migration 创建数据表

1.创建模型
php artisan make:model --migration Model/Posts
php artisan make:model --migration Model/Users
2. 1的结果会在migrations下得到创建sql的文件，里面写即可：
public function up()
{
Schema::create(‘types’, function (Blueprint $table) {
$table->increments(‘id’);
$table->string(“name”,“20”)->index()->nullable();
$table->integer(“parent_id”)->nullable();
$table->smallInteger(“status”)->default(0)->nullable();
$table->timestamps();
});
}
public function down()
{
Schema::dropIfExists(‘users’);
}
3.生成数据表
php artisan migrate
