[Zope] Add ZPT at initialization Zope product

[Casey Duncan]

I'm assuming you are calling=20

parent =3D getattr(self, 'aq_parent', None)

from the __init__ constructor method in the class. One thing to realize i=
s=20
that inside __init__, the object has not been mounted in the ZODB yet and=
=20
therefore has no aq_parent, hence the None result.

Another possibility is that you class does not sublass Acquisition.Implic=
it,=20
which it needs to for aq_parent to work.=20

To get around the former issue check out this ZopeLabs recipe:
