How to conditionally display elements in a standard CRUD module in YII2?

Question

Yii

I created a table, filled it with data, made a model, then made CRUD through Gii, displays all the data.
The question is, is it possible to make a Where condition to display only those fields and how to do it, where user_id = Yii::$app->user->identity->getId()

Answer 1

Good afternoon.
Create a method in the controller

public function findModel()
  {
    if(!$model = Users::findOne(Yii::$app->user->identity->getId())){
      return false;
    }

    return $model;
  }

You can display the required fields using this method.

public function actionIndex()
  {
    return $this->render('index', ['model' => $this->findModel()]);
  }
