The model attributes validation do not use custom validator.

[mit40]

What steps will reproduce the problem?

Class Test extends Model
...
 public function unique($attribute){...}
...
    public function rules()
    {
        return [
         ....
            ['propertyName', 'unique']
        ];
    }
...

see
file yiisoft/yii2/validators/Validator.php

 function createValidator
 line: 214     elseif (!isset(static::$builtInValidators[$type]) && $model->hasMethod($type))    // incorrect logic

What is the expected result?

use overwritten method

see version 2.0.9 :

 if ($type instanceof \Closure || $model->hasMethod($type)) {

What do you get instead?

it uses base method

yeah, based on v2.0.9, you can override built in
but after v2.0.36, you cannot override builtin validator, because of #14370 issue
so you may change the custom name validator

Will changing the line 214 to

} elseif ($model->hasMethod($type)) {

fix this issue?

It was forbidden to override default validator while solving the issue: #14499 If it can be fixed without breaking that case again we can have it.
