security document comments
by R. David Murray 09 Sep '00

09 Sep '00

Well, I just tried to post several paragraphs to the security interface wiki, and netscape reported a proxy problem. It then ate my posting instead of giving it back to me when I pressed back. So I'm going to try to recreate what I wrote here and hope someone will post it for me or something. (If only w3m supported cookies...) 1) "in an anonymous context" made me think first of anonymous users. I'm really not sure it's a very evocative phrase. It's really about manipulating a reference to the object instance itself rather than calling one of its methods. 2) The doc is great, but I also like 'command reference' type things where you get the complete syntax and semantics for each method. If I can only have one doc, I'll take this one, but I can wish for both <grin>. 3) Although I've written and worked with python Products (and with python itself for longer), I really don't know what "subobjects where the subobject supports the setting of arbitrary attributes" are. How about an example of one of those? 4) Having read this doc, I now understand how the current security model works much better. I think that indicates that this interface is definately a move in the right direction in terms of making the whole thing more understandable and usable. --RDM

RFC: Zope Security for Developers
by Brian Lloyd 08 Sep '00

08 Sep '00

Hi all - There was quite a bit of discussion on the "security assertion spelling proposal" on dev.zope.org recently - it has since turned into an active project and I have a draft of the first deliverable (user documentation) ready for review and comment: http://dev.zope.org/Wikis/DevSite/Projects/DeclarativeSecurity/ZopeSecur ityForDevelopers PLEASE take a few minutes to review this - it will become the official documentation for how Python developers use security very soon! Thanks! Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Render DTML without having it in a Zope object
by Stephan Richter 08 Sep '00

08 Sep '00

Hello everyone, I have some HTML/DTML saved in the database and I want to now display it. But before I display, I need to render the DTML that is contained in the text. Can anyone lead my in the right direction; maybe by telling me which file handles the rendering and I can read some source code. But of course, it would be cool, if I could get a more explained response. BTW, I can call the method to render the text from Python or DTML. I really don't care. Thanks in advance!!!

TIA -Brett Ok, So after some *major* hacking, i've realized that the 'md' passed into the render() method of my dtml tag contains the namespace, and is of type 'TemplateDict' which appears to contain a stack of 'MultiMapping's. Weird. Well, anyways, I just used the 'has_key' and 'getitem' methods to lookup my item. The question now is how do I create a new object in the current namespace? It looks like the TemplateDict is a read-only type of data structure. Anybody? TIA -Brett
