Zope et navigator.platform
by Pascal Samuzeau 05 Feb '02

05 Feb '02

Hello, For some programs I need to know in which platform the client works. I did, until now, with the Javascript code : navigator.platform, to have the knowledge. I want to do the same under Zope, but without, if it's possible, to ask the client with Javascript. In Zope we have HTTP_USER_AGENT I've tried HTTP_UA_OS, but nothing return !! Anybody knows how to do it ? Sincerily PS -------------------------------------------------- Oreka ! Nous sommes l'internet moins cher ! Surfez 25% moins cher avec http://www.oreka.com

Xron Issue
by Tim Owen 05 Feb '02

05 Feb '02

I have two Xron issues that I am seeking assistance with: 1. I am getting the following error when the email_reminder_job gets triggered by the Xron scheduler. I also included a thread with Loren for additional context below the events.log contents as well. Anyone have ideas on what I am doing wrong? The event is scheduled for 5:30 AM EST, 10:30 AM GMT. It looks like it tried to run but got a bci.NotAvailable with a connection refused error. I have the admin folder secured but set the job up with manager, owner, and authenticated proxy rights. I also made the security rights not be acquired, but allowed all rights to the manager, owner, and authenticated users. After the job gets triggered and fails, it says it fails to disarm the event but the event disappears when I click on the schedule object in the ZMI after the job fails. 2. I recatalogged this morning at 5:56 AM which causes a conflict error and the dispatcher thread to die. Not sure what the conflict is unless it relates to the fact that I have another folder (http://www.iresolve.com:8080/iResolve-tim/admin/email_reminder_job) an XronDTMLMethod object with the same name. The second one is for testing purposes and is currently turned off. I renamed the second one and recatalogged again with the same error. I am using ZEO if that matters.

A copyied Xron DTML Method won't get put in the schedule, because cataloging only occurrs when the method is created or updated. You can get it in the schedule by editing it's trigger time in the XMI. You don't actually have to change it, just get Zope to think you changed it. 2002-02-03T16:16:33 PROBLEM(100) Products.Xron.Loggerr Trigger event: http://www.iresolve.com:8080/iResolve-tim/admin/email_reminder_job Trigger time: 2002/02/03 05:30:00 US/Eastern Failed to trigger event.

It indicates that the socket that Client.py uses to fire a scheduled method is not working. That would be a system-depended problem. I would try: 1) tracing with PDB, starting with the dispatcher and following it into client.py, to see if there's any obvious reason the connection is not working. You can uncomment relevant trace statements in Xron code. 2) making a little Client.py application to try to isolate that problem. There's a How-To on that subject somewhere on www.zope.org. That may be the cause of the errors that show later in the log. In any case, Xron won't work if Client.py doesn't work. Client.py is a standard part of Zope that Xron calls to simulate a client request for the Xron DTML Method. There used to be a problem using it with port designators in the URL, but that problem was fixed in an earlier version of Zope. Still, I haven't upgraded to 2.4.3, so I can't testify that Xron works there. You should copy these messages to the zope(a)zope.org list. Maybe somebody there has prior knowledge of the problem. But no HTML-encoded messages are allowed there. I'll leave that up to you. -- Loren -----Original Message----- From: Tim Owen [mailto:timowen@voyager.net] Sent: Monday, February 04, 2002 2:35 AM To: Loren Stafford Subject: Re: Xron Question I think this is either a permissions error or an error due to copying the XronDTMLMethod from my development server to the production server.

Re: [Zope] Newbies & variables

Alright. What does it return? Based upon this: >>> return special_formats['structured-text'](_[page_body]) It should return the result of calling whatever method is returned by getting the 'structured-text' element of the special_formats dictionary with page_body as the only argument. Whew! Why don't you just do this: myhome.html: <dtml-var name="standard_html_header"> <dtml-let page_body="'stuff.stx'"> <dtml-var name="dtml_wrapper"> </dtml-let> <dtml-var name="standard_html_footer"> dtml_wrapper: <dtml-if name="page_body"> <dtml-if expr="page_body[-4:] == '.stx'"> <dtml-var name="page_body" fmt="structured-text"> <dtml-else> <dtml-var name="page_body"> </dtml-if> <dtml-else> <dtml-var name="default_page"> </dtml-if> Am I making sense, or missing the point?

timeout
by Ulrich Wisser 05 Feb '02

05 Feb '02

Hi, one of my reports takes more than 5 minutes. This causes Zope to produce a timeout. Although it is no good idea to let the user wait that long, I would prefer to show a result anyway. How can I set the timeout? Thanks Ulrich

