However, I may also be a Zope feature. When you access an unprotected object, Zope may not determine the "true" authenticated user but simply return the anonymous user object. This is nasty, if user objects have additional properties or additional roles that are inspected in an unprotected page. Dieter

The tree tag itself does not cache. You could implement your own cache in your external methods. We extended the tree tag with a "has_branches" argument. If present, it should be a method that tells for the current object whether it has branches (aka children). This reduced the number of database accesses (where our tree data really lives) by an order of magnitude. In principle, I could give you (or the community) a patch for "has_branches". Unfortunately, we extended the tree tag quite drastically (configurable icons, "has_branches", "input type=image" instead of "a href" tags for tree operations). Thus, the "has_branches" extension comes embedded in a big patch that may not be easy to understand. Dieter

The "why" is only my guess: support for the widespread idiom "<dict>.items()", "objectItems" etc. Form the DTML reference: sequence-key The key associated with the element in an items sequence. An items sequence is a sequence of value pairs that represent a mapping from a key to a value. Dieter

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.

This sounds like a good idea, IMHO. The Zope Book doesn't go into much detail about technologies outside Zope.
