Laravel 使用insert插入数据，字段created_at为0000？

据官方文档的说明，使用Eloquent ORM，插数据库的时候可以自动生成created_at，updated_at，代码如下：
Model里的代码：

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Notice extends Model
{
    protected $guarded = [];

    //获取部门名称
    public function fromDep(){
       return $this->belongsTo('App\Models\Department','from','id');
    }

    public function toDep(){
        return $this->belongsTo('App\Models\Department','to','id');
    }

    public function toUser(){
        return $this->belongsTo('App\User','create_user','id');
    }
}

新增的代码

public function store(Request $request)
    {
        $data = $request->only(['title','sort','level','from','content','document']);
        $data['creater'] = Auth::user()->id;
        if(Notice::insert($data)){
            return ResponseLayout::apply(true);
        }else{
            return ResponseLayout::apply(false);
        }
    }

插入一条数据，数据库中created_at和updated_at字段为0000-00-00 00:00:00。

原因分析：原生的插入语句，Laravel是不会自动帮你插入created_at和updated_at字段的。

解决方法

• create

public function store(Request $request)
    {
        $data = $request->only(['title','sort','level','from','content','document']);
        $data['creater'] = Auth::user()->id;
        if(Notice::create($data)){
            return ResponseLayout::apply(true);
        }else{
            return ResponseLayout::apply(false);
        }
    }

• save

public function store(Request $request)
    {
        $data = $request->only(['title','sort','level','from','content','document']);
        $data['creater'] = Auth::user()->id;
        $notice = new Notice($data);
        if($notice->save()){
            return ResponseLayout::apply(true);
        }else{
            return ResponseLayout::apply(false);
        }
    }
