pickup_contentsテーブルにfruit_idが存在したら422となるバリデーションRuleの例

 

DeleteFruitRequest.php

<?php

namespace App\Http\Requests\CM\Fruit;

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Http\Request;
use App\Rules\CM\Fruit\IsPickUpFruitRule;

        Request $request,
        IsPickUpFruitRule $is_pickup_fruit_rule
    ) {
        parent::__construct();
        $this->fruit_id = $request->fruit_id;
        $this->is_pickup_fruit_rule = $is_pickup_fruit_rule;
    }

    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        $fruit_id = $this->fruit_id;
        return [
            'fruit_id' => [
                'numeric',
                'required',
                $this->is_pickup_fruit_rule,
            ],
        ];
    }

    public function validationData()
    {
        return array_merge($this->request->all(), [
            'fruit_id' => $this->fruit_id,
        ]);
    }
}

validationData()

JSONのキーをfruit_idとしてバリデーションする為の処理

 

rules()

ここでカスタムRuleを割り当ててバリデーションを指定

 

カスタムRule

 

IsPickUpFruitRule.php

<?php

namespace App\Rules\CM\Fruit;

use Illuminate\Contracts\Validation\Rule;
use App\Repositories\Pickup\PickupContentInterface;

class IsPickUpFruitRule implements Rule
{
    public function __construct(
        PickupContentInterface $i_pc
    ) {
        $this->i_pc = $i_pc;
    }

    public function passes($attribute, $value)
    {
        // ピックアップにfruit_idが含まれている場合は422エラー
        $pickup_content = $this->i_pc->findWhere(['fruit_id' => $value]);
        if ($pickup_content != null) {
            return false;
        }
        return true;
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return __('validation_client_administrator.messages.already_pickup_fruit_id');
    }
}

 

passes($attribute, $value)

• trueを返せばバリデーション通過
• falseで422エラーとなる
