[PHP] 解决Laravel 使用insert插入数据，字段created_at为0000的问题

<?php
 
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');
  }
}

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);
  }
  }

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);
  }
  }

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);
  }
  }
