Restricting access to zope site
by John Poltorak 06 Mar '05

Is there any way of restricting access to a particular zope site to an internal network? I'm referring to one zope site rather than all sites within a zope instance. -- John

Access to Data.fs without Zope ?
by jurgen.defurne＠pandora.be 06 Mar '05

06 Mar '05

Hello, Last summer I wrote an application to inventarise all my media (books, CD's, periodicals, etc) which worked well, but wasn't yet complete. Anyway, I started adding books as an exercise to see how it could be improved. However, I run Debian testing, and after some updates in the fall I could not get access anymore to my data. Today I tried to move the contents of Zope default to a known running instance of Zope, but the moment I do that, the Zope instance cannot be started anymore. Replace the contents back by its originals and the instance can be started once again. So, is there a way to access the contents of the Data.fs file without using Zope alltogether, so that I at least can start working again ? Regards, Jurgen

ZMySQLDA-2.0.9b3 released
by Andy Dustman 06 Mar '05

06 Mar '05

https://sourceforge.net/project/showfiles.php?group_id=22307&package_id=381… This release fixes the problem of MySQLdb-1.0.0 and newer returning BLOBs as character arrays, and returns them as strings. It also should be a bit more robust if connections time out. I would really like to get some feedback on this release within the next week so I can make a final release for 2.0.9. Here's an open issue: Should character data be returned as unicode? It probably wouldn't be hard to implement, but I wonder how much other stuff would break. There's already a ton of stuff being stuffed in the connection string, but it probably needs to be a connection option, doesn't it? -- Computer interfaces should never be made of meat. Using GMail?

jonathan sir , thanks for that detailed solution. but i guess my problem was simpler. i cudnt explain it properly . I've to rebuilt a login page in zope which i'd developed in asp. I'd used javascript to do wat u've mentioned in 3rd soln. but the javascript is not at all being executed in zope. This is wat i wanted : as soon as i select a district from a combobox the corresponding user list in next combobox sud appear.the data are being fetched from Mysql using the ZSQL queries. AND CAN WE ANYWAY USE JAVASCRIPT IN DTML DOCUMENTS. please tell me the soln in ZOPE.

Post authentication hook and anonymous users
by Cyrille Bonnet 04 Mar '05

04 Mar '05

Hi Zope people, I have been using Dieter Maurer's Post authentication hook quite successfully to restrict access to a folder for a group of users. Now, my problem is that Post authentication hook is only called... for authenticated users (as its name implies). That's a problem for me, because anonymous users that can guess a URL could access private areas that I have set up. (BTW, I am aware that I could restrict the access by changing the "View" permission in the "Security" tab and remove "Acquired", but that's not good enough: it then shows all documents to authorized users, regardless of their worflow state). Anyway, I am thinking of adding an unvalidated_hook call in ZPublisher/BaseRequest.py, something like: if user is not None: if validated_hook is not None: validated_hook(self, user) request['AUTHENTICATED_USER']=user request['AUTHENTICATION_PATH']='/'.join(steps[:-i]) else: unvalidated_hook(request) And then in unvalidated_hook, I would dynamically check if anonymous users can access the current folder. Am I on the right tracks or is there a built-in functionality in Zope to accomplish what I am trying to do?? Advice and pointers are welcome. Cheers Cyrille
