Laravel มีปัญหาการสร้าง Model ใหม่ผ่าน Sentry แต่ปรากฏว่าไม่พบ

<?php
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\Reminders\RemindableTrait;
class User_Sentry extends Cartalyst\Sentry\Users\Eloquent\User {

protected $table = 'users';

public static $signup_rule = array(
'first_name'	=> 'required|min:6|unique:users',
'last_name' => 'required|min:6',
'email' => 'email|required|min:6|unique:users',
'password' => 'required|min:6',
're_password' => 'requied|same:password'

);
}
