Configuring

First you need to configure model as follows:

class Category extends ActiveRecord
{
    public $leaf;

	public function behaviors() {
		return [
			[
				'class' => ClosureTable::className(),
				'tableName' => 'category_tree'
			],
		];
	}

	public static function find()
	{
		return new CategoryQuery(static::className());
	}
}

Second you need to configure query model as follows:

class CategoryQuery extends ActiveQuery
{
	public function behaviors() {
		return [
			[
				'class' => ClosureTableQuery::className(),
				'tableName' => 'category_tree'
			],
		];
	}
}

Migrations / Changing database schema

After configuring your model, you must copy migration file from behavior migrations folder to your project migrations folder. Please read the comments in file, change migration as you need and run migration:

php yii migrate

Also you change database schema directly using an example from .sql dump file in schema folder.
