我们使用symfony 4.4并使用sonata进行实体管理。我们实现了一个非常轻量级的用户管理,并且可以在用户编辑页面的第二个选项卡中为用户添加产品。所以现在管理员想要为用户分配产品,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,但设置为false根本没有帮助,因为这样字段就会被提交为空。
所以我尝试的解决方案是在我的admin类中使用preUpdate函数来防止这个错误。
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;
}
如果该字段为空,我们就使用现有的密码,这样添加产品和更新用户实体就没有问题了。
这将是很好的,但是在preUpdate函数之前就出现了触发错误。
所以给出的错误是
Expected argument of type "string", "null" given at property path "password".
所以给定的错误是: "在preUpdate没有任何效果的情况下
这里有什么解决方案?
全栈跟踪。

我可以在其他地方应用preUpdate的行为吗?
这里是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();
非常感谢你的帮助
重复类型的声明似乎不错。
您不应该在preUpdate中防止错误。
您的实体中的参数是可选的吗?
public function setPassword(?string $password): self
{
$this->password = $password;
return $this;
}
