What's not clear to me is how these Python objects live and >die, and when. I think you leave out one critical thing. The business objects should be callable by all potential users of your system. the idea is the abstract out the business logic so that both your internal employees, intranet users, internet users and maybe even VPN nodes all use the same core business logic layer. Other then perhaps CORBA based middle layers I don't know of any way to achieve this ideal though. It baffles me that this simple and obvious need is not being filled with today's technology. Especially considering the myriad of languages that each part of the enterprise is using. Javascript on the browser ==> Python/PERL on the web server ==> C/C++/Java business layer ==> PL/SQL or other proprietary language on the database. Of course if SUN cared enough to make the applet a viable technology all of our problems would be solved. We could use Java on every layer (including the database server if you are using oracle). Too bad though I have yet to see a decent data entry tool written as a java applet. ---------------------------------------------- Tim Uckun Mobile Intelligence Unit. ---------------------------------------------- "There are some who call me TIM?" ----------------------------------------------

Domain-restriced anon access AND user restricted directories.
by Guy Davis 17 Feb '00

17 Feb '00

I am trying to setup access to my zope server so there is anonymous (but domain-restricted) access to folders except for those which have user list in acl_users. I have tried the followng setting this up so that AnonDomain is a role and AnonDomainUser is a user in the root acl_users with role=AnonDomain and an empty password. I then turn off all Anonymous role permissions and move them to the AnonDomain role on the root folder security tab. Then in /Projects/TestProject, I have a whole set of users. There is no anonymous access to TestProject. When someone from the right domain brings up the root folder, they match to AnonDomainUser but when they try to bring up TestProject, their username and password are consistently rejected (even though they are correct). (Note: correct users are part of the Developer role which does have the correct permissions.) If I then go back to the security panel of the root folder and give the Anonymous role just the capability to view, they can then login properly and access TestProject, but then I have lost the domain filtering on anonymous viewers. Has anyone out there got both anonymous domain restricted access and user authentication on certain directories? Does anyone have any idea why this isn't working for me? Thanks. -- Guy Davis mailto:davis@arc.ab.ca (403) 210-5334 Alberta Research Council

Rename the STX_Document to 'index_stx', and then try various hacks at to render it within a "generic" 'index_html' DTML Method: - '<dtml-var index_stx>' doesn't render correctly - Nor does '<dtml-var "_.render( index_stx )"> - '<dtml-call "RESPONSE.redirect( 'index_stx' )">' does, but it munges the URL as visible to the user. 2. Make the STX_Document class "renderable": - Add a new ZClass, RSTX_Document to the product, subclassing from the Renderable base class in Lalo's "Renderable product":http://www.zope.org/Members/lalo/RenderableZClass and from CatalogAware (in that order). - Copy the property sheets and methods from STX Document, and duplicate the Views tab. - Copy and paste the 'index_html' method and rename the copy to 'render'. - Add an RSTX_Document named 'index_html' to a folder. View the folder. **THIS WORKS!** I don't know whether to introduce the dependency on Lalo's product, but this workaround should solve your problem. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Altering values from HTML forms before SQL insert
by Neil Bartlett 17 Feb '00

17 Feb '00

I have a HTML form that returns a value that I need to alter before I pass it to a SQLMethod. To do this I created I've assumed I should use either dtml-with or dtml-let to create a new variable with my desired value and then call the SQL MEthod within the dtml-with. Some sample code is as follows. SQLMethod: ID:odbcInsertTalk arguments: LocationAndTime Query: insert into talk (LocationAndTime) values ( <dtml-sqlvar LocationAndTime type=string> ) DTML Document: <dtml-var standard_html_header> <dtml-with "_.namespace(LocationAndTime=Location+'--now')"> <dtml-comment> <dtml-call odbcInsertTalk> </dtml-comment> <ul> <li>Location: [<dtml-var LocationAndTime>] </ul> </dtml-with> <dtml-var standard_html_footer> I get my desired values for LocationAndTime for the code as shown however, if I uncomment <dtml-call odbcInsertTalk> then I get a complaint Error Type: Bad Request Error Value: ['LocationAndTime'] odbcInsertTalk works fine when I test directly from the SQLMethod manager page. I t also works if I remove the <dtml-with> and change the HTML form to send the exact name (of course this does not have the value I want but it does get correctly added to the DB) I'm using ODBC DA version ZODBCDA-3.1.0b2-win32-x86.tgz. Zope version: Zope 2.1.4 (binary release, python 1.5.2, win32-x86) Python version: 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)] System Platform: win32 Process ID: 217 (264) Running for: 3 hours 24 min 35 sec Any help would be very apprecitated.

Re: [Zope] RAM session management

Scalability is very important to me. I have to keep in mind eventual load balancing: using more than one Zope webserver. So the session data must be accessible from many Zope servers. This makes the current FSSession and Gadfly-based SQLSession unsuitable. Current FSSession and SQLSession are all designed for single-server configuration. I could use SQLSession with another database, (including an independent Gadfly), with some optimization like keeping things in RAM during a transaction. Cron job or explicit cleaning will be needed to clean up the session_data table, if computer crashes. For the immediate short term, I guess I'll use this approach. RAM session clears the session_data automatically when the computer crashes. :) Performance is faster, reliability is about the same as an SQLSession. It's easy to scale up. When hackers attack, it's probably better to have junk filling up my RAM than junk filling up my disk/database. One drawback is it gets expensive when you have too many users... but that's probably OK.

TinyTable & standard_error_message
by Roman V. Isaev 17 Feb '00

17 Feb '00

I can't use TinyTable in standard_error_message. I have a tiny table "mainmenu" with two columns, mm_ref and mm_text. When I do: <dtml-in mainmenu> <a href="<dtml-var mm_ref>"><dtml-var mm_text></a><br><br> </dtml-in> in standard_html_footer, all normal pages are ok -- it does generate menu. But when I try to request non-existant document, zope immediately starts to print built-in error message instead of my standard_error_message content! If I remove these lines from standard_html_footer, everything is ok again. Why this happens? How to use TinyTable in standard_error_message? -- Roman V. Isaev http://www.tcu.ru System Administrator P.S. RedHat 6.1, Zope 2.1.2 (installed from rpms), TinyTable beta 2.

first time - superuser authentication
by darcy w. christ 17 Feb '00

17 Feb '00

hi zopers!, i'm trying to setup zope on redhat 6.1. i've installed Zope-2.1.2-3.rpm and Zope-zserver-2.1.2-3.rpm. i ran into some trouble logging on as the superuser. i found some archives from this list telling me to simplify the /var/zope/access file with superuser:123. i did that and restarted the server (using /etc/rc.d/init.d/zope restart). Anyway, i still cannot log on. So now i'm wondering whether there are any other considerations i need to be away of. i did find some information about some servers cutting out the http authenication headers, but i'm assuming that since i am using Zope-zserver, that won't happen. Could someone give me some advice on this matter. i would really like to check out Zope - it looks awesome! Thanks for any help that anyone can offer me. -- ~darcy w. christ Elegant Communications Inc. 416.362.9772 x222 | 416.362.8324 fax

Hi all, As absolute_url, is there a relative_url? I made a grep on the source and found zero. But I found some posts with code using relative_url. On my dtml I receive a KeyError. Can anyone give me the Zen :-) Best Regards, Júlio Silva ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
