Deleting objects from DTML
by Martin Grabmueller 13 Oct '99

13 Oct '99

Hello fellow Zopers, I tried to find an object reference manual, but had no success, so here is my question: Can anybody give me a hint how to delete/destroy/kill a Zope object from within a DTML method? The background is that I try to have a link on a web page which deletes an object from the Zope DB when klicked. TIA, mgrabmue -- Pinuts media+science GmbH http://www.pinuts.de Martin Grabmueller mailto:grabmueller@pinuts.de Potsdamer Str. 96 voice: +49 30 590090324 D-10785 Berlin fax: +49 30 590090390

Turn static HTML dynamic?
by User Webteam 13 Oct '99

13 Oct '99

Hi! We´re thinking about using Zope for our University website. Now we face following problem: We need a simple solution for people who don´t want to care about DTML to publish their documents using Composer or similar WYSIWYG tools. These documents should be rendered with some standard HTML-code (navigation and the like). Is there any possibility to do this without having to teach everyone <dtml-var> etc.? We tested various things (access rules) but in the best case we end up with nested <html> tags. Unfortunately, we have no python experts here and we´re not learning fast enough to present a solution within time. Some background info: we have to ensure that virtually erveryone here has a simple way to put information on the net. Most of these people have little or no HTML knowledge but use Composer, HotMetal or even word to create their documents. So it seems unacceptable to our bosses to bother anyone with manipulating sources. We would really like to use Zope because of its great management features, user management and expandibility (and its price ;-), so any hints would be highly appreciated.

I can't view my Zope server without authenticating, despite checking the "Access contents information", "View" and "View management screens" permissions for Anonymous in my root folder's security tab, plus making sure that Acquire Permission Settings is checked for all DTML methods referred to by my index_html method. My traceback on the access denied is: File C:\PROGRA~1\Zope\lib\python\DocumentTemplate\DT_In.py, line 682, in renderwob (Object: PARENTS[0].objectValues(['Folder'])) Unauthorized: 0 Anyone? I'm kinda lost on this one.

Can anyone tell me why this might be happening????? I'm really starting to think ZClasses are just a complete waste of time.

Security + XMLRPC
by chas 13 Oct '99

13 Oct '99

Using Zope for B2B. Partner websites take orders from their staff or clientel and relay those orders to us. So, the actual communications between these participating companies' servers and our own server are totally automated. Security exists at 3 layers : a) Host/IP - we've already filtered hosts that can connect to us based on IP. But, since IPs can be spoofed, we may buy hardware VPN solutions. (problem : hardware vpn can be expensive for our partners or even impossible if they are colocating) b) Protocol. At the moment I've got a prototype running with XMLRPC which was damned easy to create. However, there is no security mechanism built into XMLRPC (or at not that I can see). So, all data is transfered in the clear. c) The data/information itself. Since there is no authentication with XMLRPC, the data itself is encoded (using rotor and other simple python encryption modules) with a unique key that we will provide to each participating company/site. I really like using XMLRPC but is the above simply a disaster waiting to happen ? Would CORBA, HTTPS (ie using SSLeay), or SSH be better suited ? And is anyone already doing anything like this ? Thanks in advance, chas

How to stuff a tree from a SQL query?
by Steen Suder 13 Oct '99

13 Oct '99

As posted the other day, I'd like to create a (multilevel) tree from the results of a SQL query. With insightful input from Hannu, I've simplified my db design to something more useful. I have, among other fields, a node_id and a parent_id. This should be sufficient to create a tree of "one way linked lists" as I remember them from class. Now my question is: How do I stuff the results from the SQL query into the tree? Stuffing files and folders into a tree is no problem. -- Best regards / Mvh., Steen Suder Linux Systems Administrator Use "sfs @T sciatl DOD dk" for email

Unauthorized problem
by Gilles lavaux 13 Oct '99

13 Oct '99

(Sorry, I send this also to zope-dev by mistake.) Hello, Moving stuffs from zope1 to zope2 I got an unauthorized problem: I do a search with the ZopeFind method in folder where I have a lot of rights. I use a 'formatResult' method with the code bellow. The problem appear when I try to acess properties (the title) of the documents I found. If I am manager it works. giving ALL possible rights to my user doesn't solve the problem. I try to read the document properties (title) with a <dtml-with "sequence-key"> <dtml-var title> </dtml-with> yesterday I had problem using images inside the 'tree' tag, today problem accessing object properties inside the 'with' tag. Is there more problems/rules with the tags in zope2 than in zope1 or is it just me? The code from my findFormat is bellow, thanks for any info:  Search result from :  <blockquote>   Found  candidate(s)        <a href="/ShowDoc?doc_id=&curr_dir=&REFRESH=YES&VIEW=DOC"> </a>  <a href="/"> </a>  TEST:  THIS IS THE PROBLEM:    ''  etc....
