Zope import PythonScript.standard unauthorized

Hi, I've just insalled Zope to test a web application by thirdy part .... well .... it's very embarrassing cause I'm not able to see it to work because of Zope ..... (yeah... I'm really newbie :( ) I found out that the problem is in Products/PythonScript permission. To test them, in the ZMI, I created this script and then I tested it ============================================== TEST SCRIPT ============================================== # Example code: from Products.PythonScripts.standard import html_quote, urlencode return 1 ============================================== TEST OUTPUT ============================================== Zope has encountered an error while publishing this resource. Error Type: ImportError Error Value: import of "urlencode" from "Products.PythonScripts.standard" is unauthorized In Zope Bible they say there is a trick to escape this control using "External Methods", but it should be another way because the application I have to test doesn't use them at all ... any useful suggestion ..........? I'm using on Debian Woody Zope = Zope 2.5.1 Python= 2.1.3 Thank you very Lucas

dynamically generate dtml-tree urlparam attribute?
by jason 11 Dec '03

11 Dec '03

hi, i was wondering if anyone has either hacked the dtml-tree code or written a python script to create a <dtml-tree> tag with a dynamically generated urlparam attribute? i currently have a <dtml-if/elif/else> that selects from 7 prewritten <dtml-tree> tags, but i was hoping there was a better/slightly more elegant way of doing this. -jason yee

Help on identification
by Tiller, Michael (M.M.) 11 Dec '03

11 Dec '03

I've tried looking through all the available user folder types and I'm still not sure I understand which one is best for me. Here is my situation: I'm trying to setup a Zope server on our corporate intRAnet set. We have a formal system of authenticating users. It is centralized. I don't want to go into too much detail, but suffice it to say that I can invoke a program and it will tell me whether the person requesting my page has a valid certificate and, if so, who the person is. What is the best scheme for integrating such a program into the Zope authentication and identification process. Key things are: 1) The user does not provide a password, only the validity of the certificate is checked. 2) How do I invoke an external program from Zope?!? 3) Are there any "out-of-the-box" user folders that can handle this? I couldn't find any. If not, what is the best open ended product and what would I need to do? Thanks for any help. -- Mike

