Uh, help?! No-one has answered this yet. Perhaps it's so trivial everyone's waiting for someone else to do this? I really need an answer!

HowTo call a Python Method from DTML-Document
by hans 04 Oct '01

04 Oct '01

on Zope 2.1.6 (python 1.5.2) ==> Python Method Check # no parameters, should check REQUEST.form # and for each checked form-field add a corresponding # diagnostic data = REQUEST.form diag = {} diagnose = 1 # erverything ok if data['fname' ] == '': # required diag.set('fname' , 'required' ) diagnose = 0 ==> DTML-Document Form calls <dtml-call "Check( ... )"> 1) this is not documented in Zope Book Appendix B (calling DTML-Docs & DTML-Methods is documented well) 2) i tried various parameters (the "..."), none of which works 2a) no actual parameters, no formal parameters: obviously, cant reach REQUEST, since zope complains >>nonexistent object or variable REQUEST. >>Info( (), {}, None ) 2b): giving Check formal Parameter REQ, call Check( REQUEST) results in REQ=the html-string delivered from REQUEST.__call__ (the same as <dtml-var REQUEST>) and a string sure has no attribute "set"...

Runtime error in python scripts
by Harris Peter 04 Oct '01

04 Oct '01

Hi I just got a query from someone testing my Zope application "f2w helpdesk" (on sourceforge). They got an error in a Python Script: Error Type: RuntimeError Error Value: Script (Python) task_originator_phone has errors. with the following traceback: -------------------------------------------- Traceback (innermost last): File /usr/lib/python2.1/site-packages/ZPublisher/Publish.py, line 223, in publish_module [snip... the usual stuff ] (Object: edit_open_request) File /usr/lib/python2.1/site-packages/DocumentTemplate/DT_Util.py, line 231, in eval (Object: task_originator_phone(r_originator)) (Info: task_originator_phone) File <string>, line 2, in f File /usr/share/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: task_originator_phone) File /usr/share/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: task_originator_phone) File /usr/share/zope/lib/python/Products/PythonScripts/PythonScript.py, line 354, in _exec (Object: task_originator_phone) (Info: ({'script': <PythonScript instance at 88b7548>, 'context': <r instance at 88ce2f0>, 'container': <Folder instance at 8829200>, 'traverse_subpath': []}, ('OPSC',), {}, ())) RuntimeError: (see above) ---------------------------------- They are clearly using Python 2.1, and hence Zope 2.4. I am using Zope 2.3.3 on Debian, and I can't duplicate the error myself. What I am asking is, have there been any incompatible changes between Zope 2.3 and Zope 2.4 in the syntax or handling of Python scripts? The script is as follows, in case it gives any clues. ## Script (Python) "task_originator_phone" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=r_originator ##title= ## results = context.sel_k_1(k_id=r_originator) contact = results and results[0] # None if no results, first row if there are any visible = "" # The text to appear on the page title = "" # The title text (hover help, on some Browsers) if contact: if contact.k_ext: visible = contact.k_ext + " " + contact.k_location # Prefer ext and location title = contact.k_phone_1 or contact.k_phone_2 # help is a phone number else: visible = contact.k_phone_1 or contact.k_phone_2 # settle for a phone number if visible: return '%s' % (title,visible) else: return "" ---------- I will be grateful for any clues as to what I can do to make my scripts compatible with both versions of Zope, if that is indeed the problem. If the problem is I've done something stupid, please someone let me know about that too :) Peter Harris **************************************************************************** This message and any files transmitted with it are confidential.

