Note that the only time you really have to care about what your base classes did is if you need to redefine the permission used cover an inherited attribute. For ex: class Posting: # doAction_A is under view permission __ac_permissions__ = ( ('View', ('doAction_A',), ('Anonymous', 'Manager')), ) def doAction_A(self): ... class Article(Posting): # For Articles, I want doAction_A to be under the 'Spam' # permission. __ac_permissions__ = ( ('View', ('doAction_B',), ('Anonymous', 'Manager')), ('Spam', ('doAction_A',), ('Anonymous', 'Manager')), ) Hope this helps!
