AlumnesGrupsTable.php

$this->belongsTo('Alumnes', [
        'foreignKey' => 'alumne_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsTo('Grups', [
        'foreignKey' => 'grup_id',
        'joinType' => 'INNER'
    ]);

Warum ist das in AvadiariesController.php:

 public function add()
    {
    $avadiary = $this->Avadiaries->newEntity();
        if ($this->request->is('post')) {
            $avadiary = $this->Avadiaries->patchEntity($avadiary, $this->request->data);
            $avadiary->user_id = $this->Auth->user('id');
            if ($this->Avadiaries->save($avadiary)) {
                $this->Flash->success(__('The avadiary has been saved.'));

                return $this->redirect(['action' => 'index']);
            } else {
                $this->Flash->error(__('The avadiary could not be saved. Please, try again.'));
            }
        }
    $alumnesGrups = $this->Avadiaries->AlumnesGrups->find('all', [
    'fields' => ['Alumnes.name'], 
    'contain' =>['Alumnes', 'Grups'], 
    'conditions' => ['Grups.id =' => 1], 
    'order' => ['Alumnes.name' => 'ASC']
    ]);
$this->set(compact('avadiary', 'alumnesGrups'));
        $this->set('_serialize', ['avadiary']);
    }

korrekte Daten zurückgeben, aber wie folgt formatiert:

{"Alumnes": {"name": "Angela Smith"}}?

Wie kann ich nur Angela Smith bekommen? Wenn ich find (all) in find (list) ändere, enthält das Auswahlfeld mehrere leere Optionen.

Vielen Dank
