DTML calendar widget
by Ty Sarna 08 Feb '99

The was some talk long ago about calendar support of some kind in Principia. I don't know wwhatever became of that or what kind of features people were wanting, but this weekend I sat down and wrote a calendar DTML widget. You can try a sample instance of it at: http://www.endicor.com/zope/test/Calendar Those of you with Palm Pilots will find the interface familar :-) The sample page is generated with this source:   :    The chunk of code within the calendar tag is used to render the individual cells in the calendar display. It's called for each cell with the name 'date' bound to the date to be displayed, and 'mode' bound to either 'day', 'week', or 'month' depending on what mode the calendar display is in. The calendar tag takes a few optional arguments, including mode to start in (defaults to 'month') and an expression to compute the date to start on (default to current date if unspecified). Anyway, have a look. If you think it'd be useful to you, let me know!

What's "decodestring" in User.py line 388 for? or Begging a step for Internationaliztion. Internationaliztion.
by LEE, Kwan Soo 08 Feb '99

08 Feb '99

I've got an binascii.Error as the attached file. What I did was to get this error is the following. 1. Adding to a user folder a 'New User' whose id is composed of non-ascii characters. And there were no errors(this is true when I did the same to a user db). 2. Trying to access manage page as that 'New User' What I can see from the source code is 'v'(=validate) in User.py line 388 calls python builtin module base64. And since base64 is 'built-in' and I'm an awfull newbie, I can not guess what is v, decodestring, and base64 do(Obviously, 'v' get name & password for authentication). Ansorry situation. I wish Guido had implemented base64 in python not in C. .... So if anybody knows what v does with what kind of data reveal his sacred knowledge, I'd like to write a python bits to solve this problem(for those with non-ascii character names). I suggest this will be the 1st step for internalization of Zope(though only two guy from Chech & France and me seems interested in that). Quite weeks ago, I did some ugly hack to circumvent a id checking method to be able to add object whose id is composed of non-ascii characters. For IE and Netscape Korean version, there was no problem with that hack. But now I abandoned it, 'cause it's non-standard to use non-ascii chars in URL(very sorry situation though :(. But user's name is not a object id but a part of qurry string. So it seems(at least to me) not a violation of the standard. Being able to type in one's own name in his or her own language is very^3 user-friendly, don't you think so? for Zopal revelation, LEE Kwan Soo.

Zope and Emacs...
by David Brown 08 Feb '99

08 Feb '99

In the hopes that I will put an idea in someone's head, it should be fairly easy to come up with a "Zope mode" in Emacs that would grab the pages you want to manage using HTTP, providing the correct headers for validation and the like. Maybe even adapt the Emacs Web browser to do part of the dirty work. Sure would be better than using text areas. dave (who wishes he knew enough elisp to do the job)

zope on mklinux installation problems
by ben moretti 08 Feb '99

08 Feb '99

Howdy, I've installed Zope on mkLinux running on a PowerMac 8500 (a world first?) but encountered problems which will hopefully be transparently obvious I did the usual gunzip and tar stuff, and then ran the .py script to install the python HTTP server as root, and then ran the serve.sh script under my own account. All of the permissions for ./var were ok. I ran the kfm "web browser" under KDE (Netscape is not out for mkLinux!!) and accessed http://localhost:1234/manage I cannot remember the actual port number but it was the correct one in the Zope doco. I got a "cannot find file, does not exist or permission denied" error. The permissions were ok as I said, and python was running, etc. In fact, when I accessed http://localhost:1234 I got a page returned which does not seem consistent Any help?

Tree tag requires password??
by Fitzgerald Steele, Jr. 08 Feb '99

08 Feb '99

Hello... I'm trying to add a tree tag to a folder. I haven't defined any users or anything like that, so I expected the folder to inherit security attributes from the parent (the root dir, in this case, which is also user free). If I include the tree tag, Zope asks for authentication. If I  the tree tag out, it no longer asks for a user/pass. That's not the way its supposed to behave, is it? Is it possible to use the tree tag, without a password?  <a href=""> <img src ="/" border = 0>  </a>  See...nothing tricky... Thanks! Jerry

