Dynamic Model Binding in CakePHP

One topic in CakePHP that took some time to wrap our heads around was binding to a model dynamically – that is, if you’re working in a Controller and would like to access another Model without registering the Model in the $uses array (exposing the model to the entire Controller). On occasion, this can be a handy snippet – for example in a switch statement where you’re segregating calls to different Models based on a certain criteria.
switch ($type) { case 0: $model = 'FinanceNews'; break; case 1: $model = 'SportsNews'; break; case 2: $model = 'LocalNews'; break; } App::Import('Model', $model); $this->DynamicModel = new $model; $conditions = array( 'conditions'=> array($model.'.published' => 1), 'fields'=> array($model.'.id',$model.'.title',$model.'.news_date'), 'order' => $model.'.news_date DESC', 'limit' => 10 ); $this->DynamicModel->find('all', $conditions);
