Hi Zopists, I try to create ISNGFolder class which is subclassed from Zope Folder class. During instantiation of this ISNGFolder class I also try to set permissions ['View', 'Access contents information'] for role 'Content' by calling manage_role('Content', ['View', 'Access contents information']) function of this object. But some error occurs and I don't know python API very well for folderish objects. Can somebody help me, please?? I use Zope 2.1.6 on Linux Debian Below you can see part of my python product for folderish object and error output of Zope. Begin of code: manage_addISNGFolderForm=HTMLFile('addFolder', globals()) def manage_addISNGFolder(self, cz_id, title='', key_words=[], header='', footer='', createPublic=0, createUserF=0, REQUEST=None): """Add a new 'ISNG Folder' object with id *id*.""" author = repr(REQUEST.AUTHENTICATED_USER) id = cz_id2id(cz_id) ob=ISNGFolder() ob.id = id ob.cz_id = cz_id ob.title = title ob.creation = DateTime.DateTime(time.time()) ob.author = author ob.modifier = author ob.key_words = key_words ob.header = header ob.footer = footer self._setObject(id, ob) ob.manage_role('Content', ['Access contents information', 'View']) if REQUEST is not None: return MessageDialog( title = 'Add ISNGFolder', message = 'New ISNGFolder %s was added.' % ob.getProperty('cz_id'), action = './addFolder' ) class ISNGFolder(Folder): """ISNGFolder class.
