Hi! We have two server, a development-server and a "official-server" where the website are stored. On the development-server is ZOPE installed and on the "official-server" not. Is there any possibility, to produce the dynamic website statically. So that, I can transfer the website as normal .html pages on the "official-server". Thanks. Matthias Füsting

Sorting XML nodes?
by Jean Jordaan 31 Jul '00

31 Jul '00

Hi Zopers (and Lex), >From the (excellent) 'How-To: XMLDocument Example' (Created by eukreign. Last modified on 2000/06/06) I get the following to display all the nodes of an XML document: <dtml-in "contacts[0].getElementsByTagName('contact')"> <tr> <td> <dtml-var "text_content('firstname')"> <dtml-var "text_content('lastname')"></td> <td> <dtml-var "text_content('extension')"></td> <td> <a href="<dtml-var "absolute_url()">/edit">edit</a></td> <td> <a href="<dtml-var "absolute_url()">/delete">delete</a></td> </tr> </dtml-in> I want something along the lines of: <dtml-in "contacts[0].getElementsByTagName('contact')" sort="lastname"> Is such a thing possible? Thanks! -- jean

RE: [Zope] zope.org down

The InterbaseStorage product is full-featured (undo, versioning). But I've gotten little response to releasing it, and I don't think anyone is using it, so bugs are sure to exist. > -----Original Message----- > From: ethan mindlace fremen [mailto:mindlace@digicool.com] > Sent: Monday, July 24, 2000 11:11 AM > To: Cary O'Brien; zope(a)zope.org > Subject: Re: [Zope] zope.org down > > > Cary O'Brien wrote: > > > Hold on.

Can't create ZClass under 2.2.0
by Tony McDonald 31 Jul '00

31 Jul '00

Hi all, I've got the Beehive tutorial on Zclasses and thought I'd try it out on a 2.2.0 system we have here. I have 'create constructor types' and 'nclude standard Zope persistent object base classes? ' set. I've tried selecting various Base Classes (and no base classes), but get the following traceback.   </body> </html>  Thing is, I've deleted the ZDiscussions and ZBase products as well as packing the database - these products shouldn't be there....

How can I proxy from apache to zope and keep source host info?
by Marcin Kasperski 31 Jul '00

31 Jul '00

I configure 'apache as frontent do zope'. Most things work as expected but I found serious limitation: if I pass request from apache to zope via mod_proxy (or mod_rewrite [P]), zope sees all requests as coming from localhost (I specified http://localhost:8080/ as zope address, in case I specify http://my.host:8080 I would get my.host as source address - the problem would be the same). Does there exist any solution to this problem different than using zope.cgi? -- Marcin.Kasperski | Communication takes place between people, documents @softax.com.pl | are secondary.

31 Jul '00

What DTML-VAR do they use on Zope.org to populate the came_from variable for the 'login' link? I have used dtml-var absulute_url but it does not seem to return the full path 'http://www.thedomain.com/folder/page.html' Any help would be great. Thanks, J

Unique id product

Do you need unique sequential ids, or will just unique ids do? The problem with sequential ids is that you need to store the next id in the sequence somewhere, and access to and incrementing this value becomes a performance bottleneck for your server. Also, if you store the sequence value in the ZODB, you will be creating an undo record each time the id is incremented, and this is an additional performance and storage overhead. If you just want ids that are unique to a folder, try the following algorithm (taken originally from the Discussion object code in the PTK). The variable "self" is the one passed to the constructor method of a particular Python class, and represents the folder you want to put the new object into. I'm assuming the object is a "FooBar Item". The "foobar-%06d" bit generates a unique id for the object that looks like "foobar-290172837", based on the current time. id = int(DateTime().timeTime()) while hasattr(self, str(id)): id = id +1 id = 'foobar-%09d' % id The advantage of this approach is that there is very little contention in most cases. > Is that zodb automatically serial all transaction? For the purposes of generating ids, yes. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
