我目前正在使用Symfony2' Part 4 OF The SymBlog project 我收到此错误消息:
Undefined method 'getLatestPosts'. The method name must start with either findBy
or findOneBy!500 Internal Server Error - BadMethodCallException
这是我的PostRepository类:
<?php
namespace BLog\BlogBundle\Entity; use Doctrine\ORM\EntityRepository;
class PostRepository extends EntityRepository {
public function getLatestPosts($limit = null) {
$qp = $this->createQueryBuilder('p')
->select('p')
->addOrderBy('p.created', 'DESC');
if (false === is_null($limit)) {
$qp->setMaxResults($limit);
}
return $qp->getQuery()
->getResult();
}
}
这是Controller的页面Action方法:
<?php
namespace Blog\BlogBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class DefaultController extends Controller {
public function indexAction() {
$em = $this->getDoctrine()
->getEntityManager();
$posts = $em->getRepository('BlogBundle:Post')
->getLatestPosts();
return $this->render('BlogBundle:Default:home.html.twig', > >array(
'posts' => $posts
));
}
...
}
这是我的../../../Entity/Post代码的示例:
<?php
namespace Blog\BlogBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* @ORM\Entity(repositoryClass="Blog\BlogBundle\Entity\PostRepository")
* @ORM\Table(name="post")
* @ORM\HasLifecycleCallbacks
*/
class Post {
....
...
..
/**
* @ORM\Column(type="text")
*/
protected $post;
...
...
我还通过post
尝试了此ScoRpion中的所有解决方案这里的问题是什么?
答案 0 :(得分:0)
此处无需使用存储库。如果您通过引用实体直接获取数据,那么您应该使用数据库字段名称发布的findBy或findOneBy。 请尝试以下方式:
namespace Blog\BlogBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class DefaultController extends Controller {
public function indexAction() {
$posts = this->forward('BlogBundle:Post:getLatestPosts', array(), array());
return $this->render('BlogBundle:Default:home.html.twig', > >array(
'posts' => $posts
));
}
...
}
