# Class yii\rest\ActiveController

Inheritance | yii\rest\ActiveController » yii\rest\Controller » yii\web\Controller » yii\base\Controller » yii\base\Component » yii\base\BaseObject
Implements | yii\base\Configurable, yii\base\ViewContextInterface
Available since version | 2.0
Source Code | https://github.com/yiisoft/yii2/blob/master/framework/rest/ActiveController.php

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.

__call() public method

Defined in: yii\base\Component::__call()

Calls the named method which is not a class method.

This method will check if any attached behavior has the named method and will execute it if available.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name | string | The method name
$params | array | Method parameters
return | mixed | The method return value
throws | yii\base\UnknownMethodException | when calling unknown method

        foreach ($this->_behaviors as $object) {
            if ($object->hasMethod($name)) {
                return call_user_func_array([$object, $name], $params);

This method is called after the object is created by cloning an existing one.

It removes all behaviors because they are attached to the old object.

public void __clone ( )

Source code

                    public function __clone()
    {
        $this->_events = [];
        $this->_eventWildcards = [];

        parent::__construct($config);
    }

__get() public method

Defined in: yii\base\Component::__get()

Returns the value of a component property.

This method will check in the following order and act accordingly:

- a property defined by a getter: return the getter result
- a property of a behavior: return the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `$value = $component->property;`.

See also __set().

public mixed __get ( $name )
$name | string | The property name
return | mixed | The property value or the value of a behavior's property
throws | yii\base\UnknownPropertyException | if the property is not defined
throws | yii\base\InvalidCallException | if the property is write-only.

Source code

                    public function __get($name)
    {
        $getter = 'get' . $name;
        if (method_exists($this, $getter)) {
            // read property, e.g. getName()
            return $this->$getter();
        }
        // behavior property

            throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
        }
        throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
    }

__isset() public method

Defined in: yii\base\Component::__isset()

Checks if a property is set, i.e. defined and not null.

This method will check in the following order and act accordingly:

- a property defined by a setter: return whether the property is set
- a property of a behavior: return whether the property is set
- return `false` for non existing properties

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `isset($component->property)`.

                return $behavior->$name !== null;
            }
        }
        return false;
    }

__set() public method

Defined in: yii\base\Component::__set()

Sets the value of a component property.

This method will check in the following order and act accordingly:

- a property defined by a setter: set the property value
- an event in the format of "on xyz": attach the handler to the event "xyz"
- a behavior in the format of "as xyz": attach the behavior named as "xyz"
- a property of a behavior: set the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `$component->property = $value;`.

See also __get().

public void __set ( $name, $value )
$name | string | The property name or the event name
$value | mixed | The property value
throws | yii\base\UnknownPropertyException | if the property is not defined
throws | yii\base\InvalidCallException | if the property is read-only.

            return;
        } elseif (strncmp($name, 'on ', 3) === 0) {
            // on event: attach event handler
            $this->on(trim(substr($name, 3)), $value);
            return;
        } elseif (strncmp($name, 'as ', 3) === 0) {
            // as behavior: attach behavior
            $name = trim(substr($name, 3));
            $this->attachBehavior($name, $value instanceof Behavior ? $value : Yii::createObject($value));

        throw new InvalidCallException('Unsetting an unknown or read-only property: ' . get_class($this) . '::' . $name);
    }

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.

    }

attachBehavior() public method

Defined in: yii\base\Component::attachBehavior()

Attaches a behavior to this component.

This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the yii\base\Behavior::attach() method.

See also detachBehavior().

public yii\base\Behavior attachBehavior ( $name, $behavior )
$name | string | The name of the behavior.

$behavior

string|array|yii\base\Behavior

The behavior configuration. This can be one of the following:

- a yii\base\Behavior object
- a string specifying the behavior class
- an object configuration array that will be passed to Yii::createObject() to create the behavior object.

return | yii\base\Behavior | The behavior object

Source code

                    public function attachBehavior($name, $behavior)
    {
        $this->ensureBehaviors();
        return $this->attachBehaviorInternal($name, $behavior);
    }

attachBehaviors() public method

Defined in: yii\base\Component::attachBehaviors()

Attaches a list of behaviors to the component.

