Class yii\base\Module

Constructor.

This method is invoked right after an action within this module is executed.

The method will trigger the EVENT_AFTER_ACTION event. The return value of the method will be used as the action return value.

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

public function afterAction($action, $result)
{
    $result = parent::afterAction($action, $result);
    // your custom code here
    return $result;
}

This method is invoked right before an action within this module 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($action)
{
    if (!parent::beforeAction($action)) {
        return false;
    }

    // your custom code here

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

Creates a controller instance based on the given route.

The route should be relative to this module. The method implements the following algorithm to resolve the given route:

1. If the route is empty, use $defaultRoute;
2. If the first segment of the route is a valid module ID as declared in $modules, call the module's createController() with the rest part of the route;
3. If the first segment of the route is found in $controllerMap, create a controller based on the corresponding configuration found in $controllerMap;
4. The given route is in the format of abc/def/xyz. Try either abc\DefController or abc\def\XyzController class within the controller namespace.

If any of the above steps resolves into a controller, it is returned together with the rest part of the route which will be treated as the action ID. Otherwise, false will be returned.

Creates a controller based on the given controller ID.

The controller ID is relative to this module. The controller class should be namespaced under $controllerNamespace.

Note that this method does not check $modules or $controllerMap.

Returns default module version.

Child class may override this method to provide more specific version detection.

Returns the component instance with the specified ID.

Since version 2.0.13, if a component isn't defined in the module, it will be looked up in the parent module. The parent module may be the application.

Returns the root directory of the module.

It defaults to the directory containing the module class file.

Returns the directory that contains the controller classes according to $controllerNamespace.

Note that in order for this method to return a value, you must define an alias for the root namespace of $controllerNamespace.

Returns the currently requested instance of this module class.

If the module class is not currently requested, null will be returned. This method is provided so that you access the module instance from anywhere within the module.

Returns the directory that contains layout view files for this module.

Retrieves the child module of the specified ID.

This method supports retrieving both child modules and grand child modules.

See also hasModule().

Returns the sub-modules in this module.

Returns an ID that uniquely identifies this module among all modules within the current application.

Note that if the module is an application, an empty string will be returned.

Returns current module version.

If version is not explicitly set, defaultVersion() method will be used to determine its value.

Returns the directory that contains the view files for this module.

Returns a value indicating whether the locator has the specified component definition or has instantiated the component.

Since version 2.0.13, if a component isn't defined in the module, it will be looked up in the parent module. The parent module may be the application.

This method may return different results depending on the value of $checkInstance.

• If $checkInstance is false (default), the method will return a value indicating whether the locator has the specified component definition.
• If $checkInstance is true, the method will return a value indicating whether the locator has instantiated the specified component.

Checks whether the child module of the specified ID exists.

This method supports checking the existence of both child and grand child modules.

Initializes the module.

This method is called after the module is created and initialized with property values given in configuration. The default implementation will initialize $controllerNamespace if it is not set.

If you override this method, please make sure you call the parent implementation.

Runs a controller action specified by a route.

This method parses the specified route and creates the corresponding child module(s), controller and action instances. It then calls yii\base\Controller::runAction() to run the action with the given parameters. If the route is empty, the method will use $defaultRoute.

Defines path aliases.

This method calls Yii::setAlias() to register the path aliases. This method is provided so that you can define path aliases when configuring a module.

Sets the root directory of the module.

This method can only be invoked at the beginning of the constructor.

Sets the currently requested instance of this module class.

Sets the directory that contains the layout files.

Adds a sub-module to this module.

Registers sub-modules in the current module.

Each sub-module should be specified as a name-value pair, where name refers to the ID of the module and value the module or a configuration array that can be used to create the module. In the latter case, Yii::createObject() will be used to create the module.

If a new sub-module has the same ID as an existing one, the existing one will be overwritten silently.

The following is an example for registering two sub-modules:

[
    'comment' => [
        'class' => 'app\modules\comment\CommentModule',
        'db' => 'db',
    ],
    'booking' => ['class' => 'app\modules\booking\BookingModule'],
]

Sets current module version.

Sets the directory that contains the view files.
