PHP Class yii\rbac\DbManager

The database connection is specified by [[db]]. And the database schema should be as described in "framework/rbac/*.sql". You may change the names of the three tables used to store the authorization data by setting [[itemTable]], [[itemChildTable]] and [[assignmentTable]]. ファイルを表示 Open project: yiisoft/yii2 Class Usage Examples

Public Properties

Property	Type	Description
$assignmentTable		the name of the table storing authorization item assignments. Defaults to "auth_assignment".
$cache		the cache used to improve RBAC performance. This can be one of the following: - an application component ID (e.g. cache) - a configuration array - a Cache object When this is not set, it means caching is not enabled. Note that by enabling RBAC cache, all auth items, rules and auth item parent-child relationships will be cached and loaded into memory. This will improve the performance of RBAC permission check. However, it does require extra memory and as a result may not be appropriate if your RBAC system contains too many auth items. You should seek other RBAC implementations (e.g. RBAC based on Redis storage) in this case. Also note that if you modify RBAC items, rules or parent-child relationships from outside of this component, you have to manually call DbManager::invalidateCache to ensure data consistency.
$cacheKey		the key used to store RBAC data in cache
$db		the DB connection object or the application component ID of the DB connection. After the DbManager object is created, if you want to change this property, you should only assign it with a DB connection object. Starting from version 2.0.2, this can also be a configuration array for creating the object.
$itemChildTable		the name of the table storing authorization item hierarchy. Defaults to "auth_item_child".
$itemTable		the name of the table storing authorization items. Defaults to "auth_item".
$ruleTable		the name of the table storing rules. Defaults to "auth_rule".

Protected Properties

Property	Type	Description
$items		all auth items (name => Item)
$parents		auth item parent-child relationships (childName => list of parents)
$rules		all auth rules (name => Rule)
