[Zope-dev] Questions about BasicUserFolder.authorize

AccessControl.User.BasicUserFolder defines: def authorize(self, user, accessed, container, name, value, roles): what is 'roles' in this context? I'm working on a new release of SUF. I'd like to provide a scriptable method which can decide what roles a user has at a given location. Ideally this would look something like: roles_def= { '/folder/object': {'chris':['Manager'], 'fred':['Anonymous']} } def getUserDetails(self,name,object): return { 'password':'apassword', 'roles':roles_def[object.absolute_url()][name] } Would 'authorize' be the correct place to plug this in? If not, has anyone got any suggestions? cheers, Chris
