发布者Laravel 5.8时的空桌子

Question

我的某些观点是空的。有关各方是必须提供外键信息的各方。

我使用Laravel 5.8开发了一个应用程序，并且我有一个控制器可以检测不同的香水线，一个产品控制器和一个香水控制器。我将“产品”表的标识符迁移到“香水”表中。当我想在视图级别显示有关香水表的信息时，出现此错误：

尝试获取无对象的属性“名称”（显示：C：\ laragon \ www \ venome \ resources \ views \ admin \ fragrance \ index.blade.php）。

所以我更改了代码，但是现在部分视图为空。

路线

Route::group(['prefix' => 'admin', 'middleware' => 'auth', 'namespace' => 'admin'], function () {
    Route::get('dashboard', 'DashboardController@index')->name('admin.dashboard');
    Route::resource('ligne', 'LigneController');
    Route::resource('produit', 'ProduitController');
    Route::resource('fragrance', 'FragranceController');
});

控制器

namespace App\Http\Controllers\Admin;

use App\Fragrance;
use App\Http\Controllers\Controller;
use App\Ligne;
use App\Produit;

class FragranceController extends Controller
{
    public function index()
    {
        $fragrances = Fragrance::all();
        $lignes = Ligne::all();
        $produits = Produit::all();

        return view('admin.fragrance.index', compact('fragrances', 'lignes', 'produits'));
    }
}

模型

class Fragrance extends Model
{
    public function lignes()
    {
        return $this->belongsTo(Ligne::class);
    }

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

class Ligne extends Model
{
    public function fragrances()
    {
        return $this->hasMany(Fragrance::class);
    }
}


class Produit extends Model
{
    public function fragrance()
    {
        return $this->hasMany(Fragrance::class);
    }
}
