Question

我有一份员工登记表，如下所示，

namespace Hrm\EmployeeBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Hrm\UserBundle\Form\User\UserForm;

class EmpForm extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{   
    $builder->add('id','hidden');
    $builder->add('firs_name', 'text');
    $builder->add('middle_name', 'text');
    $builder->add('last_name', 'text');     
    $builder->add('user', new UserForm(), array('required' => false));
}

public function getName()
{
    return 'EmpForm';
}

}

我也有一个用户登录表单，如下所示

namespace Hrm\UserBundle\Form\User;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class UserForm extends AbstractType
{
  public function buildForm(FormBuilder $builder, array $options)
  {   
    $builder->add("id","hidden",array("required"=>false));
    $builder->add("userName","text",array("label"=>"Username"));
    $builder->add("password","password",array("label"=>"Password"));
    $builder->add("confirmPassword","password",array("property_path" => 
                   false,"label"=>"Confirm Password"));
    $builder->add("email","email",array("label"=>"Email"));
  }

  public function getName()
  {
    return 'user';
  }
}

员工YML文件如下，

Hrm\EmployeeBundle\Entity\Employee:
type: entity
table: employee
fields:
  id:
    type: integer
    id: true
    generator:
      strategy: AUTO
  firs_name:
    type: string
    length: '255'
    default: null
  middle_name:
    type: string
    length: '255'
    default: null
  last_name:
    type: string
    length: '255'
    default: null  
  oneToOne:
    User:
      targetEntity: Hrm\UserBundle\Entity\User
      cascade: ["remove", "persist"]
      joinColumn:
        name: login_id        
        referencedColumnName: id        
        nullable: true                   
 lifecycleCallbacks: {  }

员工控制器是这样的，

public function addEmployeeAction(Request $request) {

    $employee = new Employee();

    $user = new User();
    $employee->setUser($user);

    $form = $this->createForm(new EmpForm(), $employee);

    if ($request->getMethod() == 'POST') {

        $form->bindRequest($request);

        if ($form->isValid()) {

            $em = $this->getDoctrine()->getEntityManager();
            $em->persist($employee);
            $em->flush();

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

    return $this->render('HrmEmployeeBundle:Pages:add.html.twig', array(
                'form' => $form->createView(), 'status' => 'addEmployee',
            ));
}

所以我需要做的是应该有以下选项，

填写员工注册详细信息并创建登录（已经完成）
仅填写员工注册详细信息，无需为此创建登录信息。

所以第二个选项不适合我，它说Column'username'不能为null 我该怎样摆脱这个问题？

Answer 1

要回答第二个问题，请在addEmployeeAction中添加新员工的用户，删除以下行：

$user = new User();
$employee->setUser($user);

目前，$ employee使用空用户保存，没有用户名，因此MySQL不满意！通过删除这些行，只有在填写表单时才会创建用户！

Answer 2

如果要设置SQL字段optionnal，请添加nullable选项true：

oneToOne:
    User:
      targetEntity: Sys\UserBundle\Entity\User
      cascade: ["persist"]
      joinColumn:
        name: login_id
        referencedColumnName: id
        nullable: true

但是在你的情况下，它似乎你注册了一个没有用户名的用户，这是不合逻辑的...也许用户名字段工作不正常，请给我们更多细节。

有一个与两个实体相关联的表格。我需要让一个实体可选 - symfony 2？
