Use ContainableBehavior, which will take care of unbinding your
models, as well as the recursive value.
class Survey extends AppModel
{
public $actsAs = array('Containable');
...
controller:
$data = $this->Survey->find(
'first',
array(
'conditions' => array(...),
'contain' => array(
'Question' => array(
'fields' => array(...),
'ResponseOption' => array(
'fields' => array(...)
)
)
)
)
);
Notice that ResponseOption is inside the array for Question, as it's
associated with that model, not Survey. Use debug($data) to see how
the array is returned.
