php - Laravel 路由模型绑定(bind) : destroy method not grab necessary info

Question

这是我的 ProducerType 模型 Controller :

namespace App\Http\Controllers;

use App\ProducerType;
use App\Http\Requests\ValidateProducerTypes;
use Illuminate\Http\Request;

class ProducerTypeController extends Controller
{
    public function __construct()
    {
        $this->middleware('auth');
    }

    ...

    public function destroy(ProducerType $producerType)
    {
        $producerType->delete();
        return redirect('/producers');
    }
}

这是我的模型:

namespace App;

use Illuminate\Database\Eloquent\Model;

class ProducerType extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'nome'
    ];
}

看法:

<form action="/producers-type/{{ $type->id }}" method="POST">
    @csrf
    @method('DELETE')
    <button type="submit" class="btn-icon">
        <img src="{{ asset('images/times-circle-regular.svg') }}" alt="">
    </button>
</form>

路线:

Route::resource('producers-type', 'ProducerTypeController', [
    'only' => ['store', 'update', 'destroy']
])->middleware('permission:create users');

我的问题是: $producerType变量没有捕获必要的属性。

Answer 1

虽然上面的答案给出了问题的解决方案，但我最终在我的代码中发现了问题!

来自 Route Model Binding 的 Laravel 文档:

Since the $user variable is type-hinted as the App\User Eloquent model and the variable name matches the {user} URI segment, Laravel will automatically inject the model instance that has an ID matching the corresponding value from the request URI. If a matching model instance is not found in the database, a 404 HTTP response will automatically be generated.

这是我的问题:我正在使用 $producerType变量和 Laravel 期待 $producers_type因为我的路线 producers-type/{producers_type} .
