Selection
by Rogerio Atem de Carvalho 21 Jun '00

Hi, I am using sql to fill a selection, following a How-To. When I try to pass the selection plus some text parameters to a sql method, Zope gives me an error. Aparently, the selectioned value is not being passed as a value to the sql. How can I pass the selectioned value as a parameter?

Probably a small bug in ZDiscussion. I have had something similar in ZTopic. You should have gotten a traceback. Its bottom line tells you in what file and what line the NameError occured. Look there, why "r" is not defined. It is probable that in some exception case an assignment to "r" is missing. It probably is available in the non exceptional case. See whether this assignment could be used in the exception case, too, or whether "r" can be initialized to a default value (None or '').

Could you please switch off, "multipart/alternative" text/html message sending to this list.

Newbie Question (dropdown menu)
by joel grimes 21 Jun '00

I'm trying to fill a combo-box (pardon the vb-centric lingo - I don't know what the things are called - it's a <select...><option...> thing) with items selected from a table. I haven't a clue how to do this. I've got the ODBC Connection and SQL Method working, but how do I iterate through the query results to fill a drop-down?

Re: [Zope] Change Notification

I may be confused, but normally the object should _know_ that it has been modified, because one of its methods has been called. In fact, the usual pattern for this is to have the object notify other interested parties ("Observers") of the fact that it has changed. 2.2 has experimental support for this -- see $ZOPE/lib/python/OFS/DefaultObservable.py. Also, see the writeup on this in the Intefaces wiki (start from http://www.zope.org/WikiCentral -- look for ObserverAndNotification. Tres.

Probably a simple name space question
by Bert Jan Bakker 21 Jun '00

21 Jun '00

Hi all, I'm struggling with a problem in DTML for a day now and I'm ready to beg for someone to enlighten me. Problem: I want to call a Z SQL Method (say InsertFoo) from a DTML Method (say CallingInsertFoo) and it just won't work. The Z SQL Method takes three arguments, let's call them a_id, b_id and c_id. All three arguments are available to me in the calling DTML Method. I can print them in HTML. But when I call the query with <dtml-var InsertFoo> I get the following error: "Error Type: Bad Request Error Value: ['a_id', 'b_id', 'c_id']" I tried all sorts of things but I'm thinking I am missing something obvious. What am I doing wrong??? Greetings, BertJan Bakker

Local File System (LocalFS) install problems
by J. Atwood 21 Jun '00

21 Jun '00

(I have searched the newsgroups and zope.org) I downloaded and installed LocalFS (untar in zope dir) restarted Zope (2.1.6 on Linux running as Nobody). The Local File System is an available object but when I try to add it to any folder I get..

External Method Difficulties
by Jason Lee 21 Jun '00

21 Jun '00

For background purposes, I need to write a python module that will generate an MD5 hash of a given string, and return the base 64 representation of that hash. The problem I am facing is getting my stub to work from my DTML document. What I have write now is a stub that takes no arguments and returns "Hello, World". When I click Try It from the management screen, it works fine, but I can't seem to make it work from the DTML doc. This is what Iv'e tried (I'm still pretty new so I'm making wild guesses :) <dtml-call genhash> This produces nothing. I think I read somewhere that dtml-call returns no data, so that might explain it. I could be wrong. <dtml-var genhash> This produces a KeyError. It seems like I've tried a couple of other manglings, but what they were escapes me for the moment. I'm not passing a parameter right now, cuz I wanted to simplify things once I found out it wasn't going to work like I expected it to. What am I doing wrong? Is there a better place to start than this list? I have the content manager's guide and the dtml reference, but I can't find anything helpful. The ID for the external method is md5 in case that helps. Thanks a lot! -- Jason Lee - Programmer/Analyst The Fox and the Grapes: I'm not sure what the point is here.

RE: [Zope] ZServer+SiteAccess+Apache+SSL
by T.J. Mannos 21 Jun '00

21 Jun '00

I got Apache+mod_ssl+OpenSSL working, and I just threw it into the mix. I have two virtual hosts, one HTTP on port 80 and one SSL on port 443. Both do nothing but ProxyPass to the same http:// address on port 9080. I don't know if I like that solution, though. This solution "looks" secure, but I'm not so sure. It's a secure connection between the client and the server, and, since Zope and Apache are on the same machine, there's no insecure communication over our LAN. However, if I happen to have a hacker running a packet sniffer on my server, I'm screwed. Any comments on this? I may just have to go the hard way and do Apache+fastcgi...? --- In zope(a)egroups.com, Wayne Izatt <wayne.izatt@m...> wrote: > I've just managed to get ZServer running behind Apache with SiteAccess > (thanks for the how-to, anser!) > > Now, has anyone managed to configure SSL into a mix like this?
