Php Doctrine2 ORM-由FK删除而不从DB检索

我有两个实体-UserAccounts（

user\u accounts

table，以

id

为主键）和blacklisteduser（

blacklistedu用户

，以

id

为主键，以

user\u accounts.id

为FK引用

user\u accounts.id

）。这里的挑战是通过

user\u accounts\u id

列而不是通常的PK

id

删除黑名单用户条目。重要的是，我不想从DB加载实体来删除它。我也不愿意将DQL用于这样一个简单的查询

我已经尝试了一段时间，不断地出现不同的错误

$blacklist_ref = EntityManagerContainer::get()->getPartialReference(BlacklistedUsers::class, array("user_account_id" => $user_id));
EntityManagerContainer::get()->remove($blacklist_ref);
EntityManagerContainer::get()->flush();

{“错误”：[“未定义索引：用户帐户id”]}

{“错误”：[“未定义索引：用户帐户”]}

{“错误”：[“DoctrineProxies类的对象\\uuuuucg\uuuuuorm\Entity\UserAccounts无法转换为字符串”]}

{“errors”：[“Orm\Entity\BlacklistedUsers的查询缺少标识符id]}

条令可以通过EntityManager做这么简单的事情吗

"delete from blacklisted_users where user_account_id = {$id}"

  $user_ref = EntityManagerContainer::get()->getReference(UserAccounts::class, $user_id);
  $blacklist_ref = EntityManagerContainer::get()->getPartialReference(BlacklistedUsers::class, array("user_account" => $user_ref));
  EntityManagerContainer::get()->remove($blacklist_ref);
  EntityManagerContainer::get()->flush();

$user_ref = EntityManagerContainer::get()->getReference(UserAccounts::class, $user_id);
$blacklist_ref = EntityManagerContainer::get()->getReference(BlacklistedUsers::class, array("user_account" => $user_ref));
EntityManagerContainer::get()->remove($blacklist_ref);
EntityManagerContainer::get()->flush();

"delete from blacklisted_users where user_account_id = {$id}"
