如何在codeigniter中回滚迁移？

Question

I've been able to create and run migrations in Codeigniter but I've not been able to rollback my migration. Can anyone help me how to rollback migration in codeigniter?

use Illuminate\Database\Capsule\Manager as Capsule;

class Migration_Create_language extends CI_Migration {

public function up() {
    Capsule::schema()->create('languages', function($table){
        $table->increments('id');
        $table->string('name', 120);
        $table->string('country', 120);
        $table->string('country_code', 20);
        $table->enum('status', array('0','1'))->default('0');
        $table->timestamps();
    });
}

/*
* Sample function for rolling back the above action
*/
public function down()
{
    Capsule::schema()->drop('languages');
}

}

Can you post your migration code?

There's a method called downin every migration. That's what it's executed when the migration happens downwards. Make sure that you have your sql statements in down, for example, to destroy a table. Then, load the migration version that you want.
