此集合实例上不存在属性[stats]

Question

I am new in laravel and I got this error

Property [stats] does not exist on this collection instance. (View: C:\\xampp\\htdocs\\enginepoker2\\resources\\views\\pages\\players.blade.php)

this is in players.blade.php

@foreach ($player_stats->stats as $player_stat)

                        <tr class="gradeX">
                        <td><a href="">{{ $player_stat->username }}</a></td>
                        <td>{{ $player_stat->country }}</td>
                        <td>{{ $player_stat->rank }}</td>
                        <td class="center"><a href="#" class="name" data-name="winpot" data-pk="{{ $player_stat->ID }}" data-type="text" data-url="{{ route('updatePlayer') }}">{{ number_format($player_stat->winpot, 2, ',', '.') }}</a></td>
                        <td class="center"><a href="#" class="name" data-name="freeGames" data-pk="{{ $player_stat->ID }}" data-type="text" data-url="{{ route('updatePlayer') }}">{{ $player_stat->freeGames }}</a></td>
                            <td class="center"><a href="#" class="name" data-name="transferLimit" data-pk="{{ $player_stat->ID }}" data-type="text" data-url="{{ route('updatePlayer') }}">{{ number_format($player_stat->transferLimit, 2, ',', '.') }}</a></td>

                        </tr>

                        @endforeach

this is in controller

use App\players;
use Illuminate\Http\Request;

class playerController extends Controller
{

    public function index()
    {       
        $player_stats = players::where('bot', '=', '0')->orderBy('ID', 'DESC')->limit('500')->get();
        return view('pages.players', [ 'player_stats'=>$player_stats]);

    }
}

this is in players model

namespace App;

use Illuminate\Database\Eloquent\Model;

class players extends Model
{
    protected $player = 'players';

    public function stats()
    {
        return $this->belongsTo(stats::class);
    }

}

this is in stats model

namespace App;

use Illuminate\Database\Eloquent\Model;

class stats extends Model
{
    protected $player = 'stats';

    public function players()
    {
        return $this->hasMany(players::class);
    }    
}

Answer 1

First i think you should change first naming of your model with Capitalize name. I mean change class player to class Player and class stats to class Stats.

Second, use namespacing when try to add relation in laravel. Try change.

public function stats()
{
   return $this->belongsTo(stats::class);
}

to

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

also change the

public function players()
{
   return $this->hasMany(players::class);
}

to

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

Answer 2

stats is a relationship and relationships are not loaded by default; you should change your query in the controller to load the relationship. use this:

$player_stats = players::where('bot', '=', '0')->with('stats')
->orderBy('ID', 'DESC')->limit('500')->get();

EDIT: based on comments, you should tell laravel which columns to use for the relationship. and also the relationship was defined in reverse. try this:

change your relationships too:

class players extends Model
{
    protected $player = 'players';

    public function stats()
    {
        return $this->hasMany(stats::class, 'player', 'username');
    }
}

class stats extends Model
{
    protected $player = 'stats';

    public function players()
    {
        return $this->belongsTo(players::class, 'player', 'username');
    }     
}
