laravel - php artisan migrate fails

Question

I have accidently deleted a database migration table and I have to rollback my changes. This ends up failing. When I load the items view I get the following error.

QueryException in Connection.php line 669: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'ushop.items' doesn't exist (SQL: select * from items)

r I have done some research and I have found this and I get the following upon running composer dump-autoload

PHP Fatal error: Class 'Item' not found in /home/thomas/ushop/vendor/laravel/framework/src/Illuminate/Database/Migrations/Migrator.php on line 336

[Symfony\Component\Debug\Exception\FatalErrorException]
Class 'Item' not found

I hope this question hasn't been answered before, but I'm not having much luck so far.

It's because you've manually deleted a table in the database so right now the table is not available there but when you try to rolling back the framework trys to undo the migration and hence it looks for the table in the database you've deleted manually so the error occurs. Why it looks for the table because in the down method of your migration file you've something like this:

Schema::drop('table_name');

So, it trys to delete the already deleted table from the database but it couldn't find and in your migrations table there is a record for every table you've migrated so you can either manually delete all tables and migrate from the beginning or disable the down (By commenting the drop statement) method temporarily so down method will do nothing in that migration file when you roll back. If you disable the down method temporaarily re-enable the down method again. It's a hack-ish way to fix the problem tho.

Alternatively, you can add a check in your down method in every migration file or just the deleted table's migration file by checking if the table exists then drop it, for example:

public function down()
{
    if (Schema::hasTable('table_name')) {
        Schema::drop('table_name');
    }
}

Hope you've got the idea.
