laravel 使用artisan命令新增数据库字

cmd 命令行 到项目目录，不是public那个目录

 D:\Program Files\wamp\www\Book> php artisan make:migration add_machine_type_to_books
 Created Migration: 2013_09_05_104157_add_machine_type_to_books
 Generating optimized class loader

migrations目录下面就会生成一个文件，在里面修改即可

文档可见：http://v3.golaravel.com/docs/database/schema.html

 use Illuminate\Database\Migrations\Migration;

 class AddMachineTypeToBooks extends Migration {

     /**
      * Run the migrations.
      *
      * @return void
      */
     public function up()
     {
         Schema::table('books',function($table){
             $table->integer('machine_type');
             $table->string('lan_ip',100);
             $table->string('remote_ip',100);
         });
     }

     /**
      * Reverse the migrations.
      *
      * @return void
      */
     public function down()
     {
         Schema::table('books',function($table){
             $table->drop_column('machine_type');
             $table->drop_column('lan_ip');
             $table->drop_column('remote_ip');
         });
     }

 }

分别执行如下，就可以了

 php artisan migrate:refresh

 php artisan db:seed
