我已經(jīng)按照 Symfony文檔開發(fā)了一個基本的用戶注冊表。嘗試提交密碼和失敗登錄計數(shù)不能為空的表單時，我收到驗證錯誤：data.password       This value should not be nulldata.failedLogins   This value should not be nullRegistrationFormType 類：public function buildForm(FormBuilderInterface $builder, array $options){    $builder        ->add('firstname', TextType::class, ['label'=> false, 'attr' => ['placeholder' => 'First name']])        ->add('lastname', TextType::class, ['label'=> false, 'attr' => ['placeholder' => 'Last name']])        ->add('email', EmailType::class, ['label'=> 'Email address', 'attr' => ['placeholder' => 'Email address']])        ->add('plainPassword', PasswordType::class, [            'label' => 'Password',            'attr' => ['placeholder' => 'Must be at least 6 characters'],            'mapped' => false,            'constraints' => [                new NotBlank([                    'message' => 'Please enter a password',                ]),                new Length([                    'min' => 6,                    'minMessage' => 'Your password should be at least {{ limit }} characters',                    // max length allowed by Symfony for security reasons                    'max' => 4096,                ]),            ],        ])    ;}public function configureOptions(OptionsResolver $resolver){    $resolver->setDefaults([        'data_class' => User::class,    ]);}用戶實體：/*** @var string The hashed password* @ORM\Column(name="password", type="string", length=255, nullable=false, options={"fixed"=true})*/private $password;/** * @var int * * @ORM\Column(name="failed_logins", type="integer", nullable=false) */private $failedLogins;問題似乎是表單驗證器返回 false，因為它需要 'password' 和 'failedLogins' 字段。如代碼示例所示，我不想在表單中包含這些字段并在提交表單后處理它們...如果我向表單構(gòu)建器添加虛擬隱藏字段，則表單處理正常：->add('password', HiddenType::class, ['data' => 'abc'])->add('failedLogins', HiddenType::class, ['data' => 0])然而，這似乎不是正確的方法。任何有關(guān)為什么在表單生成器中未包含這些字段時會驗證這些字段的見解將非常感謝。
