我專案上使用API Resource實做某一個資料的回傳, 最近分別實現show 和 index 的回傳

首先, 在show 部分的resource 我是這樣寫的

    public function toArray($request)
    {
        $this->giftCustomer->message = $this->giftMessages->gift_customer_message;
        
        $this->receiveCustomer->message = $this->giftMessages->receive_customer_message;

        return [
            .... (以上略)
            "gift"     => new Customer($this->giftCustomer),
            "receive"  => new Customer($this->receiveCustomer),
        ];
    }

而index 顯示列表時我得這樣

    public function toArray($request)
    {
        return [
             .... (以上略)
            "gift"     => collect(new Customer($this->giftCustomer))->merge(['message'=>$this->giftMessages->gift_customer_message]),
            "receive"  =>collect(new Customer($this->receiveCustomer))->merge(['message'=> $this->giftMessages->receive_customer_message])),
        ];

兩者其實customer 的部分都是一樣的

    public function toArray($request)
    {
        return [
            "id"        => $this->id,
            "account"   => $this->account,
            "nickname"  => $this->nickname,
            "message"   => $this->message
        ];
    }

其實我蠻喜歡上面show 部分的寫法,比較簡潔比較好看
但是index 我試過了卻無法正確顯示我要的message,
反而要在外層使用collect()->merge() 才能顯示我要的message

難道 Resouce::collection 和 new Resource() 有一些不一樣
所以才讓我在index 的部分沒辦法按照show 的寫法?

那麼, 我index的部分應該怎麼樣寫會比較好看?

也不知道怎麼打關鍵字,如果有建議的關鍵字可以丟給我好讓我去查看看
