Starting zope automatically on Linux Mandrake 8.0
by Karl Munroe 13 Jun '01

13 Jun '01

I have one for all you linux gurus, I recently installed Zope 2.3.2 after much headache..finally it work that to help from Chad Crawley. I have a problem with linuxconf picking up the zope script from /etc/rc.d/init/d. The file exists and it has execute permissions. I can : ./zope {start|restart|etc..} form the command line. However, when I try to restart the zope server from linuxconf it does not report it as a service and zope does not start automatically when the server is rebooted. Is there a special script editor to use?? Or can I just use pico to edit the text in the script? Do i need to include the infomation to start zope automatically anywhere else?? Does anyone have a pdf on how to write the scripts??? Thanx in advance, Karl Munroe P.S. The How-to Start zope on linus Redhat did not work for me on Linux Mandrake

Working on Zope presentation
by Timothy Wilson 13 Jun '01

13 Jun '01

Hi everyone, I'm going to be doing a presentation on Zope at the July meeting of the Twin Cities Linux Users Group. I'm looking for suggestions from others who may have done a similar presentation regarding what topics I should cover. I'll be looking at some of my own projects as case studies, but what else would people recommend covering? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.org W.

Hmmm, well I haven't seen it in documentation, but the documentation may exist. To tell the truth, I just learned that last week when C. Duncan came up to teach Zope/Python training at my company. There a story behind why it is named that. It was once a part of one project that merged with another project. These to projects formed Zope, but for some reason the variable names (well, not all of them at least) didn't get changed to something more intuitive.

Just to let the list know (and people that have run into similar problems): After a long fight to get MySQL and Zope to talk to one another we got it going!!! This little bit of information: >Date: Thu, 7 Jun 2001 20:14:04 -0400 (EDT) >From: Andy Dustman <andy(a)dustman.net> > >ZMySQLDA-1.1.3 is not compatible with MySQL-python-0.3.5. Instead, try >ZMySQLDA-2.0.7 with MySQL-python-0.9.0. >http://sourceforge.net/projects/mysql-python along with installing Distutils (and other various requirements mentioned in the documentation) on a non Zope Python 1.5.2 Version and copying the needed folders and files mentioned in the error messages from standard python install to Zope python install did the trick (as well as various nitty gritty configuration settings because of our "non standard" system and system setup). I am sorry it is not more detailed, but we were about to give up and as a last resort started trying some crazy things (without documenting it): and like magic... it started to work (and has been running ever since).

Erratic zope error
by Sherman Lambert (State Public Defenders Office) 12 Jun '01

12 Jun '01

Hey Gang, I'm running our intranet using Zope. This intranet serves offices across the state of Colorado (USA). I'm having users get zope errors "resource not found" in some locations. At the home office where I work I cannot duplicate this. The error usually occurs on pages the do a ZSQL queries to a Postgres database. These table are very small (under 50 records). Does anybody have any idea why I'm getting SERVER SIDE errors at distributed locations?? Thanks, Sherman