Distro Views from a relative Newbie
by Chris Keyes 04 Oct '01

04 Oct '01

Hi all Just figured I should add my views to the discussion about distrobutions and stuff I've used SuSE, RedHat, Debian and we also have Mandrake installs here at NIP... And from what I can tell its more of a matter of personal taste rather than specific reasions to use one or the other. Some tend to install a lot and aim to give you everything working, others install less and let you add what you need, but then, you can always customise what you need when your up and running... I've had some problems on Debian with Zope 2.1 and Zope 2.1.1 where the expat parser is not installed by default (although it seems to be on Windoze and RedHat)... From my discussions here it would seem that I needed to install some Debian packages to get it to work, but in the end the PyXML product sorted that... Generally we use the source installs of both Python and Zope... And they are pretty painless. Installing python2.1 as the default on a machine has caused issues where none zope related scripts and so on ending up broken... but doing a make altinstall when installing python and then linking python2.1 to python2.1 just means that new versions of python need a slightly modified start script pointing to python2.1 and when you compile stuff you need to remember which python you need to use (Zope helpfully tells you if you try and run 2.4 with an old version of python)... In terms of reliability and longterm pain free administration, particularly if your not the only one using the box you really need to sort out where things are to be installed and make sure that people stick to these! Also I believe having used them, that an instance home scheme is well worth the little bit of pain to get it up and running (remember to change the name of pythonhome to something else for 2.4 versions of zope - had me confused that one... :-)) Um, really I think the linux distrobution is not as relevant as how it is administered. Infact in may ways some of the basic text only installs may be more appropriate than the modern slick installers that are designed to get you up and running fast... In the end if it works :-) The other note I suppose is the regional thing, RedHat seems to have a hold in the USA and is fairly popular elsewhere... SuSE seems to be much more popular in Germany and so on... So I'm going to second Andrew Milton and say install what your most likely to get support with, if your mates run it then it only costs a pint (or whatever) to get it fixed!! Hope thats not all been said in the time it took me to write it... ChrisK

Small ZSyncer patch: added 'manage_sync' to URLs in 'Sync.dtml'
by Jean Jordaan 04 Oct '01

04 Oct '01

Hi Andy I've checked out ZSyncer from SourceForge CVS, and will be tinkering with it a bit. Currently, it isn't possible to browse back up the tree of directories in the 'manage_sync' view. The included patch fixes that. Specifically, the first thing I'm trying to do is to get a view presenting only the out-of-date objects recursively, so that I can see the changed objects in a whole tree in one go. Regards, & thanks for a very useful tool, Jean Index: dtml/Sync.dtml =================================================================== RCS file: /usr/local/upfront/repository/zope/ZSyncer/dtml/Sync.dtml,v retrieving revision 1.1 retrieving revision 1.2 diff -r1.1 -r1.2 29c29 < <a href="?">Root</a><br> --- > <a href="manage_sync?">Root</a><br> 34c34 < <a href="?folders=&dtml-old_folders;"><dtml-var sequence-item></a><br> --- > <a href="manage_sync?folders=&dtml-old_folders;"><dtml-var sequence-item></a><br> 117c117 < </HTML> \ No newline at end of file --- > </HTML>

Good newsgroup?
by Toh Wanda 04 Oct '01

04 Oct '01

Hi List! Although I do my best, I can't keep up with all those mails. Does anyone know a Zope-Newsgroup/Forum, which is good enough to replace this list (for me)? The short time I spent with you was very enlightening, thanks, Toh! _________________________________________________________________ Downloaden Sie MSN Explorer kostenlos unter http://explorer.msn.de/intl.asp

RE: [Zope] Use properties of a product?
by Lars Heber 04 Oct '01

OK, second try: > I am not sure I understand totally about your problem, but this is what I > think you want: > When the user has an addForm for that ZClass - you want a default value for > actual location? Yepp. > If this is the case - (AFAIK) you cannot access the property of the ZClass > instance until you have created it. Yes, that's clear. > Thus you will have to hard code your > default location into the addForm. That's what I wanted to avoid. What I want to use is a property "location" of the product AA, which contains the ZClass AAClass. In the addForm of that AAClass I'd like to use this "location" of the product AA, but not some property in the propertysheet of the ZClass to be created! >> OK, I have a product, lets say AA. It has a property location. >> Within this product, I have a ZClass.
