Hi, I'm using this https://docs.phalcon.io/en/latest/api/Phalcon_Mvc_Model_Validator_Uniqueness.html to check in the databse if an email already exist but I can't get the error message "Value of field 'email' is already present in another record". It works but I can't get the message of $this->flash->error($user->getMessages()); because this retuns me "Array". Do you have a solution for that ?
