Override default sort for ActiveDataProvider in Yii2

Question

I have a lot of models using created_time. And I want all of the GridViews to show the models sorted by created_time DESC.

Right now I write something like this

$dataProvider = new \yii\data\ActiveDataProvider([
        'query' => MyModel::find(),
        'sort' => [
            'defaultOrder' => [
                'created_time' => SORT_DESC
            ]
        ],
    ]);

Instead of writing all of sort configuration I tried ways below but nothing works.

1. Using container

   \Yii::$container->set(\yii\data\ActiveDataProvider::class,
           [
       'sort' => [
           'defaultOrder' => [
               'created_time' => SORT_DESC
           ]
       ]
   ]);
   

2. Overriding the sort in extended class.

   class ActiveDataProvider extends \yii\data\ActiveDataProvider {
   
       public $sort = [
           'defaultOrder' => [
               'created_time' => SORT_DESC
           ]
       ];
   
    }
   

3. Overriding before init() in the extended class works, but it won't work if the instantiation tries to override again.

   class ActiveDataProvider extends \yii\data\ActiveDataProvider {
       public function init() {
           $this->sort = [
               'defaultOrder' => [
                   'created_time' => SORT_DESC
               ]
           ];
           parent::init();
       }
   
   }
   
   //but this won't work if I want to use the ascending
   $dataProvider = new \app\components\data\ActiveDataProvider([
       'query' => MyModel::find(),
       'sort' => [
           'defaultOrder' => [
               'created_time' => SORT_ASC
           ]
       ],
   ]);
   

Answer 1

To do this for a single GridView, you can add 'defaultOrder' => ['created_time' => SORT_DESC] to the array that is accepted by setSort():

    $dataProvider->setSort([
        'attributes' => [
            'id',
            ...
        ],
        'defaultOrder' => ['created_time' => SORT_DESC]
    ]);

Answer 2

You should do this for yii\data\Sort and not for yii\data\ActiveDataProvider. See the documentation to $sort property.

1) With container:

use Yii;

...

Yii::$container->set(\yii\data\Sort::className(),
    'defaultOrder' => [
        'created_time' => SORT_DESC,
    ],
]);

2) Overriding class:

class Sort extends yii\data\Sort
{
    public $defaultOrder' = [
        'created_time' => SORT_DESC,
    ];
}
