ATFolder Annotations on Plone, could not find adapter on Windows
by Mikel Larreategi 11 May '07

11 May '07

Hi: I have Plone 2.5.2 installed on Zope 2.9.5 in two different machines. The first one is my Ubuntu box and the other one is a Windows server. I've created a custom content-type that basically inherits from ATFolder (Products.ATContentTypes.content.folder.ATFolder). After our zope3 training at Chappel Hill with Phillip, I'm trying to do my developments in a "Zope3-style", so I decided to store some data as an annotation of this objects. So, I mark my class with IAttributeAnnotatable, and when I try to adapt my object to IAnnotations to get or set the annotations, it works on my Linux but not on Windows. If I go to the ZMI and check this object's Interfaces tab (www.myserver.com/myobject/manage_interfaces) I can see that IAttributeAnnotatable is in the interface list of the object, but Zope fails to find the adapter. I've added a pdb.set_trace() in my annotation accessing view, and debugged it using runzope.bat but I'm still getting 'Could not adapt' error. I paste the debugging session: (Pdb) l 80 def __call__(self, *args, **kwargs): 81 context = aq_inner(self.context) 82 import pdb; pdb.set_trace() 83 try: 84 adapted = IAnnotations(context) 85 except: 86 from zope.app.annotation.interfaces import IAttributeAnnotatable 87 data = IAttributeAnnotatable.providedBy(context) 88 return str(data) 89 90 return adapted.get(self.ANNOTATION_KEY, '') (Pdb) context <MUSubSite at /mu/subgep> (Pdb) from zope.app.annotation.interfaces import IAttributeAnnotatable as ii (Pdb) from zope.app.annotation.interfaces import IAnnotations (Pdb) ii.providedBy(context) True (Pdb) IAnnotations(context) *** Type Error: ('Could not adapt', <MUSubSite at /mu/subgep>, <InterfaceClass zope.app.annotation.interfaces.IAnnotations>) (Pdb) Firstly, I thought that perhaps there was some nasty Acquisition issue here, so I tried with self.context (without the aq_inner thing), but it also fails: (Pdb) ii.providedBy(self.context) True (Pdb) IAnnotations(self.context) *** Type Error: ('Could not adapt', <MUSubSite at /mu/subgep>, <InterfaceClass zope.app.annotation.interfaces.IAnnotations>) (Pdb) In my Linux box, everything works great: (Pdb) context <MUSubSite at /mu/eps> (Pdb) self.context <MUSubSite at /mu/eps> (Pdb) from zope.app.annotation.interfaces import IAnnotations (Pdb) from zope.app.annotation.interfaces import IAttributeAnnotatable as ii (Pdb) ii.providedBy(context) True (Pdb) ii.providedBy(self.context) True (Pdb) IAnnotations(context) {} (Pdb) IAnnotations(self.context) {} Any hint will be appreciated, Best regards, Mikel Larreategi -- Mikel Larreategi mlarreategi(a)codesyntax.com CodeSyntax Azitaingo Industrialdea 3 K E-20600 Eibar Tel: (+34) 943 82 17 80

How to add properties? No Add button visible
by CSB 10 May '07

10 May '07

I am unable to Add properties. When I look at the Zope book, there is an Add button available, but I don't see that in my environment. For example. under the root folder, properties tab, I have a Save Changes button, but no Add or Delete buttons. Does anyone have any suggestions as to why this is the case? Zope 2.8.7 Regards Cameron

This makes mxODBC the ideal basis for writing cross-platform database programs and utilities in Python. mxODBC is included in the eGenix.com mxODBC Distribution for Python, a commercial part of the eGenix.com mx Extension Series, a collection of professional quality software tools which enhance Python's usability in many important areas such as ODBC database connectivity, fast text processing, date/time processing and web site programming. The package has proven its stability and usefulness in many mission critical applications and various commercial settings all around the world. * About Python: Python is an object-oriented Open Source programming language which runs on all modern platforms (http://www.python.org/) By integrating ease-of-use, clarity in coding, enterprise application connectivity and rapid application design, Python establishes an ideal programming platform for todays IT challenges. * About eGenix: eGenix is a consulting and software product company focused on providing professional quality services and products to Python users and developers (http://www.egenix.com/) ________________________________________________________________________ NEWS mxODBC 3.0 has received a large number of enhancements and supports more ODBC drivers than ever. Some highlights: * mxODBC has been ported to Python 2.5. * We've worked a lot on the Unicode support and made it more robust, especially on Unix platforms where the ODBC Unicode support has stabilized over the last few years. You can now issue commands using Unicode and exchange Unicode data with the database in various configurable ways. * We've also added a methods to give you more control of the connections and cursors as well as the .callproc() method for calling stored procedures that mxODBC 2.0 was missing. * Multiple result sets via the .nextset() are also supported, so working with stored procedures should be a lot easier now. * Another highlight is the added support for Python's datetime module types and the option to use strings for date/time processing (e.g. to be able to use timezones in timestamps if that's supported by the database). * Python's decimal module is now supported as well and it's possible to configure mxODBC to return Decimal types for numeric values. * mxODBC 3.0 received full 64-bit support, so that you can run mxODBC (and all other mx Extensions) on e.g. AMD64 platforms. * We've switched from the old distutils wininst installer to the new MSI installer for the Windows Python 2.5 build. This gives you a lot more options for automatic installs, including unattended installs. See http://www.python.org/download/releases/2.5/msi/ for details. Note that in order to avoid confusion, we've decided to rename the eGenix.com mx Commercial Distribution to eGenix.com mxODBC Distribution with this release. The commercial distribution has always only contained the mxODBC package, so this was an obvious step to clarify things for our users. As always we are providing pre-compiled versions of the package for Windows, Linux, Mac OS X, FreeBSD and Solaris as well as sources which allow you to install the package on all other supported platforms. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing the package can be found at: http://www.egenix.com/products/python/mxODBC/ IMPORTANT: In order to use the eGenix mx Commercial package you will first need to install the eGenix mx Base package which can be downloaded from here: http://www.egenix.com/products/python/mxBase/ ________________________________________________________________________ UPGRADING Please note that mxODBC 2.0 does not support Python 2.5 on 64-bit platforms due to the Py_ssize_t changes in the Python C API. You are encouraged to upgrade to the new mxODBC 3.0 release, if you plan to deploy on 64-bit platforms and use Python 2.5 as basis for your applications. ________________________________________________________________________ LICENSES & COSTS This release brings you all the new features and enhancements in mxODBC that were previously only available in through our mxODBC Zope Database Adapter. Like the Zope product, mxODBC now requires that you install a license in order to use it. You can request 30-day evaluation licenses by writing to sales(a)egenix.com, stating your name (or the name of the company) and the number of eval licenses that you need.

