在Builder.php中的BadMethodCallException行2345：调用未定义的方法Illuminate \ Database \ Query \ Builder :: notes（）

Question

我从laracats.com从零开始学习laravel时遇到了上述错误， bellow是完全错误消息

哎呀，看起来像是出了点问题。 1/1 BadMethodCallException在Builder.php线2345：调用未定义的方法照亮\数据库\查询\生成器：注释（）

我NotesController是如下

namespace App\Http\Controllers; 

use App\Card; 
use App\Note; 
use Illuminate\Http\Request; 


class NotesController extends Controller 
{ 
    public function store(Request $request, Card $card) 
    { 


     $note = new Note; 

     $note->body = $request->body; 
     $note->notes()->save($note); 

     return back; 


} 
} 

卡模型如下

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Card extends Model 
{ 
    public function notes() 
    { 
    return $this->hasMany(Note::class); 
    } 

    public function path() 
    { 
    return '/cards/'.$this->id; 
    } 
}

按照Laravel from scratch tutorial您要注意保存到存储卡。所以你应该使用$card->notes()->sav‌​e($note);而不是$note->notes()->save($note);