Strange behavior with FTP multi-homing.. not!
by JF 05 Feb '02

05 Feb '02

Hello, I have this problem with FTP that maybe someone can help me with.. I have a multi-homed Zope v2.5 site on Redhat v6.0, and I've made the root non-anonymous so customers that logged-in via FTP does not see others-account-website directory. Since FTP does not seems hooked-up to use VirtualHostMonster, everybody must pass by the root and then cd into-their-own-directory. When I FTP-in I have this weird behavior that I cannot explain myself.. the first time I go: ftp> cd /MySite I get: 550 No such directory. then the second time: ftp> cd /MySite 250 CWD command successful. then I go: ftp> ls 227 Entering Passive Mode (192,168,1,11,15,135) 550 Could not list directory. and the second time I pass the command it works!! ftp> ls 227 Entering Passive Mode (192,168,1,11,15,136) 150 Opening ASCII mode data connection for file list d--------- 1 Zope Zope 0 Feb 4 22:33 .. This baffles-me.. every second command passes but the first fails. Where is the state machine that makes a command not pass throu the same path two times in a row? Anybody would tell-me where to look for? The exact internal error seems to be 503 instead of the advertised 550 one. I'm using LoginManager for acl-users and it seems the first command does not hit my acl-users at all but the second does. oh well, if I define my ftp roles for every domain on the top folder, it seems to resolve the problem.. but then it gives-me a security tabs page of 1MBytes to manage all over the place.. so, I would prefer to use local roles. for sure.. Also in the same vein, while I'm at it.. I have another problem with my setup.. let say I have: / site1 www site2 www With my virtual hosts pointing to the www level. Customers can go like: www.site1.com/site2/www and they kind of "can" the other's customer's site!! How can I block "inheritance" in this case? Thanks very much for any comments, suggestions..

passing a dtml-var to another method: dtml-let has no effect?
by Panos Hilaris 04 Feb '02

04 Feb '02

Thank you all for your answers concerning ``forms: copying ...'' message ! Using the following in a document: <dtml-let x="'foo'"> <dtml-var x> </dtml-let> I get the expected "foo" in my document. However, if I try: <dtml-let x="'foo'"> <dtml-call sqlDistinct> </dtml-let> where sqlDistinct is a ZSQL Method having an argument with the name x, I get a KeyError. I have also tried to have the variable x defined from the start of my document, say with the value "bar". In this case, with the above portion of code, I get no error, but sqlDistinct uses the value "bar" for x and not "foo". In fact, I want to set the variable x many times in a document and call for each value of x the sqlDistinct query, so I need to change the x variable in my document. What should I do? With friendly salutations, Panos Hilaris

Zope as a CMS on top of Weblogic Portal Server
by Matt Gregory 04 Feb '02

04 Feb '02

I am looking at using Zope as the content management system on top of Weblogic's portal server. The benefits would be immense (Not having to teach JSP to content people alone would be heaven). In order to do this however I need to be able to import the Zope modules into python scripts I plan to execute from Jython. Is there a good reference to using Zope modules outside of Zope? I'm having a little trouble finding out what I need to import to get what class etc. (read: I'm pretty new to python as well). Thanks in advance -Matt

Automatic form generation
by Tom Nixon 04 Feb '02

04 Feb '02

Hi I have been experimenting with ZClasses, and I like the way you can add property sheets containing Strings, dates etc and have a data-input form automatically generated for each instance. However, it seems a little bit limited. For example I can't specify that I want a string, maximum of 50 chars, and a required field. Is there a product available for this sort of thing? Many thanks Tom

Generating emails with multiple attachments
by Maik Jablonski 04 Feb '02

04 Feb '02

hi to all, I've googled & egrouped, but could not find an answer... I want to send an email with attachments with the <dtml-sendmail><dtml-mime><dtml-boundary><dtml-var>-tags. It works well if I send an email with one or more "hardcoded" <dtml-boundary>-blocks. My problem is: I want to iterate over a folder and send all files as attachments. But mixing up <dtml-mime ...> <dtml-in ...> <dtml-boundary ...><dtml-var ...> </dtml-in ...> </dtml-mime ...> does not work ("unexpected tag error"), because <dtml-boundary> seems to be a blockContinous-Tag. Is there any reasonable way to do this with <dtml-in>, <dtml-mime> & <dtml-boundary>? Maybe with nested <dtml-mime>'s ? Thank you for an advice...
