• MyAclComponent extends AclBase

• Implements methods

• • lots of.

Initializing now NO Auth initialized Undefined $loaded[Security] YES NO Session initialized NO NO Security initialized Undefined $loaded[Auth] Existent Existent $loaded[Session] Auth::initialize() Auth::__construct() 18. Components - Others

• $Component->enabled = boolean

• SessionComponent::__construct($base)

• Workaround double initialized

• Import original settings

AliasComponent 19. Hack helpers 20. Helpers

• View::_loadHelpers()

AliasHelper 21. Hacks Models 22. Models

• ClassRegistry::init()

• alias option

• Example

• • ClassRegistry::init(array( class => MockPost, alias => Post, ))

• Initialization timing

• • Before Controller::constructClasses

23. Hacks CakeRoute 24. CakeRoute
