laravel: 调试打印sql

一，代码:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;

class ReadLogModel extends Model
{
    use HasFactory;

    //定义关联的数据表
    protected $table = 'sms_log';

    //定义主键
    protected $primaryKey = 'log_id';

    // 时间字段是否自动管理(created_at 和 updated_at字段)
    public $timestamps  = false;

    // 下面即是允许入库的字段，数组形式，例如:name age sex三个字段允许入库
    protected $fillable = ['*'];

    //添加一条记录
    public function addOne($row) {

        DB::enableQueryLog(); //使支持查询日志
        $model = $this->create($row);
        print_r($model.":<br/>");
        $id = $model->log_id;
        dd(DB::getQueryLog());  //打印出来
        return $id;
    }
}
