如何在Symfony3.4中使用Lock Component和username

Question

我试图在symfony 3.4中使用锁组件，就像在https://symfony.com/doc/3.4/components/lock.html上描述的那样

我想阻止来自不同用户的多个数据更改。

例如，user1使用数据调用相同的公司表单，然后是user2

如何告诉user2，user1阻止了编辑数据（包括用户名）？

更新：它用于后端，许多员工编辑客户数据，订单等。此表单仅供编辑。这意味着，如果他们想要更新某些数据，他们会点击“编辑”。在将数据加载到表单之前，当另一名员工更改此记录时，应通知他们。员工有时需要一些时间来改变一切。如果员工在保存时收到消息，则必须返回，重新加载数据并重新开始。

我的控制器的一个例子：

 public function CompanyEdit(Request $request)
    

        $error = null;
        $company_id                                 = $request->get('id');
//        if (!preg_match('/^\d+$/', $company_id))
//            return $this->showError();
//        

        $store = new SemaphoreStore();
        $factory = new Factory($store);
        $lock = $factory->createLock('company-edit-'.$company_id, 30);

        if(!$lock->acquire()) 
             //send output with username
            // this data is locked by user xy
            return 0;
        

        $company = $this->getDoctrine()->getRepository(Company::class)->find($company_id);
        $payment = $this->getDoctrine()->getRepository(Companypay::class)->findOneBy(array('company_id' => $company_id));

        $form = $this->createFormBuilder()
            ->add('company', CompanyFormType::class, array(
                'data_class' => 'AppBundle\Entity\Company',
                'data' => $company
            ))
            ->add('payment', CompanyPayFormType::class, array(
                'data_class' => 'AppBundle\Entity\CompanyPay',
                'data' => $payment

            ))
            ->getForm();

        $form->handleRequest($request);
        $company = $form->get('company')->getData();
        $payment = $form->get('payment')->getData();

        if ($form->isSubmitted() && $form->isValid()) 
            $event = new FormEvent($form, $request);

            if ($payment->getCompanyId() == null) 
                $payment->setCompanyId($company->getId());
            

            try 
                $this->getDoctrine()->getManager()->persist($company);
                $this->getDoctrine()->getManager()->persist($payment);
                $this->getDoctrine()->getManager()->flush();
                $this->container->get('app.logging')->write('Kundendaten geändert', $company->getId());
             catch (PDOException $e) 
                $error = $e->getMessage();
            
            if (null === $response = $event->getResponse()) 

                return $this->render('customer/edit.html.twig', [
                    'form' => $form->createView(),
                    'company' => $company,
                    'error' => $error,
                    'success' => true
                ]);
            
            $lock->release();
            return $response;
