/**
|
|
* Application controller class for organization of business logic.
|
|
* Provides basic functionality, such as rendering views inside layouts,
|
|
* automatic model availability, redirection, callbacks, and more.
|
|
*
|
|
* Controllers should provide a number of 'action' methods. These are public methods on the controller
|
|
* that are not prefixed with a '_' and not part of Controller. Each action serves as an endpoint for
|
|
* performing a specific action on a resource or collection of resources. For example adding or editing a new
|
|
* object, or listing a set of objects.
|
|
*
|
|
* You can access request parameters, using `$this->request`. The request object contains all the POST, GET and FILES
|
|
* that were part of the request.
|
|
*
|
|
* After performing the required actions, controllers are responsible for creating a response. This usually
|
|
* takes the form of a generated View, or possibly a redirection to another controller action. In either case
|
|
* `$this->response` allows you to manipulate all aspects of the response.
|
|
*
|
|
* Controllers are created by Dispatcher based on request parameters and routing. By default controllers and actions
|
|
* use conventional names. For example `/posts/index` maps to `PostsController::index()`. You can re-map urls
|
|
* using Router::connect().
