[NEWBIE]: calculations
by Stephan Goeldi 30 Aug '01

What is the proper way to do simple calculations in Zope? e.g. if I have two variables: a and b I would like to let b = a*1,5 how can I do that with dtml? _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

Hello, here's a nice link about ZClass-properties-> http://www.zope.org/Members/lstaffor/zProperties and at the end there are more links or search on zope.org for zclass. Short description of the way: create product->create zclass-> create property-sheet->change manage_add method ->build form (with your html-select-box)->build add_method ->that's all With a little routine , you manage to follow this steps and build a basic class with no layout in 1 hour. Mit freundlichen Grüßen With kind regards Sven Hohage

Newbie question--external methods, DTML and DB connection persistence
by elian＠inbrief.net 30 Aug '01

30 Aug '01

Hello, I've been scouring all the documentation available (Zope Book, howtos, newsgroups, etc.) but still have not been able to establish: 1. Whether it is possible for external methods to send SQL queries to an RDBMS using database connections defined in Zope, so that the persistent database connections are used. Or, if this is not possible, how to do so with Python scripts. 2. How to return result rows from a SQL selection in an external method or Python script so that <dtml-in my_external_method> and <dtml-var column_name_from_result_set> tags work as well as when using ZSQL methods. I'm trying to do so because I'd like to move all logic out of DTML, using it just for templating (until ZPT is more mature and documented). I'd rather use external methods because Python scripts are just too limiting (e.g. no support for many of the modules I'd like to use). Can anybody please help me understand whether what I want to do is possible, and how to do it? ...Edmund.

zclass add method -- how to get at properties?
by Lee Harr 30 Aug '01

30 Aug '01

Setting up a form to add a ZClass instance TTW. One of the things on the add form should be a select box like in the propertysheets view of the ZClass. How do I get at those propertysheets values so that I can make the same sort of select box on my form? _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

Re: [ZPT] Is PageTemplates doing xhtml conversion? Should it?
by Geir Bækholt 29 Aug '01

29 Aug '01

Hello John, I have some related issues, which i am kind of puzzled by, as the original spec of ZPT was to go fro XHTML altogether IIRC: Is is not currently possible to create what are single attributes in "old-style-html" (selected, checked etc..) as correct XHTML (selected="selected") with tal:attributes.. if it also breaks onchange and its likes , i think we need to find a way to coerce it into using the XML-parser for XHTML, but still serve the pages with content-type text/html, to keep it working in most browsers. We have almost completely ditched DTML in favor of Page Templates, but as long as it is not possible to create proper XHTML with them , i consider them partially broken. hmm.. i actually think XHTML should be the default these days, with a "pre-html4.01-mode" for those going old-style.... :-) Wednesday, August 29, 2001, 15:28:47, you wrote: JM> I've been playing around with HTML tidy[1], using it to test some page JM> templates that are part of a skin for a CMF product I've written.

RE: [Zope] printable page
by Peter Borocz 29 Aug '01

29 Aug '01

I also saw that on Zope pages and then spent way too much time trying to find out how to do it from mailing lists etc. when I had the same epiphany that you did that simply "stripping" the navigation out of the standalone dtml-doc/methods would do it for my entire site. Thus, here's the link that I cobbled together that's in my standard html_footer (in this case, I use pp as the variable instead of printable as I thought that "might" be the standard): <a href="&dtml-URL0;?&dtml-QUERY_STRING;&pp=1"> <img src="zImages/printable" border="0" alt="printer-friendly version"> </a> I can't vouch for the "Zope" correctness of the URL variable though it seems to work for me. Cheers Peter Borocz -----Original Message----- From: Jan Ulrich Hasecke [mailto:janulrich.hasecke@web.de] Sent: Wednesday, August 29, 2001 7:03 AM To: zope(a)zope.org Subject: [Zope] printable page Hi, I saw that on zope.org you can get printable pages. How are they generated? I also want to integrate printable pages in my project. I want to do this by changing the standard_html_header. I would insert in standard_html_header something like this: <dtml-if expr="printable"> <html> <head> print-stylesheet <body> <dtml-else> <html> <head> screen-stylesheet <body> ...complex navigation </dtml-if> Similar in standard_html_footer. What would be the right if-construction and how can I set the condition "printable" dynamically from inside the given DTMLDocument. The Document should have a button or link which sets the condition printable while loading itself again.
