カラムのbudgetカラム複数合算したtotalというアクセサを増やしてみる。

<?php

namespace App\Http\Models;

use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Model;

/**
 * リレーション
 *
 * @return Illuminate\Database\Eloquent\Collection
 */
class DepartScore extends Model
{
    protected $table = 'tb_department_score';
    protected $primaryKey = 'department_score_id';

    protected $fillable = [
        'department_id',
        'year',
        'period',
        'budget1',
        'budget2',
        'budget3',
        'budget4',
        'budget5',
        'budget6',
        'budget7',
        'budget8',
        'budget9',
        'budget10',
        'budget11',
        'budget12',
    ];

    $appends = ['total_budget'];

    public function getTotalBudgetAttribute() {
        return $this->budget1
               + $this->budget2
               + $this->budget3
               + $this->budget4
               + $this->budget5
               + $this->budget6
               + $this->budget7
               + $this->budget8
               + $this->budget9
               + $this->budget10
               + $this->budget11
               + $this->budget12;
    }
}

• get<プロパティ名>Attribute()で定義
• $appendsも定義する
  $appendsで定義しておくとオブジェクトでの取得を毎回してくれます。

アクセスする

$departScore = new DepartScore();
$departScore->total_budget;

->totalでアクセスできるようになる
