z3c.sqlalchemy 1.0.0 released - Integration of SQLAlchemy with Zope 2/3
by Andreas Jung 05 May '07

05 May '07

I am pleased to announce the first public release of z3c.sqlalchemy V 1.0.0 What is z3c.sqlalchemy? ======================= z3c.sqlalchemy is yet another wrapper around SQLAlchemy. The functionality of the wrapper is basically focused on easy integration with Zope 2 and Zope 3. The wrapper cares about connection handling, optional transaction integration with Zope 2/3 and wrapper management (caching, introspection). z3c.sqlalchemy gives you flexible control over the mapper creation. Mapper classes can be - auto-generated (with or without autodetection of table relationships) - configured by the developer What z3c.sqlalchemy does not do and won't do: ============================================= - no support for Zope 3 schemas - no support for Archetypes schemas z3c.sqlachemy just tries to provide you with the basic functionalities you need to write SQLAlchemy-based applications with Zope 2/3. Higher-level functionalities like integration with Archetypes/Zope 3 schemas are subject to higher-level frameworks. z3c.sqlalchemy does not address these frameworks. Requirements: ============= - Zope 2.8+, Zope 3.X - SQLAlchemy 0.3.6 or higher Installation: ============= - either download z3c.sqlalchemy from Cheeseshop <http://cheeseshop.python.org/pypi/z3c.sqlalchemy/> - or use easy_install: easy_install z3c.sqlalchemy Andreas Jung -- ZOPYX Ltd. & Co.

modify 'Server' response header
by Jens-Erik Hansen 03 May '07

03 May '07

Hi, is there a way to control the 'Server' response header in ZServer like it could be done with the ServerTokens directive in apache? In an apache -> squid -> zope configuration I tried apache's mod_headers but this only works if the page is cached in the browser (304 Not Modified), a browser-reload for example reveals ZServer. Does anyone know how to accomplish this without modifying any zope code? Thanks Jens

Late binding
by Garito 03 May '07

03 May '07

Hi all! In this function: def ProcesarTALES(self, expresion, args = None): if expresion is None: return None engine = getEngine() contextoTALES = {'container': self.aq_parent, 'here': self, 'context': self, 'request': self.REQUEST, 'options': {}, 'sitio': self.Sitio(), 'user': getSecurityManager().getUser(), 'entidad': self.Entidad()} if args is not None: contextoTALES['options'] = {'args': args} resultado = engine.getContext(contextoTALES).evaluate(engine.compile (expresion)) return resultado is possible that the execution of entidad (self.Entidad()) has launched at evaluation time not at assign time? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito

Unicode charset problems dealing with the ZmySQLDA product
by Miguel Sánchez Beato 30 Apr '07

30 Apr '07

Hello. I'm dealing with the ZmySQLDA product on Zope 2.9.7 and Python 2.4.3 versions. I'm having problems when I retrieve data from the database because the data is not rendered using the unicode charset when the zope instance is in a vserver (with a Gentoo Linux distribution), so I get weird characters like 'Ã¡' instead of the usual ones: 'á' (as they are strored inthe db). This is not happening on my local machine, so I guess it could be a bad configuration of the vserver. Is there any possibilities to pass a parameter to the ZmySQLDSA connection to make it use the unicode charset? Which differences are between the _mysql python module and the MySQLdb library for this purpose? Could it be the configuation of the vserver? How can it be relationed with the unicode problems? Any idea? Thanks!!

External Editor Doesn't Work with Firefox
by Ken Winter 30 Apr '07

30 Apr '07

I have External Editor (zopeedit-win32-0.9.3.exe <http://www.plope.com/software/ExternalEditor/zopeedit-win32-0.9.3.exe> ) installed on my WinXP machine. It works fine with my IE6 browser. But with Firefox 2.0, it doesn't. Specifically, with the ZMI running in Firefox, what happens is: 1. I get the stubby pencil icons on editable Zope objects. 2. Clicking on the stubby pencils brings up that page in my selected external editor (currently Dreamweaver, but I have tried this with other tools and the results are the same). So far, so good. 3. But when I save changes from the external editor, the changes don't make it back into Zope, and they don't show up on the rendered pages. a. The changes do show up in the temp file that the external editor saves to. So the problem is not with the external editor's file saving abilities. b. No error messages occur. c. So the problem must be that the EE helper app is not picking up the changes, or is not getting them back to Firefox. My hunch is that I have failed to execute the following step in the External Editor's Windows installation instructions (http://www.plope.com/software/ExternalEditor/install-win32) "You can also register it (zopeedit.exe) with other browsers directly." The reason I haven't done this step is that I can't figure out how to register a helper app in Firefox. After a lot of Googling etc, I'm still stuck. The only clue (or not) I have to offer is that the file "C:\Documents and Settings\Ken\Application Data\Mozilla\Firefox\Profiles\uhpuzmf9.default\mimeTypes.rdf", which apparently is the operative Firefox configuration file, has these relevant (?) entries: <RDF:Description RDF:about="urn:mimetype:externalApplication:application/x-zope-edit" NC:path="C:\Program Files\Macromedia\Dreamweaver MX\Dreamweaver.exe" NC:prettyName="Dreamweaver.exe" /> <RDF:Description RDF:about="urn:mimetype:handler:application/x-zope-edit" NC:alwaysAsk="false" NC:saveToDisk="false" NC:useSystemDefault="false" NC:handleInternal="false"> <NC:externalApplication RDF:resource="urn:mimetype:externalApplication:application/x-zope-edit"/> </RDF:Description> <RDF:Description RDF:about="urn:mimetype:application/x-zope-edit" NC:description="" NC:value="application/x-zope-edit" NC:editable="true"> <NC:handlerProp RDF:resource="urn:mimetype:handler:application/x-zope-edit"/> </RDF:Description> <RDF:li RDF:resource="urn:mimetype:application/x-zope-edit"/> ~ TIA ~ Ken

RE: Problem Getting dtml-with to work
by Mark, Jonathan (Integic) 30 Apr '07

30 Apr '07

Thanks to the other Jonathan for advising me to try <dtml-in objectIDs> to find why dtml-with was not working as expected with FolderB. When I did that I realized that FolderB was not an actual folder. Rather, it was a Plone instance. One cannot not use <dtml-with> from outside a Plone instance to call up an object inside a plone instance. Therefore I solved my problem in another way using Response.redirect().
