laravel 5显示相关数据以登录用户

Question

In a Laravel 5 project I am trying to display to a logged in user the details of their lesson packages. I am trying to use a where clause that gets the desired info. It seems that I can't get relationship data from the collection that I am getting back. I am lost and am requesting some guidance. I can't seem to find any info pertaining to this kind of problem.

The current error: Undefined property: Illuminate\\Database\\Eloquent\\Collection::$players (View: /home/ubuntu/workspace/resources/views/auth/account/mylessonhours.blade.php)

My Controller:

 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'));
}

My Relationships: Users:

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

Players:

 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');
}

And the part of the view that fails

 <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>

Thank you for help.

UDATE: After doing a dd($lessonhours); I got the following data in the collection which does show the desired info, I just continue to get the 'undefined' error above:

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

UPDATE: The error occurs with the following line:

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

The code works, but I only want one parent record.

Answer 1

You need to get an ID from user object, so change you query to:

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

Answer 2

Since get() method returns the array of collection irrespective of number of results. If you are expecting only single result you can use first() method.

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

Or use for each loop while rendering in the view.
