Question

I have SubjectGroup, which hasMany Subject.

class SubjectGroup extends AppModel {

    public $hasMany = array(
        'Subject' => array('order' => 'Subject.name')
    );

}

class Subject extends AppModel {

    public $belongsTo = array('SubjectGroup');

}

I want to get all SubjectGroups, and recursively retrieve their Subjects, but only the Subjects that have a status of 2.

$this->SubjectGroup->find('all', array(
    'contain' => 'Subject.status != 2',
    'order' => 'SubjectGroup.name'
));

There are no errors, but it just returns all Subjects, even the ones with status = 2.

Answer 1

Well, I finally discovered two problems. I was trying to add an $actsAs definition to the controller, to bring in the behaviour. I completely forgot it’s not the model. You have to bring in the behaviour in the controller action.

class SubjectGroupsController extends AppController {

    public function index()  {

        $this->SubjectGroup->Behaviors->attach('Containable');

        $subjectGroups = $this->SubjectGroup->find('all', array(
            'contain' => 'Subject.status != 2',
            'order' => 'SubjectGroup.name'
        ));
    }

}

But anyway, the condition only seems to work if I use the very basic syntax of:

'contain' => 'Subject.status != 2'

Anything more complex doesn’t seem to work for me:

// DOES NOT WORK
'contain' => array(
    'Subject' => array(
        'conditions' => array('NOT' => array('Subject.status' => 2)),
    ),
)
