why two session identifiers?
by Mario Bianchi 06 Aug '02

06 Aug '02

Dear list, could anybody tell me why the Session product assigns a session id AND a session token to a session? I've noticed that expiration of the session data object causes (on a further request) the session id to change, while the token stays the same: any explications? Thanks, Mario. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx

I do not know why (I am not convinced by the explanation). However, I know that "RESPONSE.redirect" will not abort processing. It will traverse to the object, render it, and maybe, finally, redirect. Probably not, what you want. Are you sure you want to redirect to "self.login_form(REQUEST)"? The argument to "redirect" must be an (absolute) URL. > This gives me a "Resource not found" error. I expect, the redirect is executed but the return value of "self.login_form" is not really a valid URL. You get a "Not found". > You mentioned it would also be > possible to do it by raising an exception - but this is not totally clear to > me. raise 'Redirect',location "location" is the URL you want redirect to.

You use it the same way you do it elsewhere. But you have more methods available (also private ones). DocFinder/DocFinderEverywhere may help you to see what is available. Drawback: you may see also things you should not use because they are things from the old days and only retained for backward compatibility. Dieter

ZDataQueryKit Help!!
by Derek Basch 06 Aug '02

06 Aug '02

Hello, I posted the below question before but no one answered. So I guess I will now ask, does anyone have anyone have any experience with ZDataQueryKit? Can anyone give me a rundown of how to use the Z Report Tool? It looks like a great tool but I cant get it to work (see below). Thanks for the help, Derek Basch Hello, I am trying to learn how to use ZDataQueryKit w/ Firebird/Interbase and I keep getting a KeyError. I create a simple ZSQLMethod such as "SELECT * FROM T_CONTACTS" and name it "testmethod". I then create a Z Report Tool with the id and title of "report" and a Data Source of "testmethod". I press Add and Edit and I get: Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: PK_CON_ID I thought it might have something to do with the primary key column but I tried just selecting a non key column and it still fails. Rather than mucking around in code for hours, I thought I would ask if anyone has an idea what im doing wrong? Thanks in adavance, Derek T Basch __________________________________________________ Do You Yahoo!? Yahoo! Health - Feel better, live better http://health.yahoo.com

excellent note should be added to docs - how?
by A M Thomas 06 Aug '02

06 Aug '02

Hi there, I was reading through the digest of the zope list, and found Chris McDonough's explanation of the two session properties, browserID and sessionID, really great. Is there a procedure to get this chunk of information added to some kind of documentation tree? I looked around briefly on the Zope site and the ZDP site but didn't see anything. I'd love to just copy and paste this information into a Wiki or something, or create a new 'node' somewhere for it. I guess there's always Appendix B, but that's sooooo looong. - Am

Re: [Zope] Zope in intranet - the cool apps?
by Pawel Lewicki 06 Aug '02

06 Aug '02

Hallo, I want to add my $.02, too. Am I right that the main issue to build the complex portal (intranet) solution is a good conceptual model? There are so many aspects to integrate like content (portal objects, external files, etc.), newsboards or forums, user and permission management. And of course good indexes of all. Are there any attempts on that field? UML maybe? Pawel

Understanding acquisition in CMF/Plone
by Phil Glaser 06 Aug '02

06 Aug '02

Hi, I just got done reading about traversal in _The Zope Book_ (pp. 138-140) and am at a loss to explain how this is working in Plone. I have a Plone Site named "plonetest" and when I go to the user preferences page it brings up the following url: /proto/testplone/personalize_form So Zope is calling the personalize_form method in the context of the testplone object. But I can't figure out how personalize_form is being acquired. It would be simple if personalize_form were contained in testplone, but it's not: there are three versions of personalize_form lower down in the hierarchy: testplone/portal_skins/generic/personalize_form testplone/portal_skins/plone_forms/personalize_form testplone/portal_skins/zpt_generic/personalize_form >From what I read, I thought that the acquisition mechanism only works from lower to higher in the container hierarchy -- that if personalize_form is not contained in the testplone object, it just won't be found. But somehow, Zope is locating one of these methods and then running against the testplone object. What I read lead me to believe that in order to find an object more than one level below the highest container, you would have to include the path to the lower container (e.g., portal_skins/generic), or whatever, in the url. As a practical matter, I could figure out which form it's calling if I could find meaningful differences between the forms, by deduction, but that still would not answer my question: How did Zope know which personalize_form to call? Secondarily, for Plone, specifically, the member preferences page lets you decide which skin to use, but some of the names listed (e.g., "plone default", "Plone XP") do not appear as distinct folders in the portal_skins container. Am I missing something? Thanks! Philip Glaser Principal and Software Architect Sustainable Software Solutions, LLC StillSmallVoice(a)DirectvInternet.com www.sustainsoft.com 973-951-9522

Reading parameter from DTML
by HT 06 Aug '02

06 Aug '02

Hi, I need help on why my dynamic page reading doesns't work. As an example below, I have a DTML-Method called dtml_action. this dtml_action will read the parameter from page (from the same directory) that invoked it. dtml_action document: -------------------------------------------------- <dtml-var standard_html_header> <dtml-var page> <dtml-var standard_html_footer> ------------------------------------------------- As an example, my index_html need to diplay history_html document by using dtml_action. index_html document: ---------------------------------------------------------------------------- <dtml-if page> <dtml-var dtml_action?page=history_html> </dtml-if> ------------------------------------------------------------------------- The code inside index_html definitely doesn't work because there isn't such variable like 'dtml_action?page=history_html' But I just don't know the syntax. Can anyone help?

CallProfiler and structured_text
by Peter Bengtsson 06 Aug '02

I installed CallProfiler and then structured_text from PythonScripts.standard stopped working. Removing the CallProfilder fixed things.
