在Laravel 5.1 DB中重命名列时的例外情况

i just did a migration in Laravel. I noticed that in the users table there are several columns: id, name, email and so on. I changed the the column named "name" to "username" and i put it as a unique column. Now when I start my app and try to register i get 2 exeptions: QueryExpetion and PDOExeption. I thought that I should change something in the Builder.php bou there is no such thing in there. These are the error I got. What do I need to change?!
