Mark Pilgrim's Feed Parser in Zope

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

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. What am I doing wrong? Complete code and complete errors follow. Thanks.

Script execute with every request
by Joshua Burvill 25 Jul '06

25 Jul '06

Hi, I’d like to log certain parts of each request into a database table for every request to provide an audit trail. I thought of inserting a <dtml-call xxx> into the standard_html_header, but when there is a RESPONSE.redirect, it will not be the original request that gets logged. Can anyone offer any suggestions? Thanks, Josh -- No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.1.394 / Virus Database: 268.10.1/391 - Release Date: 18/07/2006

variable propagation
by Pavel Zaitsev 24 Jul '06

24 Jul '06

Hi, I would like to ask how to propagate variables from initial index_html call to deeper levels. Say I have index_html python script, I invoke it then I would like to feed some data to "generic" template, that will in turn will invoke template in the same directory that will do nice layout of my results. Generic template lies below all other objects, in directory tree, in the root. When I execute the command chain, variables are not passed and options is lost on one layer of zpt calls. Is there way to rectify that. Thanks Pavel

accessing object from a list constructed in __init__.py
by kevin7kal 24 Jul '06

24 Jul '06

I'm doing some work with Five and have an aquisition related issue. first, zope is zope 2.9.3 The trouble is with accessing the attributes of objects stored in the number property in class2. accessing class1.number via class2.method1a is no problem, the problem seems to stem from constructing a list of objects ala class2.__init__, if I try to append obj.__of__ in attribute1a I recieve an error that I can not pickle a wrapped class. Is there some other trick with acquisition to be able to access the attributes of an object which is stored in a list of object constructed in the __init__ function of a class? --myClass.py import Acquisition class class1(Acquisition.Explicit): ''' a simple class with some attributes and methods''' attribute1 = 'attribute 1' attribute2 = 'attribute 2' _number = '' def __init__(self,number2): '''simple init for the class''' self._number=number2*3 def method1(self): '''return a string methd1''' mthd1 = 'methd1' return mthd1 def method2(self): ''' return a string methd2''' mthd2 = 'method2' return mthd2 def _get_number(self): return self._number number = property(fget=_get_number) class class2(object): ''' a second simple class with some attributes and methods''' attribute1a = [] attribute2a = [] def __init__(self): '''create a list of class1 objects in attribute1a''' i=1 while i < 5: obj = class1(i) self.attribute1a.append(obj) i=i+1 def method1a(self): '''instantiate class1 as object and return object usable by zope''' obj = class1(5) return obj.__of__(self) def method2a(self): '''returns class1.method1()''' c1m1 = class1.method1() return c1m1 attribute1b = property(fget=method1a) attribute2b = property(fget=method2a)

by Tres Seaver 24 Jul '06

24 Jul '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Zope 2.8.8 Released On behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.8. You can download the sources from "http://www.zope.org/Products/Zope/2.8.8/", http://www.zope.org/Products/Zope/2.8.8 This bugfix release corrects the information exposure vulnerability addressed in the "2007/07/05 Hotfix.", http://www.zope.org/Products/Zope/Hotfix-2006-07-05 You may remove that hotvix product from your instances after upgrading to this version of Zope. New features of Zope 2.8.x - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) More Information For more information on what is new in this release, see the CHANGES.txt files for the release: "http://www.zope.org/Products/Zope/2.8.8/CHANGES.txt", http://www.zope.org/Products/Zope/2.8.8/CHANGES.txt See also: "http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView" http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: "http://www.plope.com/Books/2_7Edition/InstallingZope.stx", http://www.plope.com/Books/2_7Edition/InstallingZope.stx Reporting Bugs Please report all the bugs you have found to the Zope bugtracker: "http://collector.zope.org/Zope", http://collector.zope.org/Zope Supported Python versions At this time the only **supported** and **recommended** Python versions are 2.3.4 and 2.3.5. Using Python 2.4.X is **not supported** and **not recommended** at this time. Python 2.4.X will be supported when a security audit takes place. This means that you are using Python 2.4 + Zope 2.8 at **your own risk**. This warning also applies to binary packages that install Zope packages together with a system wide Python 2.4 installation (e.g. Fedora, SuSE...). Such installations are in general not supported. In addition there some third-party products and Python packages that don't work with Python 2.4 and can cause trouble when using Python 2.4. - -- =================================================================== Tres Seaver +1 202-558-7113 tseaver(a)palladion.com Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEuB0F+gerLs4ltQ4RAqO8AJ9ge1c1RDyOaZl7zoLr5aZcMCLI/wCfSbD3 xGCnKstYw313BIOeJ/QMzDs= =5LeI -----END PGP SIGNATURE-----
