calling getOwner on an ExtFile instance raises an Unauthorized ex ception
by Palermo, Tom 15 Feb '06

15 Feb '06

All, Does anyone know why calling getOwner() on an instance of ExtFile raises an unauthorized exception? Error Type: Unauthorized Error Value: You are not allowed to access 'getOwner' in this context ExtFile imports SimpleItem which, in turn, imports AccessControl.Owner Here's the code from ExtFile: from OFS.SimpleItem import SimpleItem Here's the code from SimpleItem: import AccessControl.Role, AccessControl.Owned, App.Common I've got some other custom objects in my application which import SimpleItem and I am able to call getOwner() on them no problem. Thanks, Tom

Do you know of any better suited frameworks or even existing systems that we should use? Finally if we do settle on Zope, would we be wiser using the 2.x version or the 3.x version? I imagine that 2.x has more documentation and more addons (e.g. for versioning, workflow etc.). > Another consideration is that the skillset here is mainly in PHP and > Java, however I don't think anybody is fazed by having to use Python > if Zope is the best option for us.

Zope won't start on Windows XP
by Holger Butschek 15 Feb '06

15 Feb '06

I'am triing to install Zope 2.9 on my laptop to work withit when not connected the the internet. The installation-routine runs through without any errors. An instance is created in the folder C:\instance. When I now want to start zope in c:\instance\bin by typing runzope.bat the only thing that happens is a big exception thrown by zope. Do you have any ideas what to do? No other service is actually running on port 8080. The service of zope is not installed/activated.

workflow products

All, Are there any workflow products available for Zope 2.x that do not require either Plone or CMF? It looks like there aren't but I thought I'd ask first. Thanks, Tom

context and URLs
by Ole Johan Tennvassås 14 Feb '06

14 Feb '06

Sorry for late reply - have been away. Cant get this to work! I hope I can avoid to use an absolute URL path. What i want is, as you say, to let the server generate as much of the URL as possible. To be more spesific, the zpt whith the calling href (located in "folderA") calls a script with a construct like this: <a tal:attributes="href string:folderB/scriptobject?Parameter=$variable">Text</a> The effect of this is that Zope generates a link to the URL http://myserver/application/folderA/folderB/scriptobject?... and after this link is used to call the script in folderB, the script calls a zpt in folderA again. Now, all links in this zpt gets /folderB added in their path! If you have some more tips about this, or could point me to some examples or documentation that could explain to me how this is supposed to work, it would be great! Regards Ole >Instead of writing links like this:: > > <a href="folderB/object">object</a> > >write them like this:: > > <a tal:attributes="href folderB/object/absolute_url_path">object</a> > >I know it's more typing but it will solve all your problems.

I'm trying to get MailDropHost running under windows, but it errors with: Traceback (most recent call last): File ".\maildrop.py", line 296, in ? pid = os.fork() AttributeError: 'module' object has no attribute 'fork' Altering it to run without threading seems to work quite well.

TextIndexNG extensions for Windows, please share if you have them
by Owen K 14 Feb '06

14 Feb '06

Do you have TextIndexNG (2 or 3) extensions for Windows that work with Python 2.3.5 ? If yes, please share them ! :) Although there are some files on sf.net that are labelled for python 2.3 (TextIndexNGExtensions-2.02.win32-py2.3.exe, python-Levenshtein-0.10.win32-py2.3.exe) one of these throws the following error error: Python was built with version 6 of Visual Studio, and extensions need to be built with the same version of the compiler, but it isn't installed. Or perhaps you are already using exactly those files with Python 2.3.5, in which case I would conclude that the error I see is somehow misleading. Thanks, Owen

restricting permissions for direct access only
by Michael Shulman 14 Feb '06

14 Feb '06

Hi, I am new to Zope, and so far I like it very much. But I think I am confused about how security works, or is supposed to work. Specifically I want to know the following. Is there a way in Zope to restrict permissions for direct access only (i.e. calling an object through the web) but still allow indirect access (i.e. executing an object that was called by another object that was called through the web)? I have many Zope scripts but most of them are only auxiliary functions; only a few are designed to be accessed by a user through a URL. I don't want users to be able to call my auxiliary scripts directly, only the ones that are designed to be "published." But changing the security settings on the auxiliary scripts (e.g. removing "View" access from "Anonymous" role) prevents anonymous users from executing them even indirectly, so the public objects which depend on those auxiliary methods also stop working. Feel free to tell me that I am misunderstanding the way security works, or is supposed to work, in Zope, or that if this is something I need to do I am designing my site incorrectly from the point of view of Zope security (and if so, what is the correct way to design it?). Thanks!! Mike
