Getting email fields right
by Bruce Eckel 29 Nov '01

29 Nov '01

I'm using the MailHost to send email from within an external method. I've tried a number of different combinations, including something as elaborate as this: self.MailHost.send("This is a test", # Body "To: Bruce Eckel <Bruce(a)EckelObjects.com>", "From: Bruce Eckel <Bruce(a)EckelObjects.com>", "Test Email") # Subject However, I can't seem to get the "to" and "from" fields to show up right in the resulting email. All I end up with is a 'to' field of Bruce(a)EckelObjects.com and an empty 'from' field. I suspect others have done this before and solved the problem. Or will want to :-) Most current information can be found at: http://www.mindview.net/Etc/notes.html =================== Bruce Eckel http://www.BruceEckel.com Contains free electronic books: "Thinking in Java 2e" & "Thinking in C++ 2e" Please subscribe to my free newsletter -- just send any email to: join-eckel-oo-programming(a)earth.lyris.net My schedule can be found at: http://www.mindview.net/Calendar ===================

Anybody using xinetd with Zope?
by earth_to_zope＠space.com 29 Nov '01

29 Nov '01

Hi all, Zope newbie with a question about xinetd. At least I suspect that xinetd is where my problem resides. I can access my zope app from on campus, but my client can't see it off-campus. I don't use xinetd to start or stop zope, but isn't that where you allow/limit access to different ports (mine is running on port 9673). Or is this a problem with the corporate firewall that is having problems seeing the Zope app. Can YOU see it? http://touchstone.unk.edu:9673/kearney Any pointers would be appreciated. Please Cc me when you reply to the list, as I'm currently having a problem receiving list messages. THANKS!

Question: I have extracted data from a database using a Z SQL Method. Now I want to know the names of the fields of the records retrieved. How do I do this? In the documentation I keep finding: "They provide meta-data about their input parameters and result data." How can I access this metadata? Hans-Peter Harmsen

Getting a "Handle" to a ZODB object to store in another object
by John Ziniti 29 Nov '01

29 Nov '01

Hi all, I would like to have an object in one folder be referenced by another object in another folder (think symlinks in UNIX) ... but I'm not sure what properties an object has that identify it's absolute location (absolute_url is a little fluffy, no?). Anyone have any ideas on how to approach this? Thanks in advance, Ziniti

Document Library: Changing Properties
by Jason C. Leach 29 Nov '01

29 Nov '01

hi, I have 108 documents in a Document Library (product). I need to go through them all and set one propertie equal to another. Something like document.x = document.y. I figure this is a good time to learn python scripting in zope. I don't know how to get the documents into my script, then back out. Any help would be appreciated.

Question about Ram Cache
by Chris Kratz 29 Nov '01

29 Nov '01

Hello All, Recently, we have been doing a lot more caching of various parts of our website. We have noticed two times over the last week that after a restart and a long period of relative inactivity (overnight) that one of the pages has gotten corrupted. Invalidating the page in the ram cache and forcing it to reload takes care of the problem. The first time the HTML was corrupted (parts were missing) and in the second case, none of the images (which are also cached) would show even though those same images on other areas of the website displayed correctly. The page is quite simple and includes only static text with a header and footer that is generated with a date and the generation time for the page. The only REQUEST variable is AUTHENTICATED_USER which means that all anonymous views get the same cached page. Here are the other settings we are using: Threshold entries: 1000 Max Age: 3600 Cleanup interval: 300 Also, there are no Names from the DTML namespace currently being used as cache keys on the page in question. Since this is such a basic application of the Ram Cache, I am a little surprised that we would be seeing this type of behavior. Anyone have any ideas why this might be happening? RH 7.2, Zope 2.4.1, Python 2.1.1 Thanks, -Chris ------------------------------ Chris Kratz chris.kratz(a)vistashare.com

Image product that works with Zope and ColdFusion AND has to run on Winblows
by Tommy Johnson 29 Nov '01

29 Nov '01

Hey all, Does anyone know of a product that will fulfill these requirements: 1. Works with Zope *AND* ColdFusion (could also work with ASP, php, etc.) 2. Runs on Winblows (more on this later) 3. Free (if not, then I might be able to get the client to pay, but ....) The situation is that I have a friend who has influence (however little it may be) over his boss. His boss runs a Microsoft shop, and I've been trying to get them to switch (or at least try) to Linux. Nada.... Anyway, they obviously do a lot of ASP, but have started with ColdFusion. Somehow, I've talked them into trying Zope. The situation is that the Photo gallery project must run on a Windows server. No problem if the product works with Zope, and can run on a Windows box. But they also want the product to work with CF, at least. What they don't want is the interface I build using WordConverter, which has to run on Linux; it isn't supported on Windows. So, I'm walking on a fine line (not to mention my friend..lol). *why can't these people switch to Linux....well, maybe in time.....after all, they _are_ trying Zope!* Thanks in advance, Tommy Innovation: The Best Way To Predict The Future ...
