Question

当我将FPNTagBundle用于系统标记时，我遇到了这个问题：

当我刷新网页时，这个问题显而易见

使用params执行'INSERT INTO标记（name，slug，created_at，updated_at）VALUES（？，？，？，？）'时发生异常[null，“”，“2017-06-28 17:41： 34“，”2017-06-28 17:41:34“]：

SQLSTATE [23000]：完整性约束违规：1048列“名称”不能为空 500内部服务器错误 - NotNullConstraintViolationException 2个链接的异常：PDOException»PDOException»

代码控制器：

  public function createTagsAction()
{
    // create your entity
     $post = new Post();
    $post->setTitle('salah');

    $tagManager = $this->get('fpn_tag.tag_manager');
        $f = $this->container->get('request')->request->get('data');

    // ask the tag manager to create a Tag object
    $fooTag = $tagManager->loadOrCreateTag($f);

    // assign the foo tag to the post
    $tagManager->addTag($fooTag, $post);

    $em = $this->getDoctrine()->getEntityManager();

    // persist and flush the new post
    $em->persist($post);
    $em->flush();

    // after flushing the post, tell the tag manager to actually save the tags
    $tagManager->saveTagging($post);

    // ...

    // Load tagging ...
    $tagManager->loadTagging($post);

    $m = "success";

    return $this->render('MedBundle:Default:tag.html.twig',array('m' => $m));
}