The problem lies not in zope, it's the browser (I use IE 5.00.dontaskme). First it goes to http://www.spiderplant.net/dan/redirect.php: ==> GET http://www.spiderplant.net/dan/redirect.php HTTP/1.0 ==> Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* ==> Accept-Language: de ==> Accept-Encoding: gzip, deflate ==> User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT; QXW03336) ==> Host: www.spiderplant.net ==> Proxy-Connection: Keep-Alive ==> [0.070 - Server connected] <== HTTP/1.1 302 Found <== Server: Apache/1.3.12 (Unix) PHP/4.0.4 mod_perl/1.24 mod_ssl/2.6.4 OpenSSL/0.9.5a <== X-Powered-By: PHP/4.0.4 <== Content-Type: text/html <== Date: Tue, 12 Jun 2001 20:36:40 GMT <== Location: http://www.spiderplant.net:8080/anticlimax/index_html <== Proxy-Connection: Keep-Alive <== <== owser bug <== [0.210000 - Closed by Client] (Does anybody now what "owser bug" above should mean? Is this a sign?) You see it gets the redirect (302) and this happens: ==> GET http://www.spiderplant.net:8080/anticlimax/index_html HTTP/1.0 ==> Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* ==> Accept-Language: de ==> Accept-Encoding: gzip, deflate ==> User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT; QXW03336) ==> Host: www.spiderplant.net ==> Proxy-Connection: Keep-Alive ==> [0.040 - Server connected] <== HTTP/1.0 200 OK <== Server: Zope/Zope 2.3.2 (binary release, python 1.5.2, linux2-x86) ZServer/1.1b1 <== Content-Type: text/html <== Date: Tue, 12 Jun 2001 20:36:40 GMT <== Content-Length: 1261 <== Proxy-Connection: Keep-Alive <== <== <html> <== <head> <==  <== <title>Anticlimax</title> <== <link rel="stylesheet" type="text/css" href="http://www.spiderplant.net/anticlimax/stylesheet"> <== <== <script language="JavaScript" src="http://www.spiderplant.net/anticlimax/main/JavaScript/NewWindow.js"></script> <== [snip] ==> GET http://www.spiderplant.net/anticlimax/main/JavaScript/NewWindow.js HTTP/1.0 ==> Accept: */* ==> Referer: http://www.spiderplant.net:8080/anticlimax/index_html ==> Accept-Language: de ==> Accept-Encoding: gzip, deflate ==> User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT; QXW03336) ==> Host: www.spiderplant.net ==> Proxy-Connection: Keep-Alive ==> <== </body></html>HTTP/1.1 404 Not Found <== Date: Tue, 12 Jun 2001 20:34:29 GMT <== Server: Apache/1.3.12 (Unix) PHP/4.0.4 mod_perl/1.24 mod_ssl/2.6.4 OpenSSL/0.9.5a <== Connection: close <== Content-Type: text/html; charset=iso-8859-1 <== <== <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <== <HTML><HEAD> <== <TITLE>404 Not Found</TITLE> <== </HEAD><BODY> <== <H1>Not Found</H1> <== The requested URL /anticlimax/main/JavaScript/NewWindow.js was not found on this server.<P> <== <HR> <== <ADDRESS>Apache/1.3.12 Server at www.spiderplant.net Port 80</ADDRESS> <== </BODY></HTML> If you look at the Host: header, you see www.spiderplanet.net.

As I see it, zope does the right thing... Perhaps you should use proxying instead of a redirect. cheers, oliver

A newbie question - ZClasses, contents, and so on...
by Carlson, Christopher W. 12 Jun '01

12 Jun '01

Hi, everybody. I'm trying to understand just how ZClasses work, and have decided to create a simple message board system with my ever-so-slowly growing knowledge. My model is this: A forum may contain multiple topics, each of which has a name. A topic, in turn, may contain several messages (each of which has an author and some content). (Yes, I know that ZDiscussions does this, but perusing the source hasn't helped me much.) After flailing at the problem for a while, I've tried two different approaches. 1) Each of the classes (Forum, Topic, and Message) are created in the 'CForums' product I've made. Forum and Topic both use ObjectManager as a base class, so they can contain other items (Topics and Messages, respectively). This works well as long as I create Topics and Messages manually, through the Zope admin screen, but I was unable to discover how to automate the process so a normal web user could do it. I simply couldn't figure out how to get to the Topic methods from within a Forum object, and so on. 2) Topic is a ZClass in the methods area of Forum, and Message is a ZClass inside of Topic. This works well enough, except that I can't specify Topic as a sub-object of Forum, and so on. Consequently (at least, I *think* it's a consequence of this), I can't use things like objectValues or objectIds to get to the 'contents' of a Forum, even though there are definitely messages tucked away inside. How should I be approaching this problem? I don't really need hand-holding, but a healthy shove in the right direction would be greatly appreciated. Thanks for any help you can offer. --- Chris
