so how did they do it (and do you have code you'd be willing to share)? 2) If not, any suggestions on how to get started? Obviously, gimp on Windows is one solution, but I'm a bit daunted at the prospect of taking it on. Are there any apps designed for Windows that can be run dynamically w/o driving you crazy? My Zope site will be running on an NT box, so linux-only software isn't an option. Thanks, Anders

Access help
by Todd Loomis 21 Aug '01

21 Aug '01

Can anybody help, I'm trying to make a drop-down list of folders a user has access to add files to. However I only way I can get it to work is give each person access to contents permissions on all folders. So far it won't let the actually in the folder but it shows it to them. Here's my code how can I keep the folders the can't upload too for the list: <select name="folder"> <option value="" selected>Select from list</option> <dtml-with folders> <dtml-if expr="_.SecurityCheckPermission('Add Documents, Images, and Files', this())"> <dtml-in expr="objectValues('Folder')"> <option value="<dtml-var id>"><dtml-var title></option> </dtml-in> </select> </dtml-if> </dtml-with> Thanks, Todd

Re: Software Product: ImageTag_Hotfix

What __init__.py? If you're talking about in PIL? Version 1.1.2 of PIL comes with one in the PIL directory, so it should be fine. If you're talking about my hotfix, just tar -zxvf ImageTag_Hotfix-0.1.tgz in your Products directory. The key thing is making that symbolic link. I don't know why zope can't find PIL otherwise, since it works running python from the command line... > From: "Frank Schoefer" <fschoefer(a)gmx.de> > Date: Tue, 21 Aug 2001 16:29:41 +0200 > To: <marc(a)bowery.com> > Subject: Software Product: ImageTag_Hotfix > > Hi Marc, > > maybe a really stupid question regarding the ImageTag_Hotfix.

Postgresql DB Connector and string problem
by Russell Hires 21 Aug '01

21 Aug '01

Hello everyone.... I've got the PoPy db adapter connected to a postgresql database, and I'm following the example in the zope book with psql rather than gadfly. I'm able to create the tables and such, but when I submit a query on the table with the two strings, I get an error: Z SQL Method at /GradeBook/hire_employee Error, exceptions.NameError: string SQL used: Could not render the query template! Anyone know how I can correct this? Thanks! Russell

Zope vs. the Big Boys
by Robb Allen 21 Aug '01

21 Aug '01

Honestly, how does Zope compare to some of the big names such as BEA and WebSphere? My company is looking at spending a lot of money in the Application Server realm, and I wondered how Zope stacks up against them. We're two shakes of a pen away from purchasing something, and I'd like to at least come back with an open-source solution just so that we can compare something. Fire away. I need as much ammo as I can get (although, honestly, I'm leaning towards BEA) R

Virtual Host Monster troubles
by Lucas Hofman 21 Aug '01

21 Aug '01

I am trying to hide the CMF instance name when accessing the site through its 'official' URL, there allowing http://tanya.oslo.seres.pgs.com/research/ to appear as http://web.research.pgs.com. I had hoped VHM in the root of the zope installation, combined with some apache rewrite rules would do that. However, all URL's in the CMF site (news etc) look like http://web.research.pgs.com/research/xxxx. How come? Do I have to combine VHM with siteroot or siteaccess? the relevant part of my http.conf is NameVirtualHost tanya.oslo.seres.pgs.com <VirtualHost webdev.research.pgs.com> ServerName webdev.research.pgs.com DocumentRoot /home/httpd RewriteEngine On RewriteLog /etc/httpd/logs/rewrite.log RewriteLogLevel 1 RewriteRule ^/local/ - [L] RewriteRule ^/cgi-bin/ - [L] RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/webdev.research.pgs.com:80/resea… [P] </VirtualHost> The environment is Mandrake 7.0, Zope 2.3.2, CMF 1.0 Anybody any idea's? -- Regards, Lucas Hofman PGS Research work: +47 67514059 PO Box 354 fax: +47 67526640 N-1326 Lysaker, Norway home: +47 67581373

Re: [Zope] to convert images on the fly with zope

You could use PIL, if your TIFF image types are supported by PIL. Alternately, you could use tiffutils (this would be an external process called by Zope).

I did this by coding a python-fu plugin for the gimp that listened on a network socket and accepted connections from Zope. You could also use PIL and do it all in python.

Open Source -- Advantages
by Chris Keyes 21 Aug '01

21 Aug '01

Hi Robb I was reading an article in Linux User last night, an interview with the chairman of RedHat. He was talking about the problems of companies getting tied to a proprietry system and then building their business model around them... (See page 3, 'On Customer Control')... There were some arguments that seem obvious but aren't the ones that always spring to mind... http://www.linuxuser.co.uk/articles/issue12/lu12-Cover_feature-Bob_the_Build er.pdf 150k PDF... Well you can't expect everything from a publisher can you ;-) Not sure if that helps, but, its something that made sence to me :-) Good luck! Chris
