Since Transience is an external product, I'd have to extend it externally. Hmm, I wish that was documented in "The Zope Book" :-/ It's also be somewhat "challenging" to implement a keys method--the only thing I can think of is to extend the notify on add or delete methods to do housekeeping on the keys before actually doing the user defined functions for notify on add or delete. Sounds like a lot of work in comparison to just adding an already existing keys method to the API. I really don't want to have to manage a patch unless it's added to Zope :-/ Best Regards, -jj -- Hacker is to software engineer as Climbing Mt. Everest is to building a Denny's there.

Can I choose my python installation?
by Micheál Healy 06 Mar '03

06 Mar '03

Hi, If I have python installed on my PC, can I use that installation instead of that installed with Zope? The reason is that I am having trouble installing the win32 library for python on the Zope python instance. It fails to load pywise32.dll(?). I'm using a Win98 machine. TIA, Micheál Micheál Healy Engitech Ltd. 01 6204 516

Html2pdf problems
by Mehmet Yousouf 06 Mar '03

06 Mar '03

Hello all, I'm trying to generate a page to print and felt the best way is to convert it to pdf format. The information is on a database (mysql) and when I use <dtml-in printinfo> in the page, it renders the dtml page ok and by putting /html2pdf at the end of the url, it creates the pdf file. However, if the dtml-in command is passed a variable (<dtml-in "printinfo(nameid="SESSION['nameid']">), the dtml form renders fine but the pdf file will not be generated by it. I have tried sorting after the dtml-in command but the same story, even doing a <dtml-var "SESSION[nameid']"> while zope renders it, will not get converted to pdf..... if I save the file and use hmtldoc -f nameid.pdf nameid.html --webpage, it works. Any suggestions how I can resolve this problem? Regards, Mehmet

odbc da for zope on linux
by andy 06 Mar '03

06 Mar '03

Hi, Am I right in syaing that there is no such DA for zope running on linux? I can find the DA for the win platform, but can't find an equivalent for Linux..... I need to access information in an Access copied on a Linux server (where zope will also be running). All the clients connected to the server are Win98, so can't run Zope as a service anywhere else. Not sure if there's a problem with accessing data from this db if it's on the Linux server - if there is then I'll just point the DB request to one of the network machines. But first I need to get an adapter that works, and so far I can't see one. Andy

XML
by D. Rick Anderson 06 Mar '03

06 Mar '03

What is the best way to parse XML with Zope? I've been digging all over the site, and the docs there keep talking about adding an XML Document, but that option doesn't exist on my Zope server (2.6.0 on RH 8.0) and I can't find anything indicating that there needs to be a product installed. Simply put, I want to be able to grab an XML document with webclient() and be able to parse the contents of the XML using DTML. TIA Rick

Calling DTML document from a string/query
by Jan Maška 06 Mar '03

06 Mar '03

Hi all, Though it may seem as a stupid question, it's rather important (at least for me).. How to create a DTML document pointer (<dtml-var required_document>) from a string? Let's see this example: www.mydomain.com/somepath/index?read=20030220 What I need is that the index at somepath opens another document called '20030220' and prints it's contents, like in this case: ==index== <dtml-var standard_html_header> <dtml-var "20030220"> <dtml-var standard_html_footer> ===end=== only I want to be able to define this dynamically based on the user queries. If you can give any hints, it would really be helpful. -Mac =============================== Jan Maska, web developer Systinet, Prague(CZ) jan.maska(a)systinet.com tel.:(+420)608453492 visit http://www.systinet.com ===============================

