ActiveController implements a common set of actions for supporting RESTful access to ActiveRecord.

The class of the ActiveRecord should be specified via $modelClass, which must implement yii\db\ActiveRecordInterface. By default, the following actions are supported:

  • index: list of models
  • view: return the details of a model
  • create: create a new model
  • update: update an existing model
  • delete: delete an existing model
  • options: return the allowed HTTP methods

You may disable some of these actions by overriding actions() and unsetting the corresponding actions.

To add a new action, either override actions() by appending a new action class or write a new action method. Make sure you also override verbs() to properly declare what HTTP methods are allowed by the new action.

You should usually override checkAccess() to check whether the current user has the privilege to perform the specified action against the specified model.

For more details and usage information on ActiveController, see the guide article on rest controllers.

Property Details

$createScenario public property

The scenario used for creating a model.

See also yii\base\Model::scenarios().

public string $createScenario = \yii\base\Model::SCENARIO_DEFAULT
$modelClass public property

The model class name. This property must be set.

Method Details

actions() public method

Declares external actions for the controller.

This method is meant to be overwritten to declare external actions for the controller. It should return an array, with array keys being action IDs, and array values the corresponding action class names or action configuration arrays. For example,

return [
    'action1' => 'app\components\Action1',
    'action2' => [
        'class' => 'app\components\Action2',
        'property1' => 'value1',
        'property2' => 'value2',
    ],
];

Yii::createObject() will be used later to create the requested action using the configuration provided here.

public void actions ( )
checkAccess() public method

Checks the privilege of the current user.

This method should be overridden to check whether the current user has the privilege to run the specified action against the specified data model. If the user does not have access, a yii\web\ForbiddenHttpException should be thrown.

public void checkAccess ( $action, $model null, $params = [] )
$action string

The ID of the action to be executed

$model object

The model to be accessed. If null, it means no specific model is being accessed.

$params array

Additional parameters

throws yii\web\ForbiddenHttpException

if the user does not have access

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 ( )
verbs() protected method

Declares the allowed HTTP verbs.

Please refer to \yii\rest\VerbFilter::actions on how to declare the allowed verbs.

protected array verbs ( )
return array

The allowed HTTP verbs.
