This is a great little function to drop into your app_controller. I
use it all the time, makes life just a little bit easier. Thought I'd
share it with you all.
/**
* @param string $model Proper name of model
* @param int $id optional primary id of model
* @return array $data from Model::read()
*/
function readOr404($model, $id=null) {
if($id)
$this->{$model}->id = $id;
if($data = $this->{$model}->read()) {
return $data;
} else {
$this->cakeError('error404',
array($this->params['url']));
die;
}
}
