我怎样才能从mysql数据库中获取带有学说的数据表（Symfony 4）？

Question

像这样我的表是从数组填充数据：

  public function showAction(Request $request)
  {

    $table = $this->createDataTable()
    ->add('firstName', TextColumn::class)
    ->add('lastName', TextColumn::class)
    ->createAdapter(ArrayAdapter::class, [
      ['firstName' => 'Cat', 'lastName' => 'Duck'],
      ['firstName' => 'Monkey', 'lastName' => 'Dog'],
    ])
    ->handleRequest($request);

    if ($table->isCallback()) {
      return $table->getResponse();
    }

    return $this->render('list.html.twig', ['datatable' => $table]);
  }

但是我需要的是直接从mySQL数据库获取数据。 我用教义尝试了这个：

 public function showAction(Request $request)
  {
    $articles = $this->getDoctrine()->getRepository(Article::class)->findAll()->handleRequest($request);

    if ($articles ->isCallback()) {
      return $articles ->getResponse();
    }

    return $this->render('list.html.twig', ['datatable' => $articles]);
  }

但是我得到一个错误：

未捕获的PHP异常Symfony \\ Component \\ Debug \\ Exception \\ FatalThrowableError：/Users/work/project/src/Controller/DataTableController.php第27行上的“在数组上调用成员函数handleRequest（）”

我也试图这样写：

  public function showAction(Request $request)
  {
    $articles = $this->getDoctrine()->getRepository(Article::class)->findAll();

    return $this->render('list.html.twig', ['datatable' => $articles]);
  }

但是在这里我得到了错误：

传递给Omines \\ DataTablesBundle \\ Twig \\ DataTablesExtension :: Omines \\ DataTablesBundle \\ Twig {closure}（）的参数1必须是Omines \\ DataTablesBundle \\ DataTable的实例，给定的数组在/ Users / work / project / var / cache /中调用185行上的dev / twig / 0b / 0bf4881c934fbecf72f2dfcacd298733196c8daa0e22d77f67fcdf0fee9f33e4.php

根据文档（ https://omines.github.io/datatables-bundle/#doctrine-orm ）

在第一个示例中，您需要这样做：

public function showAction(Request $request)
{
    $table = $this->createDataTable()
    ->add('firstName', TextColumn::class)
    ->add('lastName', TextColumn::class)
    ->createAdapter(ORMAdapter::class, [
        'entity' => Article::class,
    ])
    ->handleRequest($request);

    if ($table->isCallback()) {
        return $table->getResponse();
    }

    return $this->render('list.html.twig', ['datatable' => $table]);
}

别忘了在课堂上添加以下内容：

use Omines\DataTablesBundle\Adapter\Doctrine\ORMAdapter;
