首先让我说，我知道之前出现了这个问题，但没有一个解决方案似乎有效。而且，我也不是新成员，我记不起我的登录信息，所以我不得不重新注册....
基本上，我的工作是重新整理现有的Symfony2项目，该项目从未完成，并没有很好地整合在一起。但是，由于某些奇怪的原因，我在尝试在名为Customer的存储库中调用方法“count”时突然遇到上述错误。
这是Repo中的方法（请记住，我的目录不称为Acme，为简单起见，它仅在此处替换）：
public function count($type)
{
return $this->getEntityManager()
->createQuery('SELECT COUNT(c) FROM AcmePagesBundle:customer c WHERE c.status = :type')
->setParameter('type', $type)
->getSingleScalarResult();
}
它是从主枝模板调用的，如下所示：
{{ render(controller('AcmeCustomerBundle:Customer:count', {'type':'private'})) }}
运行应用程序时收到的错误是：
在第30行的AcmePagesBundle :: main.html.twig中，在呈现模板期间抛出了异常（“未定义的方法'count'。方法名称必须以findBy或findOneBy！”开头。）。
我正在使用Symfony的最新版本，我认为它是2.7。我确定它之前有效，但在清除缓存并重新生成实体之后，它似乎已经搞砸了。我已经尝试了大多数其他建议，但现在我不知所措。
如果有人能对此有所了解，我会非常感激，谢谢。

仔细检查您的实体定义：似乎Doctrine正在使用默认存储库而不是您的自定义存储库。
你必须在repositoryClass注释中设置@ORM\Entity选项：
/**
* @ORM\Entity(repositoryClass="AppBundle\Entity\Repository\GroupRepository")
* [...]
*/
class Group
{
// [...]
}
