You've got the string calling wrong. String.split() is a "builtin" python module for DTML. You call it by _.string.split() Besides... python syntax: '/'[-1] == '/'[0] == '/' == / Besides you haven't declare string as builtin with the _. <dtml-call "REQUEST.set('url_as_list',_.string.split(URL,'/'))"> Last objectid in URL: <dtml-var "url_as_list[-1]"> Or simpler: <dtml-var expr="_.string.split(URL,'/')[-1]"> ----- Original Message ----- From: "Junk" <junk(a)gargl.net> To: "Peter Bengtsson" <peter(a)grenna.net> Sent: Friday, March 23, 2001 6:57 PM Subject: RE: [Zope] url question... > > string.split(URL,'/')[-1] > > why can't i do <dtml-var expr="string.split(URL,'/'[-1])"> ??? > > junk >

web crawlers, robots & graphs / visualisation, zope-edu

Hi there everyone, I have heaps of questions... Can any one tell me if Web sites developed using Zope can be indexed on search engines like Google / AltaVista when those wee spider fellas visit the server..? -- Also, assuming the following is possible, what would be the best way to implement such a system (and what are the alternatives)? Background: My system facilitates the creation of student and class information databases, and holds records of students grade, attendance records, etc. The student can access this the system to retrieve their records and relevant statistics. Right now, those statistics are the max, min, median and standard deviation value for every piece of graded coursework. Problem: Is there anyway I can visualise this data? I have a few ideas - if you have any thoughts or comments, please feel welcome... 1 - A Java applet - this is the most attractive option but put your hands up if you say that you shouldn't use Zope with Java. 2 - I don't know much about Python's Tk/Tkinter - could I use that somehow? 3- I have thought about creating a big much of .GIFs. I could maybe process all the data and store the layout of the graph in a 2D array and then use these 2 plot a graph by inserting an appropriate .GIF on the page. This would be fun but it would take me years!!! 4- I've already seen that I can export my data to MS Excel. Is it possible to do this again but have the data displayed *directly* in a graph upon viewing the data? I severely doubt this is possible... 5- Great idea for a new zope product : Data visualisation & graph maker!!! ;-) Cheers for any help. Lee PS: Zope-edu folks, I've spoken to my project supervisor to see if I can donate my project to your SIG. don't know if you can use it - but it's got some good ideas. if anyone wants to see a demo drop me a line...

Dieter, Thank you! That was exactly what I was looking for! I can not believe I missed that one! Zope is such an amazing tool... with good documentation it would be superb and the book you are working on is helping it on its way (as well as all the tips you give to the list!). Keep up the good work! Carl P.S. By the way... after knowing what to look for I did find a Howto on local roles. ----- Original Message ----- From: "Dieter Maurer" <dieter(a)handshake.de> To: "Carl Blesius" <cblesius(a)ix.urz.uni-heidelberg.de> Cc: <zope(a)zope.org> Sent: Saturday, March 24, 2001 9:11 PM Subject: Re: [Zope] User_Management - Two Folders in different branches | Carl Blesius writes: | > Okay... lets say I have one folder | > | > /users/John_Doe/ | > | > with an acl_users folder in it with one | > user (John_Doe). | > | > After John_Doe knows his way around Zope | > well enough I am going to let him take | > over a branch of our website | > e.g. /clinics/pathology/ | Move "John_Doe" up enough such that everything, he should take over, | is below that point.

RE: [Zope] Broken Zope installation

Nope - this happens on a fresh install of 2.3.1b3 (but not on 2.3.0), with any (old/imported or new) PythonScript and any DTML method - see my second email (Bug in Zope2.3.1b3 PythonScripts) Thanks for the suggestion though :o) (I think you were right about the logging - an unrelated problem I suspect) Cheers, Phil -----Original Message----- From: Dieter Maurer To: Mayers, Philip J Cc: 'zope(a)zope.org' Sent: 24/03/01 20:34 Subject: Re: [Zope] Broken Zope installation Mayers, Philip J writes: > I appear to have a broken Zope installation.

I would install freshly, check that PythonScripts work correctly. Then move the old "var/Data.fs" to the new installation. Check again.

Hello all, I am trying to install zope on my PC using the Zope-2.3.1b3-src.tgz file. I am repeating what I did when I installed Zope-2.3.1b2-src.tgz. however now I run into a problem. When I run python wo_pcgi.py I get an error (see output below): ###BEGIN : : gcc -fpic -I../Components/ExtensionClass -O2 -m486 -I/usr/include/python2.0 -I/usr/include/python2.0 -DHAVE_CONFIG_H -c ./../Components/ExtensionClass/ExtensionClass.c gcc: Internal compiler error: program cc1 got fatal signal 11 make: *** [ExtensionClass.o] Error 1 Traceback (most recent call last): File "wo_pcgi.py", line 116, in ?

Adding Folders and index_html from Python Script
by complaw＠hal-pc.org 24 Mar '01

24 Mar '01

Okay, I'm trying to create a site where the users can load information about prospective clients and then add contact information about each client. This is how it works now... I have a form that creates a folder with the name of the client as the title of the folder. No sweat. I use... context.manage_addProduct['OFSP'].manage_addFolder(id=id, title=clientName) .. which works fine to make the folder itself. However, there is nothing in the folder (i.e., no index_html file). Thus, when the user moves to the folder, they get the index_html from the parent folder. Is there a way to add a file to the newly created folder from a Python script? The contents of the file can be very easy (such as "<dtml-var standard_html_header><dtml-var standard_html_footer>"). As an asisde, I want to make the id of the folder a string that contains only allowable characters that are taken from the name that the users input (with an _ used in place of the blanks). Is there a quick easy way to do that with some library function that isn't showing up in the Python Library Reference at www.python.org? Thanks in advance, Ron

Collecting objects according to type in folders is not very Zope friendly. It is much better to group all objects required for a (sub-)application (or task) together in a folder: organisation according to task rather than according to type! That said, you can use: <dtml-with SUBDIRECTORY> <dtml-var image> </dtml-with> Dieter

I thought that creating new Python scripts or changing old ones would fail with the indicated error. But, apparently, you can create and change but then the script no longer works. You may try to rename "dtml_method". Maybe, somehow your context finds the wrong one. > 2) Restart or Shutdown from the Control Panel link fail with an error 5 (I/O > error) - this only happens intermittently. Apparently, it wants to write somewhere, where it is not allowed to. When you analyse the traceback, you may see, what operation fails. Maybe, it wants to write on the terminal which has been closed meanwhile... Dieter
