Question

我正在使用laravel开发一个问题答案应用程序，我想在每个问题下显示该特定问题的所有答案。我面临的问题是我无法改变视图以在相应的问题下显示答案，因为在laravel视图中无法匹配ID！

我的观看代码：

@section('list-questions-answers')
    <ul>
        @foreach($listQuestions as $q)
            <li><a href="{{url('/questions/'.$q->question_id)}}">{{ $q->question }}</a></li>
            @foreach($listAnswers as $a)
                <ul>
                    <li>{{ $a->answer }}</li>
                </ul>
            @endforeach
        @endforeach
    </ul>
@endsection

答案的模型

public function User()
{
    return $this->belongsTo('App\User');
}
public function questions()
{
    return $this->belongsTo('App\questions','answer_id');
}
public function scopefetchAnswers($query)
{
    return $query->select('answer')->where('people_id','<>',Auth::id())->get();
}

问题的模型：

protected $table='questions';
protected $primaryKey='question_id';
protected $fillable = [
   'question', 'created_at','details'
];
//protected $hidden=['question_id'];
public function setUpdatedAtAttribute($value) {}
public function User() {
    return $this->belongsTo('App\User');
}
public function answers()
{
    return $this->hasMany('App\answers','question_id');
}
public function scopefetchQuestions($query) {
    return $query->select('question','question_id')->where('people_id','=',Auth::id())->get();
}

所有内容都显示在dashboard.blade.php上，它在仪表板控制器上运行

class Dashboard extends Controller
{
    public function index(){

        $listQuestions=questions::latest('created_at')->fetchQuestions();
        //$listAnswers=answers::groupBy('question_id')->fetchAnswers();
        $listAnswers=answers::fetchAnswers();
        return view('forms.question',compact('listQuestions','listAnswers'));
    }
}

您提取问题的查询应为：

$listQuestions= Question::where('people_id', '=', Auth::id())
                            ->with(['answers' => function($q) {
                                $q->where('people_id', '<>' ,Auth::id());
                             }])
                            ->get();

您的视图文件应为：

section('list-questions-answers')
    <ul>
        @foreach($listQuestions as $q)
            <li><a href="{{url('/questions/'.$q->question_id)}}">{{ $q->question }}</a></li>
            @foreach($q->answers as $a)
                <ul>
                    <li>{{ $a->answer }}</li>
                </ul>
            @endforeach
        @endforeach
    </ul>
@endsection
