How do I prevent this? Do not use Python to write markup. Return a data structure to dtml and use dtml to create the markup (or use zpt). For example - In script scaleSizes(size) : real_size=string.atoi(size)/1280 values={'top':str(100*real_size), 'left':str(150*real_size)} return values In a dtml page or method: <dtml-let sizes="scaleSizes(size)"> <style type='text/css'> .headline { position: absolute; top:<dtml-var "sizes['top']">; left:<dtml-var "sizes['left']">} </style> </dtml-let> In other words, let Python do what it is good at and let dtml or zpt do what it is good at - which is rendering markup. The result is a lot more readable and maintainable. Cheers, Tom P

Authenticated role problems
by Michael S. Fischer 11 Oct '02

11 Oct '02

I have a product which declares a security classification ("View Reservation System") and I've restricted the roles that apply to that classification to Authenticated and Manager. Then, in my code, I have: security = ClassSecurityInfo() security.setDefaultAccess("deny") __roles__ = () security.setPermissionDefault("View Reservation System", ['Authenticated', 'Manager']) ... def getFormErrors(...): ... security.declareProtected('View Reservation System', 'getFormErrors') Now, when I attempt to access the object as an Anonymous user, Zope doesn't prompt me for a user ID and password (as it would if the role were restricted to Manager only) to satisfy the Authenticated role requirements; instead it simply throws an exception. Is this a bug in Zope 2.5.1? -- Michael S. Fischer / michael at dynamine.net / +1 650-533-4684 Lead Hacketeer, Dynamine Consulting, Silicon Valley, CA

Again: help to vhm & apache rewrite problem
by Christian Kasprowicz 10 Oct '02

10 Oct '02

Hi all, I'd really appreciate any help on this: I'm trying to do a virtual host mapping with apache. I've the Rewrite Module working, and trying to do the following(in the .htaccess- file): RewriteEngine On RewriteRule ^/(.*)$ http://127.0.0.1:8080/VirtualHostBase/http/www.mydomain.de:80/Chris/mydo main.de [L,P] Also, I tried without the [L,P]. it just shows the directory index of the webserver- not zope. If I try it with /* ... I get the Zope-Site, but with the full path (./VirtualHostBase/http/...) Can anyone help?!? Thanks, Chris

RE: [Zope] Form parsing question - buttons and operand context

If you put each item in it's own form, you can just use an <input type=hidden> tag I guess... -----Original Message----- From: Michael S.

Hi; I have the following Python Script (*not* External Script): import string size = string.atoi(size)/1280 css = "<style type='text/css'>" css += ".headline { position: absolute; top: " + str(100*size) + "; left: " + str(150*size) + "; font-style: 800 " + str(40*size) + "px futura }" css += ".belowHeadline { position: absolute; top: " + str(150*size) + "; left: " + str(250*size) + "; font-style: italic " + str(25*size) + "px verdana }" css += "</style>" return css It isn't rendering properly because the brackets are being translated into ASCII.

Re: [Zope] unexplained shutdown
by Gilles 10 Oct '02

Hello, If zope stop (not hang) then run it in a way to be able to see the console output. Hopefully you will see what cause the problem. The Z2.log log things when the request is completed, it is useless to track fatal problems. Eventualy run zope behind apache, I had less problem this way.

Zope, CMF, WebDAV +Windows' Network Place and versioning.
by Knut Meidal 10 Oct '02

10 Oct '02

Greetings! I have been playing with Zope and CMF. Scavenged an old HP Workstation, a B132L with PA-RISC processor, little RAM and a small disk(2.1GB). Got Debian Linux installed, along with debs of Zope, Zope-CMF. (PostgreSQL too, in case I ever figure out how to move my data in there. Hints appreciated.) I now have a test-CMF site running. I have created a few folders and users, uploaded a few files, published and played around. I saw that Zope-CMF supported WebDAV. And I saw the light. My great vision was to create a Windows "Network Place" to read/write to Zope directly from Windows. This way, I envisioned, I could have people use familiar tools to save documents to a familiar environment. While at the same time, we could attach some metadata to the items, and use versioning between files, with full accounting on who edited what file, when, and possibly keeping track of several versions of the SAME FILE, in the SAME PLACE using the SAME Filename. It almost works. I can create "Network Places", save documents to the Zope folders. Only thing missing is the ability to have Zope versioning on files created in this manner. Can it be done? Anyone else tried this approach? Experiences? Good? Bad? Do's and DON'Ts? Tips, tricks? PostgreSQL pointers? KnutM