Read conflicts
by Jakub Wisniowski 06 Mar '03

06 Mar '03

Hi all I've got some pages in my Zope application that display results of SQL query (results returned by Z-SQL Method) and check for existence of some data in SESSION object. There is nothing more on the pages but one thing - pages are refreshed every 30 seconds. I also have some users (really not many) that constantly monitor these pages. The last thing I've got is some error messages. The error message that displays on page looks like: An error was encountered while publishing this resource. ZODB.POSException.ConflictError Sorry, a site error occurred. Traceback (innermost last): ° Module ZPublisher.Publish, line 150, in publish_module ° Module ZPublisher.Publish, line 127, in publish ° Module ZPublisher.Publish, line 127, in publish ° Module ZPublisher.Publish, line 127, in publish ° Module ZPublisher.Publish, line 122, in publish ° Module Zope.App.startup, line 142, in zpublisher_exception_hook ° Module ZPublisher.Publish, line 102, in publish ° Module Zope.App.startup, line 200, in commit ° Module ZODB.Transaction, line 235, in commit ° Module ZODB.Transaction, line 349, in _commit_objects ° Module ZODB.Connection, line 391, in commit ° __traceback_info__: (('BTrees.OOBTree', 'OOBTree'), '\x00\x00\x00\x00\x00\x00\x01\xcd', '') ° Module Products.TemporaryFolder.TemporaryStorage, line 134, in store ConflictError: database conflict error (oid 00000000000001cd, serial was 034b62206010624c, now 034b621e679953b3) This error usually disappears after refreshing the page (but confuses the users). Some of error messages that are logged in my "stupid" log: 2003-03-06T09:50:36 INFO(0) ZODB conflict error at /ctt/cmp/info/yesterday/midday/index_html (138 conflicts since startup at 2003-03-05T16:20:08) ------ 2003-03-06T09:52:29 INFO(0) ZODB conflict error at /ctt/firm/props (139 conflicts since startup at 2003-03-05T16:20:08) ------ 2003-03-06T09:52:39 INFO(0) ZODB conflict error at /ctt/firm/props (140 conflicts since startup at 2003-03-05T16:20:08) ------ 2003-03-06T09:52:49 INFO(0) ZODB conflict error at /ctt/firm/index_html (141 conflicts since startup at 2003-03-05T16:20:08) ------ 2003-03-06T09:53:08 INFO(0) ZODB conflict error at /ctt/cmp/info/yesterday/index_html (142 conflicts since startup at 2003-03-05T16:20:08) I have searched mailing lists, but I didn't find the answer for the question - what's going on? and what interests me most: what to do with this? I've found some sugestions that such errors called read conflicts may be caused by using the session. Is that true? Why the session? I don't think that I can stop using session object. Any more suggestions? Any solutions? There must be any simple solution - my app has only few users! Thanks -- Jakub Wisniowski

Proxies for Z SQL Methods
by Roger Fisher 06 Mar '03

06 Mar '03

I have a Z SQL method that wants to use document_src. Unlike a DTML Method, there is no "proxy" tab for me to set the Manager permission. As a workaround, I execute the document_src in the calling DTML method and pass the result as a parameter to the Z SQL method.... but I wonder if there is a more elegant solution?

Some VHM questions
by AM 06 Mar '03

06 Mar '03

I have a zope site running behind apache 2.0. The zope istnace has a VHM in there that maps to a domain. I had a few questions about the VHM workings. In my site the primary structure is as such: / /nbs_online/ ( maps to nbs.neuro-bs.com ) /nbs_online/information /nbs_online/secure ( maps to secure.neuro-bs.com ) /test (doesnt map to anything ) The required rewrite rules are in the httpd.conf and ssl.conf The problem is I can access /test or for that matter any other URL outside nbs_online via the url nbs.neuro-bs.com/test or whatever the folder name is. The rewrite rules are given below. My question is why?? Secondly the rewrite rules in my virtualhost nbs.neuro-bs.com (httpd.conf) RewriteRule ^/secure/(.*) https://secure.neuro-bs.com/$1 [R] RewriteRule ^/(.*) http://192.168.10.172:8080/VirtualHostBase/http/nbs.neuro-bs.com:80/nbs_onl… [L,P] and the rewrite rules in my ssl.conf for virtualhost (secure.neuro-bs.com) RewriteRule ^/(.*) http://192.168.10.172:8080/VirtualHostBase/https/secure.neuro-bs.com:443/nb… [L,P] However is you look at the folder structure above, can anybody explain why I can access the folder information via: https://secure.neuro-bs.com/information which should be mapping to https://nbs.neuro-bs.com/secure/information and thus raising a 404??
