尝试读取bool上的属性"slg"

Question

我在显示数据库中的数据时遇到问题，我从数据库中获取数据，但显示不起作用。我的模型是空的。谢谢

路线web.php

Route::get（'/turnaje/{slg}'，[regonController::class，'show']）；

show.blade.php

<form action="{{ url('turnaje/choose')}}" method="post">
        @csrf <!-- {{ csrf_field() }} -->
        <label for="cars">Choose a car:</label>

        <select name="region_id" onchange="this.form.submit()">
            <option value="vsetky-kraje">Všetky kraje</option>
            @foreach ($regions as $region)
                @foreach ($regions_list as $region_list)
                    <option value="{{ $region_list }}" {{ ($region_list->slug == $region->slug) ? 'selected' : '' }}>{{ $region_list->title }}</option>
                @endforeach
            @endforeach
        </select>
    </form>

我的地区

    public function show($slug)
{
    return view('tournaments.show', [
        'regions' => Region::where('slug', $slug)->firstOrFail(),
        'regions_list' => Region::all(),
    ]);
}

Answer 1

删除第一个Foreach语句，并将变量重命名为$区域：

<form action="{{ url('turnaje/choose')}}" method="post">
        @csrf <!-- {{ csrf_field() }} -->
        <label for="cars">Choose a car:</label>

        <select name="region_id" onchange="this.form.submit()">
            <option value="vsetky-kraje">Všetky kraje</option>
           
                @foreach ($regions_list as $region_list)
                    <option value="{{ $region_list }}" {{ ($region_list->slug == $region->slug) ? 'selected' : '' }}>{{ $region_list->title }}</option>
                @endforeach
            
        </select>
    </form>

在控制器中：

    public function show($slug)

{
    return view('tournaments.show', [
        'region' => Region::where('slug', $slug)->firstOrFail(),
        'regions_list' => Region::all(),
    ]);
}
