Conferencing Groupware
by Jason Cunliffe 26 May '00

26 May '00

Hello veyone I am researching Conferencing groupware application designs and platforms. I welcome any feedback from you all. My immediate aim is to outline the potential for implementing a system using Zope. Right now I want to describe a [mageable]indicative sample of exisitisting ones. In the back of my mind is always 'XCollage' which was a lovely work also developed at NCSA around the same time as XMosaic [greatgreatgrandmama of Mozilla]. http://www.ncsa.uiuc.edu/SDG/Software/XCollage/collage.html Its integrated whiteboard was a particularly nice feature. I only ever saw Collage running on SGI machines, but I believe it is simply an One real plus is that Collage was designed by and for scientists not b2b goons. "Collage is a collaborative data analysis tool. It is intended for doing data analysis either alone or simultaneously with several people who are on the same network" It embraced HDF, a data format used for earth observation and much more. HDF has been adopted as a standard format for the Mission to Planet Earth (MTPE) project, of which the key component is the Earth Observing System Data and Information System (EOSDIS). http://hdf.ncsa.uiuc.edu/ What I really want is that combined with a more 'mature' Zwiki capable of handling tables and graphics [Flash, SVG, livedrawing]. easy right? ;-) Do any of you have direct experience with groupware confrencing/whiteboard tools? Some have mentioned MSNetMeeting to me... My interest here is in general functions and features and how they _might_ be integrated with zope, not in starting a ny flamewars. A key issue is the ease of use. Zwiki _almost_ makes it except that people seem to get lost too easily and want more visible structure enabled. Manila is nice for its clean direct results, but does not run on Unix, is expensive and also apparently lacks sufficient documentation. etcetc TIA - Jason ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

Pages not showing up - on the fly or via LocalFS
by Jim Sanford 26 May '00

26 May '00

Have dtml method that creates html page that is mostly 1 big table. When the size of this page approaches 150k Zope hangs and never serves it up. If I us _.render to render the page to a file and try to deliver the file via LocalFS it does not show up. If I use my lan and and go directly to the page LocalFS wouldn't serve it comes up without hesitation - it just won't serve through zope. If I lop enough rows off the document with an editor to get it's size down to about 130k it will then render through LocalFS. These files have no graphics. Any ideas???? __________________________________________________________________ Jim Sanford .

dtml-break ?
by calvin33 26 May '00

26 May '00

Catalog iterative & break : <dtml-in "my_catalog"> <dtml-if "my_condition"> <dtml-var "getobject(data_record_id_)"> <dtml-break> . . . But i have get nothing ! Why ? I am sure that "my_condition" is right because it will show some object without "dtml-break" .

i am using internet explorer 5, trying to connect to this page, 1 isp allows connection every time, the other doesn't at all. i was hoping to change to the one that doesn't permanently & get rid of the other. is there any way to get around this. i think its something to do with cgi scripts being accepted by the isp. it is mentioned in the zap document very briefly. does anyone know an answer? thanks michael

Controlling HTTP_REFERER
by John Hile 26 May '00

26 May '00

Can anybody suggest a good technique for controlling what gets sent in the HTTP_REFERER header when users click on links to pages outside your own site. We are setting up a secure server that may occasionally contain links to outside sites. Normally, the browser passes the complete URL of our current page in HTTP_REFERER when a user clicks on one of these links, but there may be information in the URL that we want to protect. I tried simply setting up a page on our site with a redirect to pass the links through, but the browser still passes the original URL. Any suggestions for a good way to handle this are welcome.

Passing all POST variables?
by Andrew H. Chatham 26 May '00

26 May '00

Hello Zope-people, I'm writing a LoginManager plugin for a quiz-taking website, and I have cookies which expire after a manager-defined time. If someone's taking a quiz for longer than the cookie duration and their cookie expires, they're going to have to relogin, but I would rather not lose what data they've entered already. I have a separate login page so it can be under SSL, and I adapted the given loginForm and took it's ability to maintain GET data by passing the QUERY_STRING variable onto the login-success page and reconstructing the URL there and redirecting to it. This works great, but I'd rather not limit people to passing things in GET, for various reasons (quiz answers showing up in the browser history, requests being too large, etc.). But I don't know what the variables are beforehand, so I can't just pass them along. Is there any way to pass along all of the POSTed variables through the login page so that I can redirect to the desired page later with the values intact? Is this a lost cause? I don't mind if it would require Python to do it, but is it even possible? I have no idea how to tackle that, but I didn't even know about the QUERY_STRING variable before I saw the LoginManager DTML, so maybe there is hope. Of course, I'm not even sure this would even work HTML-wise, since I don't know a way to pass GET data and do a redirect at the same time. May not be possible (is there a workaround for that?) Oh, and I have absolutely no opinion on Perl ;-) Thanks, Andrew

newbie question: parameter passing for ZSQL Object
by Andy Pahne 26 May '00

26 May '00

It's pretty easy: <dtml-call "sql_method(argument1=value1, argument2=value2)"> There's a problem with your SQL-statement: >INSERT INTO plan >(field1, field2, field3, field4) >VALUES >(<dtml-var param1>, <dtml-var param2>, <dtml-var param3>, <dtml-var param4>) It should be: INSERT INTO plan (field1, field2, field3, field4) VALUES (<dtml-sqlvar param1 type=string>, <dtml-sqlvar param2 type=string>, <dtml-sqlvar param3 type=string>, <dtml-sqlvar param4 type=string>) Andyman
