Laravel - 如何保存多行

Question

我有这个存储方法：

    public function store(Requests\OfferRequest $request)
        {
    $start = $request->input('from'); // 04/24/2016 12:00 AM
    $end = $request->input('to); // 07/24/2016 12:00 AM

                $auction = new Auction($request->all());
                Auth::user()->auctions()->save($auction);
//how to get saved auction ID ?
    }

现在我需要在 Offer 表中保存从 $start 到 $end 的每一天的空记录...只需将已保存拍卖的 id 放在 offer 表中的 auction_id 中...

我可以将其保存在一个查询中还是需要使用 for 循环？最好的方法是什么？

改用这种方式：

//how to get saved auction ID ?
$auction = new Auction();
$auction->fill($request->all());
$auction->user_id = \Auth::user()->id;
$auction->save();
$auction_id = $auction->id;

$dStart = new DateTime($start);
$dEnd   = new DateTime($to);

// Will loop through everyday from $dStart to $dEnd
while ($dStart < $dEnd) {        
    // current date of the loop formated for db use
    $date = $dStart->format('Y-m-d');

    // Code to insert date to Offer 


    $dStart->add(new DateInterval("P1D"));
}
