我的遷移文件如下。

<?php 

use Illuminate\Support\Facades\Schema; 
use Illuminate\Database\Schema\Blueprint; 
use Illuminate\Database\Migrations\Migration; 

class UpdateRelationshipsForEmployee extends Migration 
{ 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     // 
     Schema::table('employee',function ($table){ 
      $table->integer('retail_id')->unsigned()->index()->change(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::table('employee', function ($table){ 
      $table->integer('retail_id')->change(); 
     }); 
     // 

    } 
}

剛落，總的數據庫，然後運行命令 PHP工匠遷移：刷新--seed

你也可以保持你的數據庫。 只需複製模型和遷移信息即可。 然後刪除。 刪除重建模型和表格後。

現在。去你的數據庫遷移表。刪除員工行。 現在。刪除你的員工表。

現在只要終端命令PHP工匠遷移
