I am doing a news system and I want my url in the following way:
http://web.com/noticias/{id_generado}/
The {id_generado} is an id that I generate using the str_random(10) function.
The problem of the matter is: What happens if two news by chance generate the same {id_generado} ?
How can I check beforehand if that id has already been assigned to another news item and generate a new one? With a do-while?
You can use a validation before saving
Manually Creating Validators
public function store(Request $request)
{
$validator = Validator::make(['id_generado' => 165654165765456], [
'id_generado' => 'required|unique:noticias|max:255'
]);
if ($validator->fails()) {
// Si falla la validacion ...
}
// Si no falla registras en la base ...
}
It would be nice to use the do-while, one of the ways to apply it would be obtaining all the current ids (a single query) and comparing them with the generated one:
$idsActuales = Noticia::pluck('id_generado');
do {
$idNuevo = str_random(10);
} while (in_array($idNuevo, $idsActuales));
// guardar noticia con nuevo id
Noticia::create(['id_generado' => $idNuevo]);
