SQL query results as <dtml> values ?
by Richard Smith 30 May '00

30 May '00

Maybe my question was too dense. I will try again. lets say I do this in a ZSQL method SELECT * FROM foo; of course I get a table of results. Now can I some how run another query base on the results, like to do an UPDATE and have the <dtml-sqlvar type=blah> use the values from the table ? Please, I just need a little help here. Thanks Richard

file import
by Rick Pasotto 30 May '00

30 May '00

Newbie question: what exactly does file importing do? I created a new directory then a new standard_html_header. I then imported a template file from a static web site, deleted the footer lines, and saved. Then I created a new standard_html_footer file and tried to import the same template file. It's still trying to connect to the zope server! Did the first import create some kind of lock? Second (unrelated) question: When I create and then select a new version I get a screen that says the version is not active and to press the button to activate it. Pressing the button returns me to the same screen saying that no version is active. What have I missed in using versions? -- It will be of little avail to the people that laws are made by men of their own choice if the laws be so voluminous that they cannot be understood... or undergo such incessant changes that no man who knows what the law is today can guess what it will be like tomorrow." -- James Madison Rick Pasotto email: rickp(a)vnet.net

Re: [Zope] ZCatalog previous and next items in list

Hi Chris, > I am using a <dtml-in> to walk through a catalog and display the results > ... > If the user click on Item 2, I want to pass the id of Item 1 and Item 3 > to the next page. "dtml-in" iterates over a sequence. You can directly access elements of the sequence. This looks like: <dtml-let S=sequence> <dtml-in S> <dtml-var "S[_['sequence-index']-1].data_record_id_"> </dtml-in> </dtml-let> Of cause, you must handle boundary problems, maybe with <dtml-try> or <dtml-if>.

You can access it via "AUTHENTICATED_USER". If your user allows cookies, you can save the username in a cookie. Otherwise, you should look at a session product (FSSession/SQLSession). Dieter

"DTMLMethod" and "DTMLDocument" have a method "document_src" that return their source (as text/plain). You can let your browser save this as a local file, edit it and later upload it again. Attached is a patch that exposes this method as a tab.

Re: [Zope] Working with ZopeTime
by Dieter Maurer 30 May '00

30 May '00

Hi Tom, > But not with: > <dtml-if "date1 == '<dtml-var ZopeTime fmt=Day>'"> > (and yes, the day I'm doing it on is Tuesday). Usually, DTML-tags cannot be nested. Exceptions: tags in compound tags such as "if, in, let, with, ...". In your case, the "dtml-var" is simply not recognized and treated as a string rather than expanded. I assume (though I am not sure), that "ZopeTime" is a "DateTime" object. In this case, you could use: <dtml-if "date1 == ZopeTime.Day()"> Dieter

Serious problems upgrading to 2.1.6...
by Skip Montanaro 30 May '00

30 May '00

I'm trying to upgrade a ZServer-only environment from 2.0.0 to 2.1.6 and am experiencing serious problems. I'm using the RPMs available from http://starship.python.net/crew/jrush/Zope/Zope216.html I downloaded the A bundle and the zserver option from the C bundle. I then installed them using rpm -u -v -h Zope-2.1.6-1.i386.rpm Zope-zserver-2.1.6-1.i386.rpm My main Zope server seems to have adapted to this just fine, however, I am also running a ZServer-only setup listening on 127.0.0.2:9673 (sitting behind an Apache proxy). This is where I'm having trouble. When the RPMs installed, they stuck Python modules in both /usr/share/zope and /usr/lib/python1.5/site-packages. My startup script finnagles sys.path to ['/usr/share/zope/ZServer', '/usr/lib/python1.5/site-packages/DocumentTemplate', '/usr/share/zope/lib/python', '/usr/share/zope', '/home/dolphin/skip/cmd', '', '/usr/lib/python1.5/', '/usr/lib/python1.5/plat-linux2', '/usr/lib/python1.5/lib-tk', '/usr/lib/python1.5/lib-dynload', '/usr/lib/python1.5/site-packages', '/usr/local/lib/automatrix/python'] The last directory contains my application software. In particular, it contains the single module that gets published. The first time I try to access the ZServer via the proxy I get an ImportError:  This suggests to me that the mxDateTime module isn't being imported. When I try to import things manually from the interpreter prompt, I get an ImportError for something called ts_regex: % pwd /usr/lib/python1.5/site-packages % python Python 1.5.2+ (#4, Mar 20 2000, 10:02:10) [GCC pgcc-2.91.66 19990314 (egcs-1.1.2 release)] on linux2 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam >>> from DateTime import mxDateTime Traceback (innermost last): File "<stdin>", line 1, in ? File "/usr/lib/python1.5/site-packages/DateTime/__init__.py", line 85, in ? from DateTime import DateTime File "/usr/lib/python1.5/site-packages/DateTime/DateTime.py", line 90, in ? import sys, os, math, regex, ts_regex, DateTimeZone ImportError: 'No module named ts_regex' which turns out to live in the DocumentTemplate package. It's a little bit of a miff that the RPMs install stuff in the site-packages directory that can't stand alone, especially stuff like MAL's DateTime package that should be able to stand alone. As you can see from the first traceback, I'm using DateTime via the MySQLdb module. It's quite likely that I've screwed up my directory tree and sys.path somehow, but I was hoping someone out there could see what I've done wrong or what might be done to correct the damage installing the RPMs has done. Is it safe to just reinstall MAL's DateTime package back over the busted one that came with the RPMs? Any feedback would be appreciated.
