I completed implementation of zcml-based import and export step
registration on the wichert-zcml-steps branch. The syntax for import

Dear all,
a simple question with hopefully a simple answer! How do I access
objects from an object's context or hierarchy? Specifically I'd like
to be able to access a ZopeDA connection for a site. Is it correct
that I have to register this somewhere to be able to access it from a
portal

da = getattr('my_da_or_what_ever', context, None)
Doesn't that only work within a PythonScript? I need access from
within a content type, ie. real Python code?

That will work within your content class code as well.

It's called acquisition and it works everywhere. Try it.
Yes,

Note that getattr('foo', context, None) is wrong.
Wichert has the correct syntax; I didn't even pay attention to the
syntax originally. :)

If it's in a content type's class, why not:
id = getattr(self, 'da_id', None)
Just using self as the context should be fine.

you call that within your method.
mm, currently

__init__ is indeed the wrong place: when the instance is created it is
not placed in an acquisition context yet.
That would indeed explain things!!! Is it okay to call a method which
does this from __init__ ?
def __init__(self, id):

there are two places where you can put your code, in both cases
acquisition is fully functional.
Thanks very much! Now hit an error that my database connection object
can't be pickled but at least I can access it! :-D
