Permission Control

Object-level access control by Permission. Permission codes are arbitrary strings which can be selected on a group-by-group basis.

class Article extends DataObject implements PermissionProvider {
        static $api_access = true;

        public function canView($member = false) {
                return Permission::check('ARTICLE_VIEW');
        }
        public function canEdit($member = false) {
                return Permission::check('ARTICLE_EDIT');
        }
        public function canDelete() {
                return Permission::check('ARTICLE_DELETE');
        }
        public function canCreate() {
                return Permission::check('ARTICLE_CREATE');
        }
        public function providePermissions() {
                return array(
                        'ARTICLE_VIEW' => 'Read an article object',
                        'ARTICLE_EDIT' => 'Edit an article object',
                        'ARTICLE_DELETE' => 'Delete an article object',
                        'ARTICLE_CREATE' => 'Create an article object',
                );
        }
}

Object-level access control by Group membership:

class Article extends DataObject {
        static $api_access = true;

        public function canView($member = false) {
                if(!$member) $member = Member::currentUser();
        return $member->inGroup('Subscribers');
        }
        public function canEdit($member = false) {
                if(!$member) $member = Member::currentUser();
        return $member->inGroup('Editors');
        }

        // ...
}
