Laravel - Routing - Explicit Binding

You are not required to use Laravel's implicit, convention based model resolution in order to use model binding. You can also explicitly define how route parameters correspond to models. To register an explicit binding, use the router's model method to specify the class for a given parameter. You should define your explicit model bindings at the beginning of the boot method of your RouteServiceProvider class:

use App\Models\User;
use Illuminate\Support\Facades\Route;

 * Define your route model bindings, pattern filters, etc.
 * @return void
public function boot()
    Route::model('user', User::class);

    // ...

Next, define a route that contains a {user} parameter:

use App\Models\User;

Route::get('/users/{user}', function (User $user) {

Since we have bound all {user} parameters to the App\Models\User model, an instance of that class will be injected into the route. So, for example, a request to users/1 will inject the User instance from the database which has an ID of 1.

If a matching model instance is not found in the database, a 404 HTTP response will be automatically generated.
