Extracting query string parameters from a URL
by Asad Habib 08 Mar '03

08 Mar '03

Hello. Does anyone know how to extract query string parameters from a URL? I am trying to limit access of a DTML page to users who have a particular user name and id. Users who try to access this page have to enter something of the sort: http://localhost:8080/somepage.html?user_name=someuser+userid=djje Is there someway to access the values associated with username and userid in the URL above? Any help would be greatly appreciated. Thanks. -Asad __________________________________________________ Do you Yahoo!? Yahoo! Tax Center - forms, calculators, tips, more http://taxes.yahoo.com/

Updating Database Records
by Asad Habib 08 Mar '03

08 Mar '03

Hello. Does anyone know whether a Z SQL method has the permission to make modifications to already existing data by using the SQL update command. I am calling a Z SQL method that attempts to do this from a DTML method that has a proxy role of 'manager'. However, when this Z SQL method is called, Zope flags me with an error saying that I am "Unauthorized". Now, when I call another Z SQL method from this same DTML method that inserts records into the same database, everything works fine. Is there some restriction against modifying database records in Zope? Any help would be greatly appreciated. Thanks. -Asad __________________________________________________ Do you Yahoo!? Yahoo!

Virtual Host Newbie
by Zoper 07 Mar '03

07 Mar '03

Hi All. I started playing with VHM, but I have some problem. This is my apache configuration. NameVirtualHost 127.0.0.1:80 <VirtualHost 127.0.0.1> ServerName www1.antonella.it RewriteEngine on RewriteRule ^/(.*) http://127.0.0.1:8080/VirtualHostBase/http/www1.antonella.it:80/www1/Virtual HostRoot/$1 [P] </VirtualHost> I have a folder www1 on Zope. When I send this request http://www1.antonella.it I obtain the index_html object present in the www1 folder <dtml-var standard_html_header>  <p> l'home page </p> <p><a href="ciao">Ciao a tutti<a></p> <dtml-var standard_html_footer> Ok, but when I click on ciao (it exist) I obtain nothing more then a refresh of index_html. Why? Best regards. Gius.

Logging a User Out
by Edward Pollard 07 Mar '03

07 Mar '03

I'm up to my elbows in ripping apart the ZMI to find the code, and its another basic idea, so I thought I'd throw it out to the list. How can I programatically (Python/Page Templates) clear the login information from the browser? That is - log someone out. Setting up the permisions with the LDAP users was straightforward, but at the moment all I can do is detect the lack of permissions and say "Access Unauthorized". The only way to switch users is to open a new browser. This, of course, is immature and - if you'll excuse the colloquialism - sucks hard. So I'd like to offer a button that says "Log me out". Amusingly, the Security chapter of The Zope Book does not seem to cover this. Maybe it shouldn't and I'm just easily amused. Thanks, Ed

RE: [Zope] Single authentication for several servers
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 07 Mar '03

I've faced a similar situation (Though not with Zope at all actually) ... The way I prefered was to set the cookies for both domains in one pass, by using cascading scripts on each server, so that when you log in to one, it sets cookies for itself, and then transparently calls a script on the other site asking IT to set cookies for itself. This of course depends on both sites using the same cookies, which may or may not be the case depending on exactly how you authenticate. But it's an option, Cheers, J.F. -----Original Message----- From: Thierry FLORAC [mailto:thierry.florac@onf.fr] Sent: Friday, March 07, 2003 12:57 PM To: zope(a)zope.org Subject: [Zope] Single authentication for several servers Hi, I'd like to setup this environment : - I have a first site, handled by Zope, behind an Apache server and rewrite rules. Authentication on this server is done throught an LDAP server with LDAPUserFolder. - I have a second site on a different server, handled by Apache+PHP. Authentication on this server is done throught the same LDAP server, so with the same login/password, throught mod_ldap. My problem is that when I switch from the first server to the second, I'd like to avoid a second authentication. So my idea was to access to server2 throught "http://www.site1.com/site2", with Apache handling a new rewrite rule in proxy mode. Do you think that it should work (I can't test easilly before asking you !!) ?? Of course : - I don't have any SSO solution ; - I can't rebuild my PHP application with Zope before several months :-(( (but I can update scripts to take the new access path into account). Thanks for any help or advise.

COMObject product question
by Micheál Healy 07 Mar '03

07 Mar '03

Hi, Has anybody used the COMObject product package much? I have been trying on and off to put data into an existing Excel template and display the result within the browser. I can do it using an external method to populate the spreadsheet and save it, then using the LocalFS product to retrieve the file and return it to the browser. This is all fine, but I was wondering if there wasn't a better way. Does anyone know if it's possible to return the Excel file to Zope as a COM object (without having to save the file to the local filesystem of the server) and just sent it to the browser as binary content, setting the content type. Does the COMObject product work like this? Thanks, Micheál Micheál Healy Engitech Ltd. 01 6204 516

The problem is created by setting the "save_interval" greater than 4. After changing the setting the error message went away.
