Hello, is it possible for a single method, under Zope 2.1.6, to have several permissions? ie __ac_permission__ = ( ('edit my data', 'edit_data'), ('edit others\'s data', 'edit_data'), ) I have the scenario where a user can edit *its* data but not other users's data, unless he has a special role. however, the method used to edit one's data is the same. So I make sure inside the edit_data method that the user has the adequate permissions if he tries to edit another one's data. this does not work. indeed, lib/python/AccessControl/Permission.py reads: # Attribute names which appear in a # permission may not appear in any other permission defined # by the object. thanks in advance for any advices. regards, jephte.clain@univ-reunion.fr
