Answer 1

Your attendance relationship model is wrong, it should be in a relation with user model class and not with itself like you currently have:

Attendance Model:

public function users()
{
    return $this->hasMany('App\Attendance','aid','aid');
}

Should be pointing to user model:

public function users()
{
    return $this->hasMany('App\Users');
}

Since when u eager load the user it should return user data also.

Answer 2

Your relationship is wrong. It should be a User hasMany attendances and not the other way round.

Attendance Model:

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

User Model:

public function attendances(){
    return $this->hasMany('App\Attendance', 'user_id');
}

Then with your $userId , do this:

$attendances = App\User::find($userId)->attendances;

In response to your question:

I suppose you already have your $userId right?. In your UserController, you can do:

$user = User::find($userId);    //Find the user that has that id

Let's assume you want to use it in your view. Then do this:

return view('view-name', ['user' => $user]);    //pass $user to view

In your view, do this:

<ul>
    @foreach($user->attendances as $attendance)      <!--$user->attendances - You remember this?-->
        <li>{{ $user->name }} came to work on {{ $attendance->id }}</li>     <!--$user->name, $attendance->id - You can always get any other user/attendance attribute you want-->
    @endforeach
</li>
