问题
I am currently working with Symfony2's Part 4 OF The SymBlog project I am getting this ERROR message:
Undefined method 'getLatestPosts'. The method name must start with either findBy
or findOneBy!500 Internal Server Error - BadMethodCallException
This is my PostRepository Class:
<?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();
}
}
This is the Controller's page Action method:
<?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
));
}
...
}
This is a sample of my ../../../Entity/Post code:
<?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;
...
...
I also tried all solutions in this post by ScoRpion
What is THE PROBLEM here ???
回答1:
No need to use repository here. If you are fetching data directly by refering entity then you should use findBy or findOneBy posted by your database field name. Please Try to do following way:
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
));
}
...
}
