When searching for the first record, you can perform some actions

When searching for the first record, you want to perform some actions, when you don't find it. firstOrFail() throws a 404 Exception.

You can use firstOr(function() {}) instead. Laravel got your covered

$book = Book::whereCount('authors')
            ->orderBy('authors_count', 'DESC')
            ->having('modules_count', '>', 10)
            ->firstOr(function() {
                // The Sky is the Limit ...
 
                // You can perform any action here
            });