Each behavior is indexed by its name and should be a yii\base\Behavior object, a string specifying the behavior class, or an configuration array for creating the behavior.

See also attachBehavior().

public void attachBehaviors ( $behaviors )
$behaviors | array | List of behaviors to be attached to the component

Source code

                    public function attachBehaviors($behaviors)
    {

            $this->attachBehaviorInternal($name, $behavior);
        }
    }

beforeAction() public method

Defined in: yii\web\Controller::beforeAction()

This method is invoked right before an action is executed.

The method will trigger the EVENT_BEFORE_ACTION event. The return value of the method will determine whether the action should continue to run.

In case the action should not run, the request should be handled inside of the `beforeAction` code by either providing the necessary output or redirecting the request. Otherwise the response will be empty.

If you override this method, your code should look like the following:

    public function beforeAction($action)
    {
        // your custom code here, if you want the code to run before action filters,
        // which are triggered on the [[EVENT_BEFORE_ACTION]] event, e.g. PageCache or AccessControl

        if (!parent::beforeAction($action)) {
            return false;
        }

        // other custom code here

        return true; // or false to not run the action
    }

public boolean beforeAction ( $action )
$action | yii\base\Action | The action to be executed.
return | boolean | Whether the action should continue to run.

Source code

                    public function beforeAction($action)

                throw new BadRequestHttpException(Yii::t('yii', 'Unable to verify your data submission.'));
            }
            return true;
        }
        return false;
    }

Defined in: yii\rest\Controller::behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

    'behaviorName' => [
        'class' => 'BehaviorClass',
        'property1' => 'value1',
        'property2' => 'value2',
    ]

Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

public array behaviors ( )
return | array | The behavior configurations.

bindActionParams() public method

Defined in: yii\web\Controller::bindActionParams()

Binds the parameters to the action.

This method is invoked by yii\base\Action when it begins to run with the given parameters. This method will check the parameter names that the action requires and return the provided parameters according to the requirement. If there is any missing parameter, an exception will be thrown.

public array bindActionParams ( $action, $params )
$action | yii\base\Action | The action to be bound with parameters
$params | array | The parameters to be bound to the action
return | array | The valid parameters that the action can run with.
throws | yii\web\BadRequestHttpException | if there are missing or invalid parameters.

Returns a value indicating whether a property can be read.

A property can be read if:

- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when `$checkVars` is true);
- an attached behavior has a readable property of the given name (when `$checkBehaviors` is true).

See also canSetProperty().

public boolean canGetProperty ( $name, $checkVars = true, $checkBehaviors = true )
$name | string | The property name
$checkVars | boolean | Whether to treat member variables as properties

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

createAction() public method

Defined in: yii\base\Controller::createAction()

Creates an action based on the given action ID.

The method first checks if the action ID has been declared in actions(). If so, it will use the configuration declared there to create the action object. If not, it will look for a controller method whose name is in the format of `actionXyz` where `xyz` is the action ID. If found, an yii\base\InlineAction representing that method will be created and returned.

public yii\base\Action|null createAction ( $id )
$id | string | The action ID.
return | yii\base\Action|null | The newly created action instance. Null if the ID doesn't resolve into any action.

public yii\base\View|yii\web\View getView ( )
return | yii\base\View|yii\web\View | The view object that can be used to render views or view files.

Source code

                    public function getView()

        if ($this->_view === null) {
            $this->_view = Yii::$app->getView();
        }
        return $this->_view;
    }

            $this->_viewPath = $this->module->getViewPath() . DIRECTORY_SEPARATOR . $this->id;
        }
        return $this->_viewPath;
    }

goBack() public method

Defined in: yii\web\Controller::goBack()

Redirects the browser to the last visited page.

You can use this method in an action by returning the yii\web\Response directly:

    return $this->goBack();

For this function to work you have to set the return URL in appropriate places before.

See also yii\web\User::getReturnUrl().

public yii\web\Response goBack ( $defaultUrl = null )
$defaultUrl | string|array|null | The default return URL in case it was not set previously. If this is null and the return URL was not set previously, yii\web\Application::$homeUrl will be redirected to. Please refer to yii\web\User::setReturnUrl() on accepted format of the URL.
return | yii\web\Response | The current response object

Source code

                    public function goBack($defaultUrl = null)

        }
    }

off() public method

Defined in: yii\base\Component::off()

Detaches an existing event handler from this component.

