Netscape wants to download an index_html doc
by Graham Chiu 14 Jun '99

14 Jun '99

Occasionally I find that Netscape wants to download a document rather than display it as it should. It doesn't seem to happen with IE5. It's happening a lot more with the Squishdot product as well. Is this a Zserver problem? Is there a way I can look at the headers before they hit the browser to see what's happening? Using NT4, and 1.11pr1. ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz

Property sheet inheritance for Z Classes
by Alexander Staubo 14 Jun '99

14 Jun '99

Possible suggestion for improvement: When creating Z Classes that use inheritance, sometimes you'd just like to extend a property sheet from the base class(es), rather than implementing a lowest-common-denominator sheet at the base-class level. Is there a way of doing selective or accumulated inheritance on property sheets, or can it be implemented? For example, a descendant class might to inherit properties "title" and "author", hide the inherited property "keywords", add add the property "subject". Visibility modification might not be easily doable or even desirable (haven't thought that one through yet), but the lack of inheritance seems like a serious omission to me. Right now, if I want to specialize a Z class by adding just a single property to a descendant, I must create a new property sheet and add it as a view. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

offtopic: xemacs and zope.
by Anthony Baxter 14 Jun '99

14 Jun '99

Hi there folks, for those of you using xemacs and zope, what's the magic needed? I've downloaded xemacs 21.1, and the latest huge tarball of packages. When I try to login to the management screen, I'm asked for username and password, then it bombs with 'symbol's value is null: base64-encode-string' or some such. It looks like something's not installed properly, but what? not an emacs user, Anthony.

using a SQL server

Hi all, Which is the recommended way to use a SQL database from a product (use Z SQL methods or directly the database connection ?). -- If you understand what you're doing, you're not learning anything.

RE: [Zope] Software for Zope
by Alexander Staubo 13 Jun '99

13 Jun '99

I second the idea! The contribution page right now is pretty tight -- a first-time user will have no idea, for example, what "TinyTables" is by looking at the page. Reorganizing the software part of zope.org better would not only be functional, but also serve as a nice example of a dynamic Zope-built web section. And why not mix supported and unsupported software? It would be cool if most Zope tools and products -- including database adapters and components -- could be put in the same hierarchy. Moreover you should permit moderated third-party uploads, perhaps with a section called "Incoming", a holding pen for unmoderated, recently uploaded software. I think this section could be nearly autonomous, since moderating the uploads would steal very little of DC's precious time, at least theoretically -- plus, recognized authors could be given privileged access to the database (automatic acceptance of uploads, and ability to maintain own product information). Ties in rather nicely with ZPT, doesn't it? Be Inc.'s BeDepot site (http://www.bedepot.com/) could be a fitting template here, albeit on a smaller scale until the library grows (nay, swells!). -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

RE: [Zope] Name of top level folder
by Alex.Thomas＠dresdnerkb.com 13 Jun '99

13 Jun '99

Next challenge is to be a bit more selective about which documents are displayed in the tree. For instance, could I not include objects with a 'dontIndex' property set by filtering the list that ObjectValues returns? No idea how to code this, probably something to do with map or apply sorta things, if anyone has the answer to hand this should keep me quiet for a bit! thanks a lot alex -----Original Message----- From: Alex.Thomas(a)dresdnerkb.com [mailto:Alex.Thomas@dresdnerkb.com] Sent: 11 June 1999 03:31 To: zope(a)zope.org Subject: RE: [Zope] Name of top level folder Ah, brilliant - the expr keyword comes to the rescue. Many thanks, don't think I would have found that for a long time.

You're right, the root object does not have a name, but that should stop you from including it in iterations, or the tree tag. To tell the #tree tag to start at the top, do:    Note that, for obvious reasons, the top level will not be included in the tree. (If you're wondering how the hierarchical tree seen in the Zope management screens manages to include the root object, this isn't a trick performed just with the #tree tag.

External method writing to a log
by Martin Dougiamas 13 Jun '99

13 Jun '99

I want to create an external method to append to a log file (for almost every access to the Zope site). Obviously opening and closing files this often is going to get a bit silly. Is there a way to keep a file open for the whole time that the Zope server is running? Or do I need to create some completely separate OS-level process that handles the file, and just gets called by the external method? Cheers, Martin -- ### Martin Dougiamas ### ### http://dougiamas.com ### ### martin(a)dougiamas.com ###
