Yii2 - how to store null values?

Question

Yii

Good afternoon, I'm interested in the problem that exists in the first version of the framework. I would like to store NULL values ​​in valid columns of database tables, but after mass assignment of model attributes, empty lines get there. How to deal with it and is it worth it at all? Are you using a validator a la empty2null?

Answer 1

Use the default validator.
