laravel5.3软删除

1、首先在模型中要使用SoftDeletestrait,该trait为软删除提供一系列相关方法，具体可参考源码Illuminate\Database\Eloquent\SoftDeletes ，此外还要设置$date属性数组，将deleted_at置于其中：

<?php

namespace App\Model\Backend;

use App\Http\Response;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Request;

class User extends Model
{
    use SoftDeletes;

    protected $table = 'users'; //表名
    protected $primaryKey = 'id'; //主键
    protected $datas = ['deleted_at'];

2、向数据库中的相应数据表添加 delete_at 字段

#生成一个迁移文件
php artisan make:migration add_deleted_at_to_users_table --table=users        
#执行迁移文件
php artisan migrate

<?php 
use Illuminate\Database\Schema\Blueprint; 
use Illuminate\Database\Migrations\Migration; 

class AlterPostsDeletedAt extends Migration { 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() { 
        Schema::table('posts', function (Blueprint $table) { 
            $table->softDeletes(); 
        }); 
    } 

    #模型里面执行delete方法就行了
    self::whereIn('id', $ids)->delete(); //删除用户
    withTrashed() 显示所有数据
    onlyTrashed() 显示删除数所
    restore()还原数据
