Show custom error message on screen

[Vincent]

Is there a way to show custom error message on screen when the validation in the before save script not passed?

Hello.
Use "use Espo\Core\Exceptions\BadRequest;" in header and in script use "
throw new BadRequest('error'); " sam thing with Error or NotFound.

Everything you can find in EspoCRM repo.

Hello

throw new BadRequest('error');"? Thanks.

emillod, thank you.
I have update the custom\Espo\Custom\Repositories\MyEntity.php following your suggestion. It can now show the custom error message on screen

Hi
I have created a TEST entity. In the system generated custom\Espo\Custom\Repositories\TEST.php, i added a beforeSave function in the file. Code is as follows:

<?php

namespace Espo\Custom\Repositories;
use Espo\Core\ORM\Entity;
use Espo\Core\Exceptions\Error;
use Espo\Core\Exceptions\Conflict;

class TEST extends \Espo\Core\Templates\Repositories\Base
{
protected function beforeSave(Entity $entity, array $options = [])
{
parent::beforeSave($entity, $options);
throw new Error('it is a custom error');
}

}
}

An error message 'it is a custom error' is shown on the screen when i save the record of TEST entity
