ProxyPass - where ???
by George Osvald 15 Aug '00

15 Aug '00

I'm having trouble configuring ProxyPass on my ISP's server. I tried to follow the instructions in the appropriate HOW-TO's without a success. I think they all assume that the user would have root access. I don't. I have built ZOPE in my user directory. Anyway ProxyPass takes two arguments, a virtual path and a URL. In my case is the virtual path a local path to my user directory or zope install directory ? So if: user directory is located @ /home/virtuals/myaccount/ and zope installation @ /home/virtuals/myaccount/zope my web site is @ www.mydomaine.com.au the server is demon.server.com.au and sub directory in ZOPE with my web site is 'okstudio' (I've used SiteAccess for this) then is this correct? <VirtualHost 123.45.678.9> ServerName www.mydomaine.com.au ProxyPass /home/virtuals/myaccount/ http://demon.server.com.au:8080/okstudio ProxyPassReverse /home/virtuals/myaccount/ http://demon.server.com.au:8080/okstudio </VirtualHost> or maybe: <VirtualHost 123.45.678.9> ServerName www.mydomaine.com.au ProxyPass /home/virtuals/myaccount/zope http://demon.server.com.au:8080/okstudio ProxyPassReverse /home/virtuals/myaccount/zope http://demon.server.com.au:8080/okstudio </VirtualHost> originally when using stuff copied from the HOW-TO I used: <VirtualHost 123.45.678.9> ServerName www.mydomaine.com.au ProxyPass / http://demon.server.com.au:8080/okstudio ProxyPassReverse / http://demon.server.com.au:8080/okstudio </VirtualHost> The result was this error message in my browser: >Proxy Error >The proxy server received an invalid response from an upstream server. >The proxy server could not handle the request GET /. >Reason: Could not connect to remote machine: Connection refused Regards, George OK Studio mail(a)okstudio.com.au

Getting a document's contents
by Joshua Brauer 15 Aug '00

15 Aug '00

There is probably a simple solution that I'm overlooking here.... I have a folder (Parts) that contains dtml documents that are snippets of code. I want to include some of them which I have listed in a variable (select). So I use code like this: <dtml-with parts> <dtml-in select> <dtml-var "_.getitem('sequence-item')"> </dtml-in> </dtml-with> or this <dtml-with parts> <dtml-in select> <dtml-var sequence-item> </dtml-in> </dtml-with> In either case I get the name of sequence-item but I want the contents of sequence-item Josh -- ------------------------------------------------- Joshua Brauer Computer Support Scientist Department of Biochemistry and Molecular Biology Colorado State University Fort Collins, CO 80523 (970) 491-1080/pager: (970) 498-7995, #5837 -------------------------------------------------

Zope bug or my stupidity?
by Peter Hernberg 15 Aug '00

15 Aug '00

...I'm betting on the latter :) The problem in a nutshell is that a dtml method seems to be returning itself (that is, the dtml source of the method), rather than what it ought to be returning. I have two classes, a "Topic" class, derived from ObjectMananger, and a "Story" class. The Topics contain Stories. As you might imagine, I wanted a method that would dig up the most recent stories in a Topic. So I wrote one and put it in the the methods of the Topic class. Done with that, I wanted a method that would decide which of the Stories from each topic to put on the main page. But a weird thing happened. I got errors telling me that my function was returing a string (I was trying to use it in a dtml-in tag). That's odd, I thought, so changed the function to simply spit out the results of the method call with a dtml-var tag. I discovered that it was spitting out the source of my dtml method. Yikes! Aren't all variables supposed to be rendered? Here's the method (named get_storys) in the Topic's methods: <dtml-call "REQUEST.set('stories', [])"> <dtml-in "objectValues('Story')" reverse sort=Date> <dtml-if numStories> <dtml-if "sequence-index < (numStories - 1)"> <dtml-call "stories.append(id)"> </dtml-if> <dtml-else> <dtml-if "sequence-index == 0"> <dtml-call "stories.append(id)"> </dtml-if> </dtml-if> </dtml-in> <dtml-return stories> Here's the method that calls that method: <dtml-in "objectValues('Topic')"> <dtml-with sequence-item> <dtml-var "get_storys"> </dtml-with> </dtml-in> <dtml-with "Economic.ColdFusion"> <dtml-var id> </dtml-with> In case you're wondering, I'm running zope 2.2.0. ===== Peter Hernberg An all-purpose, antibacterial, lemon-scented geek/nerd "If there were a nation of Gods,it would govern itself democratically.

RE: [Zope] [Ann] Another Zope Book

This sounds like a good idea, IMHO. The Zope Book doesn't go into much detail about technologies outside Zope. It sounds like your book would, and this would be a good thing. > -----Original Message----- > From: Dieter Maurer [mailto:dieter@handshake.de] > Sent: Tuesday, August 15, 2000 10:45 AM > To: zope(a)zope.org > Cc: woessner(a)springer.de; frs(a)lysia.de > Subject: [Zope] [Ann] Another Zope Book > > > Dear Zopistas, > > I plan to write another book about Zope: "Building Dynamic WebSites > with Zope". > > The book idea: > > Realize a demanding dynamic WebSite with Zope. > Describe everything that is necessary for this purpose. > > > This will contain: > Concepts: HTTP, HTML, Zope, Databases, JavaScript, ... > Components: catalogs, sessions, topics, news, discussions, > stores, mails, LoginManager, customizers, workflows, ... > Programming: building your own components (ZClasses and > Product API) > > > There will be some overlap with the official Zope book. > However, my book has a different focus: > > I will not be complete about Zope.

ZCatalog Question
by Jeff Sasmor 15 Aug '00

15 Aug '00

I have a product that has three CatalogAware Zclasses. They are indexed by the catalog correctly, but when I look at the catalog's status tab, the number of objects for each index are identical, even though the ZClasses themselves don't all have the same properties. Intuitively, this seems wrong. Or maybe my intuition is wrong. It "makes more sense" to have differing number of objects based on how many of each type of ZClass instance was indexed and what the properties of each one was. Anyone have any enlightenment (or is that Zen...) ? Jeff Sasmor jeff(a)sasmor.com

Hi, Why and how are python tuples (like, this) handled differently (and not in a logical way I can see...) than python lists [like, this]? cheers, Chris
