User groups
by Etienne Labuschagne 05 Sep '03

Hi all, Is there a product available that would enable me to make user groups in Zope and assign local roles to the group, rather than the individual users. I want to use this in a multi-party CMF portal. I want to create a group for each party (be that a company, organisation, whatever) and then assign user, reviewer, etc. local roles to the group instead of each user. I would be easy enough to write this so that the group object handles the individual user local role assignment and removal, but something a bit closer to the Zope security system would be preferable. Thanks Etienne

Cannot pack Data.fs, Permission Denied error
by Jon Whitener 05 Sep '03

05 Sep '03

I (still) cannot pack my ZODB via the Web. This has been vexing me for months. I get this error: Error Type: IOError Error Value: [Errno 13] Permission denied: '$ZOPEDIR/var/Data.fs' I am running Zope on port 80, so I changed the ownership of the $ZOPEDIR/var directory to root. Zope is started as root, but with the "-u zopeUser" option (yet the first zope process is still owned by root (see below) is that right?). Are there some other permissions I need to change to be able to pack the database via the Zope Management Interface? (Changing all the contents of var to root ownership did not fix.) Here are my data: [root@zopeServer var]# ls -ld drwx--x--T 3 root root 4096 Sep 3 17:44 .

maintaining consistent security settings across cloned sites
by Dennis Allison 05 Sep '03

05 Sep '03

I'm looking for a tool that will help maintain security settings, having been burned a couple of times. What I need is: 1. A tool to traverse a site and build a database of security settings that must be set for each of the various roles. Ideally this would remove redundancies and, perhaps, raise warnings when settings look strange. 2. A tool to apply said database to a site which is similar but, perhaps, not identical in structure--that is, some extra folders(and enclosed material) might appear in one site and not in another. 3. It would be nice if the security settings database could be read and edited off-line so they could be reviewed and corrected as a unit. 4. It has to be able to handle proxies. 5. It has to be able to handle roles beyond the usual Anonymous, Authorized, Manager, and Owner. It's OK to demand that both sites have the same user defined roles. Anyone done anything like this?

You are not allowed to access ...., even allowing ?!
by Bernhard Kahlbacher 04 Sep '03

Hi, I'm writing a Product called "Groupware" which shoud provide minimal Groupware Function. As a Database System I decided to use PostgresQL and my DB-Connection Class (writen in python using psycopg) allready works perfectly (outside Zope). But now I'm not making any progress since serveral days. After I added the Groupware Product in the ZMI, I added a "Python Script" and just added one line to import my DB-Connection Class (Filename DB.py, the class itself I name "database") in the python script: ----- from Products.Groupware.DB import database ---- Then the browser starts a HTTP-Authentification which results in Error Type: Unauthorized Error Value: You are not allowed to access Groupware in this context In my __init__.py I inserted the following lines to allow an import import Groupware from ImageFile import ImageFile from Products.PythonScripts.Utility import allow_module, allow_class from AccessControl import ModuleSecurityInfo, ClassSecurityInfo from Globals import InitializeClass from DB import database allow_class (database) ... ... The DB_Connection Class works ouside Zope what on earth can I do to make it working inside zope? Any help would be greatly appreciated. Bernhard Kahlbacher

session confusion
by Michael Hauser 04 Sep '03

04 Sep '03

I'm trying to create dynamic charts with ZGDChart and a python script by passing values to the script from a page template form using session data. It's working correctly in Mozilla. However, in Internet Explorer, it only works correctly the first time the form is submitted. After that, the chart continues to use the initial values each time. I can see that the session data values are getting updated but the script isn't getting the new values. Below is an example that illustrates the behavior. Any suggestions as to what might be going on? I create a default ZGDChart object and set it to Chart Type "Line_2D" and then select Python Script as the Data Method and test.py as the selected script. ------------ test.py ------------- session = context.session_data_manager.getSessionData() return [(i, i) for i in session.get('start'), session.get('end')] ------------ test.pt ------------- <html> <head> <title tal:content="template/title">The title</title> </head> <body> <div tal:define="global submit request/form/submit | nothing"> <form action="test.pt" method="POST"> Start: <input tal:attributes="value request/form/start | nothing" type="text" name="start" value=""><br> End: <input tal:attributes="value request/form/end | nothing" type="text" name="end" value=""><br> <input type="Submit" name="submit" value="Plot Specified Range"> </form> </div> <div tal:condition="submit"> <span tal:define="dummy python:request.SESSION.set('start', request.form.get('start')); dummy python:request.SESSION.set('end', request.form.get('end'))"> <p><b>Plotting range from <span tal:content="request/form/start">start</span> to <span tal:content="request/form/end">end</span></b></p> <img src="testchart"> </span> </div> </body> </html>
