Is webdav just pre-beta or what? It just doesn't seem to be working right at all. Is there a Zope-Webdav tutorial or faq or something I can get my hands on that might help me? Thanks ahead of time for any help, Luis.

[ZClass constructor question]: How can I copy objects into my container class?
by Simon Brogden 22 Nov '01

22 Nov '01

Hi All, I'm (banging my head against the desk) writing to write a ZClass that inherits from ObjectManager and can contain other objects (DTMLMethods & Images). When an instance of the class is created I want to copy/create a couple of default DTML methods inside the instance, so the user can modify them. Trouble is, the methods appear at the same nesting level as the class is created at, not contained within it. I'm putting the create/copy call inside the class constructor method: <dtml-call "manage_addProduct['OFSP'].manage_addDTMLMethod(....)> I've trawled the how-to's & the example products (the "How to: Build a searchable job board" is excellent BTW) to no avail. Does anyone know where I'm going wrong? Cheers, Simon.

Zope-specifics of cPickle
by Stephan Herschel 21 Nov '01

21 Nov '01

Hello, In Python it's possible to use the cPickle module to dump objects (instanciated classes). This is not possible in zope's version of cPickle. What's the reason for this difference? Thanks, Stephan

Authentication problem / IE
by belen＠netcom.no 21 Nov '01

21 Nov '01

Hello , I have a problem regarding authentication and I do not know if authorisation. Users working IE5.01 SP2 cannot access my site. To enter it, I force them to login. When they do, their login and password is not rejected, but if I display their role/s and user name on screen it is Role: ('Anonymous',) Name: Anonymous User. Some of the access of my site is granted by checking that their role is not Anonymous, (tried also their user name is not 'Anonymous User'), therefore they cannot access. Surprisingly one of these users has Manager role. He still cannot access those parts of the site...but he can access the management screens of the site and access its content objects. Somehow zope still "knows" that he is not anonymous. This problem does not occur with IE 5.5 and IE 4.0. Has anyone have a clue of what happens. Could someone please point me to the solution? Thanks in advance for your help. Belen

Session Management for keeping Python-Objects
by Stephan Herschel 21 Nov '01

21 Nov '01

Hello, I have an external method that returns a python-object to zope. Inside zope i would like to be able to store the object as a session variable in order to have access to this object inside one session. I have tried to do this using FSSession, but it's not able to pickle objects to a file. Which session management product would you propose for doing this? Thanks for any input, stephan

Zope restarting every 5-10 minutes
by Gitte Wange 21 Nov '01

21 Nov '01

Hello, I have discovered a rather nasty problem with our Zope installation. We run both Zope 2.3.2 and Zope 2.4 on our server but we are migrating all our sites for 2.4 (but it takes time). One thing that bothers me with the 2.4 installation is that it restarts every 5-10 minutes - and I can't seem to figure out why. We run it on a Linux Mandrake 8.0 server ... I have searched the log file - but no go (or the only log file I could find is the Z2.log file) ... We have Apache in front of the ZServer so every 5-10 minutes we get a Proxy Error .... I have looked in to the mailing list archives and have discovered a lot of people with similar problems ... the only minor fix I could find was to upgrade to 2.4.1 ... but will this help ??? -- Gitte Wange Jensen Sys Admin, Developer and a lot more MMmanager.org Aps, Denmark Phone: +45 29 72 79 72 Email: gitte(a)mmmanager.org Web: www.mmmanager.org Quote of the day: In short, go away until you can behave. - Linus Torvalds

please take a look at this, it's probably really easy, but I'm totally stuck
by Jacob Singh 21 Nov '01

21 Nov '01

So here is my tragedy: I have an SQL query which pulls a record from a database. One of the fields is called file1. It contains a path to a file (i.e. media/inline/asdasd.jpeg). This file is accessible through LocalFS. LocalFS requires a syntax like media['inline']['asdasd.jpg'], so I wrote a script to convert the Unix style path to something LocalFS can understand. This works fine. Here is the code I use in my DTML doc to render asdasd.jpg: <dtml-call expr="REQUEST.set('imgpath',makeLocalFSPath(file1))"> <dtml-var "_.getitem(imgpath,1)" null="_[media['none.gif']]"> The first line calls the pythinon script that will make the LocalFS path. The second one endeavors to render the image using DTML's built in MIME to HTML technology which is necessary because using <IMG src=..... would not give me the with and height and is bad practice anyway. The null tag is just to shove that empty image marker in in case there is nothing in the field. When I call the page it gets a key error Error Type: KeyError Error Value: media['inline']['asdasd.jpeg'] But if I put <dtml-var "media['inline']['asdasd.jpeg']"> in any document in renders just fine. So basically the variable value gets rendered, but since It's not a variable but an expression, Zope doesn't know what to do. Oh and I tried putting double quotes on imgpath via the makeLocalFSPath function to no avail. Thank you for your help Jacob

ZMySQLDA Problem
by Ben Ocean 21 Nov '01

21 Nov '01

Hi; I followed the instructions to install ZMySQLDA but ran into problems. First up, it appears that I do have the necessary python modules: [root@hermes i386]# rpm -qa|grep MySQL MySQL-client-3.23.42-1 MySQL-3.23.42-1 MySQL-devel-3.23.42-1 ...and make -f Makefile.pre.in boot goes smoothly, but when I try make I get this: [root@hermes src]# make gcc -fPIC -g -O2 -Wall -Wstrict-prototypes -I/usr/include/python2.1 -I/usr/include/python2.1 -DHAVE_CONFIG_H -I/usr/local/mysql/include -I/usr/include/mysql -c ././MySQLmodule.c -o ./MySQLmodule.o ././MySQLmodule.c:199: warning: function declaration isn't a prototype ././MySQLmodule.c: In function `clear_channel': ././MySQLmodule.c:204: warning: suggest parentheses around assignment used as truth value ././MySQLmodule.c: At top level: ././MySQLmodule.c:217: warning: function declaration isn't a prototype ././MySQLmodule.c:229: warning: function declaration isn't a prototype ././MySQLmodule.c: In function `pythonify_row': ././MySQLmodule.c:238: warning: assignment from incompatible pointer type ././MySQLmodule.c: At top level: ././MySQLmodule.c:339: warning: function declaration isn't a prototype ././MySQLmodule.c: In function `pythonify_res': ././MySQLmodule.c:344: warning: `thisrow' might be used uninitialized in this function ././MySQLmodule.c: At top level: ././MySQLmodule.c:373: warning: function declaration isn't a prototype ././MySQLmodule.c: In function `pythonify_res_fields': ././MySQLmodule.c:384: invalid lvalue in unary `&' ././MySQLmodule.c:378: warning: `tf' might be used uninitialized in this function ././MySQLmodule.c: At top level: ././MySQLmodule.c:483: warning: function declaration isn't a prototype ././MySQLmodule.c:502: warning: function declaration isn't a prototype ././MySQLmodule.c:530: warning: function declaration isn't a prototype ././MySQLmodule.c:562: warning: function declaration isn't a prototype ././MySQLmodule.c:580: warning: function declaration isn't a prototype ././MySQLmodule.c:607: warning: function declaration isn't a prototype ././MySQLmodule.c:634: warning: function declaration isn't a prototype ././MySQLmodule.c:662: warning: function declaration isn't a prototype ././MySQLmodule.c:688: warning: function declaration isn't a prototype ././MySQLmodule.c:722: warning: function declaration isn't a prototype ././MySQLmodule.c:734: warning: function declaration isn't a prototype ././MySQLmodule.c:753: warning: function declaration isn't a prototype ././MySQLmodule.c:767: warning: function declaration isn't a prototype ././MySQLmodule.c:779: warning: function declaration isn't a prototype ././MySQLmodule.c:796: warning: function declaration isn't a prototype ././MySQLmodule.c: In function `DBH_clientinfo': ././MySQLmodule.c:799: warning: unused variable `info' ././MySQLmodule.c: At top level: ././MySQLmodule.c:815: warning: function declaration isn't a prototype ././MySQLmodule.c:832: warning: function declaration isn't a prototype ././MySQLmodule.c:849: warning: function declaration isn't a prototype ././MySQLmodule.c:866: warning: function declaration isn't a prototype ././MySQLmodule.c:885: warning: function declaration isn't a prototype ././MySQLmodule.c:902: warning: function declaration isn't a prototype ././MySQLmodule.c:920: warning: function declaration isn't a prototype ././MySQLmodule.c:973: warning: function declaration isn't a prototype ././MySQLmodule.c:986: warning: function declaration isn't a prototype ././MySQLmodule.c:994: warning: function declaration isn't a prototype ././MySQLmodule.c:1032: warning: function declaration isn't a prototype ././MySQLmodule.c:1040: warning: function declaration isn't a prototype ././MySQLmodule.c:1070: warning: function declaration isn't a prototype ././MySQLmodule.c:1085: warning: function declaration isn't a prototype ././MySQLmodule.c:1102: warning: function declaration isn't a prototype ././MySQLmodule.c: In function `STH_fetchdict': ././MySQLmodule.c:1125: invalid lvalue in unary `&' ././MySQLmodule.c:1147: invalid lvalue in unary `&' ././MySQLmodule.c:1111: warning: `tf' might be used uninitialized in this function ././MySQLmodule.c: At top level: ././MySQLmodule.c:1176: warning: function declaration isn't a prototype ././MySQLmodule.c:1192: warning: function declaration isn't a prototype ././MySQLmodule.c:1201: warning: function declaration isn't a prototype ././MySQLmodule.c:1210: warning: function declaration isn't a prototype ././MySQLmodule.c:1225: warning: function declaration isn't a prototype ././MySQLmodule.c:1234: warning: function declaration isn't a prototype ././MySQLmodule.c:1257: warning: function declaration isn't a prototype ././MySQLmodule.c:1265: warning: function declaration isn't a prototype ././MySQLmodule.c:1296: warning: function declaration isn't a prototype make: *** [MySQLmodule.o] Error 1 What are all these warnings and what have I done wrong?

exUserFolder, docLogin, cookie-based login
by Milos Prudek 21 Nov '01

21 Nov '01

--I can't figure how to design cookie-based XUF login with Netscape 4.x. XUF seems to generate incorrect HTML that only MSIE can cope with. I need a different docLogin than the stock docLogin. I want to use acquisition: - I modified docLogin very slightly (only added some text), and saved it in the Zope root. - created exUserFolder in my FOLDER1. - deleted docLogin from the contents of that instance of exUserFolder. - created a LOGIN dtml method in FOLDER1. This login method limits "View" and "Access contents" permissions to Authorised role. Therefore it should trigger cookie-based login. When /FOLDER1/LOGIN is accessed, the following html is generated: [standard html header contents] <html> <head><title>Logging In</title> <META HTTP-EQUIV=Expires ...> <META HTTP-EQUIV=Refresh Content="0; http://localhost:8080/FOLDER1/acl_users/docLogin?destination=http://localho…"> </head><body></body></html> [standard html footer contents] The trouble is of course the [standard html header contents] and [standard html footer contents], because they ALSO contain <html><head> and </body></html>, respectively, and therefore they confuse Netscape. I tried to work around the problem by directing uses to click on the following link directly, instead of accessing a protected LOGIN page: <a href=http://localhost:8080/FOLDER1/acl_users/docLogin?destination=http://localhost:8080/FOLDER1/LOGIN> This approach lets users log in, but if they submit incorrect password, they are again presented with the "double head-double body" page described above. Oh, and I made sure that docLogin does NOT contain any references to <dtml-var standard_html_header/footer>, but this problem is somewhere else... Zope 2.4.3, exUserFolder 0.10.0 -- Milos Prudek

Is anybody using StructuredText tables ?????
by Robert Rottermann 21 Nov '01

21 Nov '01

I am trying hard to use StructeredText tables. However the only table featuring more than one line that is rendered correctly seems to be the one in the ST test suite. So if anybody could point me to an explanation of how to use tables (I did read the StructuredTextNG rules) or provide me with some more examples I would be very grateful. Robert
