Yen sampeyan type-hint model (User $user) lan route parameter name cocog ({user}), Laravel otomatis fetch model kanthi id-ne lan inject — ngganti manual User::findOrFail($id) sing biasane sampeyan tulis, lan bali 404 otomatis yen record ora ana.
// ❌ without — manual fetching and 404 handling
public function show($id) {
$user = User::findOrFail($id); // fetch + 404 by hand
return $user;
}
// ✅ with route model binding — Laravel does it for you
public function show(User $user) { // injected, 404 handled automatically
return $user;
}
// bind by a column other than id (e.g. a slug)
Route::get('/posts/{post:slug}', ...); // resolves Post by its `slug` column
// or define a custom key on the model:
public function getRouteKeyName() { return 'slug'; }
Default-ne bind kanthi primary key, nanging sampeyan bisa bind kanthi kolom apa (contone slug) — useful kanggo friendly URLs.
// ensure the comment belongs to the post (scoped to the parent)
Route::get('/posts/{post}/comments/{comment}', ...); // auto-scoped in Laravel
