.
1 $model = App\Flight::findOrFail(1);

3 $model = App\Flight::where('legs', '>', 100)->firstOrFail();
If the exception is not caught, a 404 HTTP response is automatically sent back to the user, so it is

.
1 Route::get('/api/flights/{id}', function ($id) {
2 return App\Flight::findOrFail($id);
3 });
Retrieving Aggregates
Of course, you may also use the query builder aggregate functions such as count, sum, max, and
the other aggregate functions provided by the query builder. These methods return the appropriate
scalar value instead of a full model instance:
.
1 $count = App\Flight::where('active', 1)->count();
2
3 $max = App\Flight::where('active', 1)->max('price');
