Browsers & Backgrounds
by Robert OConnor 08 Apr '99

08 Apr '99

When I use this html tag: <body background="grytxtr7.jpg" bgcolor="#FFFFFF"> It shows up in Netscape 4.5 but not IE 4 as the expected background. (Win98) On another Non Zope site, this tag works fine with IE4. I've tried renaming the file in the index_html and the file itself both from Netscape and IE 4. I've shut both browsers down and even redialed the ISP to get a new IP but the problem remains. Has anyone else seen this? Is there a way to capture the transactions between the browser and server to see what is going on? -bobo connor bob(a)rocnet.com

ZServer won't run
by Philip Aylesworth 08 Apr '99

08 Apr '99

Well, I decided to take the plunge into ZServer. I installed it on my system but it won't run. I tryed the patch to start.py that was suggested for another ZServer problem but that didn't help. I assume that since I am using Zope 1.10.2 that I do not need to replace lib/python/OFS/Folder.py with the one suplied with ZSEever. I am running Zope 1.10.2 on Redhat Linux 5.2. My Zope directory is /usr/local/Zope I modified start.py as such: #!/usr/local/Zope/bin/python # configuration variables # IP_ADDRESS='192.168.1.16' HOST='pc16.regalint.com' DNS_IP='192.168.1.12' HTTP_PORT=9673 FTP_PORT=8021 PCGI_PORT=88889 PID_FILE='Zope.pid' MODULE='Main' LOG_FILE='ZServer.log' Here is what I get: [root@pc16 ZServer]# ./start.py Traceback (innermost last): File "./start.py", line 17, in ? from medusa import resolver,logger,http_server,asyncore File "./medusa/resolver.py", line 181, in ? import asyncore File "./medusa/asyncore.py", line 427, in ? import FCNTL ImportError: No module named FCNTL But it does exist: find .. -name FCNTL\* ../lib/python1.5/plat-linux2/FCNTL.pyc ../lib/python1.5/plat-linux2/FCNTL.py ../lib/python1.5/plat-linux2/FCNTL.pyo Can anyone help?

Hello, I live in the CEST timezone (gmt+1) I have problem with the calendar tag: it says : Error:DateTimeError Error Message:Unrecognized timezone inside DateTime.py they are references to a lot of zone (after class_cache:) but no mention of 'CEST'. a DTML like: time:.<br> produce no information, The normat var ZopeTime works well.I have RH 5.1 ,zope 1.10.2, python 1.5.1 Is it normal? Is the CEST reference missing inside DateTime.py? Or shall I move to another country?? Gilles Lavaux

Apologies for bad code :^(
by Rob Page 08 Apr '99

08 Apr '99

Yesterday I posted what I thought to be a solution to the dtml_source question. I copied it _directly_ from one of our machines which must be running one of Jim's, um, "special recipes." Apologies for sending our bad code and thanks to everyone that helped get the thing working! ... Jiiiiiimmm!!!!!!! --Rob -- Rob Page V: 540 371 6909 Digital Creations http://www.digicool.com

Little ZSQL snippet
by Tony McDonald 08 Apr '99

08 Apr '99

Just so's you don't think I never get *anything* to work... :) I was showing a colleague how to do some Zope SQL lookups. Tres Neat. Then it came to passing a parameter to the ZSQL method. get_single_event is the following ZSL method argument:: event_num SQL:: select event_num, event_title, DATE_FORMAT(event_date, "%H:%i %W, %M %D") as event_date, event_venue, event_details, event_speaker, event_contact, event_email, upload_ip, DATE_FORMAT(upload_date, "%W, %M %D %H:%i") as upload_date from event where event_num =  The code that calls it is;  # ie make sure that event_num exists  # you *don't* need to make event_num a parameter! <TABLE BORDER="0" WIDTH="100%"> dump your data... and the whole things works beautifully. I had tried  , ,  and all sorts of combinations with no joy. Learning more Zopista tricks day by day... hope this helps, tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

RE: [Zope] How do I replace the top level acl_users folder.

