laravel如何仅恢复软删除删除的最后一个项目

我有一个购物车表，可以保存所有客户订单

+------------------------------------------------------------------------------+

|id |用户id |产品|创建|更新|删除|在|

+------------------------------------------------------------------------------+

当用户软删除时，我们希望软删除其卡中的所有项目

当用户想要恢复时，我们想要恢复上次软删除的项目

我可以实施它

这是我的代码中的revert函数：

public function revertBackDeletedItems(Request $request)
{
    $user = apiGetUser();
    if ($user == null) {
        return apiAbort(401);
    }

    $purchaseCartCount = $user->cart()->onlyTrashed()->count();
    if ($purchaseCartCount == 0) {
        return [
            'success' => false,
            'message' => 'no items in card '
        ];
    }

    $purchaseCartDateTimeInLatestDelete = $user->cart()->onlyTrashed()->orderBy('id', 'desc')->first()['deleted_at'];

    $purchaseCarts = PurchaseCart::onlyTrashed()->where('user_id', $user->id)->where('deleted_at', $purchaseCartDateTimeInLatestDelete)->get();
    foreach ($purchaseCarts as $key => $purchaseCart) {
        $purchaseCart->restore($purchaseCart->id);
    }
    return ['success' => true];
}

这是只删除上次删除的项目的函数

 public function deleteLastTrashed(Request $request)
{
    $user = apiGetUser();
    if ($user == null) {
        return apiAbort(401);
    }

    $purchaseCartCount = $user->cart()->onlyTrashed()->count();
    if ($purchaseCartCount == 0) {
        return [
            'success' => false,
            'message' => 'no items in card '
        ];
    }

    $purchaseCartDateTimeInLatestDelete = $user->cart()->onlyTrashed()->orderBy('id', 'desc')->first()['deleted_at'];

    $purchaseCarts = PurchaseCart::onlyTrashed()->where('user_id', $user->id)->where('deleted_at', $purchaseCartDateTimeInLatestDelete)->get();
    foreach ($purchaseCarts as $key => $purchaseCart) {
        $purchaseCart->forceDelete($purchaseCart->id);
    }
    return ['success' => true];
}

我怎样才能以更好的方式被删除

这不是一个干净的代码

我需要更好的方法来实现此算法

您可以尝试以下方法：

在carts表中添加新字段已被删除，并且是最近的，所以无论何时用户将删除，设置为删除=1；要删除的项目的最近值为1，其他项目的最近值为0； 在恢复获取期间，已更新的项目=1；而save is_deleted=1

您就快到了：

public function deleteLastTrashed(Request $request)
{
    $user = apiGetUser();
    if ($user == null) {
        return apiAbort(401);
    }

    $purchaseCartCount = $user->cart()->onlyTrashed()->count();
    if ($purchaseCartCount == 0) {
        return [
            'success' => false,
            'message' => 'no items in card '
        ];
    }

    // here you know that user has at least one soft deleted cart
    $userLastCartSoftDeleted = $user->cart()->onlyTrashed()->orderBy('deleted_at', 'desc')->first();

    $userLastCartSoftDeleted->forceDelete();

    return ['success' => true];
}
