MongoDbManager represents an authorization manager that stores authorization information in MongoDB.

Manager uses 3 collections for the RBAC data storage:

These collection are better to be pre-created with search fields indexed.

Property Details

Hide inherited properties

$assignmentCollection public property

The name of the collection storing authorization item assignments. Defaults to "auth_assignment".

public string|array $assignmentCollection = 'auth_assignment'
$cache public property

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 \yii\caching\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 invalidateCache() to ensure data consistency.

public \yii\caching\Cache|array|string $cache = null
$cacheKey public property

The key used to store RBAC data in cache

See also $cache.

public string $cacheKey = 'rbac'
$db public property

The MongoDB connection object or the application component ID of the MongoDB connection. After the MongoDbManager object is created, if you want to change this property, you should only assign it with a MongoDB connection object.

public yii\mongodb\Connection|array|string $db = 'mongodb'
$itemCollection public property

The name of the collection storing authorization items. Defaults to "auth_item".

public string|array $itemCollection = 'auth_item'
$items protected property

All auth items (name => Item)

protected \yii\rbac\Item[] $items = null
$ruleCollection public property

The name of the collection storing rules. Defaults to "auth_rule".

public string|array $ruleCollection = 'auth_rule'
$rules protected property

All auth rules (name => Rule)

protected \yii\rbac\Rule[] $rules = null
