Property Details

$checkAccess public property

A PHP callable that will be called when running an action to determine if the current user has the permission to execute the action. If not set, the access check will not be performed. The signature of the callable should be as follows,

function ($action, $model = null) {
    // $model is the requested model instance.
    // If null, it means no specific model (e.g. IndexAction)
}

public callable $checkAccess = null

$findModel public property

A PHP callable that will be called to return the model corresponding to the specified primary key value. If not set, findModel() will be used instead. The signature of the callable should be:

function ($id, $action) {
    // $id is the primary key value. If composite primary key, the key values
    // will be separated by comma.
    // $action is the action object currently running
}

The callable should return the model found, or throw an exception if not found.

public callable $findModel = null

$modelClass public property

Class name of the model which will be handled by this action. The model class must implement yii\db\ActiveRecordInterface. This property must be set.

public string $modelClass = null

Method Details

findModel() public method

Returns the data model based on the primary key given.

If the data model is not found, a 404 HTTP exception will be raised.

public yii\db\ActiveRecordInterface findModel ( $id )
$id	string	The ID of the model to be loaded. If the model has a composite primary key, the ID must be a string of the primary key values separated by commas. The order of the primary key values should follow that returned by the `primaryKey()` method of the model.
return	yii\db\ActiveRecordInterface	The model found
throws	yii\web\NotFoundHttpException	if the model cannot be found

init() public method

Initializes the object.

This method is invoked at the end of the constructor after the object is initialized with the given configuration.

public void init ( )
