Why is eachValidator not working?

Question

Yii

Good afternoon,
Tell me about EachValidator in yii2.
I don’t understand how I can pass an array of my values ​​\u200b\u200bto it?
Model

public function rules() {
    return [
        [['field'], 'each', 'in', 'range' => array_keys(static::getAttributes(['field']))]
    ];
  }

Answer 1

3rd parameter of this rule "rule" - defines the validation rules, i.e.:

[['field'], 'each', 'rule' => ['in', 'range' => array_keys(static::getAttributes(['field']))]]
