[Zope] Ticking Security boxes via Python (still not solved)

[kapil thangavelu]

read the relevant chapter about security from the developer's guide it shows 
how to create default roles for certain methods.

the reason the below isn't working (half-guess, half-experience) is that when 
your object is created it doesn't have access to the acquisition heirarchy

ie 
in manage_add
ob = yourclass(id, title)
 
ob has no context

after you do
self._setObject(id, obj)

you can retrieve the wrapped object via

wrapped_obj = self._getObject(id)
and than call the methods

or you can try this in manage_afterAdd which gets called by the object 
manager after the object is added.
