(Yii2) RangeValidator validation correctness

Question

In app/models/Model this validates

//simulating incorrect user input
//$model->status='some-string';

public function rules()
{
    return [
        ['status', 'in', 'range' => [0]], //asserts true (why?)
      //['status', 'in', 'range' => [0], 'strict' => true], //asserts false (correct)

    ];
}

EDIT: I have updated this question to reflect new insights.

Humh, it seems that if $model->status is input as "some-string", the validator will assert that as equal to 0, unless strict mode is used. So the issue is not the constant, but the comparision itself. — Decimoseptimo, Jan 13 '17 at 05:56

Please make sure you define your constant inside in model class

 class model extends activeRecord {
const STATUS = 0;
public function rules()
{
    return [
        [['status'], 'in', 'range' => [self::STATUS]],
    ];
}
}

Try this it works for me.....

status is most likely empty at the time of the validation, the internal checks compute to something like:

// non-strict:
null == 0  // this is true

// strict:
null === 0 // this is false

same applies with empty string, see related question
