SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails

I use idiorm + slim

I realize the following update query, but I try in the console phpmyadmin and it works.

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


but in idiorm error SQLSTATE[23000]

What´s the problem?

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'));
}


My tables are usuario:

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;


and empleado

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;


I get the following error:

Type: PDOException
Code: 23000
Message: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`viversoft`.`empleado`, CONSTRAINT `fk_empleado_usuario_id_fk` FOREIGN KEY (`usuario_idusuario`) REFERENCES `usuario` (`id`) ON DELETE CASCADE ON UPDATE CASCADE)

Answer

Your error means that you're trying to insert a value into the column usuario_idusuario in the empleado table that does not exist in the column id in the usuario table. Without seeing the query that's being run and the table values, I can't give you any more info. You need to ensure any value going into usuario_idusuario exists in id.

Thanks,
