My approach is:
1. create json layout in views/layout/json/default.ctp which contains:
<?php
header("Pragma: no-cache");
header("Cache-Control: no-store, no-cache, max-age=0, must-revalidate");
header('Content-Type: application/json');
echo $content_for_layout;
?>
2. create common view for json, says app/views/common/jsonize.ctp --
my controllers use this oftenly, which contains:
<?php echo $javascript->object($result); ?>
3. I put jsonize in app_controller.php, so other controllers will benefit this:
function jsonize() {
$this->layout = 'json/default';
$this->viewPath = "common";
if ( Configure::read('debug') > 0 ) {
Configure::write('debug', 0);
}
if ( !$this->params['named'] ) {
$this->Session->setFlash('Invalid parameter for JSON', 'error');
$this->redirect(array('action'=>'index'));
}
foreach ($this->params['named'] as $field => $value) {
$like = str_replace('*', '%', $value);
$condition[Inflector::singularize($this->name).".$field LIKE"] = $like;
}
$this->{Inflector::singularize($this->name)}->recursive = -1;
$result = $this->{Inflector::singularize($this->name)}->find('all',
array( 'conditions' => $condition ));
$this->set('result', $result);
}
It just a little modification is you used on $this->Model->save()
