Symfony 3.4：关于将对象数组集合保存到OneToMany的问题

我需要你们帮助解决我在表中保存数据的问题。 我使用fosUserBundle，有不同的用户类型Admin、Pro和Client，它们是扩展基本用户实体的类。 我还有一个语言实体，它通过一对多关联链接到用户。 要订阅，用户客户端需要通过复选框检查他所说的语言

表单页面正常，它显示UserClient表单+父用户表单，并将语言列表作为复选框

问题在于表中保存的数据。 我在“语言”列中有相同的值：

这是我的密码：

User.php

我需要将语言作为userClient的数组存储在数据库中。

你能帮我吗。

谢谢你重新编辑我的问题Philip-B- 谢谢你的阅读

我已通过添加foreach将对象转换为数组来解决问题： 代码在我的控制器中：

if ($form->isValid()) {
                $event = new FormEvent($form, $request);
                $dispatcher->dispatch(FOSUserEvents::REGISTRATION_SUCCESS, $event);

                foreach ($user->getLanguages() as $value) {
                    $langue[] = $value->getShortSlug();
                }
                $user->setLanguages($langue);
                $userManager->updateUser($user);

                if (null === $response = $event->getResponse()) {
                    $url = $this->generateUrl('fos_user_registration_confirmed');
                    $response = new RedirectResponse($url);
                }

                $dispatcher->dispatch(FOSUserEvents::REGISTRATION_COMPLETED, new FilterUserResponseEvent($user, $request, $response));