Still having problems !
by Richard Cramer 07 Feb '99

07 Feb '99

Hello to the list, Still have a problem trying to make Zope run. Specifically, HTTPServer is running OK, but if you go to the "manage" page, "sorry, serious application error" is displayed in both frames. I am using Python 1.5.1. Everything including the tk/tcl was built from scratch using the ports on FreeBSD v2.2.8. I have a Linux Redhat machine available to me where it was already loaded. Everything seems to be the same... I even make the var directory and access file permissions the same, but no joy. When you "edit frame set" under Netscape 4.5 the message is "management interfaces require a frame-capable browser". When I however point it a the Linux implementation it works perfectly. The linux implementation has an additional directory, python1.5, under lib where the FreeBSD port does not. The additional difference was that Linux implementation was under /usr/local/ where on the FreeBSD machine I installed in my directory. I would certainly welcome some pointer or suggestions from somebody that has gone thru this. TIA Dick -- Richard Cramer rcramer(a)sytex.net Phone: 703-425-2515 SytexNet(tm) Sytex Access Ltd.

Re: [Zope] Zope in Virtual Host on ISP
by Chris Larson 07 Feb '99

07 Feb '99

I thought I'd just kinda restate my problem from the ground up. Problem: Executing scripts through a Python other than the primary install on my ISPs machine. Conditions: 1. ISP has Python 1.4 installed at /usr/bin. 2. ISP has PyApache 2.25 compiled into Apache server for my domain (Virtual Host). 3. I have installed Python 1.5.2b2 into my home directory. (/home/c/change/local, with bin, lib, etc as it should be. 4. At command line, scripts execute correctly through my Python (I've set path to /home/c/change/local/bin:/usr/bin, etcetera (My notation, not literally "/etcetera" <grin>), so it finds the correct Python, executes environment script and returns everything correctly. 5. When executed through browser (through the Apache server, that is), no matter what I do, Python is either executed from /usr/bin or returns Internal Server Error. (I've tried explicitly stating absolute path to /home/c/change/local/bin/python, /usr/bin/env python, and for confirmation that tthe script is working, /usr/bin/python.) 6. I've also tried installing python in a local/ hierarchy in my cgi-bin and in my htdocs directories. (On a side note, if I could get one of these to work, should I worry about any security issues? They're both deleted now.) 7. I've tried directing python to execute through shell scripts as both .sh and .cgi, setting such paths and other environment variables as I thought prudent. The best I could accomplish was to get python to print (generate to the browser) the text within the '---' below, bypassing the Server Error by including an echo or two before calling python: --- Content-type: text/html </pre> Importing sys Done Importing sys Importing os --- I broke 'import sys,os' into two lines with print flags before and after because with just that line, all I got was: --- Content-type: text/html </pre> --- What I suspect this means is that the wrong python launched with the right sys.path. (Translation: Right: 1.5.2b2 in /home/... Wrong: 1.4 in /usr/...) If I add a 'print "Python %s" % sys.version' following sys import, I get: --- Importing sys Done Importing sys Python 1.4 (Feb 4 1997) [GCC 2.7.2.1] Importing os --- Summary: So, in a nutshell, I'm running in a 'virtual host' environment Apache with the PyApache 2.25 module compiled in. Apache does execute as my username. Apache does not seem to allow me to bypass PyApache (?) _or_ it won't consider (executable) paths not explicitly set somehow, even if executed as username through a shell. No matter where I try to direct execution, I end up with Python 1.4. (Now, This'll sound wonderfully naive, I'm sure, but my scripts to date have executed as #!sh, and the user shell variable used/set by Apache is csh. From all I understand, this should be irrelevant, but I wanna be sure. At this point, I'm rethinking everything I know about unix (linux) (which ain't all _that_ much, but I _had_ thought it was more than I'm realizing). Forgive if I seem to be rambling or missing the obvious. It's difficult to convey the level of my frustration in ascii. I've gone as far as setting 3 scripts calling each other before asking for python. At the moment, I have the two mentioned in Jeff's email (And thanks _again_ for all the help, Jeff!) running, with the added ...PYTHON variables to save typing between experiments. The current versions are listed below. Note that testcgi.cgi declares no #! I'm probably leaving out all sortsa relevant stuff, and/or missing something glaringly obvious, but hey, I'm tired, frustrated and kinda loopy at this point <grin>.
