laravel 5顯示相關數據以登錄用戶

Question

在Laravel 5項目中，我試圖向登錄的用戶顯示其課程包的詳細信息。 我正在嘗試使用where子句來獲取所需的信息。 看來我無法從要返回的集合中獲取關系數據。 我迷路了，需要一些指導。 我似乎找不到與此類問題有關的任何信息。

當前錯誤：未定義的屬性：Illuminate \\ Database \\ Eloquent \\ Collection :: $ players（查看：/home/ubuntu/workspace/resources/views/auth/account/mylessonhours.blade.php）

我的控制器：

 public function getMyLessonhours(Lessonhours $lessonhours, Packages $packages)
{
    $packages = Packages::all();
    $lessonhours = Lessonhours::whereHas('players', function($q)
    {
        $q->where('users_id', '=', Auth::user());
    })->with('players')->get();
    return view('auth.account.mylessonhours', compact('lessonhours'), compact('packages'));
}

我的關系：用戶：

 public function players()
{
    return $this->hasMany('App\Players', 'users_id');
}

玩家：

 public function users()
{
    return $this->belongsTo('App\User', 'users_id');
}

Lessonhours：

public function players()
{
    return $this->belongsTo('App\Players', 'players_id');
}

public function packages()
{
    return $this->belongsTo('App\Packages', 'packages_id');
}

public function hoursused()
{
   return $this->hasMany('App\Hoursused', 'lessonhours_id');
}

而視圖失敗的部分

 <h3>{{ $lessonhours->players->getFullName($lessonhours->players_id) }}</h3>  
                        {{ $lessonhours->players->gender }}<br>
                        <a href="#" class="btn btn-default btn- pull-right">
                                   <span class="glyphicon glyphicon-pencil" aria-hidden="true"></span> 
                                   Edit {{ $lessonhours->players->getFullName($lessonhours->players->id) }}</a>
                       Birthdate: {{ $lessonhours->players->birthdate->format('m-d-Y') }}<br>

                       Family: {{ $lessonhours->players->users->famname }}<br>
                       <hr>

謝謝你的幫助。

UDATE：經過dd（$ lessonhours）； 我在集合中得到了以下數據，該數據確實顯示了所需的信息，我只是繼續收到上面的“未定義”錯誤：

      #with: []
      #morphClass: null
      +exists: true
      +wasRecentlyCreated: false
    }
  ]
}

更新：錯誤發生在下面的行：

 <h3>{{ $lessonhours->players->getFullName($lessonhours->players_id) }}</h3> 

該代碼有效，但我只想要一個父記錄。

Answer 1

您需要從用戶對象獲取ID，因此將查詢更改為：

$lessonhours = Lessonhours::whereHas('players', function($q) {
        $q->where('users_id', Auth::user()->id);
    })->with('players')->get();

Answer 2

由於get()方法返回集合數組，而與結果數無關。 如果只期望單個結果，則可以使用first()方法。

$lessonhours = Lessonhours::whereHas('players', function($q)
    {
        $q->where('users_id', '=', Auth::user()->id);
    })->with('players')->first();

或在視圖中渲染時for each循環。
