Laravel: @foreach 不渲染内容

Question

我正在创建一个简单的@foreach，但由于某种原因它被完全忽略了。我确保数据存在。我 var_dumped 在控制器和视图中都存在，变量确实存在。

控制器代码：

public function create(Request $request)
    {
        $dawrat = Dawra::all();
        $ainshams = University::where('name', '=', 'عين شمس')->first();

        $faculties = Faculty::where('university_id', '=', $ainshams->id);

        return view('createDawra', ['faculties' => $faculties]);
    }

我的看法：

<div class="btn-group" data-toggle="buttons">
@foreach ( $faculties as $faculty)
    <label class="btn btn-danger " id="collg1">
        <input type="checkbox" autocomplete="off">{{ $faculty->name }}
    </label>
@endforeach
</div>

Answer 1

尝试添加 ->get():

$faculties = Faculty::where('university_id', '=', $ainshams->id)->get()

来自 Laravel Eloquent Retrieving Models Docs:

Since each Eloquent model serves as a query builder, you may also add constraints to queries, and then use the get method to retrieve the results
