copying folder?
by vl 27 Jul '06

27 Jul '06

Is there a way to copy a folder on zope, nightly through a cron job and then rename it? I would think I could call lynx or wget from cron with a zope url but I don't know how I would go about doing it. Example of what I want to do: I have a folder in the root of zope called py_scripts I want to copy. Then I want to rename the copied folder py_scripts with today's date on the end of it. I would like cron to do this nightly for me. Any ideas? Thanks, Greg

ZJetDA product and Microsoft Access
by michael nt milne 27 Jul '06

27 Jul '06

Hi I've had a look at this product and installed it on Zope 2.8.7. It installed fine but when I look in the 'add' menu I'm not seeing an 'add ZJetDA database connection' which you get for other installed database adapters. Possibly I'm wrong in expecting this? I know it's totally crazy to want to hook Access up with Zope using sql queries but I'd just like to know if it's been done or is possible. Thanks -- michael

Hi, I am having trouble trying to get apache to use sub domains for my 2 instances of zope. I want test.server name for one sub domain adn live.server for the other. The first sub domain for test instance of zope. The second sub domain for the lvie instance of zope. Anyone done this before? Can you show me an example of apache config file? Thanks -- View this message in context: http://www.nabble.com/Running-2-instances-of-Zope-on-Apache-tf1998979.html#… Sent from the Zope - General forum at Nabble.com.

Mark Pilgrim's Feed Parser in Zope
by kjzz.webmaster＠riomail.maricopa.edu 27 Jul '06

27 Jul '06

I'm trying to move our sites from Zope 2.5.1 to Zope 2.8.1-final and I'm receiving an error with this script: http://www.zope.org/Members/johntynan/feedparser/ In particular, I receive the following error, when using the attached page template "nprnews.pt": "Unauthorized: You are not allowed to access 'a particular list' in this context" (see traceback.txt attached). This page template renders an rss feed that has been transformed into a dictionary (see "dictionary.txt" attached) via a python script ("feedscript") which calls an external method ("newsfeed") which uses Mark Pilgrim's feed parser to parse the xml into a python data type. If I run the python script or the external method directly (via the "test" tab in the ZMI) I have no problem viewing all the properties of the rss feed. However, if I use the page template, I still receive this error. I've tried to get around this by running the python script using a proxy role of manager or owner, but I still receive the same error. Any suggestions you might have are appreciated. John Tynan - webmaster KJZZ.org / KBAQ.org 480.774.8462

Accumulate vars with <dtml-var expr="...">
by Jesper Steen Steffensen 25 Jul '06

25 Jul '06

Hi all. I have a table with a list of values. To list my values in a dtml method i write <dtml-var value> inside the appropriate dtml-in tag. In the next column I have the <dtml-var sequence-number> This gives me something like: VALUE SEQNUMBER 13 1 10 2 11 3 10 4 12 5 ... I want to accumulate my values so the result will be: VALUE SEQNUMBER ACCU 13 1 56 10 2 43 11 3 33 10 4 22 12 5 12 ... Is it possible to make this accumulated value as a <dtml-var expr="[something like sum of values where seq-num <=seq-num]"> I can't do it in the ZSQL that gets the values, as the value field itself is a calculated value (can only do it on non-calc'd data). Any other non-SQL suggestions as to how this is achieved is highly appreciated! Thanks from Denmark Steff

DB in Zope
by Alan 25 Jul '06

25 Jul '06

Hi! I need a very simple DB in Zope, a table with 5 columns, less than 100 entries, to write, read and update, nothing else. Is Gadfly a serious option? Do l loose my database if Zope is restarted? Which other option, easy to use? A tutorial? Many thinks in advance.

Python/TAL Problem
by beno 25 Jul '06

25 Jul '06

Hi; I'm trying to tweak someone else' script to get it to do what I want. The script reads from and writes to the "Properties" tab of pages and folders, enabling one to change the titles of many pages/folders from one single script-generated page. I want to be able to do the same thing with another field I created called "KW1" (string) in the Properties tab. The following is a snip of the code that needs to be altered (the only code where "title" appears): <input type="text" name="rows.title:records" size="50" tal:attributes="value python:item['title']" /> <input type="hidden" name="prev_rows.title:records" tal:attributes="value item/title" /> If I alter line #2 and change "title" to "KW1" I get the following error snippet: * Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ __traceback_info__: item['KW1'] * Module Python expression "item['KW1']", line 1, in <expression> * Module AccessControl.ZopeGuards, line 67, in guarded_getitem If I alter line #4 and change "title" to "KW1" I get this error snippet: * Module Products.PageTemplates.Expressions, line 174, in __call__ * Module Products.PageTemplates.Expressions, line 162, in _eval * Module Products.PageTemplates.Expressions, line 116, in _eval __traceback_info__: item * Module Products.PageTemplates.Expressions, line 320, in restrictedTraverse __traceback_info__: {'path': ['KW1'], 'TraversalRequestNameStack': []} I have added KW1 as a string property to many of the pages in the target folder.
