In my opinion:
- 1 set() or 2 set() doesn't matter.
- Doing a manual foreach to create an array for devices list seems to be going
against the framework, if there builtin 1 liner for it ..
- also the check your sql_dump debug output of queries, on my example there
should be 2 very simple sql like "select * from user id = X" and "select * rom
devices where user_id = X"
if you don't use containable you could be fetching unnecessary data from
changes table for example.
controller:
$this->set('devices',$this->Customer->Device->find('list',array('conditions' =>
array('customer_id'=>$customerId))));
view:
<?php echo $this->Form->input('device_id', array('empty' => '-----')); ?>
