How to get PARENTS[-1] from within a Python Product
by Ira Hochman 26 Aug '00

26 Aug '00

Hello- How does one retrieve the equivalent of PARENTS[-1] from within a Python Product in Zope? I have tried self.aq_parent.absolute_url() which gets the equivalent of PARENTS[0], but I need to get PARENTS[-1]. I am trying to isolate/preserve the portion of the path that contains cgi/pcgi info, if any (as in "http://yoursite.com/bin-cgi/Zope.pcgi"). Alternate approaches to accomplish the same would also be welcome. -- Ira Hochman go2ira(a)onebox.com - email (617) 598-1014 x5511 - voicemail/fax __________________________________________________ FREE voicemail, email, and fax...all in one place.

Linux and ODBC
by Tony Corrente 26 Aug '00

26 Aug '00

Hello.. I am currently using the openlink ODBC drivers to access Progress DB's on a HPUX System from A Linux Web Server using Apache and PHP4. It Works... The rest of my site has been moved to Zope. Everything I've read states that the Zope DA's for ODBC only run under the Win32... Is anyone working on this ?? or how do I do it from Linux ?? I don't want to install a N(asty)T(hing) server if I can avoid it.. Thank you. Tony Corrente Web Administrator OMC Europe V.O.F. Drongen Belgium .

How to implement a round through the whole web site
by Christian Leutloff 26 Aug '00

26 Aug '00

Hi, I want to add a round to a small Zope based web site. Therefor I would like to add a prev and a next button on each page. So it is possible to start on the first page and then move on to the next one by clicking on the next button. After some clicks on the next button I'm sure to have visited all pages. I want to realize this goal through adding an attribute named sequence (´seq´) to every DTML document that should be reached through the round. The value is a 4 digit number that defines the order in which the pages should appear. Then I've started to implement a method using DTML to generate the hyperlinks for prev/next. The strategy would be to determine the sequence number of the actual document. Afterwards all documents are searched and each id is compared to the actual one. The results should be saved in variables that could be used to set up the links after all documents have been processed. My problem is now how to store the intermediate results in variables. I'm able to define a variable (myseq), but I'm not able to change the value afterwards: <-------- snip <dtml-call "REQUEST.set('myseq', 7L)"> <dtml-if "_.has_key('seq')"> <dtml-call "myseq = seq"> <-- wrong!!! Seq: <dtml-var seq>/ <dtml-else> sequence is missing! </dtml-if> <dtml-var myseq> <-------- snap What is the most efficient way to traverse all DTML documents in a given branch of a Zope server? Today I use something like this: <dtml-in "krawczak.objectItems('Folder')" sort=id> <dtml-in "objectItems('Folder')" sort=id> <dtml-in "objectItems('DTML Document')" sort=id> <br> <dtml-var id>, Properties: <dtml-in "propertyMap()"> <dtml-var "_['sequence-item']['id']">, </dtml-in> </dtml-in> </dtml-in> </dtml-in> Are there better solutions? Do you know of a predefined way to implement the round through the web site? Thank you Christian -- Dipl.-Ing.

ANN: ZUBB (Zope Ultimate Bulletin Board) 0.5.0 Release
by J. Atwood 26 Aug '00

26 Aug '00

I have uploaded the update to ZUBB. Both the changes and readme are linked below. There are a few major presentation and feature changes but It still does not work with Zope 2.2. I will work on that when I have a chance (if anyone would like to help that would be great). http://www.zope.org/Members/BwanaZulia/ZUBB/ http://www.zope.org/Members/BwanaZulia/ZUBB/README http://www.zope.org/Members/BwanaZulia/ZUBB/CHANGES As always the sample / test / development board is http://www.bwanazulia.com/kenya/discussions/test/ I have about 6 of these boards in production environments and things seem to be pretty stable as I work to squash bugs. My major concern for now is to see how many posts it can handle before I have to move to something like the SQL based version (which is still in the basic planning stages and will be a whole new game). Suggestions, comments are welcome. J

ZCatalog - OR'ing on different colums (indices)
by Aleksander Salwa 25 Aug '00

25 Aug '00

Is there any better method of OR'ing on differend indices in quering ZCatalog, then the method described in 'Advanced ZCatalog Searching' How-To: <dtml-let res1="MyCatalog(title=userInput)" res2="MyCatalog(PrincipiaSearchSource=userInput)" res3="MyCatalog(someProperty=userInput)" results= "res1[:_.len(res1)] + res2[:_.len(res2)] + res3[:_.len(res3)]"> <dtml-in results> ... </dtml-in> </dtml-let> This seems to me too expensive - here three searches are made. Is there - or should be added - any support for it in ZCatalog ? Another fault of this method are superfluous repetitions in results - if some catalogued object matches search pattern on more then one index. It seems to me to be common case, when we show to user simple search form with only one input (that is where 'userInput' came from) and 'Go!' button. User don't want to know, that we have our data splited in many properties. But on Zope side it's very good to have it structured in that way - so how to reconcile these things ? ololo(a)zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/

FW: Simple(?) Syntax Question (dtml-in)
by Spicklemire, Jerry 25 Aug '00

25 Aug '00

Actually, there are some extraneous "" in the prior post. Here's a corrected version: <dtml-in valid_prj> <dtml-call "REQUEST.set('val_prj_seq_item', _['sequence-item'][0])"> <OPTION value="&dtml-val_prj_seq_item;"><dtml-var val_prj_seq_item></OPTION> </dtml-in> I also should have mentioned that this approach allows use of the &dtml-x; "entity syntax", within tags..
