Blueprint

سلام میخوام یک متدد در Blueprint بازنویسی کنم. اومدم یک پوشه به نام service داخل app ساختم و یک فایل از کلاس با نام db.php ایجاد کردم که اینم کدش هست.

<?php namespace App\service;

use Illuminate\Database\Schema\Blueprint;

class db extends Blueprint
{
    public function full_time($model = '')
    {
        if (is_array($model)) {
            $ex = explode('|', $model);
            if(in_array('C',$ex)){
                $this->integer('created_at')->default('');
                $this->integer('created_by')->default('');
            }
            if(in_array('U',$ex)){
                $this->integer('update_at')->default('');
                $this->integer('update_by')->default('');
            }
            if(in_array('D',$ex)){
                $this->integer('delete_at')->default('');
                $this->integer('delete_by')->default('');
            }
        } else {
            $this->integer('created_at')->default('');
            $this->integer('update_at')->default('');
            $this->integer('delete_at')->default('');
            $this->integer('created_by')->default('');
            $this->integer('update_by')->default('');
            $this->integer('delete_by')->default('');
        }

    }
}

و داخل مایگریشن اینو اینطور نوشتم:

    public function up()
    {
        Schema::create('users', function (db $table) {
            $table->id();
            $table->string('name',100)->default('');
            $table->string('family',100)->default('');
            $table->char('gender',1)->default('0');
            $table->string('national_code',10)->default('');
            $table->string('photo',255)->default('');
            $table->string('id_number',10)->default('');
            $table->integer('birthday')->default(null);
            $table->full_time('C|U|D');
        });
    }

و کد دستوری php artisan migrate:fresh را میزنم. وخطایی که می ده:

php artisan migrate:fresh
Dropped all tables successfully.
