[Zope-dev] Problems with non-zope object attribute access

[Dario Lopez-Kästen]

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.
Thanks,
