Laravel - getting largest object based on attribute value

问题

I have been trying to get the four highest objects based on an attribute in them.

I can successfully get the one with the highest value by doing the following:

{{ Bid::where('auction_id', '=', $auction->id)->max('bid_amount') }}

Which gets the object which have the highest bid_amount value.

Now I could potentially make a loop and loop all bids through but Laravel must have a smarter way of doing it and I have not been able to find this in their documentation.

You may try this

Bid::where('auction_id', '=', $auction->id)
    ->orderBy('bid_amount', 'DESC')
    ->take(4)
    ->get();
