Why is there an incorrect loading of data from the associated table into the select?

Question

Yii

Good morning.
There is a form in which there is a select. Data from another table is loaded into this select. The table consists of id and name.

<?php echo $form->field($model, 'id_type')->dropdownList(Type::find()->
select(['name'])->indexBy('name')->column(), ['prompt'=>'Выберите услугу']);?>

for some reason, after submitting the form, 0 comes to id_type, although there are no records with id equal to 0 in the type table.
And if you do that, the correct id comes, but the indexing is already going wrong, according to the name field, but according to the id field. What could be the problem? select(['name'])->indexBy('id')

Answer 1

And if so?

ArrayHelper::map(Type::find()->select(['id','name'])->all(),'id','name')

Answer 2

Maybe because there is no index on 'name' in the table?
