Yii2 generic behaviour in all models

Question

How Can I add a generic behaviour function that would work for all models. I have added this code in all models. Now I don't want to repeat the same function in all models.

Answer 1

You can create a CustomModel class that extends ActiveRecord. In CustomModel, add the method that you want:

class CustomModel extends \yii\db\ActiveRecord {
     public function custom_function() {
         //Function details
     }
}

Then make your models extend CustomModel

class Book extends CustomModel {

}

That way you can use this method in all your models that extends CustomModel without having to implement this method in each of them.
