How to pass url to Yii2 controller?

Question

Yii

Let's say they access the site page. The domain.com/products/samsung-548z
request is passed to the show method in the products controller, obviously the model should get inside the method. samsung-548z but how to transfer it there?

public function actionShow($model)
    {
         var_dump($model);
    }

Says Bad Request (#400) Missing required parameters: model
Where and how can I pick it up?

Answer 1

In general, $model = Yii::$app->request->get();what you did depends on what is written in your rules

Answer 2

You need to write a rule in the urlManager in the main.php config (or web.php for basic)
'products/<model:[\w\-]+>' => 'products/show',

Answer 3

Write the corresponding rule, an example can be viewed here
