ProiodaController.php第32行中的Laravel CRUD生成器FatalThrowableError：调用未定义的方法App \ DataTables \ ProiodaDataTable :: render（）

Question

我正在开发一个Laravel 5.4项目并且我已经下载了crud generator包，但是当我使用--datatables=true标记并且我转到视图时，我收到错误：< / p>

FatalThrowableError in ProiodaController.php line 32:
Call to undefined method App\DataTables\ProiodaDataTable::render()

我正在使用yajra/laravel-datatables这样的生成器来工作需要它。

Generator已生成所有视图文件控制器请求模型存储库，并在名为DataTables的文件夹中生成名为ProiodaDataTable.php的文件。

以下是ProiodaController.php

<?php
    namespace App\Http\Controllers;
    use App\DataTables\ProiodaDataTable;
    use App\Http\Requests;
    use App\Http\Requests\CreateProiodaRequest;

    use App\Repositories\ProiodaRepository;
    use Flash;
    use App\Http\Controllers\AppBaseController;
    use Response;

class ProiodaController extends AppBaseController
{
    /** @var  ProiodaRepository */
    private $proiodaRepository;

    public function __construct(ProiodaRepository $proiodaRepo)
    {
        $this->proiodaRepository = $proiodaRepo;
    }

    /**
    * Display a listing of the Proioda.
    *
    * @param ProiodaDataTable $proiodaDataTable
    * @return Response
    */
    public function index(ProiodaDataTable $proiodaDataTable)
    {
        return $proiodaDataTable->render('proiodas.index');
    }

    /**
    * Show the form for creating a new Proioda.
    *
    * @return Response
    */
    public function create()
    {
        return view('proiodas.create');
    }

/**
 * Store a newly created Proioda in storage.
 *
 * @param CreateProiodaRequest $request

public function store(CreateProiodaRequest $request)
{
    $input = $request->all();

    $proioda = $this->proiodaRepository->create($input);

    Flash::success('Proioda saved successfully.');

    return redirect(route('proiodas.index'));
}

/**

 *
 * @param  int $id
 *
 * @return Response
 */
public function show($id)
{
    $proioda = $this->proiodaRepository->findWithoutFail($id);

    if (empty($proioda)) {
        Flash::error('Proioda not found');

        return redirect(route('proiodas.index'));
    }

    return view('proiodas.show')->with('proioda', $proioda);
}

/**
 * Show the form for editing the specified Proioda.

    if (empty($proioda)) {
        Flash::error('Proioda not found');

        return redirect(route('proiodas.index'));
    }

    return view('proiodas.edit')->with('proioda', $proioda);
}

/**

 *
 * @param  int              $id
 * @param UpdateProiodaRequest $request
 *

 */
public function update($id, UpdateProiodaRequest $request)
{
    $proioda = $this->proiodaRepository->findWithoutFail($id);

    if (empty($proioda)) {
        Flash::error('Proioda not found');

        return redirect(route('proiodas.index'));
    }

    $proioda = $this->proiodaRepository->update($request->all(), $id);

    Flash::success('Proioda updated successfully.');

    return redirect(route('proiodas.index'));
}

/**
 * Remove the specified Proioda from storage.
 *
 * @param  int $id
 *
 * @return Response
 */
public function destroy($id)
{
    $proioda = $this->proiodaRepository->findWithoutFail($id);

    if (empty($proioda)) {
        Flash::error('Proioda not found');

        return redirect(route('proiodas.index'));
    }

    $this->proiodaRepository->delete($id);

    Flash::success('Proioda deleted successfully.');

    return redirect(route('proiodas.index'));
}

}

这是ProiodaDataTable.php

    <?php
