by Jatwood＠bwanazulia.com 08 Mar '00

I am trying to pick a random element from a SQL Method (list) I got this far: <dtml-var expr="_.whrandom.choice(sqlMethodNamet())"> and get... <r instance at 87183a8> I know I a missing the boat in some way in terms of OO and lists but I find this a bit different than my usual Python programming. Any help would be great. Thanks, JMA

getting object reference from an id string?
by Darran Edmundson 08 Mar '00

08 Mar '00

Say one has an object reference and knows the string id of a child node. From this info, we want an object reference to the named child. I'd like someone to prove me wrong that there is not a one-liner to accomplish this seemingly trivial task. I've had to resort to (off the top of my head) code like: <dtml-in "objectValues(['child meta-type'])"> <dtml-with sequence-item> <dtml-if "id == desired_id"> <dtml-call "REQUEST.set('desired_ref',_['sequence-item'])"> </dtml-if> </dtml-with> </dtml-in> I'm really looking for a solution that doesn't require looping. Since Zope enforces unique id's at a given level, the name should be sufficient to resolve the child object. Darran.

Sort order
by Kiran Jonnalagadda 08 Mar '00

08 Mar '00

I can use "sort_order=reverse" to get a reverse sorted list in ZCatalog. What's the equivalent for dtml-in? sort_order doesn't work and I can't find anything else in the docs. -- Kiran Jonnalagadda http://lunateks.com baby.sh: while true; do echo "^G^G^G^G^G"; sed -e 's/food/poop/'; sync; sync; sleep 15; done

Zopistas, I'd really like to give worldpilot a spin, but the FTP site seems to be AWOL. Could someone be so kind as to drop me a copy or let me know where I could find it? Thanks, -- ethan fremen - mindlace(a)imeme.net good design is as close as I want to get to ideology.

Tree-expand bug!?
by Petr Knapek 08 Mar '00

08 Mar '00

Hi Zopists, I have tried to expand tree and a Zope error has appeared. Below, you can see setting up of expand_all variable together with the beginning of my tree. The collapse_all is working without any problem, the tree collapses when the collapse_all is set up to '1'. The problem is only with the expand_all. Is it Zope bug or something wrong on my side? part of my code <A HREF="<dtml-var URL0>?expand_all=1"><IMG SRC="/p_/pl" ALT="Expand" BORDER="0"> <dtml-tree branches_expr="objectValues(['Folder', 'DTML Document', 'File', 'Image'])" skip_unauthorized=1 sort=is_sort_objects> Zope Error Zope has encountered an error while publishing this resource.

call stored procedure from sql method object
by Chien-pin Wang 08 Mar '00

08 Mar '00

I have installed ZOracleDA to bridge Zope and Oracle 8.0.5 on Linux. How do I call the stored procedures written in Oracle from "Add a SQL Method" interface, especially when there are OUT parameters returned from stored procedures? I have read the DCOracle mini how-to but there seems to be a missing step ahead. Assume the scenario: Oracle Procedure: myProc(para1 IN VARCHAR2, para2 OUT INTEGER, para3 OUT REFCURSOR%TYPE) What should I put in the "Arguments" box and "Query template" box? And how do I retrieve the returned arguments in the following dtml document/methods? Thanks a lot! Chien-pin

Get author name from zope
by Sin Hang Kin 08 Mar '00

08 Mar '00

Can I retrieve the author's name from Zope? Is it always available? I am writing a module to put into the header to generate dublin core rdf record. I would like to retrieve this information automatically. BTW, does anybody have "open source" legal notices and privacy policies (a few samples for web masters to choose) can freely distributable with zope? Rgs, Kent Sin