This method is the opposite of on().

                if (empty($this->_eventWildcards[$name])) {
                    unset($this->_eventWildcards[$name]);
                }
            }
        }
        return $removed;
    }

on() public method

Defined in: yii\base\Component::on()

Attaches an event handler to an event.

The event handler must be a valid PHP callback. The following are some examples:

    function ($event) { ... }         // anonymous function
    [$object, 'handleClick']          // $object->handleClick()
    ['Page', 'handleClick']           // Page::handleClick()
    'handleClick'                     // global function handleClick()

The event handler must be defined with the following signature,

    function ($event)

where `$event` is an yii\base\Event object which includes parameters associated with the event.

Since 2.0.14 you can specify event name as a wildcard pattern:

    $component->on('event.group.*', function ($event) {
        Yii::trace($event->name . ' is triggered.');
    });

See also off().

public void on ( $name, $handler, $data = null, $append = true )
$name | string | The event name
$handler | callable | The event handler
$data | mixed | The data to be passed to the event handler when the event is triggered. When the event handler is invoked, this data can be accessed via yii\base\Event::$data.
$append | boolean | Whether to append new event handler to the end of the existing handler list. If false, the new handler will be inserted at the beginning of the existing handler list.

Source code

                    public function on($name, $handler, $data = null, $append = true)
    {
        $this->ensureBehaviors();
        if (strpos($name, '*') !== false) {
            if ($append || empty($this->_eventWildcards[$name])) {
                $this->_eventWildcards[$name][] = [$handler, $data];
            } else {
                array_unshift($this->_eventWildcards[$name], [$handler, $data]);
            }
            return;
        }
        if ($append || empty($this->_events[$name])) {
            $this->_events[$name][] = [$handler, $data];
        } else {
            array_unshift($this->_events[$name], [$handler, $data]);
        }
    }

redirect() public method

Defined in: yii\web\Controller::redirect()

Redirects the browser to the specified URL.

This method is a shortcut to yii\web\Response::redirect().

You can use it in an action by returning the yii\web\Response directly:

    // stop executing this action and redirect to login page
    return $this->redirect(['login']);

public yii\web\Response redirect ( $url, $statusCode = 302 )

$url

string|array

The URL to be redirected to. This can be in one of the following formats:

- a string representing a URL (e.g. "https://example.com")
- a string representing a URL alias (e.g. "@example.com")
- an array in the format of `[$route, ...name-value pairs...]` (e.g. `['site/index', 'ref' => 1]`) yii\helpers\Url::to() will be used to convert the array into a URL.

Any relative URL that starts with a single forward slash "/" will be converted into an absolute one by prepending it with the host info of the current request.

$statusCode | integer | The HTTP status code. Defaults to 302. See https://tools.ietf.org/html/rfc2616#section-10 for details about HTTP status code
return | yii\web\Response | The current response object

Source code

                    public function redirect($url, $statusCode = 302)
    {
        // calling Url::to() here because Response::redirect() modifies route before calling Url::to()
        return $this->response->redirect(Url::to($url), $statusCode);
    }

refresh() public method

Defined in: yii\web\Controller::refresh()

Refreshes the current page.

This method is a shortcut to yii\web\Response::refresh().

You can use it in an action by returning the yii\web\Response directly:

    // stop executing this action and refresh the current page
    return $this->refresh();

public yii\web\Response refresh ( $anchor = '' )
$anchor | string | The anchor that should be appended to the redirection URL. Defaults to empty. Make sure the anchor starts with '#' if you want to specify it.
return | yii\web\Response | The response object itself

Source code

                    public function refresh($anchor = '')
    {
        return $this->response->redirect($this->request->getUrl() . $anchor);
    }

render() public method

Defined in: yii\base\Controller::render()

Renders a view and applies layout if available.

The view to be rendered can be specified in one of the following formats:

- path alias (e.g. "@app/views/site/index");
- absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the view path of the application.
- absolute path within module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the view path of $module.
- relative path (e.g. "index"): the actual view file will be looked for under $viewPath.

