我的NotesController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;


}
}

卡片型号如下

 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;
   }
}

Answer 1

根据Laravel from scratch tutorial您要将记事保存到卡片中。因此，您应该使用$card->notes()->sav‌e($note);代替$note->notes()->save($note);