ANN: eGenix mxODBC Zope Database Adapter
by M.-A. Lemburg 11 Dec '03

11 Dec '03

________________________________________________________________________ ANNOUNCEMENT EGENIX.COM mxODBC Zope Database Adapter Version 1.0.7 Available for Zope 2.3 through 2.7 on Windows, Linux, Solaris and FreeBSD ________________________________________________________________________ INTRODUCTION The eGenix mxODBC Zope Database Adapter (Zope DA) allows you to easily connect your Zope installation to just about any database backend on the market today, giving you the reliability of the commercially supported eGenix.com product mxODBC and the flexibility of the ODBC standard as middle-tier architecture. Unlike Zope's ZODBC Zope DA, the mxODBC Zope DA works on Windows XP/NT/2000/98, Linux, Solaris and FreeBSD using the same interface on all platforms. The mxODBC Zope DA implements high performance thread-safe connection pooling and multiple physical connects per logical Zope connection. You can safely run Z SQL Methods in parallel, achieving a much better throughput than ZODBC Zope DA or similar Zope database adapters under heavy load. This makes it ideal for deployment in ZEO Clusters and Zope hosting environments where stability and high performance are a top priority. ________________________________________________________________________ FEATURES * Zope Level 3 Database Adapter: the mxODBC Zope DA is fully multi-threaded and can handle multiple connections to multiple databases. * Fully compatible to Z SQL Methods. * Drop-in compatible to the ZODBC DA: the mxODBC Zope DA provides the same interfaces as Zope's ZODBC DA to allow a smooth upgrade path from this simplistic adapater to the high performance mxODBC Zope DA. * Fully compatible to the Znolk SQL Wizard Product and other similar products relying on the common database schema access methods .tables() and .columns(). * Connection Pooling: physical database connections are pooled and kept open, to reduce the connection overhead to a minimum. This is especially important for high latency database connections and ones like Oracle which take a considerable amount of time to setup * Parallel Execution of Queries on a single logical connection: the mxODBC Zope DA can manage any number of physical connections on a single logical connection. This enables running truly parallel Z SQL Method queries -- a feature not available in other Zope DAs. * Robust Mode of Operation: connections which have timed out or go away due to network problems are automatically reconnected. * Cross-platform Connection Objects: The Zope DA will automatically choose the right platform specific ODBC manager for you. * Per Connection Adjustable ODBC Interface: mxODBC comes with many different subpackages to choose from on Unix. The Zope DA allows you to select these subpackages on a per-connection basis. * Per Connection Error Handling: you can tell each connection whether it should report ODBC warnings or not; furthermore all warnings and errors are made available as list .messages on the DatabaseConnection object. * Transaction safe automatic reconnect: when the DA finds that a connection has timed out, it automatically tries a reconnect and replays the transaction on the connection (unlike other DAs which break the transaction scheme by doing a reconnect without replay). * Built-in Schema Cache: this results in improved performance under heavy load. * Database Schema Access: all ODBC catalog methods are made available for much better database schema inquiry. The catalog methods allow building generic database interrogation or manipulation tools and facilitates writing database independent Zope products. * Lazy Connect: the mxODBC Zope DA only connects to the database backends when a connection is actually requested. This results in a better use of resources compared to other Zope DAs. ________________________________________________________________________ NEWS Version 1.0.7 includes the following changes and enhancements: * Zope 2.7.0 and Python 2.3 are now fully supported. * The connection pooling was made more robust to allow less capable ODBC drivers to work nicely with the mxODBC Zope DA. * A new option was introduced to let the mxODBC Zope DA return empty strings instead of None for SQL NULL values. This should simplify porting applications to the mxODBC Zope DA. * A problem with the MS SQL Server was solved which caused deadlocks under heavy load in some application settings. In short: mxODBC Zope DA is continuing to become the number one solution for integrating relational databases with Zope applications. ________________________________________________________________________ UPGRADING If you have already bought mxODBC Zope DA licenses, you can use these license for the updated version as well. There is no need to buy new licenses. The same is true for evaluation license users. ________________________________________________________________________ MORE INFORMATION For more information on the mxODBC Zope DA, licensing and download instructions, please visit our web-site: http://www.egenix.com/ You can buy mxODBC Zope DA licenses online from the eGenix.com shop at: http://shop.egenix.com/ ________________________________________________________________________ Thank you, -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Dec 11 2003) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! ::::

Hello, Just tried to run zope under Suse 9.0 and had the problem to log in. After following the previous discussion on this subject I managed to log in after the following changes: The file 'inituser' in /opt/zope is owned by root:root with only rw access rights for the owner. chmod go+r /opt/zope/inituser rm /opt/zope/var/Data.fs restart zope Open localhost:8080/manage I was able to log in with 'superuser' and '123'.

tal+zclasses
by Henny van der Linde 11 Dec '03

11 Dec '03

Hi, Till now I did everything with dtml, external python scripts, python scripts and zclasses. Gradualy I want to switch over to pagetemplates and external python products. The first thing I want to do is converting the dtml to pagetemplates in the actual sites. These sites are based on a lot of Zclasses. For instance: <dtml-with batest> <dtml-var index_html> </dtml-with> Where batest is an instance of a basic element of our content management system. After reading zpt docs (Zopebook and docs on devshed), searching in the mailing list archives I came to the following equivalent: <tr><td tal:define="batest here/batest" tal:content="batest/index_html"></td></tr> This only works in the way that it can find the index_html method (dtml) in the Zclass batest is an instance of. It won't render (it won't find) the other dtml-methods or any other object in the Zclass wich the index_html calls. So how do I do a 'dtml-with' in tal? Henny
