YII2 Restful post和TimestampBehavior

Question

I'm trying to use TimestampBehavior in my Restful API created Yii2, but when I create a new entity using the POST endpoint, the return data is quite strange.

{
  "i18_id": 3,
  "language": "es",
  "text": "un test de traducción",
  "created_at": {
    "expression": "NOW()",
    "params": [ ]
  },
  "updated_at": {
    "expression": "NOW()",
    "params": [ ]
  },
  "id": 2
}

When I GET the entity later everything looks fine.

Here is how I've declared the Behavior in my model:

public function behaviors()
{
    return [
        'timestamp' => [
            'class' => 'yii\behaviors\TimestampBehavior',
            'attributes' => [
                ActiveRecord::EVENT_BEFORE_INSERT => ['created_at', 'updated_at'],
                ActiveRecord::EVENT_BEFORE_UPDATE => ['updated_at'],
            ],
            'value' => new Expression('NOW()'),
        ],
    ];
}

I guess you have added the Entry in your test and return the model just added.

I guess a simple $model->refresh(); will fill the values.

See official docs here.
