尝试在 bool 上读取属性“slug”

如何解决尝试在 bool 上读取属性“slug”

我在从数据库显示数据时遇到问题，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

路由 web.PHP

Route::get('/turnaje/{slug}',[RegionController::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>

我的区域控制器

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

解决方法

去掉第一条foreach语句，将变量重命名为$region：

<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(),]);
}
