Hello, I am moving stuff from zope1 to zope2 and had this problem to: Inside a tree tag displaying an image with <dtml-var image_name> failed but with <dtml-var "image_name"> it works. I would like to know what is the normal behavious of the tree tag, shall I change my code to add the "" arround the image name?? I display a lot of small documents inside my tree , thoses document containing images (dot,etc..) so it's a lot of modification to do.

Accessing ZSQL results via classes
by Mike Mikkelsen 12 Oct '99

12 Oct '99

Hello all, I have been trying to assign the results of a ZSQL query to a class with no luck. I created a python class and defined it in the "Advanced" tab of the appropriate zSQL method, but I can't figure out how to access it. The manual says something about using an URL. Is there a way to access the class (and properties) directly from a dtml-var tag? Is this the only way to assign results to a class? Can it be done with a ZClass? Thanks. -- ========================================================================== Mike Mikkelsen mikk(a)microbsys.com Micro Business Systems http://www.microbsys.com Fresno Linux Users Group http://linux.fresno.ca.us Linux: The OS people choose without $200,000,000 of persuasion

Using ZODB outside of Zope
by Avus 12 Oct '99

12 Oct '99

Hi, he ZODB would be a possible choice for a desktop database. Could anyone point me to code examples (if there are any) to use ZODB and Catalog outside of Zope? Is there any effort underway to make C/C++ bindings (i.e. to allow C++ classes to be stored persistently in a transparent manner)?

Cache Technologies compared with Zope?

Caught this link through LinuxPR.com http://www.e-DBMS.com/cache/weblink/index.html I imagine a number of people here could wade through the PR and compare. I don't get the feeling that it is as sophisticated as Zope...

It sounds like you're basically trying to do a namespace lookup. <dtml-with "_[objA]"> should do what you want. Kevin

ANNOUNCEMENT: MySQLdb-0.1.1 released
by Andy Dustman 12 Oct '99

12 Oct '99

MySQLdb-0.1.1 is a bugfix release for MySQLdb, a thread-friendly interface to MySQL-3.22. Thanks to Stephen Gava and Mark Favas for pointing out a few problems. cursor.fetchmany() now works (one I never used) and some of the _mysql.conn methods probably would have dumped core if they were ever used (MySQLdb doesn't use them, but they are there for completeness), and didn't compile on some systems. Thilo Mezger pointed out the patched ZMySQLDA didn't return numbers on numeric columns; I had assumed that Zope did this conversion itself. Adding the minimal type converter dictionary from MySQLdb to the connect() call fixes this, and my understanding is that this means it is now really working 100%. As usual, it's available at http://starship.python.net/crew/adustman, and will soon be on www.zope.org as well. -- andy dustman | programmer/analyst | comstar.net, inc. telephone: 770.485.6025 / 706.549.7689 | icq: 32922760 | pgp: 0xc72f3f1d

Oh I see now. However big problem. With this scheme you can never have a string argument that begins with &

Heres my idea for this. Have a seperate ftp server running that uses different GET and PUT methods. These methods will work differently from just presenting the straight DTML. The GET method will do something like a rendering with the DTML encoded into comment tags. So <dtml-var standard_html_header> <ul> <dtml-in aList> <li><dtml-var sequence-item></li> </dtml-in> </ul> <dtml-var standard_html_footer> Would be rendered like  <html> <title>A big Title</title> <body>  <ul>  <li>Item1</li>  <li>Item2</li>   </body> </html>  Not exactly clean but it would mean a WYSIWYG editor could edit the whole page and as long as the comments were preserved then the everything would be fine. The PUT method would decode the above and turn it back into the orginal DTML. Changes inside iterations might have to be merged somewhat. Changes to server side includes could be propergated back to the included object as long as the user has permission to change it. Changes to variables like sequence-item can just be ignored. Changes to objects with which the user has no permission can similarly be ignored. Why go to all this trouble? a) It lets wysiwyg people make changes to DTML code hopefully without destroying it. b) It lets DTML people do a bit a visual design once in awhile. c) It lets beginers write content for a site that needs to have the standard footer and header on each page and still see what it looks like. d) It will allow Zope to do something no other server side scripting can do, successfully combine scripting and wysiwyg editing. e) It allows the use existing editors such as Homesite rather trying again with javascript or java or whatever. How can this be implemented? Having a quick look round the code, not easily. I think the recursive way DTML is parsed and rendered makes it hard to put extra steps between recursions. Does everyone think this a) Won't work very well b) Isn't worth it c) great idea but impossible to impliment. d) fantastic idea, I'll have it done tonight ....?
