Excellent, that put me on the right track! Turns out that PARENTS[0] is what I needed. Once I got that working, I make a separate folder named eventsDb and moved the objects into there, cleaning things up a tad. Now I've got another question. Here's my code snippet: <dtml-in "PARENTS[0].eventsDb.objectValues(['Event'])" sort="when"> <dtml-var View_HTML> <P> </dtml-in> Now, View_HTML is a method of the Event object. I get a nice list from it. However, I've got lots of items. The documentation is clear on how to display groups of them. However, there's a catch: I want to separate the events into previous and upcoming ones. Now, inside the loop, I could compare when to ZopeTime, which would work without separating them into batches. But if I'm using batches, this will be horribly messed up. How can I weed out the ones I don't want *before* I get into the loop?

See http://www.python.org/doc/Comparisons.html - while you may have some questions about comparisons hosted at the python site, the first one in the perl/python section is by tom christiansen - that should be reassuring.-) For a pretty incisive description of the relative strengths you should check the comparison essay by Guido van Rossum, python's author, linked in at the top of the comparisons page. It has a small section on python vis a vis perl. > Now, I'm not trying to engage in any language wars or anything, but I was > wondering if anybody might know of a matrix somewhere that compares the two > languages.

Gee, that's a hard question to answer. Rather than risk a language war, why don't you give it a try, and see what you find? Just reading some docs doesn't really give you a feel for a language. (The comparisons may help pinpoint some things, though.) Incidentally, i recall that someone from the perl part of the recent o'reilly open source conference was saying how perl needed something like zope to better handle the cgi domain. I'm wondering if thats what brought your attention to Zope? In any case, you may find getting acquainted with python to be a nice side benefit. There are some striking internal similarities between python and perl - which makes some of the overt syntactic and data structural - and ultimately, deep design-ethic differences all the more striking. If nothing else, it should be interesting to get a feel for the ramifications of those different design decisions. Ken Manheimer klm(a)digicool.com

I got everything going except the above code. (Incidentally, where can I find a reference to functions like objectValues?) I even tried changing Event to Folder (knowing that I do have a sub-folder in this one), but still it displayed nothing. Any ideas? I also tried objectValues(['Event']), I saw that syntax somewhere, but that didn't help. Incidentally, what is the difference between using single and double quotes, and when should each be used?

Okay, "No" -- but the correct answer is "yes" :^) A while back there was a thread about incorporating crypto into Zope. Unfortunately, that would be a substantial time committment that would pay relatively few dividends. Moroever, the whole international/ITAR situation wrt crypto makes it very unattractive for a US company. Apache for https:// and ZServer for http://... sounds okay to me. --Rob

Passing parameters through a DTML Document to a ZSQL Method
by A J Wilson 03 Sep '99

03 Sep '99

Hi I have a DTML Document which is based on data obtained from an ZSQL Method. The ZSQL Method has a number of parameters which can be passed from the DTML Document to the ZSQL Mehtod via the following  This works fine for static values. However, I would like the user to be able to specify parameters dynamically by either entering or selecting values on a DTML Document. How could I go about passing parameters from a DTML Document (the one in which the user selects or enters values) to the DTML Document based on the ZSQL Method which then passes those values as parameters to the ZSQL Method.

Zope 2 - Oracle ODBC
by John Dell'Aquila 03 Sep '99

03 Sep '99

I haven't been able to open an ODBC connection to an Oracle 7.3 database under Zope 2. It used to work under 1.10.3. I've tried upgrading everything to no avail: Zope 2.0, ZODBC DA 3.01b2, NT Service Pack 5. The peculiar thing is that ODBC connections to a SQL Server 6.5 database work fine. I wrote an External Method that opens a connection though the odbc module and it too fails when connecting to Oracle but works with SQL Server! Does anybody have any insights? Thanks John Dell'Aquila <John_DellAquila(a)amvescap.com>

SSL?
by Steen Suder 03 Sep '99

03 Sep '99

Hi, Today, playing around with Zope 2, it struck me: How about https://, SSL or the like? When connecting from the "outside" to my Zope site, I'll expose my password (webmaster's password) and that's definitely a bad thing. How do I get around this? Will I have to use Apache in front of Zope? (Please, say no...) -- Best regards / Mvh., Steen Suder sysadm kollegie6400.dk OpenSource --- Sign of the time
