Adam, You've posted this question to the zope-dev(a)zope.org list. This mailing list is about the technical internals of Zope, and developing new Zope products. Your question is more to do with using Zope as a web developer. You're more likely to get a useful response to your question if you post it to the zope(a)zope.org mailing list. I've cc-ed this message to that list instead of the zope-dev list. Also, please send messages to the zope mailing lists in plain text, not as HTML mail messages. Some folk find them difficult to read, and you won't get the benefit of their answering your queries. As for your query, I'm not exactly sure what you want to do, but perhaps the Zope Style Sheets product would help. http://www.zope.org/Members/haqa/ZStyleSheet_news You can also make dtml methods return dictionaries by including a line like the following: <dtml-return "{'foo':'value for foo', 'bar':'value for bar'}"> You can use the following how-to to learn how to create random content. http://www.zope.org/Documentation/How-To/RandomContent I hope that helps. > Adam Pawliuk wrote: > > Hi, > > I want to find an efficient way of adding a dictionary of values to > the Zope namespace, where a different dictionary could be set on each > request. > > I wanted to create a several dictionaries each containing properties > for a look and feel (i.e. background colors, fonts etc), and switch > them for each request. > > For example I'd like to do something similar to what's done below > (although the method below doesn't work). > **************************************************************************************** > <dtml-call "REQUEST.set('LookAndFeel',m_getRandomLookAndFeel())"> > > (assuming the Look and Feel Dictionary has key's LOOK_COLOR, and > LOOK_FACE) > > <dtml-with LookAndFeel> > <font color="<dtml-var LOOK_COLOR>" face="<dtml-var LOOK_FACE>"> > I know the with doesn't work for the dictionary, but would like > to do something similar to this example. > </font> > </dtml-with> > **************************************************************************************** > > thanks in advance, > > Adam -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Have you looked in the mailing list archives? Perhaps your question has already been answered there? Here's a link to a searchable archive. http://zope.nipltd.com/public/lists/zope-archive.nsf/ I searched just now for "request and frames", and there were a number of helpful-looking results. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

www.zope.org after upgrade
by Aleksander Salwa 15 Jul '00

15 Jul '00

I see there are some problems with this site after migrating to 2.2.0 I just wanted to download ZQR from "Documentation", and I got login/passwd prompt, and then, of course "Unauthorized" error. Don't you think new security model in 2.2.0 is a little bit too strong ? ;))) Let someone fix it, please. ololo

zope crawls - the day after
by Bak ＠ kedai 15 Jul '00

hi all zope is faster now. i think i know why, just wanted some confirmation from the zopistas. setup: apache in front of zope on a rh 6.1 linux what happened: -got a lot of simultaneous connect in one time. whe the number of connect exceeds 200, zope started slowing down. and i mean really slow. -tried putting squid in front, still not much improvement. -set up cache headers again. i did this earlier on, but was not successful. now: -got less then 100 simultaneous connect. zope runs beautifully. what i think that solved this: -setting the cache headers. at first, i put the headers in standard_html_header, before any html documents. later, i put it after <head><title> tags. and i think i can see the cache headers on. HTTP/1.1 200 OK Date: Tue, 11 Jul 2000 09:15:33 GMT Server: Apache/1.3.12 (Unix) (Red Hat/Linux) mod_fastcgi/2.2.4 (mod_pcgi2/1.0.1; PCGI/2.0a5) PHP/3.0.12 Cache-Control: must-revalidate,max-age=120 Expires: Tue, 11 Jul 2000 09:17:06 GMT X-Powered-By: Zope (www.zope.org) Python (www.python.org) Content-Length: 14508 Last-Modified: Mon, 10 Jul 2000 16:24:22 GMT Content-Type: text/html so, i guess, it does matter where you put the cache headers. is there a limit on how many simultaneous connect zope can handle? apache ( i know it's different) can handle much higher traffic with not much complaints. so, correct me if i'm wrong here guys! thanks -- ------------------------------------------------------ http://www.kedai.com.my/kk Am I Evil?

