php - Laravel - 可重用的资源控制器

Question

我正在修改我在项目中使用的 CMS，最近我决定为默认操作创建一个控制器BaseController，所有其他控制器都将扩展这个控制器BaseController。

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;

class BaseController extends Controller
{
    protected $viewFolder = 'admin';

    protected $title;

    protected $model;

    protected $key = 'id';

    protected $files = [];

    public function __construct()
    {
        $this->setVariable('title', $this->title);
    }

    public function index()
    {
        $items = $this->model::paginate();

        $this->setVariable('items', $items);

        return $this->viewRender('index');
    }

    public function create()
    {
        return $this->viewRender('create');
    }

    public function store(ExampleStoreRequestFROMEXAMPLECONTROLLER $request)
    {
        $item = $this->model::create($request->all());

        return redirect()->route($this->viewFolder.'.'.$this->viewType.'.show', $item[$this->key]);
    }

    public function show($id)
    {
        $item = $this->model::where($this->key, $id)->firstOrFail();

        $this->setVariable('item', $item);

        return $this->viewRender('show');
    }

    public function edit($id)
    {
        $item = $this->model::where($this->key, $id)->firstOrFail();

        $this->setVariable('item', $item);

        return $this->viewRender('edit');
    }

    public function update(ExampleUpdateRequestFROMEXAMPLECONTROLLER $request, $id)
    {
        $item = $this->model::where($this->key, $id)->firstOrFail();

        $item->update($request->except(['_token', '_method']));

        return redirect()->route($this->viewFolder.'.'.$this->viewType.'.show', $item[$this->key]);
    }

    public function status(ExampleStatusRequestFROMEXAMPLECONTROLLER $request, $id)
    {
        $this->model::where($this->key, $id)->update($request->except('_method'));

        return response()->json([
            'message' => 'O status foi alterado com sucesso'
        ]);
    }

    public function destroy($id)
    {
        $this->model::where($this->key, $id)->delete();

        return redirect()->route($this->viewFolder.'.'.$this->viewType.'.index');
    }
}

BaseController问题是：我使用表单请求编写了UserController，我不知道如何让这些请求保持动态，以便我可以从其他控制器实现它们。

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Requests\ExampleStatusRequest;
use App\Http\Requests\ExampleStoreRequest;
use App\Http\Requests\ExampleUpdateRequest;

class ExampleController extends BaseController
{
    protected $viewType = 'users';

    protected $model = 'App\Example';

    public function index()
    {
        $this->setVariable('title', 'Usuários');
        return parent::index();
    }

    public function create()
    {
        $this->setVariable('title', 'Cadastrar usuário');
        return parent::create();
    }

    public function store(ExampleStoreRequest $request)
    {
        return parent::store($request);
    }

    public function edit($id)
    {
        $this->setVariable('title', 'Editar usuário');
        return parent::edit($id);
    }

    public function update(ExampleUpdateRequest $request, $id)
    {
        return parent::update($request, $id);
    }

    public function status(ExampleStatusRequest $request, $id)
    {
        return parent::status($request, $id);
    }
}

这是我的默认控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    protected $viewFolder = '';

    protected $viewType = '';

    protected $viewVariables = [];

    protected function setVariable($key, $value)
    {
        $this->viewVariables[$key] = $value;
    }

    protected function viewRender($view)
    {
        return view($this->viewFolder.'.pages.'.$this->viewType.'.'.$view, $this->viewVariables);
    }
}

知道如何解决这个问题吗？

评论后我可以更好地理解。我在这里遇到了同样的问题，这是我的解决方法

class BaseController extends Controller
{

     protected function _store($request)
     {
     ....
     }
 ...
 }

 class MyController extends BaseController
 {
 ....
      public function store(MyRequest $request)
      {
          //do something
          return parent::_store($request);
      }
 }
