I'm doing an app in laravel, but I get to a situation where the DB relationship is one to many users - articles, so my problem is that I want to place a limit that users can only add max 5 articles, I've been looking for, but nothing I try to try. I thank you
That type of restrictions is better to work in the logical section of the application, which reduces the number of queries to your database. You can do a simple validation with the function count() of Laravel:
public function store($article) {
$user = auth()->user(); // un usuario, el logueado por ejm
if ($user->articles->count() >= 5) { // condición
return 'Lo sentimos, has alcanzado el máximo permitido (5)' // mensaje
}
else {
// la lógica de tu operación..
}
