Form Validation
by Andreas Pauley 06 Sep '00

06 Sep '00

Hi, I see you can let Zope do basic form validation for you by appending ":string" or ":int" to your form name. The error messages that are displayed are not that clear, however. How can I get more control over what happens when an error occurs? (e.g. I'd like to be able to get back a list/ditionary of errors instead of handling them one by one) Where can I get documentation on all the built-in form validation options at my disposal? (e.g. a field may not be required, but if it is filled in it has to be an integer) Is Zope's built-in form validation sufficient for a complex system? Are there better ways to do form validation? I saw a php program on freshmeat.net the other day that supposedly generates forms complete with client and server-side validation. Do we have a similar product in Zope? Thanks, Andreas. -- In a world without fences, who needs gates?

This is a correction for my last entry at the mailing list: problem with virtualhosts. The line: ProxyPassReverse /z http://www.deeldrie.nl:8080/deeldrie should be in this example: ProxyPassReverse /z http://www.myserver.nl:8080/myserver regards, Wouter

problem with virtualhosts
by Daan Wormsbecher 06 Sep '00

06 Sep '00

Hi all, My server is running with Zope 2.1.6 and SiteAccess 1.0.1. I followed the instructions of the very clear how-to created by Anser. But it there is one problem which I can't solve. I want to serve pages with Apache and with Zope. The url to serve pages with Zope should be: www.myserver.nl/z In the root of Zope I add a subfolder called mysubfolder. This folder should be the siteroot of this site. This is the configuration of my httpd.conf; ServerName www.myserver.nl NameVirtualHost 12.345.67.890 <VirtualHost 12.345.67.890 > ServerName www.myserver.nl DocumentRoot /home/httpd/html ProxyPass /z http://www.myserver.nl:8080/mysubfolder ProxyPassReverse /z http://www.deeldrie.nl:8080/deeldrie ProxyPass /misc_ http://www.myserver.nl:8080/misc_ ProxyPass /p_ http://www.myserver.nl:8080/p_ </VirtualHost> In 'mysubfolder' in Zope I added the following SiteRoot object: title: (ignored) base: http://www.myserver.nl/z path: / Till here everything goes fine. The url www.myserver.nl/z shows the correct pages. But the problem is in the management interface of Zope. The generated url in the main section of the management interface doesn't work anymore: Instead of sending the browser to www.myserver.nl/z/mysubfolder/mysubsubfolder, it is sending the browser to: www.myserver.nl/mysubfolder/mysubsubfolder which can't be found. I spent several days to solve this but I didn't found a solution. Can somebody please help me out with this problem? regards, Wouter

acl_users mystery
by Ragnar Beer 06 Sep '00

06 Sep '00

Howdy! I had a strange problem today: I added a Role "User" in the root's security tab and gave it a couple of permissions. But further down the tree in /de/support where in the acl_users folder I added a user with the role 'User' the permissions where not acquired (until set manually in the /de/support security tab I couldn't log in) although 'Acquire permission settings' was turned on all the way down the tree. Very mysterious. Did I misunderstand the whole idea or is there something wrong? (Zope 2.1.6) Ragnar

[ANN] Whois Tools for Python & Zope
by Dominic Mitchell 06 Sep '00

06 Sep '00

Just a small package that some people may find useful. When used with Zope, it creates a <dtml-whois> tag that does a whois lookup on a variable. For example: <pre> <dtml-whois "'zope.org'"> </pre> Will result in: ------------------------------------------------------------------------ Whois Server Version 1.1 Domain names in the .com, .net, and .org domains can now be registered with many different competing registrars. Go to http://www.internic.net for detailed information. Domain Name: ZOPE.ORG Registrar: NETWORK SOLUTIONS, INC. Whois Server: whois.networksolutions.com Referral URL: www.networksolutions.com Name Server: NS02.CODEIT.COM Name Server: NS1.DIGICOOL.COM Updated Date: 22-feb-1999 >>> Last update of whois database: Tue, 5 Sep 00 05:04:09 EDT <<< The Registry database contains ONLY .COM, .NET, .ORG, .EDU domains and Registrars. ------------------------------------------------------------------------ You can also explicitly specify a server to contact. Download it from: http://www.zope.org/Members/Dom2/whoistools/ Please let me know if you find it useful or find bugs. -Dom

Tracker weirdness

Hi everyone :-) I am trying (desperately) to use a Tracker on my own site. So I checked one out of CVS and started using it. I created some users for my website with their very own roles. Now when one of those users tries to view the issues listed in the Tracker (like someone would do on www.zope.org) we just get an error: (sorry about the lenghty posting) ----------------------------------------- Unauthorized You are not authorized to access issueSummaryRows.

ANN: want to localize your pages and/or zope?
by Tino Wildenhain 06 Sep '00

06 Sep '00

Hi, last night I realized my finger-trainnig called VaryTag :-) I talkt about it at EuroZope meeting in paris, but lost my old implementation during deleting of old zope instances. So it took me 3.5h to rewrite it from scratch. This time it works according to rfc2616 (HTTP/1.1). Its just one solution for serving multi language documents, but it works very well. I will soon localize the current zope with it as well as our websites will be localized. Its easy to use, just look at http://www.zope.org/Members/tino/Vary%20tag/readme/ Sorry for the ugly url with space, it was deep in the night ;-) Unfortunately zope.org has not installed the product already, so I was not able to give the readme in different languages .-)) Best regards Tino Wildenhain
