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.

属性详情

$createScenario public 属性

The scenario used for creating a model.

参见 yii\base\Model::scenarios().

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

The model class name. This property must be set.

public string $modelClass null
$updateScenario public 属性

The scenario used for updating a model.

参见 yii\base\Model::scenarios().

public string $updateScenario = \yii\base\Model::SCENARIO_DEFAULT

方法详情

actions() public 方法

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 方法

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 方法

初始化对象.

在使用给定的配置初始化对象之后, 在构造函数的末尾调用此方法.

public void init ( )
verbs() protected 方法

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.
