Instead of using <input type=submit ...>, I use <input type=button ...>. I guess an example is better than long explanations. ------------------------------------------------------------------ <center> <form name=my_form method=get> <input type=hidden name=handling_method> <input type=button value="Notes" onclick="go_notes()"> <input type=button value="Edit" onclick="go_edit()"> </form> </center> <script language="JavaScript1.1">  </script> ------------------------------------------------------------------ In the first case (go_notes), your submission is sent to the "Notes" folder inside Zope, and it's handled by the conventional index_html method. In the second case (go_edit), your submission is sent to the "Person" folder and it's handled by the "method_edit" method inside the "Person" folder. The "method_edit:method" tag in the above code tells Zope that "method_edit" is a method. It's a Zope thing, and you won't find it in JavaScript books. I find it useful to put my methods that handle a Person inside the Person folder, so I can have something like method_edit method_delete method_update ... neatly lined up inside the Person folder. Another trick is, inside these handling methods, at the end I do a redirection, something like: <dtml-call "RESPONSE.redirect(MyNextPage.absolute_url() + '?person_id=%s' % my_person_id)"> That is, the handling methods only handle the logical part. For actually displaying the result, I use redirection to a displaying page. Oh, on the &dtml.url-...; notation: if you need more complicated URLs, you cannot use the "&dtml.url-Object;" notation. You have to use "<dtml-var "MyFolder.MySubFolder.Object.absolute_url()">" notation instead. Now you know how to make Zope work for you. :) regards, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

It would not expose passwords - I believe that what you are seeing is a sort of non-obvious but basically harmless thing. User folders (acl_users) do not have an index_html method (by design). When a DAV client tries to "download" acl_users, it is actually acquiring the closest index_html from above and downloading that :^) One could argue that this is lame and that attempting to GET .../acl_users/ should raise an error (404?). I'm interested in other viewpoints on this - if there is some consensus, a proposed change should be put in the Collector.

tree state cookie
by Ragnar Beer 05 Jun '00

05 Jun '00

Howdy! I just recently got complaints from people visiting my web site. They have activated the "website wants to set cookie" alarm and they got lots of alarms when visiting my website. Since I never use any cookies it wasn't hard to find the cause: I wasn't aware that trees use cookies to store their state. Is there an option to disable this? (Cuz I don't want no cookies;) --Ragnar

Hi! I would like to look up the properties on an html file that I've made. I've made a string on my html file, but I'm not sure how to call it! I've understood that a <dtml-in> is to be used, but I don't know what the string is called. Could someone help me with that!? /Martin S.

Copy/Paste cookie problem
by Oleg Broytmann 05 Jun '00

05 Jun '00

Hello! I constantly have cookie problem (at least I think it's cookie problem). I cannot copy/paste. What is worse, the behaviour is a bit inconsistent. I have two almost identical installations on two different computers. On one of them I can do copy/paste almost always. (Sometimes Zope doesn't show Paste button). On the other computer Zope dosn't show Paste almost always. When I reboot Netscape, I can do copy/paste for some short time, and then Zope again stops showing Paste button. To trace the problem I've add cookie module to filtering proxy that I'm using (http://theory.stanford.edu/~amitp/proxy.html) and can see the whole cookie sent/received log. Nothing suspicious in th log - browser sends and receives __cp cookie (along with other cookies). Example: (I do copy:) |<--!-- Cookie Received __cp="x%da%d3%60b%60%60%c8%04b%86hF%20%a1%01%e2%16%83%b9,%20%16%07%03%1c0%21q%98%85%909%12%c8%9c%2a%00%c6%0e%04%87"; Path=/pcgi (I switched to different folder:) |--!--> Cookie Sent tree-s="eJyLjlZ3hANPW/XYWAAtiQTP"; __cp="x%da%d3%60b%60%60%c8%04b%86hF%20%a1%01%e2%16%83%b9,%20%16%07%03%1c0%21q%98%85%909%12%c8%9c%2a%00%c6%0e%04%87"; dtpref_cols="55"; dtpref_rows="15" Browser sends all cookies; but Zope doesn't allow Patse :( Details, if this can help: Server1: sun.med.ru; SPARC, Solaris 2.5.1; Zope 2.1.4 (2.1.3 had the problem, too) Server2: phd.russ.ru; Pentium, Debian GNU/Linux; Zope 2.1.4. Both servers have Zope with additional components: SQL adapters, SiteAccess, ZNavigator, etc. The problem manifests itself whether I use Netscape for Linux or for Solaris; whether I use proxies or swith to "no proxy - direct connection". Few of my freiends here reported the same problem with different hardware, OSes, browsers, etc. Oleg.

Zope must be restarted often
by Josh Glover 05 Jun '00

05 Jun '00

Here is the problem, and forgive me if this is a known issue and I just could not find it in the mailing list archive. I am running Zope 2.1.6 under FreeBSD 4-STABLE (May 15). I am running Apache 1.3.12 with mod_ssl/2.6.4 and OpenSSL/0.9.4. Also, I am running Python 1.5.2. What happens is: Zope just stops responding to a browser lookup. I try to browse to it, and Netscape just shows that the server has been contacted and it says "Waiting for reply..." until it times out. If I killall the Python processes and then run the Zope.sh start script, everything is fine again. I have been unable to tie the failure to a time or specific event as of yet. Any help would be appreciated. Thanks, Josh Glover

Zope/Apache/NT
by Paul Smith 05 Jun '00

05 Jun '00

Has anyone managed/bothered to get Zope working with Apache on NT yet? If they have, could you point me at any documentation? This is intended as a quick fix until I can get round to installing Linux on my machine.. Any help would be greatly appreciated!
