我试图在livewire中创建一个系统，允许用户添加/编辑房屋，但也允许在每个房屋中添加/编辑房间。
我创建了house和room模型以及createHouse和嵌套room刀片文件。房子的细节得到保存，但房间没有。我相信我需要使用$emitUp将roomid和name参数传递回House组件，但我显然做错了什么。

                <div class="w-1/2 pr-4">
                        <div class="mb-4">
                            <label for="input1">Address1:</label>
                            <input type="text" id="input1" placeholder="Enter Address" wire:model.defer="address1">

                    </div>
                    <div class="w-1/2">
                        <h3 class="mb-2">Rooms</h3>
                        @foreach ($rooms as $key => $room)
                            @livewire('room-show', [$room])
                        @endforeach