I have a question on Zope 2.2
by Jonathan Desp 15 Jul '00

15 Jul '00

Hi everybody, I'm using Zope 2.2 on my local machine, where I constructed my data.fs, then after I uploaded this data.fs on my hurrah.com server which use an older version of Zope(2.1.6), then I was not able to add any DTML Document or DTML Method, and all the DTML images was broken, as well as at my web site all the pages was "not found" even if I was able to edit those file in the Zope management intereface. Anyone here know how to fix that ? If I cannot upgrade my zope on the hurrah.com server, how I can make the data.fs compatible with the older version.. ?

Announcing dev.zope.org
by Brian Lloyd 14 Jul '00

14 Jul '00

Hello all, For some time now, it has been a goal of ours to open up the Zope development process. Some of you may have heard me promise this at the Zope track back in January. Well, it took a little longer than I had hoped it would, but I'm happy to announce an important step in making that a reality: http://dev.zope.org. dev.zope.org is the place for discovering, initiating, and contributing to work on the core Zope platform and related Zope technologies. You can think of it as the rough equivalent of what Mozilla.org is to Mozilla. Why has it taken so long? Because there is much more to "opening the development process" than simply doling out CVS access. Evolving a relatively large and complex piece of software like Zope is a non-trivial task, and doing it in a highly distributed environment is harder still. The dev.zope.org site will provide the background materials and tools to ensure that work on Zope is consistent in organization and execution. It will also help those new to Zope development to come up to speed and get involved quickly. There is still plenty to do be done on the site, but it is done enough to start using it so I want to start learning by doing. If you have questions or comments on the dev site, please send them to me at brian(a)digicool.com and CC the zope-dev list (which is where I expect traffic related to dev.zope.org should go in the near term).

Class Refactoring Question
by James W. Howe 14 Jul '00

14 Jul '00

I've developed a couple of simply Python classes which I'm using as base classes for some ZClasses that I've developed. I now realize that both of these Python classes could benefit from obtaining behavior from another class. Will I complete hose myself if I change the class definition of my Python base classes? In other words, will existing ZClass instances be completely screwed up if I do this? For example, suppose that I have a base class written in Python which looks like this: class MyFolder(OFS.Folder.Folder): ... I have a ZClass which uses MyFolder as a base, and I have one or more instances of my ZClass in my ZODB. I would like to change the definition of MyFolder to be something like this: class MyFolder(OFS.Folder.Folder, SomeOtherClass): ... Can I do this, or am I asking for trouble. Thanks. James W.

Accessing the Application (or Control_Panel)
by Jeff K. Hoffman 14 Jul '00

14 Jul '00

Hello, I am working on a Python Product (subclass of ObjectManager) that creates some instances of a few ZClasses inside itself when constructed. Currently, I do this as follows: CONTROL_PANEL = None def manage_addMyClass(self, id, title='', REQUEST=None): global CONTROL_PANEL if CONTROL_PANEL is None: CONTROL_PANEL = self.Control_Panel self._setObject(id, MyClass(id, title)) ... class MyClass(...): def __init__(self, id, title=''): self.id = id self.title = title ob = CONTROL_PANEL.Products.MyProduct.MyClass('myId') ob.id = 'myId' self._setObject('myId', ob) which works fine, until I need to use CONTROL_PANEL from somewhere else before manage_addMyClass is called (currently, I am trying to upgrade existing instances in __setstate__). Inside __setstate__, self.Control_Panel throws an exception, for understandable reasons. So, I get the feeling I am going about this incorrectly. I grep'd the source last night, looking for a getApplicationInstance() method, or something similar, but found nothing. AFAICT, there is no easy way to get ahold of the one true Application object without having a reference to an object in the ZODB and calling getPhysicalRoot(). Did I miss something? Is there a better way to do what I am trying to do? --Jeff --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff.hoffman@goingv.com Going Virtual, L.L.C. http://www.goingv.com/

I consider myself a ZOPE newbie, because use I use ZOPE to access some really simple databases. I have NOT done any special python programming (but not for lack of trying) but would like some input on what I should say about ZOPE. 1) Is there a ZOPE demo for that runs on a CDROM? I think you're looking for the "Zope on CDROM howto": http://www.zope.org/Members/jens/news/zope_on_cdrom > 2) What is the best way to present ZOPE? Hm. In a bed of lettuce with an olive on top?
