In the root.... A DTML Method.... Some objects (mostly DTML Documents) have a property (boolean) that tells whether this is a helppage or not. What I want to do is to loop though eash and every object in the entire site (not very big) and check if the object has this property. <pseudo code> <dtml-in "objectItems(['*'])"> <dtml-if ahelppage> <a href="<dtml-var id>"><dtml-var document_title></a> </dtml-if> </dtml-in> Any other good solutions are welcomed!

Manager Authentication Failure: How to debug?
by Kimmo Kansanen 12 Sep '00

12 Sep '00

Hi all, I just installed the latest Zope available for Debian (2.2.1) on Potato. However, after logging in as superuser and creating the manager account, I cannot log in with that account. The logs produced (that I found) only indicate the ZServer getting the http request, but nothing on the authentication failure. How should I proceed debugging the problem?

Albert, I've put this in the collector as a possible bug... hopefully it will get fixed with the next release if it proves not to be the proper behavior. In the meantime, you want want to try messing around with that regex to get the appropriate behavior for your environment. aboulang(a)ldeo.columbia.edu wrote: > > I've done a little poking around in ZPublisher's HTTPRequest.py and > BaseRequest.py and I don't think that's where the ';*' gets stripped.

Re: [Zope] Using Chinese Characters
by icottee＠bluefountain.com 12 Sep '00

With reference to inputting chinese characters I have similar issues within handling Japanese. My two solutions are either use Internet Explorer (if you have a windows machine) and use their add on extensions (download 5.5 and look at the extra options during download setup) or use emacs with MULE. Obviously there are limitations with the emacs method with what you can and can not edit. Some distributions of Linux will allow you to setup your environment in both Japanese and English and toggle between the. I think the same is true for Chinese. Try Kondara at http://www.kondara.com - I saw a demo of their new version at the Linux Expo which seemed to work well. Apart from playing with a Japanese distribution for fun I haven't done any serious work with these. Note that if you ever want to start storing your characters in external databases you will need to make sure that it can handle your encoding as well. MySQL has to be compiled with a certain config flag and I believe the same is true with Postgres. Otherwise strange things will happen :-) Ian

GDChart on Linux
by Hung Jung Lu 11 Sep '00

OKie, I now remember I did succeed in building GDChart on Linux. :) Let me repost here a message exchange with Mike Steed a while back in the Python mailing list, so in the future I won't get lost again. :) Hung Jung ============================================== From: Mike Steed <msteed@f...> Date: Sat Aug 12, 2000 4:01am Subject: Re: GDChart Hung Jung Lu wrote: > >Hi, > >Does anyone have experience with GDChart (Python interface to GD)? > >http://www.fred.net/brv/chart/ > >I tried to install it on Linux, the make process seems fine, but I get the >following error in Python: > > >>>import gdchart >Traceback (innermost last): > File "<stdin>", line 1, in ? >ImportError: ./gdchart.so: undefined symbol: gdImagePng > >Any help is appreciated. I became aware of this problem several days ago, but being the slacker that I am, I have not yet put an updated archive on the web. Here's the fix. In gd-1.8.1/Makefile, change line 18 from: CFLAGS=-O to: CFLAGS=-O -DHAVE_JPEG And change line 25 from: LIBS=-lm -lgd -lpng -lz to: LIBS=-lm -lgd -lpng -lz -ljpeg Then if you rebuild libgd and the Python interface, it should all work. Sorry for the hassle. >regards, > >Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

WOWDamn !! ZopeNewbies wakeup
by Jason Cunliffe 11 Sep '00

This is for any+all of you new to Zope.. and for those like me who have been struggling with DMTL for too long. I just found a perfect *gemstone* burried in 'Chapter6 - Advanced DTML' of the online sample of the O'Reilly Zope Book at http://www.zope.org/Members/michel/ZB/AdvDTML/view """ The REQUEST namespace is very useful in Zope since it is the primary way that clients (in this case, web browsers) communicate with Zope by providing form data, cookies and other information about themselves. A very simple and enlightening example is to simply print the REQUEST out in an HTML page: <dtml-var standard_html_header> <dtml-var REQUEST> <dtml-var standard_html_footer> """" Try it...beautiful and yes very enlightening. This should be on www.zope.org PageZero in my opinion I never saw a single line of ZopeDTML which so well demonstrates what it is capable of and why it _is_ cool when you know what to type. Get this book in Print asap please! thanks - Jason PS. Be warned: <8-() if you try put the code above in a DTML methods named 'showREQUEST' or 'show_REQUEST' it will not work = 'Id already in use' ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

I assume that you somehow managed to assign a non-list value (maybe None or a number) to a list valued property. Dieter
