How to format 'YEAR' column in yii2 migration?

Question

Yii

I create a migration, the column in the database should be of type year(4) and look like this: '2016'.
If you do it like this:

public function up()
    {
        $this->createTable('films', [
...
            'year' => $this->dateTime(),
...
        ]);
    }

then it turns out like this: '0000-00-00 00:00:00'
Tell me, how is it right?

Answer 1

'year' => 'year'
