数据模型

数据模型

数据模型是软件的重要组成部分，基于场景化需求二次封装了 Model 模型。

• 模型基类 app/Models/Model.php

  <?php
  namespace App\Models;
  use Illuminate\Database\Eloquent\Model as Eloquent;
  use App\Models\Traits\HasDateTimeFormatter;
  class Model extends Eloquent{
      use HasDateTimeFormatter;
      public $timestamps = false;
      protected $guarded=[];
  }
  
  
• 时间序列化 app/Models/Traits/HasDateTimeFormatter.php

  <?php
  namespace App\Models\Traits;
  use DateTimeInterface;
  trait HasDateTimeFormatter{
      protected function serializeDate(DateTimeInterface $date){
          return $date->format($this->dateFormat ?: 'Y-m-d H:i:s');
      }
  }
  
• 日期转换 app/Models/Casts/DateStamp.php

  <?php
  namespace App\Models\Casts;
  use Illuminate\Contracts\Database\Eloquent\CastsAttributes;
  class DateStamp implements CastsAttributes{
      public function get($model, $key, $value, $attributes){
          return date("Y-m-d",$value);
      }
      public function set($model, $key, $value, $attributes){
          return strtotime($value);
      }
  }
  
• 时间转换 app/Models/Casts/TimeStamp.php

  <?php
  namespace App\Models\Casts;
  use Illuminate\Contracts\Database\Eloquent\CastsAttributes;
  class TimeStamp implements CastsAttributes{
      public function get($model, $key, $value, $attributes){
          return date("Y-m-d H:i:s",$value);
      }
      public function set($model, $key, $value, $attributes){
          return strtotime($value);
      }
  }
  
• 示例模型

  <?php
  namespace App\Models;
  use App\Models\Casts\TimeStamp;
  class Log extends Model{
      protected $casts = [
          'time' => TimeStamp::class,
      ];
  }
