Symfony2 - 方法名称必须以 findBy 或 findOneBy 开头

Question

首先让我说，我知道这个问题之前已经出现过，但似乎没有一个解决方案有效。而且，我不是新会员，我只是不记得我的登录详细信息，所以我不得不重新注册....

基本上，我的工作是重新整理一个现有的 Symfony2 项目，该项目从未完成，也没有很好地组合在一起。但是，由于某种奇怪的原因，当我尝试在名为 Customer 的存储库中调用方法“count”时突然出现上述错误。

这是 Repo 中的方法（请记住，我的目录不叫 Acme，只是为了简单起见在这里替换）：

public function count($type)
{
    return $this->getEntityManager()
        ->createQuery('SELECT COUNT(c) FROM AcmePagesBundle:customer c WHERE c.status = :type')
        ->setParameter('type', $type)
        ->getSingleScalarResult();
}

它是从主树枝模板中调用的，如下所示：

{{ render(controller('AcmeCustomerBundle:Customer:count', {'type':'private'})) }}

我在运行应用程序时收到的错误是：

在渲染模板期间引发了异常 ("未定义的方法'count'。方法名称必须以任何一个开头 findBy 或 findOneBy!") 在 AcmePagesBundle::main.html.twig 在第 30 行。

我正在使用我认为是 2.7 的最新版本的 Symfony。我确定它以前可以工作，但是在清除缓存并重新生成实体之后，它似乎把事情搞砸了。我已经尝试了大多数其他建议，但现在不知所措。

如果有人能对此有所了解，我将不胜感激，谢谢。

仔细检查您的实体定义：Doctrine 似乎使用的是默认存储库而不是您的自定义存储库。

您必须在@ORM\Entity 注解内设置repositoryClass 选项：

/**
 * @ORM\Entity(repositoryClass="AppBundle\Entity\Repository\GroupRepository")
 * [...]
 */
class Group
{
    // [...]
}
