学说中的实体存储库

Question

I am having issues running through the doctrine tutorial and attempting to setup entity repos.

// _src/entities/User.php
/**
 * @ORM\Entity(repositoryClass="UserRepository")
 * @Entity @Table(name="users")
 */
class User
{
    /**
 * @Id @GeneratedValue @Column(type="integer")
 * @var int
 */
protected $id;
/** @Column(type="string") */
protected $fname;
/** @Column(type="string") */
protected $lname;

public function getId()
{
    return $this->id;
}

public function getFname()
{
    return $this->fname;
}

public function setFname($fname)
{
    $this->fname = $fname;
}
public function getLname()
{
    return $this->lname;
}

public function setLname($lname)
{
    $this->lname = $lname;
}
}

I am then calling:

$users = $em->getRepository('User')->getUsersByLastName('user');
var_dump($users);

My Repo:

// _src/entities/UserRepository.php

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
    public function getUsersByLastName($lname)
    {
        $dql = "SELECT u FROM User u WHERE u.lname = ?1 ORDER BY b.created DESC";

        return $this->getEntityManager()->createQuery($dql)
        ->setParameter(1, $lname)
        ->getResult();
    }
}

I am following the tutorial and don't understand what I am missing. Any assistance would be amazing. I am trying to learn this rather quickly and can't believe im running into these issues already.

Here is the error I am getting:

PHP Fatal error: Uncaught BadMethodCallException: Undefined method 'getUsersByLastName'. The method name must start with either findBy or findOneBy! in /Users/ks/Documents/PHPStormProjects/dan/_vendor/doctrine/orm/lib/Doctrine/ORM/EntityRepository.php:226

Stack trace:

#0 /Users/ks/Documents/PHPStormProjects/dan/test.php(27): Doctrine\ORM\EntityRepository->__call('getUsersByLastN...', Array)

#1 {main} thrown in /Users/ks/Documents/PHPStormProjects/dan/_vendor/doctrine/orm/lib/Doctrine/ORM/EntityRepository.php on line 226

Answer 1

I found the answer. It was literally in the error. Once I changed the method to public function findByLname($lname) it worked. I need to review the documentation more carefully. Seems weird, you can't name methods whatever you want.

I still am unsure on the clear cache error. Followed that documentation correctly I thought too.
