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:
php
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 beforeAction ( |

| $action | the action to be executed. | |
| return | boolean | whether the action should continue to run. |
function beforeAction($event)
{
$this->model_name = ucfirst($_GET['model']);
$this->model_class_name = "app\\models\\" . $this->model_name;
Yii::$app->response->format = 'json';
return parent::beforeAction($event);
}

return true;