Upgrade woes: BTreeFolder --> BTreeFolder2
by Ken Ara 10 May '07

10 May '07

I have a couple of outstanding issues following an otherwise successful upgrade from Zope 2.7.4 to 2.10.3-final. One key application used the old DocumentLibrary product (http://www.zope.org/Members/Kaivo/DocumentLibrary) I have since reimplemented most of the functionality and migrated out the content, but I am unable to delete the old instances of the 'DocumentStore' class. This class is based on the old BTreeFolder which, as far as I can tell, cannot be be used in current versions of Zope. Starting Zope with the old BTreeFolder fails: Traceback (most recent call last): File "/usr/local/zope/lib/python/OFS/Application.py", line 703, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/zope/client0/Products/BTreeFolder/__init__.py", line 89, in ? import BTreeFolder File "/usr/local/zope/client0/Products/BTreeFolder/BTreeFolder.py", line 91, in ? from BTree import BTree ImportError: No module named BTree Swapping in BTreeFolder2 allowed me to access existing instances of DocumentLibrary, however attempting to delete the old instances of DocumentStore fails with the following error: Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module OFS.ObjectManager, line 524, in manage_delObjects Module OFS.ObjectManager, line 379, in _delObject Module zope.event, line 23, in notify Module zope.component.event, line 26, in dispatch Module zope.component._api, line 130, in subscribers Module zope.component.registry, line 290, in subscribers Module zope.interface.adapter, line 535, in subscribers Module zope.component.event, line 33, in objectEventNotify Module zope.component._api, line 130, in subscribers Module zope.component.registry, line 290, in subscribers Module zope.interface.adapter, line 535, in subscribers Module OFS.subscribers, line 108, in dispatchObjectWillBeMovedEvent Module zope.app.container.contained, line 181, in dispatchToSublocations Module OFS.subscribers, line 88, in sublocations Module Products.BTreeFolder2.BTreeFolder2, line 368, in objectValues Module Products.BTreeFolder2.BTreeFolder2, line 347, in objectIds AttributeError: 'NoneType' object has no attribute 'keys' If I could install the original BTreeFolder in Zope 2.10.3 - if only briefly - would that enable me to delete the old instances? Other ideas? Thanks, Ken __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

method call pre-attribute access
by Brian Brinegar 09 May '07

09 May '07

I've got product where it would be very beneficial to me if I could have a method called prior to any attribute access. For example: thing.foo thing.getProperty('foo') Either of these should trigger a call to a method which could allow or deny access to the attribute. Any thoughts? -- Brian Brinegar Web Systems Developer Engineering Computer Network

Re: [Zope] apache rewrite quit working
by Thomas Bennett 09 May '07

09 May '07

Don't think that is it because it works fine if I change Zope to port 80. And, I was accessing apache on port 80 using the ip number, localhost, the machine's real name, and the URL domain it just wouldn't rewrite to 8086. nslookup showed name was still set to my ip number.

how to change from folder to plone site
by bbxrider 08 May '07

08 May '07

not sure how it could have happened, musta been coworker, but my plone site 'root' got changed to a folder ie, 'folder at /' instead of 'plone site at /sitename' the site still serves up ok and zmi from site login is ok but zmi with zope login results in error if i try to access site folders, see following error Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: 1docs GET is there any way to change it back to plone site? i tried to copy the corrupted site in bulk to a new plone site, but none of the customization came across perhaps some export then import back to plone site w/diff name then rename? there are a fair amount of modifications to the default plone site bob
