I feel your pain! ;) Don't call addPerson from your form. call a DTML method that uses . You can then display info or do a redirect somewhere else. A good approch to get started is to use the Add "Z Search Interface" to create all the parts for a SELECT then edit the methods to do INSERT and UPDATE. (Usually you will want a SELECT at some point anyway!) Good Luck. Phil. ----------------------------------------------------------- Philip Aylesworth mailto:purple@mnsi.net

Authentication
by julian＠zereau.net 22 Feb '99

22 Feb '99

I want to be able to: * Gather user login and password with a cute login screen of my own devising, not that messy HTTP authentication popup, * Check the username/password pair against the unix /etc/passwd database, and on success log the user into Zope as that username. Is this possible? If so, how? --- Julian Morrison Programmer (Zereau Ltd)

Fortunately it is possible to use cookies to get around that. Take a look at the UserDB sample application for more details. (Note: we don't support the UserDB sample application, it is just an example.) > * Check the username/password pair against the unix > /etc/passwd database, and > on success log the user into Zope as that username. The UserDB sample stores and retrieves user information from a relational database. Thus, it provides an example of how to extend Zope to get user information from an external source.

Tabula / Z Tables question
by WWW Admin 22 Feb '99

22 Feb '99

hello all, many of our customers use microsoft access to store all their relevant company data. it seems tabula is what we need in order for our customers to publish their access based product directories. hopefully somebody at digital creations can answer these questions. i read on this list that tabula would be integrated into zope anybody know the time frame? will Z table be a subset of tabula (i.e. not offer the same features)? our designers need to be able to predefine layouts (create templates) with the data originating from an access file. ideally the customer would just drop in a new access database file whenever his prices or products change without affecting the rest of the website. any foreseeable problems here (i read that when you delete a tabula object it erases everything related to it)? our zope system would most likely be an intel linux based machine tied to sybase. is tabula availible for linux? regards, webman --------------------------------------------------------------------------- webman | _ beehive GmbH | ASCII ribbon campaign ( ) berlin, Germany | - against HTML email X http://www.beehive.de | & vcards / \

FYI: Bug in object caching
by Paul Everitt 22 Feb '99

22 Feb '99

FYI...Jim found a bug in the object caching code that basically made it not deactivate things. I believe Scott Robertson reported that he saw no effect from the cache removing things, so this should address that. I believe it is going into 1.10. --Paul

WinNT & time zone woes
by Brian Hooper 22 Feb '99

22 Feb '99

Hi there - I and a colleague have been working with Zope on WinNT with MySQL/ODBC as the database, with generally very good success. Zope is awesome! However, in one particular situation we noted the following strange behavior - MySQL select queries were mysteriously failing with a parse error in RDB.py, related to not being able to parse a DATETIME field. After looking at DateTime.py and concluding that DateTime should be able to parse virtually anything ;-), we were initially very puzzled as to the cause of the parse error. However, after eliminating everything else we could think of, we finally found that it was the fact that NT was returning the value 'Tokyo Standard Time' as the timezone for our machine - a value which is not listed in the _zmap in DateTime - so, DateTime was failing here: # Current time, exp in specified timezone t,tz=time(),self._tzinfo._zmap[lower(arg)] We added the mapping 'tokyo standard time':'Tokyo' to _zmap, restarted Zope, and now everything's working fine. However, when I looked into implementing the same fix on my Japanese NT Server machine, I found that python's time.tzname gives me back 'PST' even though my machine is set for Japan's time zone :-( . A suggestion: Would it be better to get the numerical time zone via time.timezone and then convert it to some set string for each time zone, rather than rely on time.tzname? Incidently, with the Solaris installation of Zope I have, Japan's time zone is given as 'JST', which would also require an entry in DateTime to avoid an error similar to the above. _zmap is useful for parsing date strings, but should it be used to determine the time zone when a more sure method is available? Thoughts, anyone? --Brian

Re: [Zope] size of text area in "Edit" view of Documents...

Netscape 4.5 - but I think I've tracked the problem down to having cookies turned off. At least, if I turn them on, the problem disappears (I should have thought of that before :-) Incidentally, just in case you've also tried this, I found a default definition for "dtpref_cols" in "Document.py" and changed it to '100', but to no effect. Is there some other place I need to change something to alter the defaults? > >A second query is - can I save the DTML from the edit view to a file, > >edit the file, and then upload the result to replace the original DTML? > >(Which might be far faster than using the browser window's non-existsent > >editing abilities :-) > > Using ZServer you can use FTP to get the DTML source, and put it back the same > way. I can't get this to work - possibly because I already have an ftp server at the same site. But then I'm not sure I'm using Zserver - is that the same thing as "serve.sh" starts? If I *was* using ZServer, then how would I get ftp to connect to it rather than a default ftp server at the same site? (I'm using Zope's 1.9 release).

Question on Performance
by LEE, Kwan Soo 22 Feb '99

22 Feb '99

I have come to two performance question on the Zope(may be). 1. Which is better, a faster processor or larger ram, to get quicker response? 2. Which is quicker, depending strictly on DTML or using an External Method, to pit out selected static contents from about 200 DTML document. uhhh, well, I heared that performance issue and benchmarking are dependent on so many circumstance and too complex a witchcraft that I can not understand. So what I want is a general rule for a dummy. I have come to the above questions, when I uploaded 277 static documents which is spitted by a DTML Document. That DTML Document compares the request with the id's of the 277 files and select some of them to spit out. Not so clever to write down an elegant DTML codes, I wrote down an External method and found that the External Method response quicker then my simple minded DTML codes(the E-method and the DTML documents are called by another DTML document). Still the quicker response is desired. My Zope is running behind Apache through pcgi on a linux box with 28MBytes RAM and 133 MHz Pentium(actually this box runs 3 instance of Zope + apache and usually a dummy(more dummer than me) is using Netscape). TIA. LEE Kwan Soo.

splitting the mailing list?
by Michael Olivier 21 Feb '99

21 Feb '99

As a newcomer to this list, I am finding myself overloaded by the level of traffic (>50 messages/day it seems), and wonder if there are one or more natural split points for the mailing list. PostGreSQL has about 6-8 mailing lists (see www.postgresql.com) and that seems to work well... The thought of "live with the traffic or go away" just seems so punitive :) ... it's hard to decide what I need to read - what applies to me - so I'm left to choose between reading more than I can really afford to and not reading enough and being way in the dark. Could the list be divided along lines of - functionality? - type of work being done? - background or Zope skill level of individuals? I'd personally love a mailing list that was for web server "lightweights" using Zope, Apache, and Linux. If there was some way to divide up the discussions, it would really help me and others coming into the fray. The traffic is only going to get heavier as more folks start using Zope. (A "good problem" for DC, as they say.) --Michael _________________________________________________________ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com

To answer your question about .conf files, the Apache people have consolidated them all into one file, httpd.conf. srm.conf and access.conf are depreciated and should not be used with newer versions of apache. -Michel > --Michael > > _________________________________________________________ > DO YOU YAHOO!? > Get your free @yahoo.com address at http://mail.yahoo.com > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope >
