Zope/WebDav issue
by Gautam Saha 16 Jan '04

16 Jan '04

Hi: I am trying to use WebDav to upload files to my zope server, and doing some reading on how this works. I looked at : http://webserver.cpg.com/wa/4.4/ and found reference of " Zope/WebDAV Test Server <http://webdav.zope.org/>" at http://webdav.zope.org/ . But seems like the URL is broken. 1. Can anyone point me to some Zope/WebDav resources? 2. What is the default WebDav Port if my zope.conf settings are: PORT_BASE=8000 DAV_SOURCE=1 3. Do I have to to set DAV_SOURCE_PORT also? 4. I am using Dreamweaver to upload via WebDav. Is there any specific setting I have to set there to work it for zope? I am using PORT_BASE +80+1000 (=9080) for my webdav port. Is this the correct way to get the Webdav port? Thanks, Gautam Saha

Zope 2.7, Py 2.3.3 Problem with
by Gfeller Martin 15 Jan '04

15 Jan '04

Dear all, the following DTML worked fine in Zope 2.6.2/Py 2.1.3: <dtml-let v="[x for x in ['a','b']]"> <dtml-var v> </dtml-let> Under Zope 2.7.0-b4 (python 2.3.3, win32), it fails with a NameError name '_getiter_' is not defined. The example is a variation of some actual code, stripped down to just expose the actual problem - in reality, we do something sensible with 'x' :-). Any idea about the cause?

python Script to download a file
by Hervé Richard 15 Jan '04

15 Jan '04

Hi list, I write a python script which return a selected file to download. The script receive value from a form to choose the kind of file to download (and increment the counter of the file selected): For example, in a folder i have 2 files ("A.tgz" and "B.tgz") and a Page Template Object (chooseFileToDownload.html). This page is a form with multiple choice in order to seclect a file to download (if the user select "A" button, he must get the A.tgz file, if select "B" he must get A.tgz ...) I write the python script method to select the file but i don't know how the script sends the file to download: With the variable "fileToDownload" which contain the name of the file selected, if i write "return fileToDownload" in my script i get all the file (in his compressed format) in my navigator windows, but *no* a popup windows which ask me where i want to save the file like we have any time we want to download a file. Thanks for any help ! _______________________________________________ Hervé RICHARD Herve.Richard(a)avignon.inra.fr INRA - Biometrie _______________________________________________

Type Error
by Asad Habib 15 Jan '04

15 Jan '04

I am getting the following error. Error Type: TypeError Error Value: __setitem__() takes exactly 3 arguments (2 given) I am not directly calling __setitem__ so it's probably being invoked by a dtml-tag. Does anyone know which tags/methods rely on this function? Any help would be greatly appreciated. Thanks. - Asad

CMFStaging, ZEO
by Michael Havard 15 Jan '04

15 Jan '04

Does anyone have any tips for setting up CMFStaging. I'm just starting to fumble my way through it and I've only found two posts with any real information about setting it up. Essentially my architecture is this: Three separate machines: DEV QA PROD We're running Plone and ZEO. We need to be able to develop templates et al on DEV, test on QA and eventually migrate those templates, workflows, security etc. to PROD. In PROD we have content authors who create new content (in real time) using a customized DCWorkFlow. We'd like to have the ability to keep the authors content separate from the application templates and security. I'm assuming to do that we just need seperate databases using a different mount point or do we have to use a product to accomplish that. Anyone with some real world experience doing something similar? _________________________________________________________________ Scope out the new MSN Plus Internet Software optimizes dial-up to the max! http://join.msn.com/?pgmarket=en-us&page=byoa/plus&ST=1

ZSyncer and acl_user permissions
by Kamal Gill 15 Jan '04

15 Jan '04

How does one enable a user to use a ZSyncer instance at the root folder if the user has an acl_users account at folder /spam/eggs/ (for example) but not at the root folder? I would like a user to be able to sync content only in the /spam/eggs/ folder (and its subfolders). My ZSyncer is at the root folder, but I do not want to give the user Manager permissions at the root folder. I created a new role called "Sync" at the root folder, but I'm not sure what permissions I need to enable in order to allow the user to access the operations of the ZSyncer at the root folder. I've enabled the "Use ZSyncer" permission for the "Sync" role, but this does not seem to be adequate. Any ideas? - Kamal

Well, we still run out of memory, and then it's useful to know why. :) Caring about memory usage is caring about (one kind of) scalability. I realize I can't change this aspect of Python, and it's not that critical to know if you can deduce memory usage from pickle sizes (like you mention).

Any chance of seeing these changes in the core? [...] The remainder of my use cases can be currently best supported by using a debugger + DocFinder, I agree, although I think there's still a need for an admin tool that lets you easily view and browse (multiple) objects, independent of if they catalogaware or has an ZMI interface. I'll think so more about it. Thanks for all the help. -- Bjorn

I've been trying to install a brand new Zope 2.6.3 with CMF 1.4.2 and all of the goodies and ran into the same troubles. Downloadarea of PTS is currently down due to the compromise of Savannah :-( Installed itools after Localizer kept muttering about it to find out that itools expects Python 2.3 according to parsers.py while I only have 1.5, 2.1 and 2.2 installed. itools keeps complaining about HTMLParser ...
