您好，我有一个总共有10行的表，其中6行有ID 1行，4行有ID 2行.我想只计算ID 1行的行，但我的代码总共计算了所有行.这是我的代码:
$clientOrder = clientHasOrder::where('order_id', $id)->firstOrFail();
$rowCount = $clientOrder->count();
dd($rowCount);
如果代码工作正常，我应该得到6行和特定的$id行，但这段代码给出了表中总共10行.
如果我做dd(clientHasOrder::all());，我会得到:
这是详细的结果，如您所见，我得到了10个结果，但我只需要6行具有特定ID
