Model custom client side validation

I have created a custom validator class named "EndTimeValidator" in common\components namespace.

Code:

namespace common\components;

use yii\validators\Validator;

class EndTimeValidator extends Validator
{
    public function init()
    {
        parent::init();
        $this->message = 'Event EndTime must be greater than StartTime.';
    }

    public function validateAttribute($model, $attribute)
    {
        $startDate = $model->StartDate;
        $endDate = $model->EndDate;

        $startTime = $model->StartTime;
        $endTime = $model->EndTime;

        if( ($startDate == $endDate) &&  $startTime != "" && $endTime != ""  )
        {
            if( strtotime($endTime) < strtotime($startTime) )
            {
                $this->addError($attribute, $this->message);
            }
        }
    }

    public function clientValidateAttribute($model, $attribute, $view)
    {
        $startDate = $model->StartDate;
        $endDate = $model->EndDate;

        $startTime = $model->StartTime;
        $endTime = $model->EndTime;

        if( ($startDate == $endDate) &&  $startTime != "" && $endTime != ""  )
        {
            if( strtotime($endTime) < strtotime($startTime) )
            {
                return <<<JS
    messages.push($this->message);
JS;
            }
        }
    }
}

And in model I first included that path and defined the validation as below:

use common\components\EndTimeValidator;

['EndTime', EndTimeValidator::class],

Question updated:

But it is giving me below exception:

Call to a member function getAttributeLabel() on a non-object

I have referred to this link. Am I doing anything wrong? Please guide me. Thanks!

It was a silly mistake. But I will keep this question as it may help someone.

The error was due to the following line in the validateAttribute function

$this->addError($attribute, $this->message);

Replace the above line with:

$model->addError($attribute, $this->message);

Use:

use common\components\EndTimeValidator;

/** .... */

['EndTime', EndTimeValidator::class],
