如何在用户/编辑上为管理员提供 SF/Sonata RepeatedType (pw)

Question

我们正在使用 symfony 4.4 并使用奏鸣曲进行实体管理。 我们实现了一个非常轻量级的用户管理，并且还可以在用户编辑页面的第二个选项卡中向用户添加产品。 所以现在管理员想要将产品分配给用户，但问题是密码字段不允许这种行为。 首先密码字段是必需的，但将其设置为 false 根本没有帮助，因为该字段只是被提交为空。

所以我尝试的一个解决方案是在我的管理员 class 中使用 preUpdate function 来防止该错误。

    public function preUpdate($object)
{
    /** @var EntityManagerInterface $em */
    $em = $this->getConfigurationPool()->getContainer()->get('Doctrine')->getManager();
    /** @var UserRepository $repository */
    $repository = $em->getRepository(User::class)->find($object->getId());

    $password = $object->getPassword();
    if (!empty($password)) {
        $salt = md5(time());

        $encoderservice = $this->getConfigurationPool()->getContainer()->get('security.encoder_factory');
        $encoder = $encoderservice->getEncoder($object);
        $encoded_pass = $encoder->encodePassword($object->getPassword(), $salt);
        $object->setSalt($salt);
        $object->setPassword($encoded_pass);
    } else {
        $object->setPassword($repository->getPassword());
    }

    return $object;

}

因此，如果密码不为空 - 我们采用给定的值并更新密码。 如果该字段为空，我们使用现有密码，因此只需添加产品和更新用户实体就没有问题。

这很好，但触发错误出现在 preUpdate function 可以提供帮助之前。

所以给定的错误是：

Expected argument of type "string", "null" given at property path "password".

没有 preUpdate 生效。

这里的解决方案是什么？

我可以以某种方式将 preUpdate 的行为应用到其他地方吗？

这是formMapper：

        $formMapper
        ->tab("Information")
            ->add('email', TextType::class, [
                'attr' => [
                    'readonly' => $emailDisabledState,
                ],
            ])
            ->add('password', RepeatedType::class, [
                'type' => PasswordType::class,
                'invalid_message' => 'The password fields must match.',
                'options' => ['attr' => ['class' => 'password-field']],
                'required' => false,
                'first_options'  => ['label' => 'Password'],
                'second_options' => ['label' => 'Repeat Password'],
            ])
            ->add('isActive', BooleanType::class)
            ->add('roles', ChoiceType::class, [
                'choices' => array_flip($flattendRoles),
                'multiple' => true,
                'expanded' => false,
            ])
            ->end()
        ->end()
        ->tab("Products")
            ->add("products", EntityType::class, [
                'class' => Product::class,
                'multiple' => true
            ])
            ->end()
        ->end();

非常感谢帮助

重复类型的声明似乎很好。

您不必防止 preUpdate 中的错误。

您的实体中的参数是可选的吗？

    public function setPassword(?string $password): self
    {
        $this->password = $password;

        return $this;
    }
