SQLSTATE[23000]: 完整性约束冲突: 1452 无法添加或更新子行: 外键约束失败

我使用习语+苗条

我意识到以下更新查询，但我在控制台phpmyadmin中尝试并且它可以工作。

update empleado set `nieempleado`='11111', nombre="Mickael", apellido1="aaa", apellido2="bbb", email="ma@gmail.com", puesto=0 where id = 1

但在成语错误 SQLSTATE[23000]

怎么了？

if(count($error)==0)
        {
            $empleado = ORM::for_table('empleado')->find_one($id);
            $empleado->nieempleado = $nie;
            $empleado->nombre = $nombre;
            $empleado->apellido1 = $apellido1;
            $empleado->apellido2 = $apellido2;
            $empleado->email = $email;
            $empleado->puesto = $puesto;   
            if(!empty($telefono))
            {
                $empleado->telefono = $telefono;
            }
            if($usuario!=='')
            {
                $empleado->usuario_idusuario = $usuario;
            }  
            $empleado->save();
            $app->redirect($app->urlFor('employeeList'));
        }

我的桌子是用法的：

CREATE TABLE IF NOT EXISTS `usuario` (
           `id` int(11) UNSIGNED AUTO_INCREMENT,
           `username` varchar(45) NOT NULL,
           `contrasenia` varchar(255) NOT NULL,
           `email` varchar(45) NOT NULL,
           `admin` tinyint(1) UNSIGNED NOT NULL DEFAULT 0,
            PRIMARY KEY (`id`)) 
            ENGINE = InnoDB;

和恩普利多

CREATE TABLE IF NOT EXISTS `empleado` (
           `id` int(11) UNSIGNED NOT NULL AUTO_INCREMENT,
           `nieempleado` VARCHAR(10) NOT NULL,
           `nombre` VARCHAR(45) NOT NULL,
           `apellido1` VARCHAR(50) NOT NULL,
           `apellido2` VARCHAR(50) NOT NULL,
           `email` VARCHAR(100) NOT NULL,
           `telefono` VARCHAR(10) NULL,
           `puesto` int(11) NOT NULL,
           `usuario_idusuario` int(11) UNSIGNED,
            PRIMARY KEY (`id`),
            INDEX `fk_empleado_usuario1_idx` (`usuario_idusuario` ASC),
            CONSTRAINT `fk_empleado_usuario_id_fk`
            FOREIGN KEY (`usuario_idusuario`)
            REFERENCES `usuario` (`id`)
            ON DELETE CASCADE
            ON UPDATE CASCADE
            )ENGINE = InnoDB;

我收到以下错误：
