- Zope - Zope lists

Why doesn't this work?

The method below displays a list of documents in the current folder, and is invoked from one of those documents. I want it to show the title of the current document as bold and not as a link, but it always displays as a link. I can display the values of 'thisdoc' and 'id' on each line, and I see what looks like a match, but the else branch is always used. I don't understand. Any hints? Thanks in advance. - Craig    <A HREF="index_html"> In this folder...</A>     <a href=""></a>

More than one Zope site for one Zope installation ?
by lstep＠mail.dotcom.fr 09 May '99

I have several users who want all to have access to Zope. These users have each a domain foo.org, bar.org, but it points to the same machine, with, currently, one standard Zope installation (with PCGI with Apache). They currently use standard Virtual servers functionnality from Apache. Now I'd like to allow them to have a zope access to each of them. As they want http://user.org/ to be their base url, I need to keep the virtual servers. I think my solutions are: Make several copies of the Zope tree, and with each one, make a database, and point the the good zope pcgi in each virutal server. It is not an acceptable solution for me, as having several Zope instances gets a lot of ressources ;-( Make only one Zope tree, with only one database. Create a folder in the database for each user, and make each virtual server map '/' to the user folder. I tried this, but I had big problems caused by the fact that '/' is not /user_folder :-( Is there something possible with ZServer (without Apache)? Is there some "virtual server" implementation (making a database for each user, or all users in the same database)? Some time ago, I saw a thread about a variable "INSTANCE_HOME", what is it about, and is it implemented in V.1.11 ? Thanks, Luc

Note however, that there are subtle differences between using a method by name (no quotes) and calling it in an expression (quotes). I got bit by this just the other day, and I'm still not 100% on the full behavior (I'm sure someone here will correct me if I'm wrong). Lets say you have your Method, and it returns a list:  <li>  Calling it by name the very first time you use it in your DTML Method|Document will cause the results to get cached and bound to the name 'Method'. After DTML rendering engine execute 'Method', it then turns that object into a sequence object (or a mapping if you specified the 'mapping' #in tag attribute). At this point, "Method" is no longer callable. So:       Will raise an exception at the second #in expression. This is nice if 1) Method does not require any arguments, and 2) Method is an computationally expensive procedure (like searching a large external database of some kind). This behavior happens for all callable objects, not just External Methods. Python Methods, ZClass Methods, and others will behave similarly. So the point is, be consistent in your usage of Methods in DTML. If the cacheing behavior breaks something of yours, use the expression syntax (quotes) as expressions are never cached. -Michel > --- Ben Derstine <bend(a)ecollege.com> wrote: > > I have an external method that returns a list call > > List.

possible security enhancement to CookieCutter product
by Mark Hays 09 May '99

09 May '99

I always enjoy Saturdays ;&) Attached are some mods to CookieCutter.py -- my changes start at "MIC stuff". The overall idea is to make it "safe" to stick arbitrary pickled python objects into cookies. And get them back again intact (with verification), of course. Comments/flames welcome, Mark

Iterating over items returned from external methods
by Ben Derstine 08 May '99

08 May '99

I have an external method that returns a list call List. I am using a DTML document to display the results of the method. As it is now Zope simply displays ['Sales', 'Marketing','Research'] However, I would like to be able to display the list by iterating over the list instead of directly displaying the raw list. I know about the DTML 'in' tag to iterate over a sequence. I just can't find any documentation on how to use it for a list returned by an external method. Would anyone have a simple example of this?

Zope 1.11 timeouts with IE 5.0
by Alexander Staubo 08 May '99

08 May '99

I'm having some problems on Zope 1.11 (running ZopeHTTPServer) with IE 5.0 (this is NT, SP4). Pages in the management interface usually load fine, but IE will never load images on first attempt -- they time out. A simple refresh on the individual frame will usually bring up the images. Occasionally single pages time out, as well, or the server gives a "connection refused". I experienced the latter problem with Zope 1.10.2 to a certain extent; with 1.11 it seems to have worsened.

I'd like to mention that Jim has made some additions to the Add ZClass screen that auto-generates a DTML Method Form, DTML Method Constructor, and a factory if you fill in a form element. This will make ZClass creation/instanciation more transparent. These changes will make it into the final 1.11. -Michel
