Integer validator skip validating empty object and trying to insert value to database

[piotr-grzelka]

What steps will reproduce the problem?

class Task extends \yii\db\ActiveRecord
{
    ....
    function rules() {
        return [
            [['name'], 'required'],
            [['deadline'], 'integer']
        ];
    }
    ....
}

class TaskController extends \yii\rest\ActiveController 
{

    function actionCreate() {
        $model = new Task();
        $model->load(Yii::$app->getRequest()->post(), '');
        $model->save();
        return $model;
    }

}

my api request

POST /api/v1/project/tasks HTTP/1.1
Host: icp.pl
Accept: application/json
DNT: 1
Content-Type: application/json;charset=utf-8
Authorization: Bearer ...
Content-Length: 37
Connection: close

{
"deadline":{},
"name":"..."
}

What is the expected result?

HTTP/1.1 422 Data Validation Failed.

[
{
"field": "deadline",
"message": "Deadline must be an integer."
}
]

What do you get instead?

HTTP/1.1 500 Internal Server Error

It's default behavior. Set skipOnEmpty to false to change it.

When I set skipEmpty to false I can't send null values.
