automatically doing a Catalog search as part of object traversal...
by Anthony Baxter 30 Nov '99

30 Nov '99

Say I have a catalog HelpCatalog, with a bunch of documents that have unique IDs. I want to be able to do something like HelpCatalog/by-id/SomeUniqueID and have it return the document SomeUniqueID. Do Catalogs support any sort of Direct Traversal like this? Or am I going to have to do it myself with a mixin class? Thanks, Anthony

copy&past question about zdiscussions
by sdf 30 Nov '99

30 Nov '99

I found that the ZDiscussions componet can't be copy&paste with ZDItems in it,because the ZDItem is not a addable object out of the ZDtopic. I manage to pull the ZDItem out of the ZDTopic,and the ZDTopic can work well as before.but when I add a ZDItem in a Folder,the system reports an error,anyone else notice the problem?

Bill, there should be an executable in your Zope machine's $SYBASE/bin directory named "dsedit". Run it and add the 11.0.3 server to the list of machines. This adds a line to the $SYBASE/interfaces file that will allow you to connect. Chris McDonough Digital Creations, Inc.

Sybase DAv2 connection problems.
by Bill Anderson 29 Nov '99

29 Nov '99

OK, I have it working when connecting to my local 11.9.2 server. Works great. Unfortunately, when I try to connect to the 11.0.3 server, it fails, giving me 'invalid connection string'. I would figure that connecting would be backwars-compatible, am I wrong? Could it be a port issue? 11.9.2 runs default on 4100, but it appears 11.0.x (at least here) is running on 4002. Looking in the source, but so far, no great luck :-( (yes, I am at work again, please cc me if possible) (Of course, if they decide to get the Support Contract, I may just put this address on the list as well :-) -- Bill Anderson Linux/Unix Administrator, Security Analyst ESBU (ARC) bill_anderson(a)boi.hp.com My opinions are just that; _my_ opinions.

ZServer HTTP 1.0 persistent conections (was [Zope] Netscape/Zope cache problem) problem)

This code from ZServer/medua/http_client.py seems to imply that it should be persistent (only there's a bug somewhere preventing it): connection = string.lower (get_header (CONNECTION, self.header)) close_it = 0 wrap_in_chunking = 0 if self.version == '1.0': if connection == 'keep-alive': if not self.has_key ('Content-Length'): close_it = 1 else: self['Connection'] = 'Keep-Alive' else: close_it = 1 -- Itamar S.T. itamars(a)ibm.net

Brian and I talked a bit about this and we don't think this should be provided to DTML, it could mess up assumptions about calling an 'abort' and then things happening after that, in it's current state zope might try to commit changes after you've called abort since it never expect application level logic to be called after the commit or abort point. I believe it works on the assumption that transactions are only rolled back on errors. Why not standard_html_error? You can catch any number of your own errors that you raise in your code with a <dtml-if> construct, just test the value of error_type and then call specific pages based on those errors. Note, it's not a good idea to call documents from an error handler that can raise errors! You have to be careful about that. -Michel

Using recursion with a SQL method
by Jim Cain 29 Nov '99

29 Nov '99

All, I have a MySQL table "category" with the following schema: id number name char parent_id number The table is self-referencing in that the parent_id points back to an ID. This structure renders a hierarchical listing of categories, with the root categories having a parent_id of -1. I have a SQL method to select category names and IDs by their parent ID: ID: Query_category_by_parid Arguments: parent_id:required:int Query: select id, name from category where <dtml-sqltest parent_id type=int> order by name I have a DTML method which calls itself recursively to find a list of categories starting with the specified parent: ID: list_categories <dtml-in "Query_category_by_parid(parent_id=parent_id)"> <p><dtml-var name> (<dtml-var id>)</p> <dtml-var "list_categories(parent_id=id)"> </dtml-in> This however, doesn't work. It appears that the second call to Query_category_by_parid, within the second call to list_categories, fails. Here is the URL: /list_categories?parent_id=-1 This is the error I receive: Error Type: NameError Error Value: Query_category_by_parid And here is the traceback: Traceback (innermost last): File /usr/local/src/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/src/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/src/Zope-2.0.1/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/src/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/src/Zope-2.0.1/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: list_categories) File /usr/local/src/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: list_categories) File /usr/local/src/Zope-2.0.1/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: list_categories) File /usr/local/src/Zope-2.0.1/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: list_categories) File /usr/local/src/Zope-2.0.1/lib/python/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: Query_category_by_coid_parid(parent_id=parent_id)) File /usr/local/src/Zope-2.0.1/lib/python/DocumentTemplate/DT_Util.py, line 321, in eval (Object: list_categories(parent_id=id)) File <string>, line 0, in ?

I've backed off the patch for now and asked Phillip to send me one as a file att. so that even _I_ can't mess it up :) Could those of you who use CVS try updating your FCGIServer.py to verify that it works again and let me know? Once I get the patch back from Phillip I'll probably need a volunteer or two to try it out on their (non-IRIX) sites before checking it in again... Thanks!
