## Method Details

actionAction() public method

Runs an action defined in the generator.

Given an action named "xyz", the method "actionXyz()" in the generator will be called. If the method does not exist, a 400 HTTP exception will be thrown.

public mixed actionAction ( $id, $name )
$id | string | The ID of the generator
$name | string | The action name
return | mixed | The result of the action.
throws | yii\web\NotFoundHttpException | if the action method does not exist.

actionDiff() public method

public void actionDiff ( $id, $file )
$id |  |
$file |  |

actionIndex() public method

public void actionIndex ( )

actionPreview() public method

public void actionPreview ( $id, $file )
$id |  |
$file |  |

actionView() public method

public void actionView ( $id )
$id |  |

beforeAction() public method

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.

loadGenerator() protected method

Loads the generator with the specified ID.

protected yii\gii\Generator loadGenerator ( $id )
$id | string | The ID of the generator to be loaded.
return | yii\gii\Generator | The loaded generator
throws | yii\web\NotFoundHttpException |
