What is the laravel 5 error with the migrate:refresh command?

Question

Laravel

Mistake

[Symfony\Component\Debug\Exception\FatalThrowableError]
Fatal error: Class 'CreatePhotosTable' not found

Made migrate, it was created in a DB. Added a field to another users table and when migrate:refrash gives this error

Answer 1

$ composer dumpautoload -o
Frequent problem. The command above solves it.

Answer 2

The migration class was not included in autoload, that is, Composer does not see it, respectively, Laravel too. The console command helps composer dump -oafter creating a new migration.
