Question

如何查询具有ID并且路线中还有slug的特定帖子？这是为了更新特定的帖子。我已经尝试将slug添加到更新路径中无济于事（未找到异常触发器），找到具有id和slug值的帖子的正确方法是什么？

路线：

显示

 BloggerBlogBundle_blog_show:
    path:  /{id}/{slug}
    defaults: { _controller: BloggerBlogBundle:Blog:show }
    requirements:
        methods:  GET
        id: \d+

更新

BloggerBlogBundle_blog_update:
path:  /{id}/{slug}/update
defaults: { _controller: BloggerBlogBundle:Blog:update, id: $id }
requirements:
    id: \d+

控制器：

BlogController（更新动作）

  public function updateAction($id, Request $request)
{
    $em = $this->getDoctrine()
        ->getManager();

    $blog = $em->getRepository('BloggerBlogBundle:Blog')
        ->find($id);

    if (!$blog) {
        throw $this->createNotFoundException(
            'No blog was found for this id' . $id
        );
    }

    $form = $this->createFormBuilder($blog)
        ->add('title', 'text')
        ->add('author', 'text')
        ->add('blog', 'text')
        ->add('image', 'text')
        ->add('tags', 'text')
        ->add('save', 'submit')
        ->getForm();

    $form->handleRequest($request);

    if ($form->isValid()) {
        $em->flush();

        // return new Response('Blog was updated successfully');
        return $this->redirect($this->generateUrl('BloggerBlogBundle_homepage'));
    }

    $build['form'] = $form->createView();

    return $this->render('BloggerBlogBundle:Blog:create.html.twig', $build);
}

好的，弄清楚我做错了什么。需要将$ slug传递给updateAction参数并使用每个nifr的findOneBy（数组）（感谢您的帮助）。

更新路线：

BloggerBlogBundle_blog_update:
path:  /{id}/{slug}/update
defaults: { _controller: BloggerBlogBundle:Blog:update }
requirements:
    id: \d+

更新了控制器：

public function updateAction($id, $slug, Request $request)
{
    $em = $this->getDoctrine()
        ->getManager();

    $blog = $em->getRepository('BloggerBlogBundle:Blog')
        ->findOneBy(array(
            'id'   => $id,
            'slug' => $slug
        ));

    if (!$blog) {
        throw $this->createNotFoundException(
            'No blog was found for this id/slug: ' . $id. $slug
        );
    }

    $form = $this->createFormBuilder($blog)
        ->add('title', 'text')
        ->add('author', 'text')
        ->add('blog', 'text')
        ->add('image', 'text')
        ->add('tags', 'text')
        ->add('save', 'submit')
        ->getForm();

    $form->handleRequest($request);

    if ($form->isValid()) {
        $em->flush();

        // return new Response('Blog was updated successfully');
        return $this->redirect($this->generateUrl('BloggerBlogBundle_homepage'));
    }

    $build['form'] = $form->createView();

    return $this->render('BloggerBlogBundle:Blog:create.html.twig', $build);
}

您可以使用doctrine的id方法同时查询与slug和findOneBy(array $criteria)匹配的条目。

$request    = $this->getRequest()->request;
$em         = $this->getDoctrine()->getManager();
$repository = $em->getRepository('AcmeYourBundle:Entity'):

$entity = $repository->findOneBy(array(
    'id'   => $request->get('id'),
    'slug' => $request->get('slug'),
));
