Heads-up: Zope 2.8, Zope 3 and Five
by Brian Lloyd 15 Mar '05

15 Mar '05

Hi all - At the Paris sprint, a plan was hatched to integrate Five into Zope 2.8, which Jim, Andreas and others responsible for release management have endorsed. This will hopefully actually help spur 2.8 to the finish line as well as begin to provide an upgrade path into the future for Zope 2 developers. What this will essentially mean for is that: - Five will ship in the core distribution with Zope 2.8 - A subset of the Zope X3.0 packages will ship in the core distribution ...so it will be possible to use a number of Zope 3 technologies and patterns in existing Zope 2 applications. The Five integration layer provides support for Zope 3 interfaces, Zope Configuration Markup Language (ZCML), adapters, views, utilities, schema-driven content, and Zope 3 add and edit forms. Note that the Five layer does *not* attempt provide a ZMI user interface for Zope 3 components. Zope 2.8+ will include the essential Zope 3 packages, so it will not be necessary to install Zope 3 separately. If you are interested, there is now a 'five-integration' branch in Z2 SVN where this work is going on. Brian Lloyd brian(a)zope.com V.P. Engineering 540.361.1716 Zope Corporation http://www.zope.com

Problems with non-zope object attribute access
by Dario Lopez-Kästen 11 Mar '05

11 Mar '05

Hello, I have this serious show-stopper problem that I do not know how to get around, so any input is appreciated. I am building a Product that is basically a Zope interface to a set of non-Zope APIs to a directory system. In my product at one point I receive a list of (not zope-based) objects from a factory method in the API set. These objects all represent Persons with all necesary attributes and lazy DB lookup etc. Very neat. What is not so neat is that I have no means of zope-unpack them and display them in a ZPT. I have tried the following in my product class: def _zopify(self, o): # wrap object o in a an Acquisition.ImplicitAcquisitionWrapper # add __allow_access_to_unprotected_subobjects = 1 # Return o o.__allow_access_to_unprotected_subobjects = 1 return Acquisition.ImplicitAcquisitionWrapper(o, self) and in my product code I do this. plist = get_non_zope_person_object_list(...) return [self._zopify(person) for person in plist ] but I still get """ The container has no security assertions. Access to 'lname' of (Products.pdbapi.person.Person instance at 0x03449DA0) denied. """ errors when I try to access the attributes of a person object in the list. I am very reluctant to add zope-specific stuff to the set of APIs because they are used in several other places that are not Zope-specific. I also would like not to have to duplicate code existing in the API just to have it become Zope-friendly, so I am trying to find alternative paths here. Any help is appreciated.

February Bug Day Roundup
by Chris Withers 07 Mar '05

07 Mar '05

Hi All, Ug, looks like things went from bad to worse. January's bug day was very quiet, February's was totally dead. Not a single issue was dealt with on the bug day and #zope-dev was dead for the whole day. I'm going to take a break from running bugdays for a few months since I guess we're suffering from bug-day-overload... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