Ack. This is something we need to fix somehow. The problem is that if you get rid of the top-level userfolder, there is nothing to perform authentication/authorization and the site is effectively inaccessible :( I have come up with a fix for this that will appear in 1.11.0. You will now be able to delete the top-level user folder in order to replace it. Note, however, that during the time that you have no top-level userfolder, the mgmt interface for the top-level folder will be accessible *only* to the superuser. The fix involves only two files in lib/python/OFS/: Application.py and ObjectManager.py. I have attached new versions of these files that you can drop into your 1.10.2 installation if you like. After replacing the files, restart Zope and you should be able to replace your top-level userfolder with a userdb or other userfolder-like object. Let me know if you have any problems!

I just tested this out, and appart from Rob's code being broken and containing unreachable code it was close. :) Here's my method: import string def view_source(self, path): id = string.split(path, "/")[-1] if not id: id = 'index_html' if not id in self.objectIds(): id = 'index_html' doc = getattr(self, id) return doc.read_raw() The DTML:  <H1>DTML Source for </h1> <pre>  </pre>  There is no 'documentIds'. It would be pretty simple to add however. This must be a holdover from Principia which was either removed or lost, I think Rob is still running Principia on his DOS based 386. :) -Michel > ------ > Dr Tony McDonald, FMCC, Networked Learning Environments Project > The Medical School, Newcastle University Tel: +44 191 222 5888 > Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2 >

It's not too tricky and kinda snazzy in that you can create your own login/logout pages, etc. Check out the source of either package for the details. -Michel > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Linux Expo & PR & Wired
by Robert OConnor 08 Apr '99

08 Apr '99

Hi Paul, >We are focusing on Linux Expo (May 18-22, www.linuxexpo.org) as a focus >point for us where a number of things are going to come together: >1) I'll be giving a speech on the business track about Open Source and >Venture Capital. I'm thrilled to see you promoting ZOPE. If you havn't seen the May issue of WIRED you should check it out. There are three articles of interest: 1) "Open Season - - why an industry of cutthroat competition is suddenly deciding good karma is great business --" Has graph that shows the ONLY OS gaining market share is Linux. ('97 to '98). Another shows Apache moving from 45% to 54% Jan 98 to Jan 99. And more interesting a 25 person Lan: Microsoft vs Linux including support: $21,453 vs $5,544 2) "Tour de Source -- A guide to the Start-ups" 22 Open Source companies listed in table Alas, Digital Creations is not listed :-) Four companies with only 10 employees are listed. How big is Digital Creations now? 3) "Free Enterprise -- An open source success story--" Good story of Cobalt a company that sells Linux servers: Cube, RaQ, CacheQube etc... Hey, I could see ZOPE being bundled in a Cobalt box either directly or perhaps more quickly as a VAR product. >2) We are working with a professional PR firm (read: expensive) to >coordinate a branding overhaul and PR push. We are positioning Zope as >an application server focusing on community portals. The >under-discussion brand of the company is "unleashing potential", which >is based on Open Source, community portal, safely delegating control, >and through-the-web everything. The PR firm will cultivate opinion >makers in advance, schedule one-on-one interviews, and make appropriate >press releases. Even though the PR firm is expensive, I hope they are good, i mean, GREAT ! Hopefully they are into the web and the computer industry and can get coverage with some of the previously mentioned contacts in infoworld, linuxworld, wired etc.... >4) We are coordinating some software efforts to coincide with the show. >For instance, beta1 of Zope2 will be ready by then, knock on wood. >Also, some efforts to fill out our portal story (such as Membership, >Catalog, etc.) will land. I'd love to hear more information about the community portal idea. I know of a few organizations that would benefit from their own portals. Anyone doing this yet? -- even alpha or beta? >As part of the PR push we need some of you out there to ride the wave >with us and give us some case studies. This is both crucial for Zope >and a great benefit to you! Yes, I hope to have a Case study for you. Currently I'm testing zope "on the internet" and not just my LAN with a Zope host: (Thanks Scott Robertson) http://www.codeit.com My site for now is at http://rocnet.codeit.com -bobo connor bob(a)rocnet.com