To determine which layout should be applied, the following two steps are conducted:

1. In the first step, it determines the layout name and the context module:

- If $layout is specified as a string, use it as the layout name and $module as the context module;
- If $layout is null, search through all ancestor modules of this controller and find the first module whose layout is not null. The layout and the corresponding module are used as the layout name and the context module, respectively. If such a module is not found or the corresponding layout is not a string, it will return false, meaning no applicable layout.

1. In the second step, it determines the actual layout file according to the previously found layout name and context module. The layout name can be:

- a path alias (e.g. "@app/views/layouts/main");
- an absolute path (e.g. "/main"): the layout name starts with a slash. The actual layout file will be looked for under the layout path of the application;
- a relative path (e.g. "main"): the actual layout file will be looked for under the layout path of the context module.

If the layout name does not contain a file extension, it will use the default one `.php`.

public string render ( $view, $params = [] )
$view | string | The view name.
$params | array | The parameters (name-value pairs) that should be made available in the view. These parameters will not be available in the layout.
return | string | The rendering result.
throws | yii\base\InvalidArgumentException | if the view file or the layout file does not exist.

Source code

                    public function render($view, $params = [])
    {
        $content = $this->getView()->render($view, $params, $this);
        return $this->renderContent($content);
    }

renderAjax() public method

Defined in: yii\web\Controller::renderAjax()

Renders a view in response to an AJAX request.

This method is similar to renderPartial() except that it will inject into the rendering result with JS/CSS scripts and files which are registered with the view. For this reason, you should use this method instead of renderPartial() to render a view to respond to an AJAX request.

public string renderAjax ( $view, $params = [] )
$view | string | The view name. Please refer to render() on how to specify a view name.
$params | array | The parameters (name-value pairs) that should be made available in the view.
return | string | The rendering result.

Source code

                    public function renderAjax($view, $params = [])
    {
        return $this->getView()->renderAjax($view, $params, $this);
    }

renderContent() public method (available since version 2.0.1)

Defined in: yii\base\Controller::renderContent()

Renders a static string by applying a layout.

public string renderContent ( $content )
$content | string | The static string being rendered
return | string | The rendering result of the layout with the given static string as the `$content` variable. If the layout is disabled, the string will be returned back.

Source code

                    public function renderContent($content)
    {
        $layoutFile = $this->findLayoutFile($this->getView());
        if ($layoutFile !== false) {
            return $this->getView()->renderFile($layoutFile, ['content' => $content], $this);
        }
        return $content;
    }

renderFile() public method

Defined in: yii\base\Controller::renderFile()

Renders a view file.

public string renderFile ( $file, $params = [] )
$file | string | The view file to be rendered. This can be either a file path or a path alias.
$params | array | The parameters (name-value pairs) that should be made available in the view.
return | string | The rendering result.
throws | yii\base\InvalidArgumentException | if the view file does not exist.

Source code

                    public function renderFile($file, $params = [])
    {
        return $this->getView()->renderFile($file, $params, $this);
    }

renderPartial() public method

Defined in: yii\base\Controller::renderPartial()

Renders a view without applying layout.

This method differs from render() in that it does not apply any layout.

public string renderPartial ( $view, $params = [] )
$view | string | The view name. Please refer to render() on how to specify a view name.
$params | array | The parameters (name-value pairs) that should be made available in the view.
return | string | The rendering result.
throws | yii\base\InvalidArgumentException | if the view file does not exist.

Source code

                    public function renderPartial($view, $params = [])
    {
        return $this->getView()->render($view, $params, $this);
    }

run() public method

Defined in: yii\base\Controller::run()

Runs a request specified in terms of a route.

The route can be either an ID of an action within this controller or a complete route consisting of module IDs, controller ID and action ID. If the route starts with a slash '/', the parsing of the route will start from the application; otherwise, it will start from the parent module of this controller.

See also runAction().

public mixed run ( $route, $params = [] )
$route | string | The route to be handled, e.g., 'view', 'comment/view', '/admin/comment/view'.
$params | array | The parameters to be passed to the action.
return | mixed | The result of the action.

Source code

                    public function run($route, $params = [])

    }

runAction() public method

Defined in: yii\base\Controller::runAction()

        }
        Yii::debug('Route to run: ' . $action->getUniqueId(), __METHOD__);
        if (Yii::$app->requestedAction === null) {
            Yii::$app->requestedAction = $action;
        }
