cakephp Update field

Question

How do i force cake to update a field and not insert a new record.

It should fail if the id does not exist in the db

I found to force a insertion i can do 'updated' => false so if i do 'updated' => true will it work

Answer 1

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

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

Answer 2

//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);
