yii2 wählen Spalte aus Beziehungstabelle Probleme

Question

i alle devlopers Tabellendaten wählen möchten, mit nur „username“ Spalte in Benutzertabelle

ich dies schreibe, aber ich bekomme Fehler

$model = Developers::find()->select('*')->with(['users' => function($q){ 
      $q->select('username'); 
     }])->asArray()->all(); 

meine Entwickler „developer_id“ Spalte Beziehung mit id-Spalte Benutzertabelle so in Developers Modell schrieb i

public function getUsers() 
    { 
     return $this->hasOne(User::className(), ['id' => 'developer_id']); 
    } 

Fehler ist

Versuchen Sie folgendes:

Developers::find()->select('developers.*, user.username')->joinWith(['users'])->asArray()->all()
