Ok hopefully this will be the last time we need to explain this...
App::import() only includes the file. So you would new to create a new
instance every time. This is not recommended
ClassRegistry::init() loads the file, adds the instance to the a
object map and returns the instance. This is an easy and convenient
way to access models.
Controller::loadModel(); Uses ClassRegistry::init() adds the model to
a property of the controller and also allows persistModel to be
enabled.
While you "can" do any of these things, you should ask yourself why
you are creating dependencies on models that are not natural to the
controller. If you "have" to do use any of these, then I would do so
in reverse order of the way i described them. IE, Controller::loadModel
() then CR::init() and actually I never use App::import() for models.
Hope this helps.
