在子组件laravel livewire问题中访问和保存父数据

如何解决在子组件laravel livewire问题中访问和保存父数据

我无法访问子组件中的父数据字段，当我将其添加为子组件中的公共属性时，它会擦除​​表单输入中的值。当我在子组件中设置公共$ amount属性时，金额字段将返回空值。

父视图

<div>
    @foreach ($products as $product)
        @livewire('orders',['product'=> $product],key($product->id))
    @endforeach
</div>

子视图

<div class="mt-8">
    <div class="max-w-sm rounded overflow-hidden shadow-lg bg-white">
        <div class="px-6 py-4">
            <div class="font-bold text-xl mb-2 ">{{$product->id}}</div>
            <hr><br>
            <p class="text-gray-700 text-base">

            <div class="font-bold text-lg mb-2">
                {{$product->amount}}
            </div>

            <div class="relative">
                <select wire:model="period" name="period"
                    class="block appearance-none w-full bg-white border border-gray-400 text-gray-700 py-3 px-4 pr-8 rounded leading-tight focus:outline-none focus:bg-white focus:border-gray-400">
                    <option value="5">5 Days</option>
                    <option value="7">7 Days</option>
                    <option value="10">10 Days</option>
                </select>
                @error('period')
                    <p class="mt-2 text-sm text-red-600">{{ $message }}</p>
                @enderror
            </div>
            <br>
            <div class="relative">
                <input wire:model="amount"
                    class="appearance-none block w-full bg-white text-gray-700 border border-gray-400 rounded py-3 px-4 mb-3 leading-tight focus:outline-none focus:bg-white focus:border-gray-400"
                    type="text" value="{{$product->amount}}">
                @error('amount')
                 <p class="mt-2 text-sm text-red-600">{{ $message }}</p>
                @enderror
            </div>
        </div>
        <div class="px-6 py-4">
            <button wire:click.prevent="save({{$product->id}})"
                class="inline-block bg-purple-700 rounded-full px-3 py-1 text-sm font-semibold text-gray-200 mr-2 transform motion-reduce:transform-none hover:-translate-y-1 hover:scale-110 transition ease-in-out duration-300">
                Bid
            </button>
        </div>
    </div>
</div>

父组件

<?PHP

use Livewire\Component;
use App\Product;
use App\User;

class Products extends Component
{
    public $products;

    public function mount()
    {
        $this->products = Product::all();
    }


    public function render()
    {
        return view('livewire.products');
    }
}

子组件

<?PHP

namespace App\Http\Livewire;

use Livewire\Component;

use App\Product;

class Orders extends Component

    public $product,$period = 5,$productId,$amount;


    public function mount(Product $product)
    {
        $this->product = $product;
    }

    public function save($productId)
    {
        $product = Product::where('id',$productId)->first();
        $product->createOrders([
            'buyer_id' => auth()->user()->id,'product_id' => $this->productId,'period' => $this->period,'order_amount' => $this->amount,]);
    }
