RE: [Zope] dtml-if and checkboxes

<dtml-if check_box> <dtml-if expr="check_box == ('on')"> The check box is checked! </dtml-if> </dtml-if> The above should work, but there may be a better way... Maybe something like <dtml-if "check_box and check_box == ('on')">, not sure though. Scott -----Original Message----- From: Hires, Russell (CAP, CARD) [mailto:Russell.Hires@gecapital.com] Sent: Friday, October 04, 2002 1:15 PM To: 'zope(a)zope.org' Subject: [Zope] dtml-if and checkboxes Hey All, I'm experimenting with zope again, playing with the REQUEST object and form objects. In my latest delimma, I've got the following snippet: <dtml-if expr="check_box == ('on')"> The check box is checked! </dtml-if> What I don't get: if the checkbox is checked in the form, then this works, and I get the output. If it isn't checked, then I get an error saying that the checkbox ("check_box" in the form) isn't defined. This is borne out as well by <dtml-var expr="REQUEST.form">, which shows a text box's name and the value that it holds (whether it holds a value or not), and the checkbox's name and value ('on'), when it's checked. If it isn't checked, it isn't there at all. So, I guess I'm going to have to look to see whether it's there or not, right? How would I do that? Thanks for the help!

Re: [Zope] Redhat 8.0 and Zope (mod_python)

Chris: Zope doesn't run on mod_python. Why would you want it to? Stephan: Why not? There is mod_perl which is very good. I would be interested in the dis-/advantages of using it. Chris: You're attempting to compare apples and oranges. Paul (quoting Stephen Alexander): "You are comparing apples to an entire fruit salad served with cream." ;)

Howdy, Can anyone tell me when the STX "My Picture":img:MyPicture syntax will be working? I just installed 2.6.0b1 and it renders as <a href="img:MyPicture">My Picture</a> Thanks, Kent

Help system products?
by Richard Wesley 04 Oct '02

04 Oct '02

We are building a web application in Zope and the question has arisen about how we build the help system. Stuff we need: - Page help - User's Manual - FAQ My initial reaction (partially motivated by hideous deadline pressure) is to just slap a Wiki in the help folder and muck with the presentation details later, especially since the Wiki source files are so darn simple. Is this a reasonable plan? Anyone have a better solution?

hi in an attempt to provide users with list of those online, i'm using session to keep track of who's logged in , and who's timed out (inactivity) in essence, -when users log in, i start a session, and store their username in the session object -i then have an external method that goes thru session data in temp_folder (where session objects are stored) and iterate thru the session objects, and return the usernames[1] this scheme works, but some, maybe many, times, i encountered Key Error[2, and many times it's the same key error]. is there anything wrong with my way of approcahing this? or is there a better way? zope2.5.1/zope2.6.0b1, python2.1.3, linux help appreciated. tia -- [1] def getsession_data(self): import time l = [] for session in self.temp_folder.session_data.values(): username = session.get('username','Unknown') last_xs = time.ctime(session.getLastAccessed()) l.append((username,last_xs)) return l [2] Error type: KeyError Traceback: <p>Traceback (innermost last): <ul> <li> Module ZPublisher.Publish, line 98, in publish</li> <li> Module ZPublisher.mapply, line 88, in mapply</li> <li> Module ZPublisher.Publish, line 39, in call_object</li> <li> Module OFS.DTMLMethod, line 126, in __call__</li> <li> Module DocumentTemplate.DT_String, line 474, in __call__</li> <li> Module DocumentTemplate.DT_Util, line 201, in eval<br /> __traceback_info__: sc_gSessionData</li> <li> Module <string>, line 2, in f</li> <li> Module Shared.DC.Scripts.Bindings, line 252, in __call__</li> <li> Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec</li> <li> Module Products.PythonScripts.PythonScript, line 315, in _exec</li> <li> Module Script (Python), line 1, in sc_gSessionData<br /> <b><PythonScript at /kk/sc_gSessionData></b><br /> <b>Line 1</b></li> <li> Module Products.ExternalMethod.ExternalMethod, line 231, in __call__<br /> __traceback_info__: ((), {}, None)</li> <li> Module /home/xxx/ZopeHome/Extensions/session.py, line 30, in getsession_data</li> <li> Module Products.Transience.Transience, line 832, in values</li> <li> Module Products.Transience.Transience, line 832, in <lambda></li> <li> Module Products.Transience.Transience, line 755, in __getitem__</li> </ul>KeyError: 1033629200 </p> -- http://www.kedai.com.my/ http://www.kedai.com.my/eZine http://www.zope.org/Members/kedai http://www.my-zope.org I will follow you!

Re: [Zope] Getting zctl.py To Start ftpd-- Was: Is Anyone Listening?? Port 8021 Isn't!
by David Shaw 04 Oct '02

04 Oct '02

I'm pretty sure the confusion comes from my AdvancedSiteSetup tutorial here: http://www.zope.org/Members/dshaw/AdvancedSiteSetup I usually leave the Zope ftp server off for production systems, because I never use it, and it could be a possible security hole to leave an unmonitored service running. That's why in my sample configuration zope.conf it is set up like this: ZOPE_OPTS = '-p - -f -' That command DISABLES the internal ftp server. You enable it in zope.conf like this: ZOPE_OPTS = '-p - -f 8021' Where 8021is the port you want to use. Then restart zope: ./zctl.py restart Hope that helps. - David On Thursday, October 3, 2002, at 12:00 PM, zope-request(a)zope.org wrote: > Date: Thu, 03 Oct 2002 10:53:54 -0400 > To: Doug Hellmann <doug(a)hellfly.net> > From: beno <zope(a)thewebsons.com> > Subject: Re: [Zope] Getting zctl.py To Start ftpd-- Was: Is Anyone > Listening??

RE: [Zope] ZPT changing javascript (HOW?) - Easy with DTML
by sean.upton＠uniontrib.com 04 Oct '02

04 Oct '02

Perhaps I'm late to this conversation, so I might be misunderstanding the context, but I have another ZTP script tag problem... In the HTML 3.2/4.0 specs, stuff in script tags is implicitly CDATA in HTML (though not in XHTML). ZPT does not respect this, so JavaScript with '<' or '>' inside JS string literals causes problems with parsing the PT. IMHO, this is a bug unless the PT in question is set explicitly to XML? Has anyone else encountered this? Does anyone mind if I file this in the collector? Eaxmple would likely fail ZPT parsing: <script> document.write('<a href="' + somevar + '">" + someothervar + '</a>'); </script> Thoughts?

Deckard; Mike Renfro Cc: zope(a)zope.org Subject: RE: [Zope] ZPT changing javascript (HOW?) - Easy with DTML Speaking here as someone who knows XHTML and XML but not ZPT: This probably won't work. <script> isn't supposed to contain other tags. Go read the FAQ on the XHTML validator for some idea of how javascript and XHTML just don't mix well. Consider moving your script into python or dtml. Also, you shouldn't do this for empty elements: <sometag/> You should always place a space in there: <sometag /> Again, see the XHTML spec, validator, and validator FAQ. > -----Original Message----- > From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of > Christopher N.
