刷新时,laravel不会在“migrations”表中创建记录

laravel-migrations eloquent laravel

我每次跑步都有个棘手的问题 php artisan migrate:refresh --seed 这个 migrations 表为空,但应在迁移后添加初始迁移记录: 2018_05_02_114819_add_initial_migration

这是我的迁移代码(它是旧数据库架构的导入):

<?php

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

class AddInitialMigration extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        if(!Schema::hasTable('users')){
            DB::unprepared(File::get(database_path('sam.sql')));
        }
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        DB::statement('SET FOREIGN_KEY_CHECKS=0');

        foreach (DB::select('SHOW TABLES') as $table) {

            $table_array = get_object_vars($table);
            if($table_array[key($table_array)] !== 'migrations'){
                DB::statement('DROP TABLE ' . $table_array[key($table_array)]);
            }

        }

        DB::statement('SET FOREIGN_KEY_CHECKS=1');
    }
}
