Use Model::exists

To ensure that the record does exist, use Model::Exists. For example:

function updateFoo($id, $value) {
    if (!$this->exists($id) {
        return false;
    }

    $this->id = $id;
    return $this->saveField('foo', $value);
}

This would act like so:

$false = $model->updateFoo(false, $value);
$false = $model->updateFoo(0, $value);
$false = $model->updateFoo('doesnotexist', $value);
$true = $model->updateFoo('doesexist', $value);

If you want to just update a field, use the saveField method of the model

$this->Order->id    = $id;
$this->Order->saveField('status', 'VOID');

//Create: id isn't set or is null
$this->Recipe->create();
$this->Recipe->save($this->data);

//Update: id is set to a numerical value 


$this->Recipe->id = 2;
$this->Recipe->save($this->data);

see http://book.cakephp.org/2.0/en/models/saving-your-data.html
