如何提高entity_revision的路由参数？

Question

我的定制实体是可修正的。我可以看到修订，但我的修订还原表单不起作用。表单的路由在msul_rovi_games.routing.yml中定义。

entity.rovi_game.revision_revert_confirm:
  path: '/rovi_game/{rovi_game}/revisions/{rovi_game_revision}/revert'
  defaults:
    _title: 'Revert to an earlier revision'
    _form: '\Drupal\msul_rovi_games\Form\RoviGameRevisionRevertForm'
  requirements:
    _permission: 'administer rovi_game entities'
    rovi_game: \d+
  options:
    _node_operation_route: TRUE
    rovi_game:
      type: entity:rovi_game
    rovi_game_revision:
      type: entity_revision:rovi_game

表单在src/ form /RoviGameRevisionRevertForm.php中定义。

namespace Drupal\msul_rovi_games\Form;

use Drupal\Component\Datetime\TimeInterface;
use Drupal\Core\Datetime\DateFormatterInterface;
use Drupal\Core\Entity\EntityRepositoryInterface;
use Drupal\Core\Entity\Sql\SqlContentEntityStorage;
use Drupal\Core\Entity\EntityStorageInterface;
use Drupal\Core\Form\ConfirmFormBase;
use Drupal\Core\Form\FormStateInterface;
use Drupal\Core\Url;
use Drupal\msul_rovi_games\Entity\RoviGameInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;

/**
 * Provides a form for reverting a rovi_game revision.
 *
 * @internal
 */
class RoviGameRevisionRevertForm extends ConfirmFormBase {

  /**
   * {@inheritdoc}
   */
  public function buildForm(array $form, FormStateInterface $form_state, RoviGameInterface $rovi_game_revision = NULL) {
    $this->revision = $rovi_game_revision;
    $form = parent::buildForm($form, $form_state);

    return $form;
  }
}

当我试图恢复时，我会得到以下错误。

传递给Drupal\msul_rovi_games\Form\RoviGameRevisionRevertForm::buildForm()的参数3必须实现接口Drupal\msul_rovi_games\Entity\RoviGameInterface或null，在Drupal\msul_rovi_games\Form\RoviGameRevisionRevertForm->buildForm()中给出字符串( /opt/drupal/web/modules/custom/msul_rovi_games/src/Form/RoviGameRevisionRevertForm.php)的第116行)

我遗漏了什么？

您只是在选项数组中缺少了一个级别，“参数”。见上行路由段塞名称选项。注意，参数必须嵌套在选项>参数下。

foobar.view:
  path: '/foobar/{foobar_placeholder}'
  defaults:
    _controller: '\Drupal\foobar\Controller\Foobar::content'
    _title: 'Oh yeah foobar'
  options:
    parameters:
      foobar_placeholder:
        type: entity:foobar

您的代码已更新：

entity.rovi_game.revision_revert_confirm:
  path: '/rovi_game/{rovi_game}/revisions/{rovi_game_revision}/revert'
  defaults:
    _title: 'Revert to an earlier revision'
    _form: '\Drupal\msul_rovi_games\Form\RoviGameRevisionRevertForm'
  requirements:
    _permission: 'administer rovi_game entities'
    rovi_game: \d+
  options:
    _node_operation_route: TRUE
    # Nest parameters under "parameters"
    parameters:
      rovi_game:
        type: entity:rovi_game
      rovi_game_revision:
        type: entity_revision:rovi_game
