optional null Object::__construct()
__get( string $name )
Provides backwards compatibility access to the request object properties. Also provides the params alias.

$method
boolean
afterScaffoldSaveError( string $method )
This method should be overridden in child classes.
$method
boolean
beforeFilter( )

beforeRedirect( string|array $url , integer $status null , boolean $exit true )
The beforeRedirect method is invoked when the controller's redirect method is called but before any further action.
If this method returns false the controller will not continue on to redirect the request. The $url, $status and $exit variables have same meaning as for the controller's method. You can also return a string which will be interpreted as the URL to redirect to or return associative array with key 'url' and optionally 'status' and 'exit'.
$url

This provides some of the DRY magic CakePHP provides. If you want to shut it off, redefine this method as an empty function.
$properties
$class
$normalize

Allows setting of multiple properties of the object in a single line of code. Will only set properties that are part of a class declaration.

requestAction( string|array $url , array $extra array() )
Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.
Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()
POST and GET data can be simulated in requestAction. Use $extra['url']
for GET data. The $extra['data']
parameter allows POST data simulation.

public boolean
Set to true to automatically render the view after action logic.
true
public mixed
Used to define methods a controller that will be cached. To cache a single action, the value is set to an array containing keys that match action names and values that denote cache expiration times (in seconds).
Example:
public $cacheAction = array( 'view/23/' => 21600, 'recalled/' => 86400 );
$cacheAction can also be set to a strtotime() compatible string. This marks all the actions in the controller for view caching.
