The ZClass methods are methods that are available to any instance of the ZClass. To use the methods, you need to first add an instance. So, in the management interface for your Zope root, you select "ZCounter" from the add list, and assign it an id (eg "test"). >From the web, you could call the GetCount method of test like so: http://your.site/test/GetCount >From DTML, you could call it like this: <dtml-with test> <dtml-call GetCount> </dtml-with> or <dtml-call "test.GetCount()"> (Warning: I did not specifically test the above... I'm just going on what I've done with my ZClasses) Kevin

Zope version of virtual hosts/includes?
by Hunter Kelly 18 Aug '99

18 Aug '99

Hello, there! We have a bunch of sites that we maintain using various methods, but are looking for a better solution than the ad-hoc things that seem to get thrown together, so I thought I'd take a look at Zope, since I'm a big Python fan. One of the techniques we use is to use virtual hosts to change header/footer information for documents. For example, if you visited http://public/ you'd get a view of the data with the public headers/menus/etc, and http://private/ would give a view with the private headers/menus/images/etc. The actual content of the page is the same, however. This is accomplished using inculdes, like #INCLUDE FILE="/x/TopHTML.inc" Then, the /x directory is mapped to different directories, depending on the virtual host that was used... Is there a straightforward way to accomplish this in Zope? Seems like Acquisition would have some way of doing it, but a quick look through some of the FAQs didn't seem to address this issue. Would the best way to be to set up some kind of content folder that isn't directly visible, and then public/private folders that acquire the content itself from a toplevel folder? Or is there another way entirely? Thanks for any help, Hunter

Actually, the issue is not the logistics of upgrading - that would be fairly easy, in fact - but rather, the time for someone (probably me) to just do it - that also wouldn't be prohibitive, but we have to balance it against how imminent a migration to the new zope2 site might be, and that's not yet determined...

Using Z Classes...
by Donald Holten 18 Aug '99

18 Aug '99

Hi! I've created a Z Class named ZCounter with the following methods: GetCount InitCounter SetExclude It has the usuall add and factory stuff too. I've checked out the documentation, and they say how to make a Z Class object, but how do I use one? They didn't seem to have any examples. How, for instance, would I use the method GetCount that is in the ZCounter? Thanks! Donner

RE: [Zope] editing via ftp
by Alex.Thomas＠dresdnerkb.com 18 Aug '99

FTP with XEmacs: XEmacs has an FTP client called EFS that makes FTP sites look like a local file system. The easiest way to use it is to put an entry like the following in the .netrc file in your local directory: machine my.zope.machine#9221 login myname password mypassword (The number after the # is the FTP port, which will be different from the HTTP port. Up until Zope2b1 the default was 9221, now it is 8021, the standard is 21). To save typing in a long site name, you can get EFS to recognize an abbreviation in the same way as the normal file functions. However, EFS is only normally loaded when needed so it won't spot abbreviations the first time an FTP site is accessed. To avoid this, load EFS on startup by adding this line to your .emacs file: (require 'efs) > -----Original Message----- > From: Tim Wilson [mailto:wilson@chemsun.chem.umn.edu] > Sent: 13 August 1999 15:29 > To: Zope Listserv > Subject: [Zope] editing via ftp > > > Greetings Zopesters, > > I understand that ZServer provides access to your Zope > documents via ftp, > but I don't know how to make that work.

www.zope.org and www.zope.org:18200 both back up
by Ken Manheimer 18 Aug '99

18 Aug '99

Both the zope sites are back in service. (I.e., the current www.zope.org and the one that's running on port 18200.) The problem was an infinite recursion in the error handling of the www.zope.org site - the hole that allows this to happen is fixed in the 1.10.x and later releases, but we're still running 1.9 for the zope site. There's a moral there somewhere. Sigh. Ken klm(a)digicool.com

The keyword part of python keyword arguments are not evaluated, they must be simple names. You may be able to accomplish what you're attempting using a dictionary - something like:  I'm not certain about this - but i do know (partly because python told you:) that you can't give expressions as keywords in keyword arguments...

I'm assuming your lines property is called "availability". Let's make the form variable called "newAvLine". <dtml-call "REQUEST.set('availability', [newAvLine] + availability)"> <dtml-call ""propertysheets.properties.manage_changeProperties(REQUEST)"> This is specifically if you want to add an item to the beginning of the list. I think you'll have to do trickery with slices in order to put something in the middle... (something like <dtml-call "REQUEST.set('availability', availability[0:i] + newAvLine + availability[i:]"> I don't think you can really do any kind of variable assignments in DTML other than REQUEST.set.
