I think this should be fixed because the second solution adds unnecesary complexity to the tal-expression and I also think that it's an inconsistency that one works and the other don't.

python versions and zope
by Dennis Allison 27 Jun '03

27 Jun '03

PEP 6: "In general, only the N-1 release will be under active maintenance at any time." Python 2.3 is scheduled for early July (PEP 283i and dev-pyBthon mailings). Here's a tentative release schedule that follows the above guidelines: alpha 1 -- December 31, 2002 alpha 2 -- February 19, 2003 beta 1 -- April 25, 2003 beta 2 -- late May rc 1 -- late June final -- early July Unless I am mistaken, Zope 2.5.1, 2.6.0, 2.6.1 all *require* Python 2.1.3 and will not work with Python 2.2 and later. Do we have a problem?

Re: [Zope] Zope - enterprise

It is possible with ZEO. If you have one machine, try to implement squid as reverse caching proxy and think about ESI (www.esi.org) JL : Odesílatel: GIROTTO Diego (ESPIN) <diego.girotto(a)espin.it> Hy, is there anyone than can tell me any link or documentation about a generic Zope site (with or without CMF) performance with 1 milion of concurrenty users? In other ways, are Zope perfomance comparable with any other application server for enterprise portals solutions?

Returning an unrendered DTML Document object to a ZPT
by Dominic Hiles 27 Jun '03

27 Jun '03

Hi, I am passing an unrendered DTML document object to a Zope Page Template, as the first item of the list referenced by the 'args' key of the options namespace. I subsequently want to reference the attributes of this object. I have tried: <div tal:define="python:nocall(options['args'][0])"></div> but this gives a split error, the relevant portion of the traceback being: Module Products.PageTemplates.ZRPythonExpr, line 48, in __call__ __traceback_info__: nocall(options['args'][0]) Module Python expression "nocall(options['args'][0])", line 2, in f Module Products.PageTemplates.PythonExpr, line 81, in __call__ Module Products.PageTemplates.Expressions, line 158, in __init__ AttributeError: split Doing: <div tal:define="nocall: options/args"></div> correctly returns the 'args' list, with the object as the first item, but I can't seem to find the syntax to then reference this first item, without using a tal:repeat statement. Any help would be much appreciated. Dominic

Automated DHTML menu builder for Zope
by Jaroslav Lukesh 27 Jun '03

27 Jun '03

Hi all, today and for few another days Im too lazy (and busy) to publish them at zope.org. So if you want somebody, i could send you .zexp and .py. It needs transparent folder product installed (sorry) and has about 10k (zip). --------------------------------------------------------------------- Automated DHTML menu builder for Zope --------------------------------------------------------------------- This was done with big help of these softwares: * ZHierMenus python sctipts by Ioan (www.zope.org product, new javascripts need to pay) * HV Menu- by Ger Versluis (www.burmees.nl , www.dynamicdrive.com) Zope menu integration -------- 1. put following files to your virtual "/" folder or Zope root: File (mime text/javascript): hv_menu_var.js hv_menu_com.js DTML Method: hv_menu_tre.js 2. Copy file hv_menu.py to your Zope Extensions folder (at your local filesystem /var/zope/Extensions, not in zopedb) 3. Add External Method: id: hv_menu ModuleName: hv_menu FunctionName: hierMenus 4. Add _this_ file that you read just now to your virtual "/" folder or Zope root, call it as "hv_menu_GO" (DTML Method type) Using ------- * Write <dtml-var hv_menu_GO> at your DTML method - it will show you only the same and child levels * place DTML Document hv_menu_tre.js at your virtual server root - Write <dtml-var hv_menu_GO> at your DTML method - and this will show you full site structure at any page License ------- Please read license for Zhiermenu and hvmenu. But you could use it freely if you dont want to read licenses. History ------- 2003-06-30: Initial release !!! IMPORTANT !!! you need specify in hv_menu.py cell height and width, see source code. Further improvements: ------- Position is driven by function PosMenu(CntnrPntr,Tp,Lt) in menu_com.js so we can move menu across page when scrolling --------------------------------------------------------------------- Copyright 2003 Jaroslav Lukesh, lukesh`at`k-net.cz ---------------------------------------------------------------------

Rendering for WebDAV access???
by Johan Carlsson 27 Jun '03

27 Jun '03

Which method is called when a WebDAV URL is called? I thought it was either index_html/__call__ or document_src (when using the source port). Now I don't know anymore, or maybe I'm just experienceing a "bad" cache algoritm but I can't get anything but an empty string. I'm using WebDrive. Best Regards, Johan Carlsson

Epoz & relative links
by Sébastien Georget 27 Jun '03

27 Jun '03

Hi, I'm trying to edit a document with epoz which contains some internal links. If I create a relative link to anchor A and save the document, there are no problems. If I reload the document to make some modifications and save it again, my link becomes an absolute link (which is wrong since my edit_form is different from my view_form). This can be reproduced on the demo site. Is there a way to prevent epoz from converting relative uri ? Sébastien Georget http://purl.org/NET/Georget/Sebastien
