Well, I want to store several versions of each image. Let's take a simplified case where I want the original image and a thumbnail, both of which need to appear as subobjects of the ZClass with the meta-data. If I store all the RackImages (originals and thumbnails) in one Rack, how do I differentiate between them, so that '/Archive/001/thumbnail' and 'Archive/001/original' show the appropriate images? It just seemed simpler to create a 'thumbnail' Rack and an 'original' Rack. > >I realize that I need to tie the Racks together in the > >specialist using SkinScripts > > SkinScript doesn't do anything to tie racks together or to a Specialist - > it's just a way of describing where the data comes from/goes to for a > particular Rack. That's what I meant, sorry. The RackImages need to appear to be attributes of the ZClass, and I'll use SkinScripts to accomplish that. > >Where do I put the separate Racks? do I create a specialist > >for each Rack (seems unneccessary) or do I put several Racks > >in the same Specialist? > > Several in the same, if they are providing objects which fill the same role > in your overall application.

That works (Duh). Michael Bernstein.

Homegrown vs. Storebought
by Edmund Goppelt 03 Apr '01

03 Apr '01

I'd like to add two capabilities to my city government web site: 1. users should be able to initiate discussions about legislation pending before our City Council. i.e., discussions will be tied to the relevant bill document. 2. users must register in order to post. I'd like enough information so that if someone posts death threats or the like they can be tracked down. I don't need threaded discussions (though that would be nice) so I'm tempted just to roll my own. Is there anything out there in the way of easy to use discussion Products that I could pop in to my site without buying into a gigantic set of associated machinery a la CMF? As far as enforcing some minimal accountability on the part of posters, the Membership product seems like my best bet, though there are some things I'd like to change, e.g., I'd like user info stored in a SQL db, not Zope, passwords should not be encrypted 'cause I want to send them out every month, and I want different info. stored about users than the default properties provided by the Product. How hard do you think this would be with Membership? Are there any other Products I should consider IYO? Thanks! -- Ed Goppelt

Optimizing Zope
by Stefan Bambach 03 Apr '01

03 Apr '01

Hello, Running Zope 2.2.2 on Dual PIII 933 with 1GB of RAM. This machine is not fast enough to handle my requests (about 800 Users using this system). It's a very complex document managing system with about 5000 documents actually and growing every day. Search requests are with Python backend. The backend sends lists of objects with methods and data. I print the data in DTML sequences calling the objects methods. System is a 2 server system, which do the data syncing over xmlrpc. One system is a Windows NT and the other is Linux. The high load results on Windows NT in Dr. Watson system crashes and on Linux only zope goes down. Windows NT crashes very often (about every hour), while Linux is crashing every few month. 1.) I tried to optimize it with simple objects, that only have the data in it and then print it with DTML (<dtml-var "variablename">). This is faster, because of the simpler objects. 2.) I tried running zope with apache's cgi, fastcgi over sockets, fastcgi over TCP/IP. Result: Slower than only Zope. 3.) Is there a way of avoiding error 'competing conflicts' in the internal Zope Classes ? This crashes the NT box very often. So the admin have to restart the service all the time :-( And it is not sure that it comes up again. Sometimes a reboot is the only way. Any Idea ? It doesn't matter how stupid it sounds. ciao.

webdav GET method
by Terry Kerr 03 Apr '01

03 Apr '01

Hi, I find webdav useless in editing zope content as GETting a DTMLMethod for example, returns the processed method rather than the source. This is expected since webdav extensions to HTTP do not redefine the HTTP GET method, hence a webdav GET is simply a HTTP GET. I had a quick search of the zope-dev archives and some webdav resource, but surprisingly didn't find an discussion on this problem. What are peoples thoughts on this? Am I missing something? terry -- Terry Kerr (terry(a)adroit.net) Adroit Internet Solutions (www.adroit.net) Phone: +61 3 9563 4461 Fax: +61 3 9563 3856 ICQ: 79303381

SkinScript Questions
by Michael R. Bernstein 03 Apr '01

03 Apr '01

Hi all, I had some questions about SkinScripts: 1) Are there any naming conventions for SkinScripts? 2) Is there any reason (other than factoring) to split SkinScripts up, or is putting all your declarations in one SkinScript ok? Thanks, Michael Bernstein.

Zope 2.3.1-compatible ZEO Release
by Chris McDonough 02 Apr '01

02 Apr '01

There has been a new ZEO (Zope Enterprise Object) release, primarily made to achieve compatibility with code in Zope 2.3.1. If you are running ZEO, you need upgrade to ZEO release 0.5.0 before you can use Zope 2.3.1 reliably. The new release also fixes bugs found in previous releases, and can be used with Zopes prior to 2.3.1. For more information, see http://www.zope.org/Products/ZEO.

Can't _setObject???
by Lalo Martins 02 Apr '01

02 Apr '01

Hi there I just found out (while coding ZUnit 0.2) that ZUnit 0.1 doesn't work on Zope 2.3.x for some reason. The method manage_startTests of the TestRunner class creates an instance of TestResults, runs the tests with it (using RESPONSE.write(), if this makes a difference), then adds it to itself using self._setObject(). On Zope 2.2.x this works like a charm. On 2.3.x it doesn't bomb, doesn't raise an exception and doesn't set my house on fire, but the TestResults object simply isn't persisted. We tried all kinds of desperate things, like setting _p_changed on both TestRunner and TestResults, and doing a get_transaction().commit() - nothing changes. Out of curiosity, we enabled the addlist in TestRunner and sure enough, you can add objects via the addlist and they persist normally. Anyone has a clue? Of all things that changed between 2.2 and 2.3, which one can be killing us like that?
