Do you need to create models?

Question

Yii

Now I am writing an API for AngularJS on Yii2. Previously, I always used incoming parameters like this:

Yii::$app->getRequest()->getQueryParam('paramName')

And now I thought, maybe it would be more correct to create a model (with validations) for each method where reception of parameters is needed?

Answer 1

We create at home ... it is necessary to validate this way and that way, whether it is in the model or not.
