Forms Symfony2检查表单行的值

我需要向表中添加一些数据。主要思想是每个工人都有自己的身份证。这是每个工人自己设定的。它们都是弦

表中的结构：

名字

姓

电话号码

识别通行证

我的问题是：

我需要：

检查IDENTPASS的值是否为UNIQE 但每次我都想编辑这个表单，但改变了不同的行。我得到一个错误，因为他说IDENTPASS的值存在。因为他想再次保存，并且已经有了这个值

现在我有很多“如果”，这是我的坏主意。并不是所有的工作

我的控制器：

好的，我不知道我是否涵盖了所有内容，但我想这可以开始了。请注意，我们使用相同的表格进行insert nad更新。这决不是完全完成的代码，您可以即插即用，而是触及您可以做的表面

public function insertEditAction($id){
    $employeeRepo = $this->getDoctrine()->getRepository('MainCoreBundle:Employee');

    if (!is_null($id)){
        $employee=$employeeRepo->find($id); // For update
    }else{
        $employee = new Employee(); // For insert
    }

    $employeeForm = $this->createForm(new EmployeeType(), $employee);

    if ( $request->getMethod() === "POST"){
        $form->bind($request);

        if ( $form->isValid()){
            $em = $this->getDoctrine()->getManager();
            $existingByIdentPass = $employeeRepo->findOneByIdentpass($employee->getIdentpass());

            // If there is some other employee with this IDENT_PASS then redirect back to form
            if($existingByIdentPass !== NULL && $existingByIdentPass->getId() !== $employee->getId()){
                return $this->redirect($this->generateUrl('employee_edit', array('id' => $id)));
            }

            // New employee, set the SPOT and PERSIST
            // calling persist is only required when creating new record
            if ( $employee->getId() === NULL ){
                $employee->setSpot($spot);
                $em->persist($employee);
            }

            // Flush the changes
            $em->flush();

            return $this->redirect($this->generateUrl('employee_index'));
        }
    }

    return $this->render('MainBundle:Employee:entity.html.twig', $this->getViewConstants(array('form' => $employeeForm->createView(), 'pass'=>$passFromBase)));
}

好的，这里有几件事你可以改进。。。现在写答案。。。

public function insertEditAction($id){
    $employeeRepo = $this->getDoctrine()->getRepository('MainCoreBundle:Employee');

    if (!is_null($id)){
        $employee=$employeeRepo->find($id); // For update
    }else{
        $employee = new Employee(); // For insert
    }

    $employeeForm = $this->createForm(new EmployeeType(), $employee);

    if ( $request->getMethod() === "POST"){
        $form->bind($request);

        if ( $form->isValid()){
            $em = $this->getDoctrine()->getManager();
            $existingByIdentPass = $employeeRepo->findOneByIdentpass($employee->getIdentpass());

            // If there is some other employee with this IDENT_PASS then redirect back to form
            if($existingByIdentPass !== NULL && $existingByIdentPass->getId() !== $employee->getId()){
                return $this->redirect($this->generateUrl('employee_edit', array('id' => $id)));
            }

            // New employee, set the SPOT and PERSIST
            // calling persist is only required when creating new record
            if ( $employee->getId() === NULL ){
                $employee->setSpot($spot);
                $em->persist($employee);
            }

            // Flush the changes
            $em->flush();

            return $this->redirect($this->generateUrl('employee_index'));
        }
    }

    return $this->render('MainBundle:Employee:entity.html.twig', $this->getViewConstants(array('form' => $employeeForm->createView(), 'pass'=>$passFromBase)));
}
